DeepSeek has a concrete GDPR concern. The DeepSeek service stores personal data in China and was blocked in January 2025 by the Italian regulator. Advised against for regulated sectors, unless you host the model yourself within the EU. Weigh this heavily before deploying it in accountancy.

Confidentiality and GDPR

GDPR: Caution

Never rely blindly on AI output for figures or tax rules: have an accountant verify everything. Mind the confidentiality of client records.

The DeepSeek service stores data in China and uses it for training by default (with an opt-out). Only an EU self-hosted variant of the open weights is defensible for sensitive data.

Rule of thumb Use the business variant with a data processing agreement, and keep a human in the loop for decisions that matter.
