If you want to use EU isolation, congratulations; as a Fathom customer, you’re already using it, and it’s enabled by default!
There’s nothing you have to set up or tweak or even change in your embed script to use it. Fathom automatically and intelligently routes data from EU visitors to be processed in the EU and all other visitors to be processed in the US.
EU isolation provides compliance and speed in loading your script and processing the data.
You can turn on ‘Extreme mode’ in the script settings of your site, which will process all visitor data in the EU. This slows things down fractionally (as all traffic routes to the EU, regardless of how far away a visitor is), but if you’re worried about data processing outside the EU, we offer this as an option (it’s turned off by default of course). Note: Extreme mode is only available if you are using a custom domain.
Either way, Fathom always practices data minimization and upholds privacy laws in how our software works and how we put protecting the privacy of website visitors around the world as our highest value.
If you still have questions or require help with anything, please reach out to us and we'll happily get things sorted out for you.
