And also, you're completely wrong.
As a Plausible customer, your data is never processed in the US, or sent to the "cloud" outside of EU.
I wonder what Paul thinks of your attempts to fear monger people into thinking your crappy product is superior to an open-source alternative.
But hey man, good luck with Fathom. It will be a great success.
Using EU servers that are owned by a US company (e.g. AWS deployed in the EU, DigitalOcean deployed in the EU) is a violation of the Schrems II ruling. The way you check this is by looking at the IP addresses the analytics software are using, seeing where they're located and who they're owned by. You can then run that IP in ipinfo.io to get information about who controls that IP. If it's a US cloud provider, regardless of server location, it's a GDPR violation.
The English translation of the ruling can be found here. They go into detail within the rulings about the transfer of Personal Data (IP & User Agent) to servers that cannot be protected from US surveillance laws: https://noyb.eu/sites/default/files/2022-01/E-DSB%20-%20Goog...
"This is a very detailed and sound decision. The bottom line is: Companies can't use US cloud services in Europe anymore. It has now been 1.5 years since the Court of Justice confirmed this a second time, so it is more than time that the law is also enforced." - Max Schrems
For our self-hosted version, you can install it with any cloud provider and in any country you wish. Even in the USA. That's the testing one we had on our site as we're testing the latest release of our self-hosted version on our own website. This has nothing to do with what our customers place on their sites.
You were using Netlify previously, which is a US provider and backed by AWS, and then Cloudflare for the testing.
But yesterday I can see you moved to Bunny (an EU cloud provider), which is great news for your customers, party time!
Provided you’re using Hetzner behind Bunny, that looks like solid Schrems II compliance to me.
