Napdoku Privacy Policy
Napdoku: Cat Sudoku Puzzle · Published by AppBurst · Package name: com.appburst.napdoku
Last updated: October 30, 2026
This policy covers the Napdoku app for Android, published by AppBurst ("we", "us"). The short version: Napdoku has no accounts, no ads, no analytics and no game server. The puzzles are made and played on your own device, and nothing about you or your games is sent to us.
1. Information we collect
We do not collect, receive or store any personal information through Napdoku. The app does not ask for your name, email address, contacts or location, and it does not send your activity anywhere. The whole game, including the puzzles and the hints, runs on your device and works without an internet connection.
2. Information stored on your device
To work, Napdoku saves the following in its own storage on your device:
- The puzzle in progress and the daily puzzle in progress, so you can continue later
- Your settings (sound, vibration, auto-cross, hearts, timer, which pets nap on the board) and your favourite pet
- Your progress and statistics, such as the levels solved, your fastest times and your daily streak
This information is not sent to us. If you have turned on Android's backup to your Google account, Android may include it in that backup so it can come back on a new phone; we have no access to those backups. You can delete everything by clearing the app's storage in your Android settings or by uninstalling the app.
3. Ratings and sharing
After you have solved some puzzles, Napdoku may ask Google Play to show its rating window. That window is part of Google Play: if you rate or review the app there, Google handles it under the Google Privacy Policy, and we only see what is published on Google Play. If you share your daily result, the text is handed to the Android share sheet and goes only to the app you pick.
4. Permissions
The app uses vibration for haptic feedback, which you can turn off in the app's settings. Its Android package includes network access, but gameplay does not send data over the network. When you tap an external link, such as this policy, it opens in your browser. The app does not request access to your contacts, photos, camera, microphone, location or notifications.
5. Third-party services
Napdoku contains no advertising, analytics or tracking software. The app is distributed through Google Play, which may collect information about installs and crashes under the Google Privacy Policy. This website is hosted by Cloudflare, which processes technical data such as IP addresses to deliver the pages; see this website's privacy policy.
6. Children
Napdoku is not directed at children under 13, and it does not collect personal information from anyone. If you believe a child has sent us personal information by email, contact us and we will delete it.
7. Your rights
Because we hold no personal data from Napdoku, there is nothing for us to access, correct, export or delete on your behalf; you control everything on your own device. If you contact us by email we will use your address only to reply, and you can ask us to delete that correspondence at any time.
8. Changes to this policy
If Napdoku changes in a way that affects this policy (for example, if a future version shows ads), we will update this page and the date at the top before the change reaches you.
