Frequently Asked Questions
How secure is this?▼
It uses AES-256-GCM which is the same encryption standard used by governments and banks. Combined with PBKDF2 key derivation using 100,000 iterations, it is extremely secure.
Can I recover data without the password?▼
No. The encryption is password-based. Without the exact password, the data cannot be decrypted.
Is my data sent anywhere?▼
No. All encryption and decryption happens in your browser using the Web Crypto API. Nothing is uploaded to any server.
