privacy

Last updated 14 November 2026

Short version: marcdown keeps your notes on your Mac. We do not collect them, read them or train anything on them.

The app

• Your notes stay in the folders you choose. marcdown sends no note content anywhere.
• marcdown has no analytics and no tracking.
• The app checks for updates by downloading a public update list from marcdown.app. That request contains your app version and macOS version, like any web request.
• Agent access (marc mcp) runs on your Mac and answers only the agents you connect. Showing agents what you are looking at is off until you turn it on.
• If you choose to share crash reports, they contain technical data about the crash, not your notes.

Buying encore

• Paddle.com handles the payment as our reseller and collects your name, email address, country and payment details. Paddle's privacy policy applies to that data.
• We receive your email address and the purchase details from Paddle so we can send your activation link and help you restore a purchase. Your licence file contains a hashed form of your email address, not the address itself.
• We send activation and restore emails through our email provider, Resend.
