For an AI system to take work off your hands, it gradually builds up knowledge about your business: processes, appointments, documents, decisions. Here is where that knowledge lives, in what form, and why you keep it in your hands at all times.
Each client instance runs on its own server in Europe, assigned to you. Not in a shared US-corporation cloud, not mixed with anyone else's data.
Your knowledge is simple text files, not a secret database format that locks you to one program. You can open, search and copy them with any editor.
No provider can lock it away. You can download and take everything at any time. If you leave, you leave with all of your knowledge. That is what we mean by no lock-in.
