Frequently Asked Questions
Is my data secure?
Your diary entries are stored on your device, and we do not have a server copy that we can read or restore. Local storage does not mean that every app version encrypts every local copy. The published iOS version 1.0.30 uses an earlier format that is not encrypted by the app. Protect your device and see our Privacy Policy for details.
Can I backup my data?
The app does not provide its own cloud backup or a guaranteed way to restore entries on another device. Operating-system backups may behave differently depending on your settings; we have not verified every restore path. Do not uninstall the app to test a backup. Contact support before changing devices or deleting the app if your entries are important.
I forgot my PIN code. What can I do?
We cannot retrieve or reset your PIN remotely. Please do not uninstall or reinstall the app to try to reset it: doing so may permanently remove your diary, and it may not reliably clear protected PIN storage. Contact support for guidance without sending your PIN or diary contents. Recovery cannot be guaranteed.
How can I delete my data?
You can delete individual entries in the app. If you intentionally want to remove the app's local diary data, uninstalling the app may permanently remove it. Operating-system backups or protected storage may retain separate copies or settings, so uninstalling alone is not a guarantee that all copies are erased. Do not uninstall if you want to keep your entries.
