App name: Tessera Package name: com.kirsulab.tessera Publisher: KirsuLab LLC Contact: hello@kirsulab.com

This Privacy Policy describes how KirsuLab LLC ("we", "us") handles information in connection with the mobile game Tessera (the "App"), available on Google Play and the Apple App Store.

1. Information We Collect

The App does not require an account, and your game progress and settings are stored only on your device. We do not operate our own servers and do not collect or store your personal information ourselves. However, the App uses third-party services from Google — Google AdMob (advertising) and Google Firebase (analytics and crash reporting) — which automatically collect certain data from your device, as described in Sections 2 and 3.

2. Advertising

The App displays banner advertisements served by Google AdMob, a service of Google LLC. To serve and measure ads, Google may automatically collect certain data from your device, including:

Advertising identifiers (Android Advertising ID / Apple IDFA, where permitted)
IP address and coarse location derived from it
Device information (model, operating system, language, screen size)
App interaction data related to ad performance (e.g., ad views and clicks)

This data is collected and processed by Google under its own policies:

3. Analytics and Crash Reporting

The App also uses Google Firebase services provided by Google LLC:

Firebase Analytics — collects aggregate, non-identifying usage data such as app opens, screens viewed, gameplay events (e.g., a game started or completed), session length, and general device information (model, operating system, language, and region derived from IP address).
Firebase Crashlytics — collects crash and diagnostic data (crash stack traces, app version, device model, operating system, and device state at the time of a crash) so we can fix problems.

This data is used in aggregate to improve the App and is not used to identify you personally. Data collected through Firebase is processed by Google under the policies above and under Firebase Privacy and Security.

4. Consent and Your Choices

Where required by law (for example, in the European Economic Area, the United Kingdom, and Switzerland under the GDPR, or in certain US states), the App shows a consent dialog before any ads are requested. You can choose whether to allow personalized advertising; if you decline, ads may still be shown but will not be personalized.

On Android, you can reset or delete your Advertising ID in Settings → Privacy → Ads.
On iOS, you can control tracking permission in Settings → Privacy & Security → Tracking.

5. Children

The App is a general-audience puzzle game and is not directed at children under 13. We do not knowingly collect personal information from children. If you believe a child has provided personal data through the App, please contact us and we will assist in addressing the issue.

6. Permissions Used by the App

Internet access — required to load advertisements and to send analytics and crash reports.
Vibration — used for haptic feedback during gameplay.

The App does not request access to your camera, microphone, contacts, precise location, or files.

7. Data Retention and Security

Since we do not collect personal data ourselves, we do not retain any. Data collected by Google AdMob and Google Firebase is retained and secured according to Google's policies linked above.

8. Changes to This Policy

We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated effective date. Continued use of the App after changes means you accept the updated policy.
