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, third-party vendors, including Google, may use cookies, web beacons, IP addresses, device identifiers, or similar technologies to serve ads, measure performance, personalize ads where allowed, and prevent abuse.

Google's use of advertising cookies enables Google and its partners to serve ads based on visits to HeaderCheckr and other sites on the Internet. 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 or opt out of personalized Google advertising at https://adssettings.google.com.

You may also opt out of some third-party vendors' use of cookies for personalized advertising at https://www.aboutads.info. Blocking cookies may affect some website features, but the core tools are designed to work without an account.

Depending on your location, HeaderCheckr may ask for consent before loading advertising or analytics technologies that are not strictly necessary.

If a consent notice is shown, use it to accept, reject, or manage optional cookies and similar technologies.
