- DATEV Copilot (cloud application in MyDATEV; available only to tax advisers and auditors)
DATEV Copilot FAQ: 'Is my data used to train the AI? No, neither Microsoft nor OpenAI use your data for training.' (translated). Copilot is a DATEV cloud service under the DATEV service descriptions for the DATEV-Cloud-Lösungen Basis (doc. no. 0904407); unlike the service descriptions for Rechnungswesen, Steuern, Personalwirtschaft and Wissen, these contain no clause on cross-customer processing for 'Intelligente DATEV-Cloud-Lösungen'. Item 3.8, however, permits DATEV to process data 'for the purpose of developing new or further developing existing DATEV products in an appropriately secured environment' (translated); according to item 3.8 this does not apply if the customer concluded the DPA without the anonymisation agreement (deletion possible under DPA item 15). An express statement on DATEV's own model training with Copilot inputs is missing.
- AI-supported DATEV cloud functions (Automatisierungsservice Rechnungen/Bank, Liquiditätsmonitor online, Datenprüfung, Einspruchsgenerator, Personal-Benchmark online)
DATEV service descriptions for the DATEV-Cloud-Lösungen Rechnungswesen (accounting), Steuern (tax) and Personalwirtschaft (payroll), each item 1.8 'Service-related cross-customer data processing' (translated) (identical wording also for Wissen [knowledge]): for 'intelligent cloud solutions' (translated), the customer instructs DATEV to use the data sets 'set up by the customer for the „Intelligente DATEV-Cloud-Lösungen“' (translated) 'in the context of new and further development, quality assurance and operation' (translated); 'For machine learning or deep learning, this training forms the basis for the systems' learning' (translated); 'for example, data of different customers of the „DATEV-Cloud-Lösungen“ are analysed together' (translated); 'Personal data may still be processed in the resulting AI models as well' (translated); special categories of personal data may also be processed. The application of the AI models remains 'exclusively a DATEV-internal process' (translated). No possibility of objection is described in item 1.8; according to its wording, the optional deletion of the anonymisation agreement (DPA item 15b) only affects items 3.7/3.8, not item 1.8. The Basis service description (Copilot) contains no item 1.8 of this kind. Payroll benchmark uses 'real, anonymised DATEV payroll records' (translated); de-identification service: data is 'analysed in the DATEV data centre' (translated) and de-identified before AI processing.
