Data protection and professional law

Before the first record we sign an agreement under § 62a StBerG in text form with instruction and disclose all subcontractors. We act as a contributing person under § 203 StGB, with a data processing agreement and no training on client data. In the sprint we use pseudonymised data or the pilot clients' consent. Final review stays with your firm. EVORI provides no tax advice; the assistant only creates drafts.

Reference

At BVM our AI platform creates posts in the association's brand: about 45 minutes per post before, under a minute today. A person approves each one. We approach your case the same way.
