SealMetrics was built from scratch to solve this — without cookies, without consent dependency, and without compromising privacy. [Book a demo →](https://sealmetrics.com/demo/)[Start 14-day trial](https://my.sealmetrics.com/register) 5-minute setup · No cookies · EU-hosted by design TL;DR SealMetrics is a cookieless web-analytics platform that captures 100% of website traffic anonymously, then attributes each conversion last-click at channel level for revenue decisions. The architecture is three layers: an **846-byte first-party pixel** logs each pageview directly from your own domain (no third-party cookies, no ad-blocker impact, no consent banner integration); a **server-side pipeline in Dublin** counts events anonymously and joins them to the channel observed on each pageview; a **reporting and API layer** exposes aggregate totals to dashboards, BigQuery, MCP servers and AI agents. Implementation takes 15 minutes for the script tag, runs side-by-side with GA4 from day 1 (no migration), and reaches full calibration within one week. Hosted exclusively in Dublin, Ireland on EU-owned infrastructure, with no sub-processors outside the EU in the visitor data path. - One JavaScript tag — works on any CMS, SPA or headless setup. - Aggregate, anonymous counts — no user identifiers, no per-visitor journeys, no session stitching. - GDPR-compliant by architecture (no cookies, no PII, EU-only processing). - Side-by-side with GA4 from day 1 — no migration required. ## The *single source of truth* eCommerce signs against **Dreamplace Hotels** recovered **+30% more traffic** vs GA4 and closed a **15–20% gap** in sales attribution against their CRM. **Palladium Hotel Group** recovered **35% of unattributed bookings** and improved Display CPS by **+165%**. ![Palladium Hotel Group](https://sealmetrics.com/logos/clients/palladium-dark.svg) ![Dreamplace Hotels](https://sealmetrics.com/logos/clients/dreamplace.svg) ![Acciona](https://sealmetrics.com/logos/clients/acciona.svg) ![Crocs](https://sealmetrics.com/logos/clients/crocs.svg) ![Desigual](https://sealmetrics.com/logos/clients/desigual-dark.svg) ![UNICEF](https://sealmetrics.com/logos/clients/unicef.svg) ![Casa Batlló](https://sealmetrics.com/logos/clients/casabatllo.png) ![Juguettos](https://sealmetrics.com/logos/clients/juguettos.png) ![3Cat](https://sealmetrics.com/logos/clients/3cat.png) ![Fundación Bankinter](https://sealmetrics.com/logos/clients/fundacion-bankinter.png) ![Dormideo](https://sealmetrics.com/logos/clients/dormideo.png) ![Incapto](https://sealmetrics.com/logos/clients/incapto.svg) In one sentence ## What is SealMetrics?

Key facts Category Consentless web analytics for European enterprises Founded 2020 Headquarters Spain · Data in Dublin, Ireland Customers 2,000+ European eCommerce (hotels, DTC, media) Pricing From €499/month on annual billing Compliance GDPR by architecture · ePrivacy · Schrems II clean Differentiator 100% traffic captured without cookies · native MCP for AI agents Architecture ## Three layers. *One pipeline.* Traditional analytics depend on third-party cookies and browser-side tracking. SealMetrics flips the model: first-party collection, server-side processing, EU-hosted storage. All designed so consent rejection, ad blockers and Schrems II stop being your problem. 01 · Collect ### 846-byte first-party pixel A tiny JavaScript tag, 846 bytes at its minimum and 1.1 KB on the wire in full. It ships from t.sealmetrics.com by default, and you can switch it to a subdomain of your own — first-party mode — so ad-blocker lists that target third-party analytics domains have nothing to match. No cookies are written. No local storage. No fingerprinting. - Optional first-party mode on your own subdomain - 1.1 KB on the wire · ~132× lighter than GA4 - Works with any CMS or framework - 5-minute install · one script tag 02 · Process ### Anonymous server-side event counting Events are processed on our servers, not in the browser. Each pageview is logged with anonymous channel metadata (referrer, UTM, landing page) and aggregated into channel totals. No user identifier, no session stitching, no cross-visit linking. Zero sampling at any scale. - No client-side aggregation - No per-user identifiers · no session stitching - 100% of events kept · no thresholds - Real-time stream under 2 minutes 03 · Store ### EU-hosted · Dublin, Ireland Visitor data lives exclusively on EU infrastructure — no transfers outside the EU, no sub-processors in third countries, no reliance on Standard Contractual Clauses. The single non-EEA transfer anywhere in the service is account-user service email via Resend (USA, SCCs + EU-US DPF), which touches no visitor data. GDPR-compliant by architecture, not by a legal layer bolted on afterwards. - Dublin, Ireland — Schrems II clean - No third-country sub-processors in the visitor data path - 24 months data retention included - GDPR · ePrivacy · Schrems II clean Implementation ## From install to *decision-ready* in one week. Runs alongside GA4. No migration, no disruption. One script — same as any analytics tool — but without the cookie banner and without the sampling.
