Spree Commerce is an open-source, headless e-commerce platform built on Ruby on Rails. Its back end provides the shop functions while the storefront is built separately, as an alternative to hosted platforms such as Shopify. The BSD-3-Clause code can be self-hosted with Docker on AWS, Google Cloud, Azure or in a company's own data centres. A sandbox is available for evaluation; no hosted service for production use is described.
The vendor's privacy notice names Vendo Connect Inc, a Delaware corporation, as operator of the sandbox and states that Vendo is established in the United States. Personal data is stored and processed in the US and in other countries where Vendo's affiliates and service providers operate, so a hosted service run by that entity is subject to US law. Because the code is open source, a European organisation can run its own instance on servers in the EU and keep customer data under its own control. The privacy notice names Vendo as a GDPR controller and does not mention a data processing agreement.
