Privacy policy

We collect only what's needed to run the service: your email if you subscribe to the weekly digest, the content you choose to provide when submitting an error, and anonymized search terms used to improve coverage.

Your email is used only to send the digest you subscribed to; every email includes an unsubscribe link. We never sell or share it with third parties.

Sign-in uses a session cookie to keep you logged in, for authentication only — not cross-site tracking.

We use self-hosted analytics and Baidu Analytics to produce aggregate traffic, referral, device and browser reports for page quality review, troubleshooting and site improvement. These analytics are not used to process passwords, submitted error content or emails you choose to provide.
