How to use Claude 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: never rely blindly on AI output for figures or tax rules: have an accountant verify everything.

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
From 26 October, the Swedish government office blocks ChatGPT and Claude on work computers because there is no formal contract and there are information security risks; Microsoft Copilot remains permitted. Business use therefore requires a contract with data processing terms. source
