Pingolin Note

Pingolin Note is a notes app built so that nobody but you can read your notes. Everything you write is encrypted on your device before it is uploaded.

Keys are exchanged with X25519 and signed with Ed25519. Your password never leaves your device: sign-in uses SRP, so the server can verify you without ever receiving it. These are published, standard algorithms — nothing home-grown. Pingolin Note is made by Pingolin LLC.
