Nonogrammes does not collect any personal data. The app is a calm logic game (picross / hanjie / nonograms) that requires no account and never identifies the user. Your preferences (light/dark theme, display options) and your progress (solved puzzles, statistics, achievements) are stored exclusively on your device, in the app's local Hive database.
The app does not transmit any personal data to our servers or to third parties. No account, no cloud, no synchronization of your information. Nonogram puzzles are generated locally on the device, and this generation does not identify you and contains no personal information about you. The app works 100% offline.
You do not need to create an account to use Nonogrammes. We do not ask for an email, name, phone number, or any other identifying information.
The app contains no advertising, no advertising tracking SDKs, no advertising identifier (Advertising ID), no analytics (Google Analytics, Firebase Analytics, Mixpanel, etc.), and no user behavior measurement tools.
Your preferences and progress are stored locally on your device by the app (built with Flutter, local Hive storage, for Android). This data never leaves your phone.
The only system feature used by the app is share_plus, which opens your operating system's native share sheet when you explicitly initiate sharing a screenshot or text (for example, a solved puzzle). No sharing happens without your action, and the app has no access to any of the destinations you choose to share with.
You stay in full control of your data. Uninstalling the app permanently deletes all the data it has stored on your device.
Nonogrammes is designed for all ages (5+), including young children under 13. In accordance with the U.S. COPPA (Children's Online Privacy Protection Act) and the GDPR, we place particular importance on protecting children's privacy:
If you are a parent or guardian and have a question about your child's privacy, please contact us at the address below.
This policy may be updated if the app undergoes major changes. The last update date is shown at the top of this page.
