DeepL analyses translation texts to improve its services, but claims to anonymise data before doing so. Paid DeepL Pro subscribers' content is specifically not used to train the translation AI.
Free users' translation content is subject to anonymised analysis for AI improvement purposes, while DeepL Pro subscribers' texts are explicitly excluded from model training — meaning the privacy protection for translation data depends on which subscription tier you use.

Compare across platforms →Free-tier users should be aware their translation content may be analysed to improve DeepL's AI systems, while Pro subscribers have an explicit carve-out — this is a meaningful distinction that affects which plan users should choose if data use is a concern.
REGULATORY FRAMEWORK: This provision engages GDPR Art. 5(1)(b) (purpose limitation), Art. 5(1)(c) (data minimisation), and Art. 89 (safeguards for processing for scientific or statistical purposes). The key question is whether anonymisation is effective under GDPR Recital 26 — if data can be re-identified, GDPR obligations apply in full. The EU AI Act (Regulation 2024/1689) may impose additional obligations regarding training data governance. Enforcement authority is the German BfDI and national DPAs for EU users; the ICO for UK users.
