TL;DR — How session-based tracking replaces cookies. Technical deep dive into Sealmetrics' architecture: hashing, token rotation, and data flow.

Introduction​

The Problem: Google Analytics loses 15-60% of EU visitor data to cookie rejections and banner ghosting — where you land depends on your sector, brand strength and traffic sources. Cookieless analytics solves this by tracking without cookies, consent banners, or IP addresses.

What You'll Learn:

• How cookieless tracking actually works technically
• Why it captures the data cookie-based tools miss
• The session-based architecture behind Sealmetrics
• Implementation differences vs traditional analytics
• The legal position: why no Article 6 basis is required at all

Key Takeaways:

• Cookieless tracking uses session identifiers instead of persistent cookies
• Zero IP storage means no personal data processing (no consent needed)
• 24-month retention on aggregates that contain no personal data
• Sealmetrics captures what GA4 misses: ghosted users, cookie rejecters, Safari/Firefox visitors

TL;DR — Cookieless analytics measures every visit without consent banners, closing the 15-60% gap cookie tools lose. Guide to implementation, GDPR, and comparisons.

Introduction​

Cookieless analytics has emerged as the solution to this data loss crisis. Unlike traditional cookie-based platforms like Google Analytics — which surrender 15-60% of their data to banner ghosting and rejection — cookieless analytics measures every visit without consent banners, cookies, or personal identifiers like IP addresses.

This complete guide explains how cookieless analytics works, why it's GDPR compliant without consent, and how platforms like Sealmetrics provide businesses with accurate, complete data while respecting user privacy.

Key Takeaways​

• Cookieless analytics measures every visit without cookie consent banners, closing a 15-60% gap
• No legal basis is required at all when no personal data is stored: the dataset falls outside the GDPR's material scope (Recital 26), and ePrivacy Article 5(3) is never triggered because nothing is written to the device
• Session-based tracking replaces cookies with temporary identifiers that reset after each visit
• Sealmetrics provides true cookieless analytics without storing IP addresses (unlike competitors)
