Your data is yours
Markdown Mate is designed with a local-first philosophy. We believe your notes are private and should remain under your control.
No data collection
We do not collect, store, or transmit any of your personal information or the content of your notes. Markdown Mate does not have backend servers, accounts, or tracking systems.
Local storage
All your notes are stored directly on your computer's file system as standard Markdown (.md) files. Markdown Mate only accesses the folders you explicitly grant it permission to open.
No analytics or tracking
The app does not include analytics, crash reporting, or third-party tracking scripts. Your usage of the app is entirely private.
App sandboxing
Markdown Mate uses macOS sandboxing technology. This ensures the app can only access the specific files and folders you choose, providing an additional system-level layer of security.
