Privacy Policy

NAT Checker has no accounts and no sign-up. Our servers keep standard request logs such as IP address, device type and timestamps for 7 days to keep the service reliable and prevent abuse, then delete them.

NAT detection uses WebRTC in your browser. This may reveal your network information to perform connectivity tests.

We use collected data to operate the service, detect abuse, and improve reliability.

We do not sell your personal information and we do not build advertising profiles ourselves. Personalised ads are served by Google, as described under Advertising.

This site is funded by Google AdSense. Google and its partners may set cookies and use device identifiers to show personalised ads based on your visits to this and other sites. You can review or turn off personalised advertising at google.com/settings/ads.

We may use minimal cookies or analytics to understand site usage and improve performance.

Some diagnostics may rely on third-party endpoints for connectivity checks. These services may receive your IP address as part of the request.

We may update this policy from time to time. Continued use means you accept the updated policy.
