Privacy Policy
Effective 21 October 2026
Numeris is a number game. You can play it without an account, an email address or a real name. It keeps only what it needs to run the ranking and, in the mobile apps, to show ads and to find out when the game crashes.
- Anonymous player ID
- Ranking name & score
- Ads on Android & iOS
- Crash reports
- No account
- No location
- No contacts
- No analytics
Who we are
Numeris is made and published by giacomoto (“we”, “us”). We are the data controller for the information described here. You can reach us at ask@giacomoto.dev.
This policy covers the Numeris apps for Android and iOS and the web version of the game.
What the game keeps
| What | Where | Why |
|---|---|---|
| Anonymous player ID | Firebase | A random identifier created the first time you open the ranking or save a score. It lets you update your own ranking line and nobody else’s. It is not linked to your name, email or phone number. |
| Ranking entry | Firebase | Only if you choose to save a score: the name you type (3–12 letters, digits or spaces), your score, rows cleared, level reached, and the time it was saved. This entry is public: every player can see it on the ranking. |
| App integrity check | Firebase | Firebase App Check confirms that requests to the ranking come from a genuine copy of the game, to keep forged scores off the board. |
| Crash reports | Firebase Crashlytics | Android and iOS only. If the app crashes, a report is sent so we can find and fix the fault: what went wrong in the code, the time, the app version, your device model and operating system version, technical device state (such as free memory and orientation), and a random installation ID. It does not include your ranking name or anything you typed, and it is not linked to your player ID. The web version sends no crash reports. |
| Your settings | Your device | The last name you used for the ranking, whether sound is on, and whether you have been offered the tutorial. Stored only on your device and never sent to us. |
| Advertising data | Google AdMob | Android and iOS only. See section 03. |
The game does not collect your location, contacts, photos, microphone or camera, and it does not use analytics tools.
Nothing you type into the game is used for anything except the ranking name you choose to submit. Please don’t use your real name or anything that identifies you — a nickname works just as well.
Advertising
The Android and iOS apps are free and show a full-screen ad between runs, at most once a minute. The ads are served by Google AdMob. The web version shows no ads.
To serve and measure ads, and to prevent ad fraud, Google may collect information such as your device’s advertising identifier, IP address, device model and operating system, and how you interact with ads. Google processes this under its own privacy policy.
Your consent
If you are in the European Economic Area, the United Kingdom or Switzerland, the app asks for your consent, through Google’s consent form, before any ad is requested. If you decline personalised ads, Google may still show non-personalised ads, which rely on limited data such as general location from your IP address.
You can change your answer at any time by clearing the app’s data (or reinstalling it): the consent form will be shown again on the next launch.
Opting out of ad tracking
- Android: Settings → Privacy → Ads, then delete or reset your advertising ID.
- iOS: Settings → Privacy & Security → Tracking.

Why we are allowed to
Where the EU or UK General Data Protection Regulation applies, we rely on:
- Your consent for personalised advertising. You can withdraw it as described above.
- Performing the service you asked for when you save a score to the ranking.
- Our legitimate interest in keeping the game secure and the ranking honest (anonymous ID and App Check), in finding and fixing crashes (crash reports), and in funding the game with non-personalised ads.
How long it is kept
- Ranking entries stay on the board for as long as the ranking exists, or until you ask us to remove them.
- The anonymous player ID is kept while it is linked to a ranking entry. If you uninstall the game or clear its data, your device gets a new one and the old ID is no longer used.
- Settings on your device stay until you clear the app’s data, clear your browser’s site data, or uninstall the game.
- Crash reports are kept by Firebase Crashlytics for 90 days and then deleted.
- Advertising data is kept by Google according to its own retention policy.
Your rights
Depending on where you live, you may have the right to access, correct or delete the information we hold about you, to object to or restrict how it is used, and to receive a copy of it. California residents have similar rights under the CCPA, including the right to opt out of personalised advertising, which you can do with the device settings in section 03.
To remove your ranking entry, or for any other request, write to ask@giacomoto.dev. Because the game has no accounts, tell us the name, score and approximate date of the entry so we can find it.
If you are in the EU or UK and believe we have handled your data unlawfully, you can also complain to your local data protection authority.
Children
Numeris is not directed at children under 13, and we do not knowingly collect personal information from them. If you believe a child has submitted a ranking name that identifies them, contact us and we will remove it.
Security
All traffic between the game and Firebase is encrypted. The ranking only accepts entries from a genuine copy of the game, written by the player they belong to, and checked for shape before they are stored. No system is perfectly secure, but we keep what we hold to the minimum so that there is little to lose.
Changes to this policy
If the game starts keeping something new, this page will be updated and the date at the top will change. Significant changes will be announced in the app’s store listing or in the game itself.
