Privacy Policy

Last updated: July 4, 2026

Tidesman is a free MCP server that runs entirely on your Mac. This policy explains what information Tidesman handles, where it goes, and what stays with you. The short version: Tidesman collects nothing about you, and it sends nothing to us.

What Tidesman collects

Nothing. Tidesman has no telemetry, no analytics, no crash reporting, and no user accounts. It never phones home. We receive no data from your use of it.

What Tidesman stores on your Mac

Tidesman keeps an audit log so you can see what your AI assistant did with it. Every tool call is recorded to ~/Library/Logs/tidesman/audit.log and to the macOS unified log: the tool's name, its arguments, and the outcome. Values that look like secrets (the contents of environment variables) are redacted before they are written. A command's own text is logged as given, so pass secrets as environment variables rather than typing them into command lines.

These logs never leave your Mac unless you share them yourself. They are yours to inspect or delete at any time; the log file rotates by size automatically.

Where Tidesman connects

Tidesman opens no network ports and accepts no inbound connections. It talks to two things: Apple's container engine, locally on your Mac, and a container registry (such as Docker Hub), only when you or your AI assistant asks it to pull an image. That request necessarily shares the requested image name and your network address with the registry, the same as any container tool. The registry's own privacy policy governs that interaction.

Third parties

Tidesman shares no data with third parties, because it has none to share. There are no ads and no analytics providers, and nothing is ever sold. The only third-party contact is the registry interaction described above, and you initiate it.

Retention

We retain nothing, because nothing reaches us. The local audit log remains on your Mac until you delete it.

The website

tidesman.dev is a static site. It sets no cookies and runs no analytics.

Changes

If Tidesman's behavior ever changes in a way that affects this policy, this page will be updated and the change noted in the release notes.
