If you have forgotten your password, the only option is to erase the space and start fresh. You can do this in Settings → Erase Space (password required — if you have also forgotten this, Factory Reset is the only option).

Recommendation: Save your password in iOS Keychain (iCloud Keychain) to prevent forgetting it. Also back up regularly using the archive feature.

1. Download and install PP Album on your new device.
2. Enter your original password to unlock the corresponding space.
3. Go to Settings → iCloud Sync and confirm that sync is enabled.
4. The App will automatically download and decrypt your synced photos and videos from iCloud Drive.

Note: iCloud download time depends on network speed and file count.

In apps that support Share (Photos, Files, Safari, etc.), select the items you want, tap Share, then choose PP Album (or “Copy to PP Album”) from the share sheet.

Only the items you share in that action are written to the encrypted vault. The Share Extension does not access your entire photo library, and nothing is uploaded to developer servers.

This is by design. PP Album copies selected photos into the App's encrypted storage — the originals in your system photo library are not affected in any way.

If you want to remove the originals from your system library, please delete them manually from the Photos app.

1. Transfer the .ppa file to the target device via AirDrop, Files app, email, etc.
2. Find the file on the target device and tap "Open with PP Album" (or share it to PP Album from the Files app).
3. The App will open the archive import screen. Enter the archive password (if encrypted).
4. Select the files you want to import and complete the import.

On the unlock screen, simply enter the hidden space password directly in the password field. The system automatically recognizes and unlocks the corresponding hidden space — no special button or action required.

This design ensures that even if someone watches you unlock the app, they cannot detect the existence of a hidden space.

Go to Settings → Storage Space to view:

• Total media file usage
• Thumbnail cache size
• Per-space breakdown

On this page you can also clear the thumbnail cache to free up space (thumbnails are automatically regenerated when needed).

The App uses AES-256-GCM encryption (via iOS CryptoKit), with keys derived by PBKDF2-SHA256 (100,000 iterations) from your password.

You can verify this by browsing the App's sandbox directory in a file management tool — all media files are stored with a .enc extension and cannot be opened by any image or video viewer.

There are several options:

• Delete a single space: Settings → Erase Space → confirm with password.
• Factory Reset (delete everything): Settings → Developer Tools → Factory Reset. This permanently deletes all local data and iCloud synced data (irreversible).
• Uninstall the App: Deleting the App removes all local data. iCloud data may remain (clear it first in the App before uninstalling).

1. Restart the App and check if the issue persists.
2. Check if an iOS system update is available.
3. Check if a new version of PP Album is available on the App Store.
4. If the issue continues, contact us by email with: device model, iOS version, and the steps that led to the crash.

If you have enabled crash reporting in Settings, crash information will be submitted automatically to help us diagnose the problem.
