Cookie Policy

Effective March 18, 2026Last updated March 18, 2026

This Cookie Policy explains how Commentary uses cookies and similar technologies on commentary.dev and related review routes.

Commentary uses necessary cookies to keep authentication and basic routing flows secure. Commentary also supports optional tracking cookies for privacy-safe usage measurement when you accept them.

Necessary cookies

These cookies are required for core product behavior and cannot be rejected through the cookie banner:

  • commentary_session: Keeps the browser-wide Commentary viewer session and active GitHub account available for authenticated review actions. Retention: Up to 30 days.
  • commentary_oauth_state: Protects the GitHub App sign-in flow against request forgery during authentication. Retention: Up to 10 minutes.
  • commentary_oauth_redirect: Returns the user to the Commentary route they were on after GitHub authentication completes. Retention: Up to 10 minutes.
  • commentary_cookie_preferences: Stores the user’s cookie-consent choice so the consent banner respects that decision. Retention: 180 days.

Optional tracking cookies

Commentary uses optional tracking cookies only after you accept them. These cookies help Commentary understand usage patterns, signed-out traffic, and product reliability without relying on raw GitHub identifiers.

  • commentary_anonymous_id: Supports privacy-safe usage tracking for signed-out and read-only traffic. Retention: 365 days.

How to manage preferences

When optional cookies are active, Commentary shows a consent banner that lets you accept or reject them. Commentary stores that choice in a necessary preference cookie so the banner respects your decision.

You can also clear Commentary cookies in your browser settings, disconnect your GitHub session from the app, or contact privacy@commentary.dev if you need help.
