DeepSeek has a concrete GDPR concern. The DeepSeek service stores personal data in China and was blocked by the Italian regulator in 2025 January. Not advisable for regulated sectors unless you host the model yourself within the EU. Weigh this heavily before deploying it in notarial work.
Confidentiality and GDPR
GDPR: CautionNotaries are bound by strict confidentiality (art. 22 Wna) and liability for the content of deeds. Client data is personal data under the GDPR; audio recordings of signing meetings must not be sent unencrypted to external servers. Only use systems with EU hosting and a data processing agreement, where input is not used for model training. AI output for deeds and advice always requires verification by a qualified notary.
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.
