Privacy

Your data is yours

No account. No email, no password, nothing to sign up for.
End-to-end encrypted sync. Your documents are encrypted on your device with a key only you hold.
The server stores only ciphertext. It cannot read your notes, their titles or their paths.
Verifiable. How the encryption works is documented in detail, and the source code will be published so that anyone can check these claims.
