What encryption algorithm is used to protect my PDF?

We utilize authenticated AES-GCM-256 with 100,000 PBKDF2 key derivation rounds using the browser's hardware-accelerated Web Cryptography API.

Can I restrict copying and printing permissions?

Yes. You can enforce granular security policies disallowing printing, text clipboard copying, or document annotations.

Is my master password sent to any server?

No. Key derivation and ciphertext compilation happen strictly in client RAM. Your password is never stored or transmitted.
