Check third-party requests with browser DevTools

Prerequisite

Open browser DevTools before accessing the page and empty the network log.

Clear network log before loading, activate Preserve Log for redirects and reload the page. Check domains, request types and timing. Then test interactions such as forms, videos or consent separately.

The specific read-only commands are collected under Check the website yourself.

Rate result

A single hit is a technical finding. Then check the purpose, actual storage, transfer and retention period of the affected level separately.

Classify in the overall check

This individual test only covers one level. Then systematically check the remaining levels using the checklist for unnecessary visitor data .

Important: IP processing is not IP storage

An IP address has to be processed to establish and deliver a network connection. Hosting providers, firewalls or DDoS protection may also process or retain it for a limited time for security purposes. No Logging distinguishes this security layer from unnecessary persistent visitor logging by the website, application and ordinary access logs.
