Zermelo is a Dutch software company that makes timetabling and scheduling software for schools. Its offer combines the software with services: an introductory demonstration, training for school staff, on-site implementation days and support while a school builds its first annual timetable. After roll-out, the company says it remains in contact with the school.
The operator is Zermelo Software B.V., with its head office in Leiden in the Netherlands. Its privacy statement names this company as controller for customers and website visitors. The statement says some work is outsourced to third parties under contracts, but the vendor's public pages do not name these parties, state where data is hosted, or name a parent company. A European school can therefore treat Zermelo as a Netherlands-based option, and should confirm the hosting location and sub-processors in the processing agreement before use.
