Pirsch: cookieless with daily visitor ID from IP and user agent
Classification
Before use, decide whether daily recognition of unique visitors is even necessary or whether mere page views are sufficient.
Pirsch is cookieless, but recognizes visitors within a day using a hash of IP address, user agent, date and website salt. The raw IP is not saved according to the documentation. This is more data-efficient than long-term identifiers, but not the same as a pure page view counter without visitor recognition.
Check after the change
Check browser memory and network requests and also view web server, proxy, application and provider logs separately. A single product setting does not automatically cover the entire processing chain.
Basics of visitor recognition
For classification purposes, Cookieless is not automatically tracking-free and Use unique visitors without recognition . What is important is not just the presence of cookies, but also whether requests are merged via sessions, hashes, local storage or other features.
Reset
If the reduced configuration affects a required function, restore only the relevant setting and then recheck data flow, storage, retention and third-party connections.

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.
