SECURITY DETAILS

Your encryption keys are stored in Android's hardware-backed KeyStore, making your files virtually impossible to decrypt without your device. Even if someone extracts the encrypted files, they cannot be opened without the secure keys that never leave your phone.

All content is encrypted with AES-256-CBC encryption - the same standard used by governments and banks worldwide. Files are stored in your app's private directory, protected by both Android's app sandbox and strong encryption.

WHO IS THIS FOR?

Perfect for anyone who wants to keep sensitive content private - whether it's personal photos, private notes, financial documents, medical records, or anything else you don't want accessible to others.

IMPORTANT: Because encryption keys are tied to your device's hardware, encrypted files cannot be decrypted on other devices. This is a security feature. Use the export function to decrypt files when needed.

Vault requires Android 5.1+ and a device with biometric authentication support.
