YOUR PRIVACY COMES FIRST
Your keys stay yours.
Encryption keys are derived on your device and are never uploaded. QuickMath does not store your private media or encryption keys on developer-operated media servers.

Your secret. Your privacy.
Choose a PIN you can remember. If you lose your PIN or required recovery credentials, your encrypted data may not be recoverable. Shorter PINs provide less protection against offline guessing attacks.
