Privacy Policy

When you run a scan, the app processes the URL you submit so it can fetch and analyze the public HTTP headers for that site.

Server logs may include basic request information such as IP address, user agent, timestamp, and requested path. These logs are used for reliability and abuse prevention.

HeaderCheckr does not need passwords, private tokens, or access to your server. Only scan public websites that you are allowed to check.

Do not submit private internal hostnames or confidential URLs.

If ads are shown on HeaderCheckr, advertising partners such as Google may use cookies, device identifiers, or similar technologies to show ads, measure performance, and prevent abuse.

Google may use information from this site and other sites to personalize ads depending on your settings. You can learn how Google uses data from partner sites at https://policies.google.com/technologies/partner-sites.

You can control cookies through your browser settings. You can also manage Google ad personalization in your Google account settings.

Blocking cookies may affect some website features, but the core security header checker is designed to work without an account.
