FAQ

Are my files encrypted?

Yes. All files stored in the vault are encrypted using AES-256-GCM encryption with unique per-file keys. Your password is hashed with PBKDF2-SHA256 (100,000 iterations). We cannot access your files or password.

How do I unlock the vault?

Enter your PIN on the lock screen to unlock. You can also enable Face ID / Touch ID for faster access.

I forgot my password. How do I recover it?

Tap "Forgot Password?" on the lock screen to access password recovery. You will need to answer the security question you set during initial setup.

Does the app upload my photos or videos?

Calculator+ Photo Vault stores all files locally and encrypted on your device. The only exception is the optional iCloud Backup feature (Pro), which backs up encrypted data to your personal iCloud account.

How do I report a bug?

Please email us and include the steps to reproduce the issue, a screenshot or screen recording, your device model, and iOS version.
