Queries and network requests
The hosting service processes your request IP and necessary network request information. IP and domain queries and network tests send the relevant target to the selected data source or diagnostic service. Third-party sites contacted directly by your browser can also see that connection’s egress IP.
Browser checks
Browser diagnostics read and display the environment, fingerprint or permission information needed by the selected checks. The consistency page automatically starts local deep diagnostics. Some network checks and optional CAPTCHA features contact third-party services.
Local storage
This site stores theme and notice preferences along with lookup history in the current browser. Lookup history includes recent successful queries and results. Queried addresses may also appear in browser history. You can clear local data through your browser’s site data settings.
Third-party data processing
IP health queries send the queried public IP to Net.Coffee. Other queries, maps, site resources and verification features process necessary request data through their respective services. Third-party and hosting data processing and log retention depend on their policies and actual configuration.
Third-party services used
IP lookups may contact ipwho.is, ipquery.io, IP.SB or ipify; IP health uses Net.Coffee. Global ping sends targets and probe selections to Globalping; maps prefer Tianditu and fall back to OpenStreetMap when it is not configured or unavailable; service status reads providers’ public endpoints. Requests depend on the pages and checks you select.
WebRTC and device permissions
WebRTC checks connect to Google and Cloudflare STUN services and may reveal an egress address different from web requests. Camera, microphone and location tests start when clicked and are controlled by browser permissions. Media permission tests close the stream immediately without recording audio or video. Revoke permissions in browser settings.
Optional CAPTCHA
When configured and used, CAPTCHA features load Cloudflare Turnstile or Google reCAPTCHA. This site forwards verification tokens to the provider for validation. Those services also process device and network signals under their own policies.
Retention and deletion
Lookup history keeps the latest 10 successful queries and results per category in the current browser; clear site data to remove it. The server uses request IPs for rate limiting. Hosting configuration enables sampled logs; actual records and retention depend on deployment settings. Clearing browser data does not remove third-party or hosting records. Contact the author with the request time and feature for data questions.
