Flowin: sovereignty score and 8 European alternatives

Flowin is a cloud platform for ski schools, boating schools, alpine schools and other outdoor providers. It combines online booking, activity and staff planning, and time recording in one system. Providers define their offers and pricing rules once, sell them through an integrated webshop or a widget on their own website, and add extras, vouchers and on-site bookings. Guides see their assignments, participant lists and payment status in a smartphone app, maintain their availability and record attendance on site. Flowin is delivered as software as a service.

Flowin is developed and operated by Solved Development GmbH in Bern, Switzerland. Switzerland is not in the EU but is an EFTA country with an EU adequacy decision. The privacy policy refers to the Swiss data protection act and the GDPR, and states that end-customer booking data is processed on behalf of the providers. The site does not say where data is hosted, so ask the vendor. It names no parent company.

Why digital sovereignty matters with Flowin

Flowin is headquartered in Switzerland and falls under Swiss law, including the revised Swiss data protection act. Switzerland is not an EU member, but the European Commission recognises its level of data protection as adequate. Its Swiss headquarters does not by itself bring it under US legislation such as the CLOUD Act.

Flowin hosts data in Switzerland only. Switzerland is not part of the EU or the EEA, so the GDPR does not apply there directly; the European Commission does recognise Swiss data protection as adequate, so personal data can go there without extra safeguards. Our model therefore scores it between EU hosting and hosting outside Europe. If you require strictly EU hosting, take this into account.

Flowin is closed source and hosted by the vendor. The encryption keys and the runtime sit with the vendor and switching requires data migration. Ask about bring-your-own-key, export options and open standards.

What this means for your organisation depends on your whole stack and context. The free assessment weighs Flowin together with your other vendors and gives a total score, a heatmap and the main risk drivers.
