Your files stay yours

Notes and LaTeX projects are plain files in a folder you pick, not rows in someone else's database.

Works with no connection

Write on a plane. Changes queue up and merge the moment you are online again.

One account, every device

The same workspace on desktop, phone and the web — with conflicts you resolve, never silently lose.

Questions people ask

Why does macOS say the developer cannot be verified?

The macOS builds are not notarised yet. Open the app once with right-click → Open, or allow it from System Settings → Privacy & Security. We are working through Apple's developer programme; this notice will go away once the builds are signed.

Why does Android warn me before installing the APK?

Android blocks installs from outside the Play Store until you allow them. When the warning appears, tap Settings, turn on installs from this source for your browser, then reopen the downloaded file. Compare the SHA-256 on the card with the file you downloaded if you want to be certain nothing changed in transit.

Does the app update itself?

Not yet. Come back to this page for a new build — the version on every card is always the latest one we have published.

How do I uninstall it?

Delete the application the way you would any other on your platform. Your vault folder is untouched by uninstalling: your notes are plain files and stay exactly where they are.
