Reservio: sovereignty score and 8 European alternatives

Reservio is booking and appointment software for small service businesses such as hair salons, yoga studios, wellness centres, gyms and medical clinics. It includes a calendar, online booking through a booking page, link or form, SMS and email reminders, client and team management, online payments and a point-of-sale system. It is delivered as a web service, with the Reservio Business app for Android and iOS and an option for a branded app.

Reservio, s.r.o. is based in Brno, Czech Republic, and is a member of the ABUGO Group. According to its privacy policy, all data is held on servers in the European Union or in countries with equivalent protection. The policy also names two US-based processors, Twilio (SendGrid) and OpenAI, that receive personal data. The software is not open source. For a European organisation this means a vendor under EU law with EU hosting, where the named US sub-processors deserve attention in the data processing agreement.

Why digital sovereignty matters with Reservio

Reservio is headquartered in CZ and therefore falls under European law: the GDPR, NIS2 and the Data Act. No foreign legislation can compel access to your data.

Data is hosted exclusively in the EU, so Reservio scores best on data residency.

Reservio 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 Reservio together with your other vendors and gives a total score, a heatmap and the main risk drivers.
