Your notes are none of our business.
An encrypted notes app that keeps everything on your device. No account, no cloud unless you ask for it, and a Mac app you buy once.
Everything you want from a notes app. Nothing that needs a server.
A real block editor with links, folders and tags, plus the things only a private app can offer.
Lock a note in one click.
Each locked note is encrypted with AES-256-GCM and a key derived from its password. Open it with Touch ID on Mac, Face ID on iPhone. Or lock the whole app and let it lock itself when you walk away.
Four themes, or match your Mac.
Light, Dark, Night, Terminal. Follows the system setting if you like.
Type [[ to link notes.
Wiki-style links with autocomplete, plus folders and tags.
Notes that delete themselves.
Set a timer from one hour to thirty days. When it runs out, the note is gone for good.
A second password for bad days.
A duress password opens decoy notes. Your real notes stay encrypted on disk.
Sync, if you want it. Encrypted before it leaves.
Turn on Dash Sync and your Mac, iPhone and iPad stay in step. Notes are encrypted on the device with a vault key the server never has. This is what our relay sees:
$4.99 / month · $47.99 / year · 7-day trial · optionalAI that stays on your Mac.
Summarize, rewrite and ask questions with Ollama or LM Studio. Nothing leaves the machine.
Touch ID on Mac and Face ID on iPhone unlock the app or any locked note; a password is always the fallback.

The details are the promise.
Every claim on this page is checkable in the source. We would rather show the algorithm than say “military-grade”.
