SimpleMind is a mind mapping and brainstorming app for Mac, Windows, iPhone, iPad and Android. Users arrange ideas as branches around a central topic. The app is a program installed on the device, and the maps are files that the user keeps.
The publisher is ModelMaker Tools B.V. in Velp, the Netherlands; the privacy policy also names xpt Software & Consulting B.V. in Delft. According to the publisher, maps are not stored on its servers, so the company has no access to them. Users choose whether to sync, and through which cloud service such as Dropbox. The privacy policy does mention Google Analytics, whose data is stored on servers in the United States, and a customer database whose location is not stated. The policy text does not refer to the GDPR or a data processing agreement. For a European organisation, the sovereignty question therefore depends mainly on the sync service it chooses.
