Where is my data stored?

Notes are stored as Markdown files in a workspace folder chosen by the user. Core note-taking works offline and Octarine does not upload note content to its servers.

We don't want to even know what you write, just like we wouldn't want you to know what we write.

What OS versions does Octarine support?

macOS 13+, Windows 10/11, and Linux (tested on Ubuntu and Fedora). If you run into issues on another distro, please report it in the issue tracker.

Can I use Octarine on my phone?

An iOS beta is available to eligible Octarine Pro users through TestFlight. There is no public App Store release yet.

How do I sync or back up my notes?

Octarine stores notes as plain markdown files, so you can sync them with any service that syncs files — iCloud, Dropbox, OneDrive, Google Drive, Syncthing, or anything similar. There's also a built-in Git sync feature for one-click backups to GitHub or GitLab. You choose what works for you — no vendor lock-in.

Is Octarine offline-first?

Yes. All your data is stored locally, so Octarine works fully offline. The only exception is externally-linked images, which need a connection to load.

I see a few API calls in the app. What are they for?

There's 3 API calls in the app.

  • Check if there's any new update available (runs on startup or every 12 hours the app has been open).
  • Send a notification upon installation to the server (bumps up the count, no device information is sent).
  • Fetch the latest changelog from the server to display in the app.

Network access is used for update and changelog checks, an anonymous install count, license activation, user-requested public sharing, and optional AI providers. The marketing website uses Pirsch analytics.

Is Octarine "open source"?

No, there are no plans to open-source Octarine at this time.
