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 10,868 domains checked here send data outside the EU.
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.
