Bookwhen: sovereignty score and 8 European alternatives

Bookwhen is an online booking system that lets organisers schedule and sell places at classes, courses, workshops, events and activities. Organisers publish a hosted booking page, share it by link or embed the booking form in their own website, and receive automated confirmations, reminders and waiting lists. The service is delivered online and a public API is documented.

The data controller named in the privacy policy is Bookwhen Ltd, registered at Belsyre Court in Oxford, England, so the vendor is British and not established in the EU. The policy states that data may be stored and processed in any country where the company operates. Its sub-processor list places Google cloud hosting in the United Kingdom and United States, backups at Amazon Web Services in the EU, and US-based suppliers for several functions. The policy refers to EU and UK data protection law and names an EU representative under GDPR Article 27. The software is not open source, so European organisations should review the sub-processor locations and the data processing agreement before use.

Why digital sovereignty matters with Bookwhen

Bookwhen is headquartered in GB, outside the EU. Contracts and data therefore also fall under non-European law. The GDPR applies through contractual terms, but in a conflict with local legislation you have less certainty than with a European vendor.

Bookwhen hosts data in OTHER, US, EU. Exactly what stays within the EU — and what does not — is defined by the vendor's data processing agreement and sub-processor list, not by a setting you control yourself; check those documents for the precise scope, including backups, logs and support access.

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