Numbra is a number puzzle game published by Pixerion. We do not ask you to create an account, and we do not collect your name, email address or account profile.
Your saved game progress stays on your device. Advertising services may process device and interaction data. If you choose to enable analytics, Google Analytics for Firebase also receives pseudonymous app usage events.
Numbra saves the following locally so the game remembers where you left off. These saved files are not uploaded; selected usage events may be measured separately when you allow analytics:
Uninstalling the app deletes all of it permanently.
On first launch, Numbra asks whether you want to allow usage analytics. The choice is optional and can be changed in Settings → Usage analytics. Analytics collection is disabled until you explicitly allow it. Declining analytics does not restrict gameplay or rewards.
If enabled, Google Analytics for Firebase measures screens visited, level starts, completions and exits, solve duration, wrong-answer counts, hint use, newly unlocked achievements and ad impressions, clicks, rewards and SDK-reported revenue. Google also processes a generated app-instance identifier, device/app version and language, session activity and approximate location derived from network information. We use these reports to understand difficult puzzles, improve the game and evaluate ad placements.
We do not send your name, email, answer text, account profile or saved game files to Analytics. Analytics advertising ID collection and advertising personalization are disabled. AdMob advertising consent is a separate choice.
Turning analytics off stops future collection and resets the local Analytics identifier and data. Previously transmitted data is subject to Google's retention and deletion controls; changing the switch does not automatically erase historical server reports.
Numbra is free and supported by ads served through Google AdMob. To show ads and measure their performance, Google may collect and process:
| Data | Purpose |
|---|---|
| Advertising ID | Selecting ads and limiting how often the same ad is shown |
| Device and app information | Device model, operating system version, app version, language |
| Approximate location | Derived from IP address, at country or region level only |
| Ad interactions | Impressions, clicks, rewarded ad completions |
| App interactions and diagnostics | Advertising-related interaction events, crash reports, performance information and other diagnostics used to maintain and improve the advertising services |
This data is handled by Google under its own privacy policy: How Google uses information from sites or apps that use our services. Pixerion does not receive this data in an identifiable form — we only see aggregate revenue and performance reports.
Ads appear on the main menu, between levels, and when you choose to watch a rewarded ad for hint tokens or a level skip. Rewarded ads are always optional. Ads are never shown while you are solving a puzzle.
If you are in the European Economic Area, the United Kingdom, or Switzerland, Numbra shows a consent form on first launch where you decide whether personalised ads are allowed. You can change that decision at any time from Settings → Privacy options inside the game.
Wherever you are, you can reset or delete your advertising ID from your device settings: Settings → Google → Ads on most Android devices. Declining personalised ads does not restrict any part of the game — the ads you see simply become less relevant.
On iPhone and iPad, you can manage tracking permission in Settings → Privacy & Security → Tracking. Numbra requests Apple's tracking permission before allowing advertising tracking. You can decline tracking and continue playing. Google determines which ads may be requested based on the applicable consent choices and device permissions.
On Android, Numbra uses INTERNET and
ACCESS_NETWORK_STATE so ads and optional analytics can work. On iPhone and iPad, Numbra
may ask for permission to track activity for advertising through Apple's
App Tracking Transparency prompt. The game itself works fully offline.
Numbra does not access your camera,
microphone, contacts, photos, files, or precise location.
Numbra is a general-audience puzzle game. It is not directed at children under 13, and we do not knowingly collect personal information from them. If you believe a child has provided personal information through the app, contact us and we will address it promptly.
Saved progress remains on your device. Optional analytics events are held by Google in our Firebase/Analytics project, where we can review usage reports. Advertising data is held by Google AdMob. These services apply their own security safeguards and the applicable retention settings and policies.
Numbra has no player account. You can delete saved game data on your device and stop future analytics collection from the app. Remote analytics and advertising data are handled separately as described below.
Delete your game data from inside the app
This permanently deletes your completed levels, stars, hint tokens, daily puzzle results, streak and achievements. Your preferences, including analytics consent, are retained. It cannot be undone, and does not automatically delete data already held by Google.
Delete everything
Uninstalling Numbra removes the app and every file it created, including the locally saved game data. Google may retain previously transmitted analytics or advertising data under its policies.
Analytics data
Disable Settings → Usage analytics to stop future collection and reset local Analytics data. For a request concerning previously transmitted analytics data, contact us using the address below. We may need information sufficient to locate the pseudonymous installation record; we do not maintain an email-to-player profile.
Advertising data
Data collected by Google AdMob for advertising is held by Google, not by Pixerion, so we cannot delete it on your behalf. You can reset or delete your advertising ID from your device settings — on most Android devices, Settings → Google → Ads. Google's own retention policies then apply.
On iPhone and iPad, withdraw tracking permission in Settings → Privacy & Security → Tracking. To manage or request deletion of data retained by Google, use the controls and contact information in Google's privacy policy.
Ask us instead
If you would prefer that we handle a deletion request, email pixerion.dev@gmail.com with the subject line Data deletion request. We will explain the local deletion steps and review whether we can identify and address any applicable pseudonymous analytics record. We answer within 30 days.
If this policy changes, the updated version will be published at this address with a new "Last updated" date. Significant changes will also be noted in the app's release notes on Google Play or the App Store.
