Most ERPs protect data in transit and trust the server with the rest. LetterSheets encrypts your most sensitive records in your browser and keeps the keys with you.
Employee PII, payroll figures, and financial records are encrypted client-side. The server stores ciphertext it cannot read — a breach exposes nothing usable.
Key exchange and signatures use NIST post-quantum standards, so data captured today can't be decrypted by future quantum machines.
ML-KEM-768 · ML-DSA-65Each company gets a downloadable recovery key at setup. Access is unlockable only by you — no silent backdoor, no vendor master key.
Encryption isn't a setting you switch on — it's how the platform works from the moment you create a company.
Spin up an encrypted workspace and download your recovery key — the only path back into your data.
Your password derives the key that decrypts sensitive fields, right in the browser. The server never sees it.
Records encrypt and decrypt transparently as you use the app — nothing to manage, nothing exposed.
Bring HR, accounting, inventory, and the rest onto one private, quantum-safe platform.
