How to use Weglot safely

  • Use the business variant and sign a data processing agreement (DPA).
  • Do not enter unnecessary personal data into prompts; anonymise where possible.
  • Enable EU data residency where the provider offers it.
  • 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.

Latest developments

5 November 2026Flaw in Lockdown Mode patched

Via pop-up windows in the HTML preview of code blocks, an attacker could bypass Lockdown Mode and siphon off your chat history, via a manipulated prompt, GPT or shared chat. OpenAI patched the flaw on 18 September 2026; Check Point published the details on 5 November. Users do not need to do anything. source

1 November 2026Reports to the police and stricter rules for teens

In the third quarter of 2026, OpenAI made more than 200 reports to law enforcement about threatened violence based on ChatGPT conversations. Conversations in which someone appears fixated on violence may be ended automatically by ChatGPT, and if it happens repeatedly, OpenAI can pause the account. So don't assume that what you type into ChatGPT stays confidential. source

27 October 2026Connection with iCloud Mail and Calendar on all subscriptions

ChatGPT can use plugins to search and summarise iCloud mail and change appointments, including on the free subscription. Signing in uses an app-specific password from Apple; it remains valid if you disconnect the integration in ChatGPT and you must revoke it yourself via account.apple.com. source

Questions

How safe is Weglot for translation & localisation?
Weglot has a good GDPR profile. Usable in translation & localisation, provided you use the business version and follow the points of attention below. Good safeguards, but not on every point.
Does Weglot 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.
