Privacy Policy
Tessera: Number Rush · Effective October 23, 2026 · Updated October 25, 2026
In short: Tessera does not collect, share, or sell any information about you. There are no accounts, ads, analytics, or tracking. Your scores and settings stay on your device.
Information we collect
None. Tessera: Number Rush (“Tessera”, “the app”) does not collect any personal information or usage data, and it does not send any data off your device. The app does not connect to the internet.
Information stored on your device
To work, the app saves a small amount of information locally on your iPhone or iPad:
- Your settings: haptics on or off, chosen grid size, and color theme.
- Your high scores: finish times and the date of each run.
- Your stats: number of games played and total time per grid size.
This information never leaves your device through the app, and we cannot see it. You can erase scores and stats at any time with High Scores ▸ Clear All, and deleting the app removes everything it stored.
Like other app data, this information may be included in backups of your device (for example, iCloud Backup), which are managed by Apple according to your device settings and Apple's privacy policy.
Tracking, advertising, and third parties
Tessera contains no advertising, no analytics or crash-reporting services, and no third-party code that collects data. It does not track you across apps or websites.
If you choose to share crash reports or diagnostics with developers in your device settings, Apple may provide them to us in anonymized form, as described in Apple's privacy policy.
Children
Because Tessera collects no information from anyone, it collects no information from children.
