Privacy policy
Data processed
The visitor IP is detected to display network information and processed in memory, without a database. Hosts and ports are used to run requested checks. We do not retain result history on the server; home page history remains in browser localStorage.
Technical logs
Access logs record time, method, path without parameters, status and duration, without IP or user-agent. Error logs may contain IP addresses and technical details for security and diagnosis, with daily rotation and up to 14 rotated files.
Cookies and local storage
We do not use our own tracking cookies. Local history stays on the device and can be removed with Clear history or by clearing browser data.
Third-party advertising
The site integrates Google AdSense. Google and partners may use cookies for ads based on previous visits. Manage personalized advertising in Google Ads Settings and consult how Google uses data from partner sites. NAI provides another opt-out option. Ad serving depends on service approval and availability.
Geolocation and queries
Geolocation uses local DB-IP Lite data (CC BY 4.0), without sending your IP to third parties for that lookup. Other tools query destinations, DNS resolvers or public registries needed for the requested diagnosis.
Rights and security
Under LGPD/GDPR you may request confirmation and access to any data retained, correction or deletion, withdraw advertising consent and delete local history. Use the contact page. The site uses HTTPS; diagnostics use the requested protocol, such as HTTP, TCP or DNS. Rate limits and private-network blocking reduce abuse. Material policy changes will be published with a new update date.
