External Services

This plugin does not connect to any third-party service by default. The following items are documented for transparency:

  • CSP report-uri: If you configure a report-uri in the CSP settings, the browser will send CSP violation reports to the user-provided URL. The plugin does not provide or operate that endpoint; the site administrator chooses and controls it. By default the report-uri field is empty and no reports are sent.

  • Example domains in settings fields: Inputs such as https://example.com and https://api.example.com use IANA-reserved example domains as placeholders only. The plugin does not connect to them.

  • GitHub documentation link: The admin sidebar includes a link to https://github.com/jeelsh/http-headers. It opens only when a user clicks it. GitHub is operated by GitHub, Inc.; for terms and privacy, see https://docs.github.com/en/site-policy/github-terms/github-terms-of-service and https://docs.github.com/en/site-policy/privacy-policies/github-privacy-statement.

  • Support email link: The admin sidebar includes a mailto:jeelsh@protonmail.com link. It opens the userÌtumọ̀ Yorùbá: ’s email client; the plugin does not send any data.

  • WordPress REST API and admin-ajax: Saving and validating settings uses the siteÌtumọ̀ Yorùbá: ’s own WordPress REST API endpoints and admin-ajax.php. These are same-site, internal communications.

Privacy

Jeelsh HTTP Headers does not collect, store, or transmit any personal data on its own. All header configuration is stored in your WordPress database. The only optional external communication is a CSP report-uri that you, the site administrator, choose to configure.
