Your code stays on your Mac

This page is a summary. The full policy ships inside the app, in Settings › About, and the app's version of it is the authoritative one.

The app

• There is no Suijin account, and Suijin sends no telemetry or crash reports.
• Your repositories, the agents' conversations and your settings are stored on your Mac, under ~/Library/Application Support/Suijin.
• The agents and tools you run (Claude Code, Codex, git, the GitHub CLI, your shell) talk to their own services with your own logins, as they do in any terminal. Their providers' terms and policies apply to that.
• Suijin never changes your own logins in ~/.claude or ~/.codex.

Connections the app makes itself

• Updates. About once a day, and when you choose Check for Updates, the app asks suijin.app whether a newer version exists. The request carries the app's name and version. An update is downloaded from Suijin's releases on GitHub. You can turn the automatic check off in Settings › General.
• Usage limits. To show how much of a plan is used, the app asks Anthropic or OpenAI with that login's own token.
• GitHub. If the GitHub CLI is installed, the app uses it with your own sign-in to show and create pull requests you ask for.

What suijin.app keeps

• Update checks are counted per day and app version, to estimate how many copies are in use. Nothing else is kept about them: no address and no identifier.
• This website sets no cookies, runs no analytics and loads nothing from third parties, with one exception that you start yourself: the introduction video.
• The introduction video is hosted by Mux. Nothing is requested from Mux until you open the video. From then on your browser loads the player and the video from Mux, which receives your IP address and browser details to deliver them and measures playback. See the Mux privacy policy.
• The site is served by Cloudflare, which processes requests, including IP addresses, to deliver pages and protect the service.
