if you connect an AI provider yourself (including OpenAI, Anthropic or Google) with your own key, that provider's terms apply to your text (according to the provider); Estse (EU) company; data is stored by default in the AWS data centre in the US (us-east-1); an EU data centre (AWS Ireland) can only be chosen with Crowdin Enterprise (according to the provider); ISO/IEC 27001 certified and GDPR compliant (according to the provider); data processing agreement (DPA) with Crowdin as processor (according to the provider); if you translate personal data, choose Crowdin Enterprise with the EU data centre

How to use Crowdin 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.

9 November 2026Claude Code stores approved commands containing passwords in settings.local.json

If you choose "Yes, and don't ask again" in Claude Code, the tool saves the command verbatim in .claude/settings.local.json, including passwords or API keys. Apiiro found real secrets in 1,122 of 104,185 public copies on GitHub, including 379 database passwords. Keep the file out of git, use variables for secrets, and replace any keys that have already leaked. source

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

November 2 2026Message threads (beta) fall outside Zero Data Retention

With message threads in the Claude API, Anthropic stores the conversation, the system prompt and the tools on the server, encrypted in memory and not on disk, until up to one hour after the last use. The feature does not qualify for Zero Data Retention; your other ZDR agreements still apply. If you work with personal data under ZDR, only enable threads if your DPIA covers it. source

Questions

How safe is Crowdin for translation & localisation?
Crowdin has a strong published GDPR profile and, with the right business settings, is well suited to translation & localisation. EU options, no training on your data and/or self-hostable.
Does Crowdin train on my data?
if you connect an AI provider yourself (including OpenAI, Anthropic or Google) with your own key, that provider's terms apply to your text (according to the provider); Estse (EU) company; data is stored by default in the AWS data centre in the US (us-east-1); an EU data centre (AWS Ireland) can only be chosen with Crowdin Enterprise (according to the provider); ISO/IEC 27001 certified and GDPR compliant (according to the provider); data processing agreement (DPA) with Crowdin as processor (according to the provider); if you translate personal data, choose Crowdin Enterprise with the EU data centre
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.
