In the EU. Its sub-processor list names UpCloud in the Netherlands for hosting and OVHcloud in Germany for encrypted backups. Lettermint B.V. is a Dutch company, and its DPA is governed by Dutch law.

### Does Reloop have an EU region?

Yes. Reloop Cloud runs on Hetzner, with EU data centers. It comes with a DPA based on the EU Standard Contractual Clauses and a public sub-processor list. If you want full control over where data lives, you can also self-host Reloop on your own EU server; it's the same open-source code.
