Privacy Policy

Last updated: June 2026

Data collection

Tessera does not collect personal information. There is no account and no sign-up. Your progress — best times and which puzzles you've completed, per scene and difficulty — is stored only on your device.

Analytics

The app uses TelemetryDeck to send anonymous, aggregated product-interaction events — for example, "a level was started", "a level was won", or "onboarding was completed", along with non-identifying gameplay facts (difficulty, whether assists were on, how long the round took). This data helps me understand how the game is used and where it can be improved. These events contain no personal data, no advertising identifiers, and nothing that can be linked back to you.

Third-party services

TelemetryDeck (operated by Apparata GmbH in Berlin, Germany — GDPR-friendly) is the only third-party service the app contacts. It does not set cookies, does not track across apps, and does not build user profiles.

Network

The game itself runs entirely offline once installed. The only network activity is the anonymous analytics events described above.
