Cookieless tracking means measuring user behaviour without placing tracking cookies in the browser. Under GDPR, traditional cookie-based tracking requires explicit user consent — and many users say no. Cookieless methods reduce this dependency.

Common cookieless approaches include:

server-side tracking (data is processed on your own server, not sent from the browser to third parties directly), hashed identifiers (using anonymised email hashes instead of cookie IDs), aggregated measurement (grouping users by behaviour patterns rather than tracking individuals), and consent-based analytics (only counting users who have agreed to be tracked). 

Important to understand:

Just because a method is cookieless does not make it automatically GDPR compliant. If it still collects or processes personal data — even without cookies — GDPR rules still apply. Browser fingerprinting, for example, is cookieless but legally risky under GDPR. 

The safest approach:

Be transparent about what you collect, give users real control, minimise personal data collected, and use server-side processing so you control what leaves your system.
