No. The challenge library, explanations, progress tracking, favourites, settings, and reminders all work offline. The Android app does not request internet permission.
No. There are no accounts or sign-in screens. You are never asked for a name, email address, or password inside the app.
Your answers, challenge history, streaks, favourites, reminder time, and settings are stored locally on your device. App backup is disabled, so this information is not uploaded to Android cloud backup by Mistake Hunter.
Use “Reset progress” in Settings to clear your history and streaks. To remove all remaining local data, including favourites and preferences, clear the app’s storage in Android settings or uninstall the app.
Notification permission is requested only if you enable the optional daily reminder on Android 13 or later. Reminder scheduling and delivery happen on your device.
No. Progress is kept only on the device, and Android cloud backup is disabled for the app. Uninstalling removes the local data, so it cannot be restored by ZUTORS.
No. Mistake Hunter is free and contains no advertising, subscriptions, in-app purchases, analytics, or tracking SDKs.
Mistake Hunter supports Android 7.0 (API 24) and newer Android versions.
Email the challenge title or visible case details, what you expected, and your app version if available. A screenshot can help, but remove any unrelated personal information before attaching it.
