Most websites send data to non-EU jurisdictions without their owners realising. Hosting, DNS, mail, fonts, external services: every layer counts. Check yours in a few seconds.
85% of the 9,460 domains checked here send data outside the EU.
Server locations now use the country each network publishes for its own IP ranges (RFC 8805 geofeeds) instead of the country the network is registered in. CDN and cloud networks such as CDN77, Bunny, AWS and Google Cloud now show where they actually serve from. CDN verdicts still follow who controls the provider. Older results are checked again on their next visit.
staysin.eu checks nine parts of a domain's setup: hosting provider, DNS nameservers, CDN, mail servers (MX), the services allowed to send its mail (SPF), server location, TLS certificate issuer, domain registrar, and the third-party services the website loads. The TLS issuer and registrar are shown for context; everything else decides the verdict. Read the full methodology
A service counts as EU when the company operating it is based in the EU, has no non-EU parent company, and runs its own infrastructure instead of reselling a non-EU provider. Where the IP address is announced is shown, but it doesn't change that verdict. If we don't recognise the operator, we fall back to the country of the IP address; the server location check always uses it. A domain stays in the EU when every scored service is EU. One non-EU service means it leaves the EU.
The score is the share of scored services that are in the EU: 5 EU services out of 6 gives 83. Hosting, DNS, mail, each outgoing mail sender, CDN (when one is detected), server location, and each third-party service count equally. The TLS issuer and registrar are shown but not scored.
When a non-EU company controls a service, its data can be subject to foreign laws such as the US CLOUD Act or FISA Section 702, wherever the servers are. Using EU-operated infrastructure keeps data under EU jurisdiction and reduces legal risk for businesses and public institutions.
