This Privacy Policy describes how the Nonogram app ("the App", "we", "us") handles information when you use it.
The App does not require an account and does not collect or transmit personal information to our own servers. All data you create in the App - your puzzles in progress, solved pictures and best times, daily puzzle records and streaks, hint usage, and settings - is stored locally on your device only.
The App uses the third-party services described below (Google AdMob and Firebase Crashlytics), which collect limited device and usage information directly.
The App displays banner ads and optional rewarded ads served by Google AdMob. To serve ads, Google AdMob and its partners may collect and use device identifiers (such as the advertising ID), IP address, and other technical information, and may use this information to show personalized or non-personalized ads. This data collection is governed by Google's own privacy policy, available at https://policies.google.com/privacy. You can control ad personalization in your device's settings (e.g., Settings > Privacy > Ads on Android).
The App uses Firebase Crashlytics, a service provided by Google, to receive reports when the App crashes so we can fix problems. A crash report contains technical information such as the device model, operating system version, app version, the state of the App at the time of the crash, and a randomly generated installation identifier. Crash reports do not include your name, email address, or the content of your puzzles, and they are used only to diagnose and fix problems. Firebase's data handling is described at https://firebase.google.com/support/privacy.
The App requests internet access solely to load and display ads. If you turn on the daily puzzle reminder, the App asks for permission to show notifications and re-registers the reminder after the device restarts. It may use vibration for game feedback, which you can turn off in Settings. It does not request access to your contacts, location, camera, microphone, or storage.
The App may invite you to rate it using Google Play's in-app review feature. Any rating or review you submit is handled by Google Play under Google's privacy policy; the App never sees what you write.
We do not sell your personal information. We do not share it with third parties, other than the advertising data described in Section 2 and the crash reports described in Section 3, which are collected directly by Google (AdMob and Firebase), not by us.
The App is not directed at children under 13, and we do not knowingly collect personal information from children under 13.
Since all data is stored locally on your device, you can delete it at any time with Settings > Reset all data in the App, by clearing the App's data, or by uninstalling the App. See also our Data Deletion page.
We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated "Last updated" date.
