Private by design

Only you hold the keys to your data.

Sensitive data stays encrypted at rest. No PII is stored, not even your email address.

01 User device holds only key
02 Encrypted data protected at rest
03 ONE cannot read it

Anonymous age verification

Verify once. Prove your age anywhere.

User-held encryption keys unlock reusable, one-tap age verification without exposing PII.

Passkey first

Skip the password. Skip the inbox.

Passwords can be guessed or phished. Email login flows are slow and vulnerable to phishing. Passkeys are fast and phishing-resistant.

Password Phishable
Email login Slow + phishable
Passkey Fast + phishing-resistant
