Privacy Policy
Thousand, the card game for Android on Google Play (ru.rh1.thousand)
In short
- There is no account and no sign-in. The game has no advertising, analytics or tracking.
- Your games, scores and settings stay on your device.
- The only data the app sends is a Google Play purchase record, when you bought the full version, so that our server can confirm the purchase is genuine.
1. Who we are
The app is developed and published by Mikhail Matveev, an individual developer in Russia (“we”). Questions about this policy and your data: support@rh1.tech.
2. Data that stays on your device
Games in progress, scores, statistics, settings and the player names you type in are stored only on your device. They are never sent to us or to anyone else.
To remember that the full version is unlocked, the app derives a value from your device’s Android ID (and, on older versions of Android, its serial number) and stores it on the device. It is not sent anywhere.
3. Purchases
The full version is no longer sold. If you bought it earlier through Google Play, the app confirms the purchase when it starts, until the full version is unlocked on your device.
Payment was handled entirely by Google Play; we never see your card or payment details. Google Play gives the app a record of the purchase, signed by Google: the order number, the product, the purchase time and state, the purchase token and the app’s package name. The app sends this record and Google’s signature to our verification server, which checks the signature and answers whether the purchase is genuine.
The server does not store the purchase record. Like any web server, it records the technical details of each request in its logs: the IP address, the time, the address requested and the response status. These logs are used only for security and troubleshooting, and are deleted routinely.
The verification server is in St Petersburg, Russia. Versions of the app released before 1.70 reach it through an intermediate server of ours in France, over the network of Cloudflare, Inc.; that server passes the request on and does not store the purchase record.
Google’s own handling of purchases is described in Google’s privacy policy.
4. Pages the app opens
The app can open our websites in your browser: the new version of the game, our other games and the rules. They open only when you tap them, and the app sends nothing to them by itself.
5. Permissions
- Internet: to confirm a purchase, as described above.
- Google Play billing: to read your purchase from Google Play.
- Vibration: for feedback when you tap.
6. What we do not collect
The app does not access your location, contacts, camera, microphone, photos or files, phone number, accounts or advertising ID. It contains no advertising, analytics or crash-reporting code.
7. Sharing
We do not sell personal data or share it for advertising. We disclose it only where the law requires us to.
8. Children
The game is suitable for all ages. Apart from the purchase check described above, the app sends no data at all, and we do not knowingly collect personal data from children.
9. Security
All connections between the app and our servers are encrypted (HTTPS).
10. Your choices and rights
You can delete everything the app stores on your device by clearing the app’s data or uninstalling it.
You can ask what data about you we hold, and ask us to correct or delete it, by writing to support@rh1.tech. We reply within 10 working days.
11. Changes
When this policy changes, the new version is published at this address with a new effective date.
