Frequently asked questions
Where are my entries stored?
Everything is stored only on your phone. There are no accounts and nothing is sent to our servers, so please make a backup before deleting the App or changing phones.
How do I move to a new phone?
On your old phone, tap ⚙️ → Contents → Backup & restore and save a backup file to iCloud Drive or Google Drive. Install the App on your new phone, open the same screen and choose "Restore from backup file".
I forgot my PIN.
PINs are stored as verification hashes, not the original digits, so we cannot retrieve or reset them. The lock restricts access to app screens; it does not encrypt diary or photo files. Consider reinstalling and restoring only if you have a valid backup. Records made after that backup cannot be recovered, so do not delete the app without a backup.
My font doesn't change right away.
Handwriting fonts download once on first use. Please stay connected to the internet and wait a moment.
I can't save a video to Photos.
Allow Haru Diary to add to Photos in your device settings, then try again.
How do I change the App's language?
Tap ⚙️ → Contents → Language to pick one of 20 languages or follow your device language.
Where can I check purchases or request a refund?
Check the price and purchase history in the App Store or Google Play store where you purchased the app. Submit refund requests through that store; approval is subject to its policies. Do not include payment card details or passwords in support emails.
Do I need to delete an account?
The app has no sign-up or server account. You can delete records inside the app, and delete separately saved backup files from their storage locations.
