Abs. 2
Careful selection of the provider. Our sub-processors, TOMs and ISO documents are public for that.
Abs. 3
Contract in text form: confidentiality with instruction on the criminal consequences, access only as needed, rules for further persons. You assess whether our annex to the DPA covers this.
Abs. 4 and 5
Services abroad only where secrecy protection is comparable; services for a single matter only with the client's consent. You assess both.

Where is our client data stored and processed?
Data is stored in Germany, primarily on STACKIT. Level 1 runs on STACKIT and our own infrastructure, Level 2 with GPT, Claude and Gemini in EU regions of their platforms.
Some models are only offered globally; if you expressly select one, inputs may be processed outside the EU.
Web search runs through Perplexity AI, Inc. (USA), only when you switch it on in the chat, and receives only the search query.
What do we sign on confidentiality, and when?
The DPA under Art. 28 GDPR, with our confidentiality undertaking and instruction under § 203 StGB as an annex. You generate it in the Trust Center, sign it, and we countersign. Do this before the first real client file goes in.
Do we need our clients' consent?
§ 43e Abs. 5 BRAO requires it where a service directly serves a single matter; § 39c PAO has a matching rule for patent attorneys. Whether that applies to your use is your call.
Providers, storage locations and sub-processors are in the Trust Center.
Can we decide which models our team uses?
Yes. Administrators decide which models are available in the workspace, for example Level 1 only.
We or our sub-processors run open models of Chinese origin, such as Qwen, Kimi and DeepSeek, on infrastructure in Germany or the EU.
How long is deleted data kept?
Deleted data leaves active systems immediately and backups within 30 days.
