Privacy

ContextMate the software (the CLI, the sync engine, the MCP server) collects no telemetry, no analytics, and no usage data. Nothing phones home. No anonymous usage stats. No crash reports. Nothing.

Your files are encrypted on your device before they leave it. The server stores only encrypted blobs it cannot read. Your passphrase and encryption keys never leave your machine. See the security model for the full details.

This marketing site (contextmate.dev) uses PostHog for basic, anonymous analytics. We track:

• Page views (which pages are visited)
• Install command copies (did someone click the copy button)
• General traffic sources and geography (country-level)

We do not track:

• Personal identity (no login, no email collection)
• Cross-site browsing behavior
• Detailed device fingerprinting

All analytics profiles are anonymous. We use this data to understand whether our documentation is clear and which parts of the site people find useful.

PostHog sets a first-party cookie to distinguish unique visitors. No third-party advertising or tracking cookies are used. Google Fonts and Fontshare are loaded for typography; they may set their own cookies per their respective privacy policies.

The entire ContextMate codebase, including this website, is open source. You can inspect exactly what data the product collects (none) and what this site tracks (the PostHog snippet in our page source).

Open an issue on GitHub or reach out to the maintainers. We're happy to answer anything about how we handle data.
