Is it free to use?
Logging, private notes, and graphs (past 30 days) are free to use. PDF export, CSV export, full-history graphs, iCloud backup, and App Lock are unlocked with a one-time purchase (no subscription).
I want to restore my purchase
Tap the "Settings" tab → "Restore Purchases". If you're signed in with the same Apple ID, it can be restored.
Where is my data stored?
Everything is stored only on your iPhone. There is no transmission or collection of data to external servers, and no account registration is required.
What is iCloud backup?
The premium iCloud backup feature automatically backs up your data to Apple's private database. It can be used for accessing data on other devices or migrating data when switching phones. It is never shared with family or others.
I can't export a PDF
PDF export is a premium feature. Please purchase it from "Settings" → "Unlock Premium". If you've already purchased it, try "Restore Purchases".
How do I unlock App Lock?
App Lock can be unlocked with Face ID / Touch ID authentication. In environments where biometric authentication isn't available, the lock is automatically released. You can toggle it on/off from "Settings" → "App Lock".
I accidentally deleted a record
Deleted records cannot be undone. If you have iCloud backup (premium) enabled, you can restore your data when switching devices, etc.
