How we handle data when you use Port Checker.
Last updated: October 17, 2026
Data we collect
We process the host and port values you submit to perform connectivity checks. We also collect standard technical logs such as request time and coarse diagnostic metadata for stability and abuse prevention.
How we use data
Data is used to deliver requested checks, maintain service reliability, investigate incidents, and improve product quality. We do not sell personal data.
Advertising and cookies
Port Checker is free to use because it is supported by advertising. Google AdSense and its partners use cookies to show ads based on your previous visits to this and other websites, and may process your IP address, approximate location, and browsing activity for that purpose. We do not set advertising cookies ourselves and cannot read or control those set by third parties. You can turn off personalized advertising in Google Ads Settings (google.com/settings/ads) or manage cookies in your browser; ads will still appear, but they will be less relevant to you. You can also opt out of personalized advertising from other participating vendors at aboutads.info.
Retention and security
Operational logs are retained for a limited period and protected with access controls. We continuously review safeguards to reduce unauthorized access risks.
