How to use Grok safely
- Use the business variant and sign a data processing agreement (DPA).
- Do not enter unnecessary personal data into prompts; anonymise where possible.
- Ask the provider explicitly where data is stored and processed.
- Keep a professional in the loop: client source documents often contain personal data or trade secrets: never use the free consumer version of a translation tool for client material.

From 7 November 2026, responses from grok-4.7, grok-4.6, grok-4.5, grok-4.3 and the grok-4.20 variants via the API will carry an invisible statistical watermark, to comply with the EU AI Act. The mark sits in the word choice and survives copying and pasting; the x-watermark header indicates whether a response is marked. A team administrator can switch it off per model, but must then confirm that a legal exemption applies. The detector is available on request only. source

- Does Grok train on my data?

- What should I watch out for with AI in translation & localisation?
- Client source documents often contain personal data or trade secrets: never use the free consumer version of a translation tool for client material. Require a data processing agreement, check that your texts are deleted after translation and not used for training, and choose EU hosting where possible. Many translation contracts and NDAs with end clients prohibit passing texts to third parties without consent, so document which MT engine you use. And stay responsible for the content: AI translations read fluently but can reverse figures, negations and legal nuances.
