Privacy Policy for Math Streak

App name: Math Streak Package name: com.kirsulab.mathstreak Publisher: KirsuLab LLC Contact: hello@kirsulab.com

This policy explains what information the Math Streak mobile application (the "App") handles, how it is used, and the choices you have. We designed Math Streak to work without accounts and to collect as little data as possible.

1. Information we do not collect

• The App has no sign-up or login — we never ask for your name, email address, phone number, or contacts.
• Your game progress (scores, streaks, achievements) is stored locally on your device only and is deleted when you uninstall the App.
• We do not collect your precise location.

2. Information collected automatically

The App includes third-party software development kits (SDKs) provided by Google that automatically collect limited technical data needed for analytics, stability, and advertising:

• Google AdMob (advertising) — advertising identifier (Android Advertising ID), IP address, coarse device information, and ad interaction data, used to serve and measure ads. Learn more
• Firebase Analytics — pseudonymous app-instance identifiers and usage events (e.g. screens viewed, games played), used to understand aggregate app usage. Learn more
• Firebase Crashlytics — crash logs and device state at the moment of a crash (device model, OS version, stack trace), used to find and fix bugs. Learn more

3. How we use this information

• To keep the App stable and fix crashes.
• To understand, in aggregate, how the App is used and improve it.
• To show ads, which keep the App free.

We do not sell your personal information and do not use it for any purpose beyond the ones listed above.

4. Sharing

The data described in section 2 is processed by Google LLC as our service provider, under its own privacy commitments. We do not share data with any other third parties, except where required by law.

5. Advertising and your choices

• In the European Economic Area and the UK, the App shows a consent dialog (Google User Messaging Platform) before serving personalized ads. You can decline personalized ads and will see non-personalized ads instead.
• You can reset or delete your Android Advertising ID at any time in your device settings: Settings → Privacy → Ads.
• You can opt out of personalized ads in your Google settings: adssettings.google.com.

6. Children

The App is not directed at children under 13, and we do not knowingly collect personal information from children. If you believe a child has provided personal information through the App, contact us and we will help address it.

7. Data retention

Analytics and crash data are retained by Google on our behalf for limited periods (typically 90 days to 14 months depending on the data type) and then deleted or aggregated. Local game data stays on your device until you clear the App's data or uninstall it.

8. Security

Data collected by the SDKs above is encrypted in transit using industry-standard protocols (HTTPS/TLS).

9. International transfers

Google may process the data described above on servers located outside your country, including in the United States, under appropriate safeguards.

10. Changes to this policy

We may update this policy as the App evolves. Material changes will be reflected on this page with an updated effective date.
