DeepL

Translation That Stays in the EEA

DeepL translates text, whole documents and live speech, and its Write product rewrites and corrects text in the same interface. An API covers the same models for product integration, and glossaries let teams pin brand and product terminology so translations stay consistent across a site.

For marketing teams the practical use is localising landing pages, ads and email at a quality that needs light editing rather than a rewrite, and the document mode keeps formatting intact in DOCX and PDF.

Where the Data Goes

This is the part that separates DeepL from most language models on the market. The privacy policy states plainly that "the data is processed exclusively on DeepL's servers in the EEA, the data is not transferred to the USA", and that "the customer data is stored on servers in the EU".

The controller is DeepL SE of Maarweg 165, Cologne, a German company. The group includes DeepL US Inc. in Delaware alongside UK, Dutch, Polish and Japanese entities, but the parent is the German SE, so there is no non-EU corporate owner able to be served under the CLOUD Act.

Two US touchpoints remain and are worth knowing about. Traffic to the website is routed through Cloudflare for attack filtering, which the policy says may involve Cloudflare servers in the USA, and payments go through Stripe Payments Europe in Dublin, which may pass data to Stripe, Inc. in the USA. Neither touches translation content.

Free Versus Pro

The free translator is explicit that content sent to it is used to improve the service. The policy asks users to "only enter content that you wish to transfer to our services". Paid Pro plans are the ones that carry the data protection guarantees, so the free tier is the wrong place for client copy.

Other European options in this category are listed under translation and localisation.
