Privacy Policy
Last updated 1 October 2026
This policy covers Zuzzle Numbers Game — the game published
under that name on Google Play and the App Store, playable in the browser on this site, and
installed on a device simply as Numbers (bundle identifier
com.mikepenz.numbers) — and this website at numbers.mikepenz.dev.
The game collects no data. There is no account, no sign-in, no remote analytics,
no advertising, no crash reporting and no tracking SDKs. The Android build does not
even declare the INTERNET permission, so it cannot send anything anywhere.
What stays on your device
Scores, statistics, streaks, daily results, unlocked modes and your settings are written to
ordinary app storage on the device you play on — a preferences file on Android, the app’s
own NSUserDefaults suite on iOS and macOS, and browser storage in the web version.
None of it is transmitted. Uninstalling the app, or clearing this site’s data in your
browser, deletes it.
Device backups
Android Auto Backup and Apple’s iCloud or encrypted device backup may copy that local file into your own cloud account, so a new device restores your progress. Whether this happens is a setting on your device, not something the game asks for, and the copy is held by Google or Apple under their terms — we cannot read it.
Notifications
The daily reminder is optional and off until you switch it on. It is scheduled locally by the operating system; there is no push server and no device token leaves the device.
This website
The site sets no cookies and runs no analytics. Three parties do see something when you load a page, and none of them are us:
- Cloudflare serves the site as a CDN and keeps edge logs (IP address, user agent, requested URL, timestamp) for security and operations — Cloudflare privacy policy.
- Uberspace hosts the files and keeps the usual web-server logs — Uberspace privacy policy.
- Google Fonts delivers the webfonts these pages use, which means your browser requests them from Google and Google sees the IP address that asked — Google privacy policy.
We do not store or have access to those providers’ logs. The game at play.html checks for updates when online; once cached, it can run offline.
The app stores
If you installed the game from a store, that store collects installation, device and crash information under its own policy, and reports aggregate figures to us as the developer. We never receive anything that identifies you. See Google Play and Apple.
Children
The game is suitable for all ages and collects no data from anyone, children included.
Your rights
We do not store personal data about your gameplay or have access to the provider logs described above. For questions about data connected to this website, contact us at [email protected]. For data held by Google or Apple through their stores, you can also contact them directly.
Changes
If this policy changes, the date at the top changes with it. Material changes will be noted in the app’s release notes.
