Privacy
Privacy notice
The service is designed to collect and expose as little information as practical for network diagnostics.
Requests and results
Inputs sent to server-side tools are processed to produce the requested diagnostic result. Dynamic diagnostic responses use no-store caching where applicable.
Browser-local tools, including encoding and browser capability detection, keep their input in the browser and do not transmit it to this service.
Operational data
The web server may process technical connection data such as IP address, timestamp, request path, status, and user agent in normal server logs. Security controls may use the effective client IP for rate limiting and abuse prevention.
Do not submit secrets, credentials, private keys, or personal data that is not necessary for the requested diagnostic.
Third parties
Some diagnostics query documented public infrastructure such as DNS resolvers, RDAP services, routing data services, or public HTTP(S) targets. Only submit targets you are authorized to inspect.
