Zero-knowledge notes, tasks, files, passwords and journal secured by a single 12-word recovery phrase, with no email or password required. All content is encrypted client-side (XChaCha20-Poly1305) before it leaves the device, and the cryptographic core and database schema are published on GitHub for audit. Currently web-based, with native apps in the works. It supports ‘Share & Burn After Reading’ Notes and is therefore listed in the Pastebin category, too.

This is the zero-knowledge notes app we wanted to exist, so we built it. There’s no email and no password, which means no account to breach: a single 12-word recovery phrase unlocks everything, and every note is encrypted client-side with XChaCha20-Poly1305 before it ever reaches a server. The crypto core and database schema are published, so the privacy claims are yours to inspect rather than take on faith. The recovery phrase puts you in full control, you hold the only key. Pick it if you want notes, tasks, and a journal that genuinely no one but you can read.
Measures the security configuration of the tool's own website, not the privacy of the product itself. A strong tool can still score low here.
