Questions

How it works
  1. Set a PIN. Add your fingerprint too, and save your recovery code.
  2. Pick a reminder time. Log your mood straight from the notification.
  3. Write when you want to. Add a few words, a photo or a prompt answer to any day.
Can anyone read my diary?

Moodwren opens only with your PIN or fingerprint. There is no account and your entries are never sent to us.

What if I lose my phone?

Make a backup file in Settings, protected by a password you choose, and keep it on Google Drive or your computer. Backups are free.

What if I forget my PIN?

Use the recovery code shown when you set up the app to choose a new PIN.

Privacy at a glance
Diary entries and moods
Your entries, moods, tags, photos and settings are saved in the app on your phone. Photos you add are copied into the app's own storage.
PIN and fingerprint
Your PIN is stored only as a salted hash. Fingerprint checks are done by Android; the app never receives your fingerprint.
Backup files
A backup file is created only when you ask for it, encrypted with a password you choose, and saved where you pick with the Android file picker. We never receive it.
Purchases
Handled by Google Play; we never see your payment details.

Permissions: Notifications, for the daily reminder with mood buttons and the optional backup reminder. Biometric, to unlock with your fingerprint or face if you turn it on. Photos are chosen with the Android photo picker and backups are saved with the Android file picker, so no storage, camera, location, microphone or contacts permission is needed. Google's ad and purchase libraries add the advertising ID, network state and billing permissions. Internet is used for ads, purchases, crash reports, usage statistics and the settings file described above, never for your diary.
