Infinite Puzzle Studio ("we", "us", or "our") makes the game Hashi (the "App"). This policy explains what data the App collects, why, who we share it with, and how you can control or delete it.
1. No account, progress stays on your device
Hashi has no sign-up or account. Your game progress, coins, settings and the player name you choose are stored only on your device. The tournament rivals are simulated players, so your name is never sent to other players or to our servers. Deleting the App deletes this data.
2. Data collected by third-party services
The App uses the following services. They may collect data as described below and process it under their own privacy policies.
- Google Firebase Analytics: anonymous usage data (for example levels played, screens opened, purchases started), an app instance identifier, device model, OS version, language and coarse location derived from the IP address. We use it to improve the game. Firebase privacy
- Google Firebase Crashlytics: crash reports and diagnostics (stack traces, device state, the screen you were on) so we can fix bugs.
- Google AdMob: shows ads. AdMob may collect device identifiers, IP address, ad interactions and diagnostics. The advertising identifier (IDFA) is only used if you allow tracking in Apple's App Tracking Transparency prompt. In the EEA, UK and Switzerland we ask for your consent with Google's consent form first. How Google uses data
- RevenueCat: processes in-app purchases. It receives an anonymous app user ID and your purchase history from Apple or Google so purchases can be restored. RevenueCat privacy
- Apple App Store / Google Play: handle payments. We never see your payment details.
We do not sell your personal data. We do not collect your name, email, contacts, photos or precise location.
3. Tracking and your choices
- On iOS you can allow or deny tracking in the App Tracking Transparency prompt, and change it any time in iOS Settings > Privacy & Security > Tracking.
- In the App, Settings > Privacy choices lets you review or withdraw your ad consent.
- Buying "Remove Ads" or the Starter Pack turns off interstitial ads.
4. Retention and deletion
Analytics data is kept for up to 14 months, crash reports for up to 90 days. Because we have no account, we cannot link this data to you by name. To ask us to delete data linked to your device, email us with the App's name and we will forward the request to the services above. Deleting the App removes all data stored on your device.
5. Children
Hashi is a general-audience game and is not directed at children under 13. We do not knowingly collect personal data from children. If you believe a child has given us data, contact us and we will delete it.
6. Security
Data sent to the services above is encrypted in transit. No method of storage or transmission is 100% secure, but we use commercially reasonable means to protect it.
7. Changes to this policy
We may update this policy. Changes take effect when they are posted on this page, with a new "Last updated" date.
