How cookieless analytics comply with GDPR requirements and provide better data without consent banners
Step-by-step Sealmetrics guides — cookieless analytics implementation, GDPR compliance, and platform best practices.
Fathom hashes IP and user agent daily and stores anonymised data in the US after EU processing. Sealmetrics never hashes the IP and keeps all data in Dublin.
Plausible identifies visitors with a daily hash of IP and user agent; Sealmetrics never derives an identifier from the IP. Both cookieless, both EU-hosted.
Both skip cookies and IPs, say no consent banner is needed and derive country from the timezone. Simple Analytics keeps it minimal; Sealmetrics adds attribution, e-commerce and AI.
A technical comparison of tracking pixel weight, delivery chain, and time-to-first-hit: the Sealmetrics tracker vs the Adobe Analytics stack (Launch + AppMeasurement) — with field measurements from a real site running both, methodology included.
Sealmetrics t.js measures 1.1 KB on the wire — 12× lighter than the legacy v1 tracker and ~132× lighter than GA4 gtag.js; Matomo and Piwik PRO sit between.
The three-way comparison: tracking pixel weight, delivery chain, time to first hit, transport, consent, and measured traffic differences between Sealmetrics, GA4's gtag.js, and the Adobe Launch + AppMeasurement stack.
