DeepL Privacy Policy

This is DeepL's privacy policy, explaining how DeepL collects and uses your personal data when you use its translation services, apps, and website. The most important thing to know is that if you use the free DeepL translator, the text you type in — including potentially sensitive or confidential content — may be used by DeepL to train and improve its AI models. You can avoid this by using DeepL API Pro or a paid subscription plan, which DeepL states does not use your translations for training purposes.

This document is DeepL's privacy policy governing the collection, processing, and use of personal data by DeepL SE and its affiliates, with legal bases under GDPR Art. 6(1)(a) (consent), 6(1)(b) (contract performance), and 6(1)(f) (legitimate interests) for EU/EEA users, and equivalent frameworks for other jurisdictions. The policy creates obligations for DeepL to provide data subject rights (access, erasure, portability, restriction, objection) and imposes user obligations regarding the accuracy of submitted data, including translations which may contain third-party personal data. A notable provision allows DeepL to use text submitted via the free/non-API translator for product improvement and AI model training purposes, which deviates from expectations users may have about the confidentiality of translated content and creates meaningful risk for users translating sensitive or confidential material. The policy engages GDPR (EU 2016/679), the UK GDPR, CCPA/CPRA for California residents, and references adequacy decisions and Standard Contractual Clauses for international transfers; material compliance considerations include the use of translated input data for model training without granular opt-out for free-tier users, and the identification of DeepL SE (Maarweg 165, 50825 Cologne, Germany) as the primary data controller with a designated DPO reachable at privacy@deepl.com.
