Why this matters for digital sovereignty
Booking systems process customer contact details and appointment information, which falls under GDPR and becomes more sensitive when appointments concern medical or personal matters. Check where the data is stored, whether a data processing agreement with EU hosting is available, and how easily calendar and customer data can be exported.
