Puzzle OKR is a tool for objectives and key results, developed by Puzzle ITC AG in Bern. It helps start-ups, small and medium-sized companies and autonomous teams align on shared goals and measure progress. The vendor offers it as software as a service and as open-source software you can run yourself; the source code is published under the GNU AGPL-3.0 licence and comes with a Docker setup. Puzzle ITC also offers consulting for introducing the OKR method.
Puzzle ITC AG is headquartered in Bern, with a German subsidiary in Tübingen; no parent group is named. The vendor does not state where the hosted service runs, so ask for the hosting location and processing terms if you choose the service. With the open-source version you operate the application yourself wherever you choose, which keeps control of data and operations with you. Switzerland is not in the EU but is an EFTA country with an EU adequacy decision. The privacy notice on the vendor's website refers to the GDPR; confirm that it also covers the product service.
