időpontok: sovereignty score and 8 European alternatives

időpontok (idopontok.hu) is an online appointment and booking system designed for Hungarian businesses such as hair salons, dentists, lawyers, personal trainers, vets and car repair shops. Each business gets its own booking page. The system provides staff calendars, multiple locations, reminders by email and SMS, two-way Google Calendar sync, a customer database with booking history, online payments and deposits, cancellation rules and reports. A public marketplace lets clients find and book businesses. The service is delivered as a SaaS.

időpontok is a product of Verde Holding Kft., registered in Balatonalmádi, Hungary, and no foreign parent company is mentioned. According to its privacy notice, the application server runs on Fly.io, a US provider, in a data centre in Frankfurt. Cloudflare provides hosting, CDN and DDoS protection, and Vercel delivers the website; both are US companies. Transfers to the US rely on the EU-US Data Privacy Framework and/or standard contractual clauses. The software is not open source. The Hungarian company is therefore based in the EU, but its technical stack includes US service providers.

Why digital sovereignty matters with időpontok

időpontok is headquartered in HU 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 időpontok scores best on data residency.

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