1. On the lock screen, tap “Forgot PIN?”.
2. Answer the security question you chose when you set up the lock.
3. Set a new PIN or pattern. Your diary stays intact.

For your privacy we never store your PIN or security answer and cannot unlock the App for you. If you have also forgotten the answer, the only option is to reinstall the App and restore from a backup.

1. Install Lumi Diary and open Settings → Backup & Restore.
2. Choose Google Drive (Android) or iCloud (iPhone) and sign in with the same account you backed up with — or choose “Import ZIP file”.
3. Pick the backup and tap Restore. Keep the App open until it finishes.

1. Sign in with the same Google Play account / Apple ID you used to buy.
2. Open Settings → Premium and tap “Restore purchases”.
3. Still missing? Email us with your order number (GPA.… or Apple order ID).

1. Android: Google Play → profile icon → Payments & subscriptions → Subscriptions → Lumi Diary → Cancel subscription.
2. iPhone: Settings → [your name] → Subscriptions → Lumi Diary → Cancel Subscription.
3. Cancel at least 24 hours before the current period ends. Uninstalling the App does NOT cancel a subscription.

Payments are processed by Google Play or Apple, so refund requests go through the store: Google Play (play.google.com → Order history) or Apple (reportaproblem.apple.com).
