Marble Isles

Privacy Policy

Effective November 5, 2026 · iPhone, iPad and Android

Marble Isles (the "Game") is made by Greenfield Labs LLC ("we", "us"). This policy explains what information the Game uses, why, and the choices you have. In short: there's no account with us, we don't ask for your name or email, and we don't run our own servers. Your saved game is on your device and, if your device is signed in to iCloud (iPhone and iPad) or Google Play Games (Android), a copy is kept in your own iCloud or Google account so your other devices can continue; we can't see that copy. Game Center or Google Play Games show the achievements you earn, and on iPhone and iPad Game Center ranks your Daily Challenge scores. The first time you open the Game, it asks for your year of birth, which stays on your device. The Game uses Unity Gaming Services, which receives the gameplay, device and purchase information described below, and it shows ads from ironSource Ads and Unity Ads through Unity LevelPlay. Google's consent form asks players in the EEA, the UK and Switzerland whether ads may be personalised, and lets players in US states with privacy laws opt out of the sale or sharing of their information. Analytics is on by default and can be turned off, except in the EEA, the UK and Switzerland, where it's off until you turn it on. On iPhone and iPad, Apple's tracking prompt asks whether ads may use your advertising identifier, but only where personalised ads are allowed; on Android, your device's ad settings apply. Players under 13, and in the EEA, the UK and Switzerland players under their country's age of digital consent, send no analytics and never see the consent form or the tracking prompt, and the Game tells the ad networks to treat them as children.

Information the Game keeps on your device

Your saved game is a file on your device. It holds your levels, stars and best scores; coins, lives and boosters; the Shooters and Marble Sets you own and use; daily reward and win streaks, the piggy bank and offer timers; your Winter Trail snowflakes and rewards; your Daily Challenge for the day (the runs you've used, your best score and the coins it paid); the achievements you've earned and the totals they count (such as marbles popped, your best chain and best combo); tutorials seen; your settings (music, sound, haptics, colorblind symbols, aim mode and "Share analytics", including whether you changed that switch yourself); the year of birth you entered; when you first and last played, how many sessions you've played and recent failed attempts; ad counters; whether the Game has asked for notification permission; how many times the Game has asked the store to show its rating prompt, and when and in which version it last did; and your purchase records (the items you own and the IDs of up to 200 recent App Store or Google Play transactions). For cloud save, it also keeps a ledger of the coins, boosters and marbles popped that each of your installations has added and spent. Each installation is named in it by a code made on your device from a short one-way hash of the Device ID (see Device features) and a random ID created when the Game is installed, which the Game keeps in a separate small file.

The Game also keeps a copy of its latest remote settings. Google's consent software stores your answers to its consent form on your device, in the industry's standard formats (the IAB TCF, GPP and US Privacy strings), where the ad networks read them. Unity's software stores its own identifiers on your device: an installation ID, an analytics user ID, and the anonymous player ID and session described below. It also keeps any analytics events that haven't been sent yet. Game Center and Google Play Games keep their own sign-in information.

Deleting the Game deletes these files from your device, but not the cloud copy in your iCloud or Google Play Games account (see Cloud save, achievements and leaderboards). The Game doesn't exclude its files from backups, so they're included when your iPhone or iPad is backed up to iCloud or to a computer, or when Android backs up your apps to your Google account, and they come back if you restore that backup (on Android, also when you set up a new phone from it). Apart from that and the cloud copy, we can't recover them. Summaries of your progress are sent to Unity, as described below.

Cloud save, achievements and leaderboards

If your device is signed in to iCloud (iPhone and iPad) or Google Play Games (Android), the Game keeps a copy of your saved game in your own account: in iCloud key-value storage under your Apple Account, or in Saved Games under your Google Play Games profile. Another device signed in to the same account picks it up, and the devices merge their progress so that what you've earned on each one is kept. Apple and Google store the copy under their own privacy policies. We can't see it, and it never passes through any server of ours. iPhone and iPad don't share a copy with Android.

The copy holds your saved game as described above, except your year of birth and your settings (including "Share analytics"), which never leave the device; another device therefore asks the age question again. It includes the installation codes in the ledger, and also some records that only matter on the device that made them, such as ad and offer timers and purchase transaction IDs, which your other devices ignore. Your answers to Google's consent form aren't part of it either.

On iPhone and iPad, the Game uses iCloud without a sign-in of its own: Settings shows "iCloud save" and whether it's on. On Android, the Game signs in to Google Play Games automatically when it starts, and Google shows its own sign-in banner; if you're signed out, tapping the "Cloud save" row in Settings signs you in. Settings then shows your Play Games name, on your device only; the Game doesn't send it anywhere. The Game has no switch to turn cloud save off and no button to delete the copy: it's used while your device is signed in to iCloud or Google Play Games. Deleting the Game doesn't delete the copy, and reinstalling the Game brings your progress back. On Android, Google Play Games' own settings can delete the Game's data from your Play Games profile.

The Game has 40 achievements. It earns and saves them itself and shows them on its Awards screen. If you're signed in to Game Center (iPhone and iPad) or Google Play Games (Android), the Game sends the achievements you earn and your progress toward them to Apple or Google, which show them in Game Center or Play Games under their own privacy policies. On iPhone and iPad, the Game signs in to Game Center quietly when it starts, using the account already on your device, and offers Game Center's sign-in screen only from the Awards screen or the Daily Challenge's Leaderboard button.

The Daily Challenge (from level 15 on) is one stage a day, the same for every player. On iPhone and iPad it's ranked on a daily leaderboard: when a run ends, the Game sends its final score to the "Daily Challenge" leaderboard in Game Center, if you're signed in, and Apple keeps each player's best score of the day. Your score is visible to other players there, with your Game Center name and profile, as Game Center's own settings allow. The Game doesn't show rankings itself: the Leaderboard button opens Game Center's own page. If you aren't signed in, no score is sent. On Android the Daily Challenge has no leaderboard for now, and no score is sent to Google Play Games.

Unity Gaming Services

The Game has no servers of its own. Its online features run on Unity Gaming Services, provided by Unity Technologies, in a Unity project that belongs to us. The Game's own code doesn't connect to the internet. The data described in the next sections is sent by Unity's software built into the Game, and we see it in our Unity dashboard. Unity processes it for us (and, for crash and performance data, also for its own purposes, as described below) under Unity's privacy policy. Unity is based in the United States and may process the information there or in other countries (see Transfers outside Europe). The Game's other connections are to the ad networks, Google's consent form, Apple's and Google's stores, and iCloud, Game Center and Google Play Games, as described in this policy.

Every time the Game starts, for every player and wherever they are, and whether or not "Share analytics" is on, it signs in to Unity anonymously and fetches its remote settings. The sign-in uses no name, email or password. It creates a random Unity player ID. This ID is kept on your device and normally stays the same until you delete the Game. It is attached to the remote settings, analytics and purchase information described in this policy.

Remote settings (Unity Remote Config) let us adjust things like in-game coin prices, rewards, life refill times, ad frequency, offers, the Daily Challenge, seasonal events and when the rating prompt may appear, without an app update. The request includes your Unity installation ID and player ID. It also includes device details: model, operating system, language, screen size and resolution, processor, memory, graphics chip, app version, install source and whether the device is jailbroken or rooted. It ends with a summary of your progress: levels completed, highest level reached, number of play sessions, days since you installed the Game, whether you've ever made a purchase, and whether your device is one of our test devices. We use these details to tune settings for groups of players, such as new players or players who have made a purchase.

Analytics

The Game can send gameplay events to Unity Analytics. We use them to see how the Game is played, balance its difficulty and fix problems. Whether they're sent depends on where you are and how old you are, and you can always change it with the "Share analytics" switch in Settings:

Where you are, for this purpose, is worked out on your device (see Privacy choices), and a choice you made with the switch is kept if that changes. Nothing is sent until you've answered the age question. Outside the EEA, the UK and Switzerland, events from before your answer are held by the Game and sent once you've answered, if you're 13 or older. In the EEA, the UK and Switzerland, events from before you turn the switch on are dropped and never sent later.

Each time the Game starts, it sends a summary: your highest level, levels completed, total stars, coin balance, lives, number of sessions, days since install, whether you've made a purchase, whether you have Remove Ads, whether your device is one of our test devices, and the label of any settings test you're part of. While you play, it sends events for levels started, completed and failed (such as the level, the attempt, the goal, score, stars, time played, shots, continues, best combo and coins won, or how far you got and why the level ended); continues offered and used; boosters used; tutorials seen; coins earned and spent (amount, reason and balance); running out of lives; world chests; shop visits; purchases started, failed and completed (product and price); daily rewards; Shooters and Marble Sets unlocked and equipped; offers shown; ad placements shown and rewarded; win streaks lost; Daily Challenge runs started and finished (the day, the stage, the run number, the score, whether you lasted the full two minutes, how long you played and your best score of the day); each time the Game asks the store to show its rating prompt (the level, why, and how many times it has asked); and, during a winter event, your progress on its trail (the event, the day, your snowflakes and how far you've got), snowflakes earned, rewards claimed, the trail being opened, stages started and finished (the stage, the run, the score, stars, whether you won, how long you played and continues used) and mini-game plays (the type of play, the score, stars, snowflakes, shots and how long you played).

Unity's analytics software also adds its own events. It reports when the Game is first run, when it starts, while it's running and when it stops, and it describes your device. It also records each App Store or Google Play purchase with its receipt. These events, too, are sent only when analytics may be sent as described above.

With these events Unity receives a random installation ID and your Unity player ID. It also gets the "Device ID" shown in the Game's Settings: on iPhone and iPad, your device's vendor identifier (IDFV); on Android, an identifier Unity derives from the Android ID (see Device features). It gets the device model, operating system, language and region, processor, graphics chip, memory, screen size and resolution, battery level and volume setting, and the app version and build. Unity also works out your country from your IP address. Analytics events don't include your name, email address, year of birth or advertising identifier.

Turning "Share analytics" off stops these analytics events from then on; in the EEA, the UK and Switzerland, it withdraws your consent. It doesn't stop the anonymous sign-in, remote settings, purchase information or crash data described in the other sections, which are sent either way. It also doesn't delete data already sent. To ask for that, contact us (see Your rights).

Crash and performance data

The Game has Unity's engine diagnostics turned on. Unity's game engine collects technical data about crashes, performance and stability from the Game on your device, with basic details about your device and the app, and sends it to Unity, whether or not "Share analytics" is on and wherever you are. We use it in our Unity dashboard to find and fix problems, and Unity also uses it to improve its engine. Separately, you may have chosen to share analytics with app developers in iOS Settings (Privacy & Security > Analytics & Improvements). If so, Apple gives us crash reports and app usage data for the Game. On Android, if you've chosen to share usage and diagnostics data with Google, Google gives us crash and performance reports for the Game through Google Play Console.

In-app purchases

Purchases are processed by Apple through the App Store on iPhone and iPad, and by Google through Google Play on Android. We never see or store your payment details. The store tells the Game whether a purchase succeeded, and the Game records it on your device.

"Restore Purchases" (in the Shop and the Shooters screen, and "Restore" in Settings) restores seven one-time purchases: Remove Ads, the Starter Pack, Premium Pack and Legends Pack, and the Prism Core, Star Dragon and Solar Phoenix Shooters. The Game also checks the store for them each time it starts. Restoring marks them as owned again, turns ads off again for Remove Ads, and gives back their Shooters, including the Premium Pack's Golden Idol. It does not give back the coins, boosters or unlimited lives that came with a pack. Coin packs, the Booster Bundle, Lives Bundle, Piggy Bank, Hard Level Pack, Boss Pack and Welcome Back Pack are used up when you buy them and can't be restored by the store. Coins and boosters you bought are part of your saved game, though, so they come back with your cloud copy on a device that uses the same iCloud or Google Play Games account (see Cloud save, achievements and leaderboards).

Remove Ads is a one-time purchase, not a subscription. It turns off banner and between-level ads for good (see Advertising) and, like the other one-time purchases, comes back with "Restore Purchases", after you reinstall the Game and on your other devices that use the same Apple Account or, on Android, the same Google account.

When you buy something, Unity's purchasing software sends Unity a record of each step of the purchase: when you start it, when you pay, and whether it failed or was delivered. A record is sent as soon as you tap to buy, even if you then cancel. The records include the product's ID, name, description, price and currency; for paid purchases, the store's transaction IDs and receipt (on iPhone and iPad, also Apple's signed transaction record and whether you bought the item yourself or through Family Sharing; on Android, Google Play's order ID and purchase token); your Unity installation, analytics and player IDs; on iPhone and iPad, your device's vendor identifier (IDFV); and your device model, operating system, language and region settings, when the device last started up, its total storage size and when the Game was installed.

Unity's purchasing software sends a similar message, with the same identifiers and device details, when the Game signs in to Unity. At each launch it also fetches its own settings from Unity, sending your installation ID and the app version. These are sent whether or not "Share analytics" is on. When analytics may be sent (see Analytics), Unity Analytics also receives the purchase details listed there.

Advertising

The Game shows ads through Unity LevelPlay, from ironSource Ads and Unity Ads and, on Android, Google AdMob, with ironSource's Ad Quality SDK checking the ads that are shown. There are rewarded ads that you choose to watch (for example to continue a level, double your coins, get a free life, play the Daily Challenge again or get another Ice Ring play), a banner at the bottom of the map screen, and an ad between levels (by default only after you've completed 6 levels, at most every second level end and at least 150 seconds apart). There are never ads while you play a level. None of this starts until you've answered the age question and, for players the Game doesn't treat as children, Google's software has said whether its consent form is needed (see Privacy choices).

On iPhone and iPad, the Game then shows Apple's App Tracking Transparency prompt, before any ads load, to players who may be shown personalised ads: outside the EEA, the UK and Switzerland, players 13 and older; there, only players who have agreed to personalised ads in Google's consent form. If you allow tracking, the ad networks may use your advertising identifier (IDFA) to personalise ads and measure them. If you decline, or aren't asked, ads aren't personalised with your advertising identifier. You can change your answer at any time in iOS Settings > Privacy & Security > Tracking.

On Android there is no tracking prompt. For players the Game doesn't treat as children, the ad networks may use your device's advertising ID to personalise ads and measure them, within your answers to Google's consent form where it's shown. You can reset or delete your advertising ID at any time in your device's settings (on most devices, Settings > Privacy > Ads, or Settings > Google > Ads); once it's deleted, ads aren't personalised with it. Where your device supports them, the ad networks may also use Android's ad privacy features (ad topics and ad measurement), which you can turn off in your device's ad privacy settings.

In the EEA, the UK and Switzerland, the ad networks read your answers to Google's consent form and personalise ads only if you agreed. Where Google's form isn't needed, the Game tells the ad networks that they have consent to use your information for ads; your tracking answer on iPhone and iPad, and your device's ad settings on Android, still decide whether your advertising identifier may be used. If you've opted out of the sale or sharing of your information in a US state (see Privacy choices), the Game tells the ad networks not to sell or share it. The Game also tells the ad networks whether to treat you as a child. For children, see Children.

Whenever ads are requested, the ad networks may collect information such as your IP address, device model and settings, device identifiers (such as the vendor identifier (IDFV) on iPhone and iPad, or the app set ID on Android), and how you interact with ads. Their use of this information is governed by their own privacy policies, including Unity's privacy policy and, for Google AdMob on Android, Google's privacy policy.

Buying Remove Ads turns off banner and between-level ads for good. Reward buttons then say so (for example "Free (No Ads)" or "Claim") and give the reward without any ad. No ad network is asked for those rewards.

Privacy choices (EEA, UK, Switzerland and US states)

For its privacy messages the Game uses Google's User Messaging Platform, a consent tool from Google that is certified for the IAB Transparency & Consent Framework (TCF v2.2). At each launch, after the age question and only for players it doesn't treat as children, the Game asks Google's software whether a message is needed where you are. Google decides this itself, from your location as it works it out (for example from your IP address); elsewhere no message appears. To do this and to show its form, Google's software connects to Google and receives information such as your IP address and details about your device and the app, and it stores your answers on your device. Google handles this under Google's privacy policy. On iPhone and iPad, Google only provides the form. On Android, Google is also an ad network: Google AdMob can show ads through Unity LevelPlay (see Advertising).

In the European Economic Area, the UK and Switzerland, Google's form asks whether the ad networks (ironSource Ads and Unity Ads through Unity LevelPlay and, on Android, Google AdMob) may store and read information on your device and use it to personalise and measure ads. It lists the purposes and the ad partners, and lets you agree to them or refuse them. Ads are shown either way; if you refuse, they aren't personalised. Your answer is stored on your device, where the ad networks read it. The Game itself reads only whether you agreed to personalised ads, to decide whether to show Apple's tracking prompt on iPhone and iPad.

No ad software starts until Google's software has answered. If it can't be reached (for example with no connection), players outside the EEA, the UK and Switzerland get ads as usual. There, an earlier answer stays in force; if you haven't answered before, the Game shows no ads during that session and asks again at the next launch.

In US states with privacy laws, Google's message lets you opt out of the sale or sharing of your personal information and of targeted advertising. If you opt out, the Game tells the ad networks not to sell or share your information. It tells them that for every child too.

Where Google says you should be able to change your answers (for example in the EEA, the UK and Switzerland, or in US states with privacy laws), Settings shows a "Privacy choices" button. It opens Google's form again, and a new answer applies to the ads requested from then on. Your answers stay on each device: changing them on one device doesn't change them on your others, and they aren't part of the cloud copy.

Separately, the Game works out on your device whether you're in the EEA, the UK or Switzerland, to set the age of digital consent (see Children) and the analytics default (see Analytics): on iPhone and iPad from your App Store country and your device's region setting, and on Android from your device's region setting and the countries of your SIM card and mobile network, which needs no permission. If any of them is in the EEA, the UK or Switzerland, the Game treats you as being there, with the highest age of digital consent among them; if none is, or none can tell, as being outside. The Game doesn't use your device's location services, and nothing is sent anywhere for this. Because Google decides about its form separately, the two can differ, for example when you travel. The ages the Game uses are:

Territories that are part of these countries, such as France's overseas departments, the Canary Islands, Åland and Svalbard, use their country's age.

Notifications

The Game has one reminder: "Lives are full!", which tells you when your lives have refilled. The Game asks for notification permission once, after you first beat level 3, not when you open it. If you allow it, the reminder is scheduled on your device whenever your lives aren't full and cancelled when they are. It isn't shown while you're playing. On Android 12 and earlier, apps don't need to ask, so the reminder is on unless you turn it off; on Android, a scheduled reminder is also set again after your phone restarts. There are no push notifications: nothing is sent from a server, and nothing about notifications leaves your device. To turn the reminder off, go to Notifications in your device's Settings. The Game has no separate switch for it.

Device features

Apart from notifications and, on iPhone and iPad, Apple's tracking prompt (see Advertising), the Game asks for no permissions. On Android it also declares permissions that don't ask you anything: internet and network access, vibration, purchases through Google Play, the advertising ID and Android's ad privacy features (for the ad networks, see Advertising), and running after a restart (to set the reminder again). Reading your SIM card's and mobile network's country (see Privacy choices) needs no permission. It doesn't use your camera, microphone, photos, contacts or location. You can turn haptics (vibration) off in the Game's Settings. Settings also shows your "Device ID". On iPhone and iPad it's your device's vendor identifier (IDFV), which iOS shares with all apps from the same developer on your device. On Android it's an identifier Unity derives from the Android ID that your device gives the Game; it normally stays the same if you reinstall the Game and changes if the device is reset. Tapping it copies the ID so you can send it to us with a support or privacy request. The Game's Settings link to this policy ("Privacy Policy"), Apple's standard Terms of Use ("Terms of Use") and our support email ("Support"), which open in your browser or mail app, and "Rate Marble Isles" opens the Game's page in the App Store or Google Play to write a review.

Now and then, after a three-star win or your first win over a boss, the Game may ask iOS or Google Play to show the store's own rating prompt: by default only after you've completed 15 levels and at least a day after you first opened the Game, at most once per version of the Game and at most once every 90 days. Apple or Google decides whether the prompt actually appears; it belongs to them, and what you enter there goes to Apple or Google, not to us. The Game only records that it asked (see Information the Game keeps on your device and Analytics).

What we don't do

Beta testing

If you test a pre-release version through Apple TestFlight or a Google Play testing track, Apple or Google shares limited information with us, such as your name or email address (as entered in your invitation), device and app version, crash reports and any feedback or screenshots you choose to send. We use it only to improve the Game. See TestFlight & Privacy and Google's privacy policy.

TestFlight builds otherwise work as described in this policy, except that most of them show no real ads: no ad network is contacted, Google's consent form and Apple's tracking prompt aren't shown, and reward buttons give the reward after a short pause without showing anything. Builds made as the App Store release, and most builds on Google Play's testing tracks, show real ads as described in Advertising. A build that tests a seasonal event early shows no real ads either. Purchases in TestFlight use Apple's test environment, and Google Play testers we've added as license testers make test purchases; neither is charged, but Unity still receives the purchase information described above. If you send us your Device ID, we can register your phone as a test device. The Game then sends its analytics and remote settings requests to a separate testing area of our Unity project, and a Developer menu appears in Settings. A test device shows no real ads unless you switch on live ads from ironSource Ads and Unity Ads for testing in that menu. If the Game doesn't treat you as a child, you can also copy your advertising identifier there for us to register with the ad networks. On iPhone and iPad, either one shows Apple's tracking prompt. Live ads let those networks collect the information described in Advertising.

Children

The Game is a general-audience puzzle game that children may also play. The first time it's opened (and once for players who installed an earlier version), it asks for the player's year of birth from a neutral list of years, before any ads, analytics, consent form or tracking prompt start. The answer is kept only in the saved game on the device and is never sent anywhere; it isn't part of the cloud copy, so each device asks. The Game treats the player as a child if the year means they may be under 13 (this year minus the year of birth is 13 or less) or, in the EEA, the UK and Switzerland, under their country's age of digital consent (this year minus the year of birth is that age or less; see Privacy choices). This is worked out again at every launch, so players grow out of it. For a child, the Game:

• never shows Google's consent form or Apple's tracking prompt, so on iPhone and iPad the ad networks don't get the advertising identifier, and on Android tells them not to use the device's advertising ID;
• tells Unity LevelPlay, ironSource Ads and Unity Ads and, on Android, Google AdMob to treat the player as a child under the U.S. Children's Online Privacy Protection Act (COPPA), that the player hasn't consented to personalised ads, and not to sell or share the player's information, so the ads shown aren't personalised;
• sends no analytics events, and doesn't show the "Share analytics" switch.

The anonymous Unity sign-in, remote settings, purchase records and crash data described above work the same way for every player, because the Game needs them to run, keep its settings up to date, deliver purchases and fix problems. We use them only for those purposes. Cloud save, achievements and the Daily Challenge leaderboard also work the same way for every player signed in to iCloud, Game Center or Google Play Games: these are Apple's and Google's services in the player's own account, used under their rules for children's accounts, and nothing from them reaches us. The rating prompt, when it appears, is Apple's or Google's own. Purchases go through Apple or Google, where parents can require approval for purchases (Ask to Buy with Apple's Family Sharing, or purchase approvals in Google Play and Google Family Link).

The answer can't be changed in the Game. Deleting the Game deletes it, and the Game asks again after it's reinstalled (unless a device backup that includes it is restored). If you believe a child has used the Game, contact us with the Device ID from the Game's Settings, and we'll help delete the data linked to it.

How long information is kept

Who is responsible

Greenfield Labs LLC is responsible for the information this policy describes that the Game handles for us (under the GDPR, the UK GDPR and the Swiss data protection law, we're its "controller"). You can reach us at support@greenfieldlabs.llc. Unity processes the analytics, remote settings and anonymous sign-in for us. Unity also receives the crash and performance data and the purchase records described above, and uses crash and performance data for its own purposes too; Unity's ad services (Unity LevelPlay, ironSource Ads and Unity Ads) handle what their software collects under Unity's privacy policy. Google provides the consent form and, on Android, Google AdMob under its own privacy policy. Apple and Google handle purchases, iCloud, Game Center, Google Play Games and their rating prompts under their own privacy policies (Apple, Google).

Why we use your information (EEA, UK and Switzerland)

Where the GDPR, the UK GDPR or the Swiss data protection law applies, these are the reasons (legal bases) for each kind of use:

You can withdraw your consent at any time, as easily as you gave it: turn off "Share analytics" for analytics, change your answers with "Privacy choices" in Settings for ads, and turn tracking off in iOS Settings > Privacy & Security > Tracking. Withdrawing stops the use based on consent from then on. It doesn't affect what was done before, and it doesn't delete data already sent (see Your rights). Where we rely on legitimate interest, you can object; see Your rights.

You don't have to give us any information to play. The age answer is required, but it stays on your device. Analytics and personalised ads are optional. The other uses described in this policy are part of how the Game runs.

Transfers outside Europe

Unity and Google may process information in the United States and other countries outside Europe, where data protection laws may differ from yours. Unity's privacy policy for game players, which covers Unity's analytics and ad services, says Unity uses the European Commission's Standard Contractual Clauses for transfers of personal data from the EEA and the UK to countries without an adequacy decision. Apple and Google explain their own transfers in their privacy policies.

Your rights

Depending on where you live (for example under the GDPR in the EEA, the UK GDPR, the Swiss data protection law, or the CCPA in California and other US state laws), you may have rights to access personal information about you, to correct or delete it, to get a copy of it, to restrict or object to its use (including use based on our legitimate interest), to withdraw consent, to opt out of its sale or sharing or of targeted advertising, and not to be treated differently for using these rights. For the Game, that information is the pseudonymous data held for us in Unity Gaming Services: your installation ID, Unity player ID and Device ID; device details; gameplay and purchase events; the progress summaries sent with remote settings; and your approximate country. We don't hold your name or email unless you write to us (we then use them only to reply) or Apple or Google shares them because you joined our beta test.

Much of this you can do in the Game: "Share analytics" in Settings stops analytics (and withdraws your consent where it was needed), "Privacy choices" in Settings, where it's shown, changes your ad choices and US opt-outs, and deleting the Game removes the data on your device, including your age answer and Google's consent answers (deleting the Game doesn't delete the cloud copy; see Cloud save, achievements and leaderboards). On iPhone and iPad you can stop ads from using your advertising identifier by turning tracking off in iOS Settings > Privacy & Security > Tracking, and on Android by deleting your advertising ID in your device's settings.

For anything else, email us at the address below. Include the Device ID shown in the Game's Settings (tap it to copy) so we can find the data linked to your install. We'll handle the request with Unity and answer within the time the law allows (under the GDPR, normally one month). The cloud copy, achievements and leaderboard scores are in your own Apple or Google account, which we can't reach: Apple and Google handle requests about them, and about your purchase history, at privacy.apple.com and myaccount.google.com. The ad networks hold their own data about the ads shown to you, and requests about it can also be made to Unity under its privacy policy; Google handles requests about its consent form and Google AdMob under its privacy policy. We don't sell your personal information.

If you're in the EEA, the UK or Switzerland and think we've used your information unlawfully, you can complain to a data protection supervisory authority, in particular in the country where you live or work or where the problem happened: in the EEA your national data protection authority, in the UK the Information Commissioner's Office (ICO), and in Switzerland the Federal Data Protection and Information Commissioner (FDPIC). We'd be glad if you contacted us first, so we can try to help.

Changes

If this policy changes, we'll update this page and its effective date, before any version of the Game that collects information in a new way is released.

What's new in this version: Google AdMob is named as an ad network on Android, where it has shown ads since October 27, 2026; how long information is kept (see How long information is kept); the Daily Challenge leaderboard is described as iPhone and iPad only, since Android has none for now; and the analytics events and the rewarded ad of the Winter Trail event, for Marble Isles 1.2.0 (see Analytics and Advertising).

New in the November 3, 2026 version, for Marble Isles 1.0.1: cloud save in your own iCloud or Google Play Games account, achievements in Game Center and Google Play Games, and the Daily Challenge with its daily leaderboard (see Cloud save, achievements and leaderboards); Google's consent form for the EEA, the UK and Switzerland and for US states, and the "Privacy choices" button (see Privacy choices); each country's age of digital consent in the EEA, the UK and Switzerland, below which players are treated like players under 13 (see Children); analytics off by default in the EEA, the UK and Switzerland until you turn it on, and two new analytics events for the Daily Challenge and one for the rating prompt (see Analytics); Apple's tracking prompt only where personalised ads are allowed (see Advertising); the stores' own rating prompt and the "Rate Marble Isles" button (see Device features); and new sections on who is responsible, legal bases, transfers outside Europe and your rights in Europe.
