The home page title has the word zero knowledge, I guess?

Their GitHub has slightly more info regarding this, but I agree that stuff like this should have at least a page dedicated for it that explains how they've implemented their security.

> Notesnook is a free (as in speech) & open-source note-taking app focused on user privacy & ease of use. To ensure zero knowledge principles, Notesnook encrypts everything on your device using XChaCha20-Poly1305 & Argon2.

As long as we’re walking down this road, you also don’t encrypt with Argon2. It’s a hashing function, specialized for passwords.

And chacha20-poly1305 is listed in the SSH MiTM issue.

Wireguard also uses ChaCha20-Poly1305, but I am not sure it's relevant? I believe that attack is specific to SSH:

"The attack exploits weaknesses in the specification of SSH paired with widespread algorithms, namely ChaCha20-Poly1305 and CBC-EtM, to remove an arbitrary number of protected messages at the beginning of the secure channel, thus breaking integrity."
