Greedy Magnet ("the game") is a casual arcade game. This policy explains what data the game uses, why, and the choices you have.
The game saves your best score, your highest bomb count, the total of your scores (used to unlock magnet skins), the skin you chose, your nickname, and your settings (sound, music, reduced motion, vibration) on your device. This data is not sent to us unless you use the online leaderboards described below. Uninstalling the game or clearing its data removes it.
The game shows two global leaderboards (score and bombs). To run them, the game uses Google Firebase services operated by Google LLC:
An anonymous account identifier created by Firebase Authentication. You do not sign in and we do not ask for your email, phone number or real name. → Keeps your leaderboard entry tied to this installation of the game.
Your nickname → Shown publicly to other players on the leaderboards. Do not use your real name or other personal information in your nickname.
Your best score, highest bomb count, the duration of the run that set them, and the times they were achieved → Ranking, and basic checks that a record is plausible.
Device integrity tokens from Firebase App Check (Google Play Integrity) and technical identifiers used by Firebase SDKs → Protecting the leaderboards from automated abuse and fake requests.
Reports you send about another player's nickname (the reported entry, your anonymous identifier and the time) → Reviewing offensive nicknames.
A Firebase Cloud Messaging registration token for this installation. The game never sends you notifications with it. → Once a day we ask Google whether the token is still registered. When it is not, the game was uninstalled or its data cleared, so we delete that player's online data (see section 3).
Data is sent over encrypted connections (HTTPS) and stored in Google Cloud in the United States (region us-central1). Google processes it on our behalf under its data processing terms, including the Standard Contractual Clauses for transfers from the European Economic Area, the United Kingdom and Switzerland.
We do not sell your leaderboard data, do not use it for advertising, and do not share it with third parties other than Google as our service provider. Usage statistics and crash reports are described in section 8, and advertising, with its own data, in section 7.
Leaderboard data is kept for as long as it is needed to run the leaderboards, until you delete it. It is also deleted automatically, within about two days, after the game is uninstalled or its data is cleared on your device, because that anonymous identity can no longer be used; your nickname then becomes available to other players. If you do not open the game for 270 days, your leaderboard data and anonymous account are deleted in the same way; the records saved on your device stay, and if you open the game again later it joins the leaderboards as a new player with those records. Reports are kept while they are needed for review. Data collected by advertising providers (section 7) is kept by those providers under their own policies, not by us. If you delete your online data, your identifier is removed from any reports you sent or that concern you.
In the game: Settings → Online data → DELETE. This removes your nickname and records from the online leaderboards and deletes your anonymous account. Records saved on your device stay on your device. Your entry disappears from the public top 100 at the next leaderboard update (at most about 30 minutes).
By email: if you can no longer open the game, email nguyenvanchiit2001@gmail.com with the subject "Delete Greedy Magnet data" and your nickname. Because the game has no login, we may ask for details that help us find your entry, and we will reply within 30 days.
Depending on where you live (for example under the GDPR in the EU/UK), you may have the right to access, correct, delete or object to the processing of your personal data, and to complain to a data protection authority. We rely on our legitimate interest in providing a fair global leaderboard, and on performing the service you choose to use. Where the game asks for your consent to advertising (section 7), you can withdraw it at any time. Contact us at the email above to exercise these rights over data we hold; for data held by advertising providers, use their tools and the links in section 7.
The game is not directed at children under 13, and we do not knowingly collect personal data from them. The game does not tell advertising providers that its users are children. If you believe a child has provided personal data through a nickname, contact us and we will delete it.
The game is free and shows advertising. We use Google AdMob, a service of Google LLC (Google Ireland Limited for users in the European Economic Area and the United Kingdom), as the advertising platform. AdMob mediation can also request ads from another ad network, Unity Ads (Unity Technologies). The game shows:
a banner at the bottom of the screen;
a full-screen ad between rounds, only after a round ends and at most once every 5 minutes;
an optional rewarded video that you can choose to watch to revive once and continue a round after you crash. If you skip it, the round ends as usual.
Ads are never shown while you are playing; the revive offer appears only after you crash.
To select, deliver, limit and measure ads and to prevent ad fraud, these providers may collect and use, from your device:
The Android advertising ID (you can reset or delete it in your device settings) → Showing and personalising ads, frequency limits, measuring and attributing ads, fraud prevention.
IP address and the approximate location derived from it → Choosing ads, applying local laws, fraud prevention. We do not ask for or use precise location.
Device and app information such as device model, operating system version, language, screen size, app version and network type → Delivering ads that fit your device, diagnostics and performance of the ad code.
Ad interactions such as ads shown, clicked or watched to the end, and crash and diagnostic data from the ad code → Measuring ad performance, paying for ad views, detecting invalid traffic.
This data is sent to and processed by Google and by the ad networks that bid on or fill the ad, who act as independent controllers of the data they receive. We do not receive your advertising ID, and we do not sell your personal information. We see only aggregated ad reports from AdMob.
Your choices.
European Economic Area, United Kingdom and Switzerland: when you first open the game, a consent form from Google's User Messaging Platform asks whether you agree to the use of your data for personalised advertising. If you do not agree, you can still play and may still see ads, but they are not personalised with that data.
United States (states with privacy laws) and similar regions: where the law requires, the same form tells you about the use of your data for advertising and lets you opt out of its sale, sharing or use for targeted advertising.
Changing your choice: open Settings → Ad privacy in the game to review or change it. This link appears only where the law of your region requires it.
On your device: in Android Settings → Privacy → Ads you can delete your advertising ID or opt out of ads personalisation.
The form is never shown in the middle of a round. Whether or not you consent, the game stays fully playable.

To understand how the game is played and to fix problems, the game uses two more Firebase services from Google LLC:
Google Analytics for Firebase: an app-instance identifier created by Firebase, when you open the game and how long you play, and what happens in each round (score, bomb count, round length, whether you revived, whether you set a new record). Also device model, operating system version, language, country derived from your IP address, and app version. → Counting how many players come back, finding where rounds become too hard or too easy, and improving the game.
Firebase Crashlytics: a crash report when the game crashes or hits an error: the stack trace, device model, operating system version, free memory and app version, tied to a Firebase installation identifier. → Finding and fixing crashes.
Analytics does not use the advertising ID, is not used for advertising, and is not linked to your leaderboard nickname. In the European Economic Area, the United Kingdom and Switzerland it is switched on only if you agree in the consent form described in section 7 (consent to store and access information on your device); you can change this in Settings → Ad privacy. Elsewhere it is on. Crash reports are sent for every player, because we rely on our legitimate interest in keeping the game working. Google keeps Analytics data for 2 months (event-level data) and Crashlytics reports for 90 days.
We may update this policy when the game changes. The new version will be posted on this page with a new effective date.
