Privacy Policy

Last updated: 23 December 2025

In one line

This app collects no personal data. There is no account and no sign-in, and everything you write stays on your own Mac.

What is not collected

• No user accounts and no sign-in
• Document contents are never sent to a server
• No analytics and no tracking
• No advertising

Where documents are stored

Every markdown file you write or edit is stored on your device only. Nothing is passed to the developer or to any third party.

When the network is used

Only in these two cases.

• PlantUML diagrams — the diagram code is sent to a rendering service to produce the image. It carries no personal data.
• In-app purchase — buying the Quick Look preview goes through Apple's StoreKit. Apple handles payment; the developer never receives card details.

Otherwise the app works entirely offline.

Third parties

Since no personal data is collected, none is shared.

Children

No personal data is collected from any user, and therefore none from children.
