Your AI Translation Tool Might Be Training on Your Business Data — Here’s What to Do About It

Summary

Businesses using AI translation tools face significant data exposure risks, as content sent to third-party machine translation (MT) providers or large language models (LLMs) may be used for model training by default. This practice carries substantial legal weight, particularly under GDPR, which considers AI models trained on personal data subject to its regulations due to their memorization capabilities. Recent regulatory actions, such as the European Data Protection Board's Opinion 28/2024 and Italy's €15 million fine against an AI company, underscore the urgency of data governance. Companies must secure a Data Processing Agreement (DPA) with translation providers, explicitly disclose AI usage, and ensure human oversight for sensitive content, especially for EU-based operations or data from EU citizens. While Machine Translation Post-Editing (MTPE) is suitable for high-volume, structured content, it is inappropriate for legal, financial, HR, or brand-driven materials where precision and liability are critical.

Key takeaway

For legal teams and operations managers handling sensitive business data, you must scrutinize your AI translation providers' data handling policies. Ensure your provider offers a GDPR-compliant Data Processing Agreement and explicitly details their machine translation engine usage to prevent your proprietary information from inadvertently becoming training data for general-purpose AI models. Prioritize human-first translation for legal, financial, and HR documents to mitigate compliance risks and maintain accountability.

Key insights

AI translation tools can expose sensitive business data to model training, creating significant GDPR compliance risks.

Principles

• AI models trained on personal data are subject to GDPR.
• DPAs are legally required for third-party data processing.
• Human oversight is critical for sensitive content.

Method

A hybrid approach combining professional human translation with carefully controlled AI assistance, known as MTPE, is often most practical for business translation, but requires strict data governance.

In practice

• Require a signed Data Processing Agreement (DPA).
• Demand explicit AI usage disclosure from providers.
• Prioritize human review for legal and HR documents.
