- AES-256-GCM encryption with PBKDF2 key derivation (600k iterations by default) - Supports text and file encryption (up to 256MB) - Data never leaves your device - Share encrypted content via QR code or link - No account, no server storage, no tracking

The crypto is handled by the Web Crypto API, and the source is straightforward if anyone wants to take a look. Would love feedback on the UX and any edge cases I might have missed.
