Why this matters for digital sovereignty
Translation platforms process source documents that may contain confidential business information or personal data, so GDPR applies once texts are processed via cloud services outside the EU. Check whether documents are deleted after processing, where translation engines run, and whether on-premise or EU-hosted processing is available.
