Privacy Policy

Updated October 25, 2026

Markus does not collect, store or share any personal data. It has no accounts, no analytics, no advertising and no tracking.

Your documents

Markus reads only the folders and files you open. They stay on your Mac; Markus never uploads them anywhere.

Apple Intelligence

Summaries, answers and explanations are produced on your Mac by Apple's on-device model. Nothing is sent to us or to any third party.

Network access

Markus connects to the internet only to:

• load images that a document you open links to;
• reach GitHub (api.github.com, raw.githubusercontent.com) when you open a remote repository or check your GitHub request limit in Settings.

A GitHub token you enter is kept in your Mac's Keychain and sent only to GitHub.

Settings

Your app settings — appearance, accent color, text size and the like — sync between your Macs through your own iCloud account. We have no access to them.

Changes

If this policy changes, the new version will be posted on this page with a new date.
