MedicalConcept is practice software for independent doctors, developed by Advanced Concepts AG in Ossingen, Switzerland. According to the vendor it covers everything from billing to the electronic patient record. It runs on Apple macOS and Microsoft Windows computers, so it is installed in the practice rather than used in a browser, and support is offered by remote maintenance. The vendor describes it as a solution built from practice experience on the Omnis development environment.
Advanced Concepts AG is headquartered in Switzerland, and its website names no foreign parent. Switzerland is not an EU member but an EFTA country, and the EU has recognised its data protection level through an adequacy decision. Because MedicalConcept is installed on practice computers, patient data stays on systems you control; the vendor states no hosted option or storage location. Patient records are health data, so ask about backups and about what a remote-maintenance session can reach. The website's privacy page covers only the website, so agree a processing contract with the vendor.
