Privacy Policy — Metsuke Interview Guard

Last updated: 2026-06-06 · This is the authoritative version. Reference translations: 繁體中文 · 日本語.

Metsuke Interview Guard ("the extension") is a read-only safety tool for developers reviewing source code on GitHub, GitLab, and Bitbucket. This policy explains exactly what the extension does and does not do with your data.

Summary — The extension does not collect, store, transmit, or sell any personal data.
All analysis runs locally in your browser. There are no accounts, no tracking, no analytics, and no telemetry.

Data we collect

None. The extension does not collect or transmit any of the following: personally identifiable information, health information, financial or payment information, authentication information, personal communications, location, web history, user activity, or website content.

Network requests

The extension makes exactly one kind of network request: when you are viewing a file or repository page on GitHub, GitLab, or Bitbucket, its background service worker fetches the raw source of the file you are already viewing (or a small, fixed set of well-known configuration files for the repository you are on), from the same code host you are already browsing. This is necessary because the rendered page often hides code off-screen, and accurate analysis needs the true source.

No third-party servers are contacted. The fetched source is analyzed in memory and is never uploaded, logged, or persisted.

Data stored on your device

The extension stores only two small preferences using chrome.storage.sync, so they follow your Chrome profile:

The global on/off switch.
Your trusted-repository allowlist (repositories you chose to silence).

No page content, source code, or analysis results are stored.

"Copy for your trusted AI" feature

When you click this optional button, the extension copies a short text summary of the detected signals to your clipboard only. Nothing is sent anywhere automatically — you decide whether and where to paste it. If you paste it into a third-party AI service, that service's own privacy policy applies to what you paste.

Remote code

The extension uses no remote code. All detection rules and logic are bundled in the package. There are no external scripts, no remotely-hosted modules, and no evaluation of remote strings.

Permissions

storage — remembers your on/off switch and trusted-repository list (above).
Host access to github.com, gitlab.com, bitbucket.org, raw.githubusercontent.com — runs the local analyzer on the page you are viewing and fetches the raw source of that file for accurate analysis.
