Calenso is an appointment booking and scheduling platform that lets businesses offer online appointment booking, smart calendars and queue management. Its booking widget sets cookies for session handling and to attribute bookings, and it processes appointment and customer data in Switzerland and the EU. Under the GDPR and the ePrivacy Directive, its non essential cookies require prior consent.
Calenso is a Swiss appointment booking and scheduling platform used by businesses to let customers book appointments online, manage smart calendars, run queue and event booking and synchronise staff availability. Its booking widget is embedded on a website so visitors can select a service, a time slot and provide their details.
When the Calenso booking widget loads it sets cookies for session handling and, depending on configuration, to attribute bookings and measure usage. To process an appointment it handles customer data such as name, contact details, the chosen service and time, and any information the customer adds. Some cookies are persistent identifiers used for analytics.
The analytics and attribution cookies are not strictly necessary, so storing them is governed by Article 5(3) of the ePrivacy Directive and requires consent, while a cookie strictly needed to hold an appointment in progress may be exempt. The customer appointment data is personal data under the GDPR, processed for the booking.

Calenso is a Swiss company and processes data in Switzerland and the European Union. Switzerland benefits from a European Commission adequacy decision, so transfers from the EU are permitted without additional safeguards such as Standard Contractual Clauses, although you should record them. Confirm the data region offered by your plan.
List the Calenso cookies and domains in your cookie policy and gate the non essential ones behind consent. Sign a data processing agreement, define retention for appointment data, and confirm whether data stays in the EU or Switzerland.

Websites using Calenso must obtain user consent under GDPR regulations.
DPIA considerations
Calenso sets cookies and processes customer data such as name, contact details, the chosen service and time. Key DPIA considerations: (1) analytics and attribution cookies are not strictly necessary identifiers requiring consent; (2) a cookie strictly needed for an appointment in progress may be exempt; (3) data is processed in Switzerland and the EU, with Switzerland benefiting from an adequacy decision; (4) appropriate retention must be set. A DPIA is advisable for sensitive services such as healthcare.

Calenso sets cookies for session handling and, depending on configuration, to attribute bookings and measure usage. A cookie strictly needed to hold an appointment in progress may be essential, but the analytics and attribution cookies are not strictly necessary and require consent.
Yes for the non essential cookies. The analytics and attribution cookies Calenso sets need prior consent under the GDPR and the ePrivacy Directive, so they should not load until the visitor accepts. A cookie strictly necessary to complete an appointment can rely on a different basis.
Consent under Article 6(1)(a) GDPR covers the analytics and attribution cookies, while processing the appointment the customer requested relies on contract under Article 6(1)(b). Appointment data should be kept only as long as needed for the service and any legal obligations.
Calenso processes data in Switzerland and the EU. Switzerland has an EU adequacy decision, so transfers from the EU are permitted without extra safeguards, but you should document them and confirm that no processing occurs in a country without adequacy.
A DPIA is usually not mandatory for a standard appointment scheduler, but it is advisable if you book sensitive services, such as healthcare, where appointment data may reveal special categories. Documenting the processing, the cookies and the retention supports accountability.
Add Calenso through a CMP that blocks non essential cookies until consent, keep any essential appointment cookie separate, and confirm whether data stays in the EU or Switzerland. Sign a data processing agreement, set retention, and disclose cookies and recipients.
Other appointment booking tools include Calendly, Cal.com, SimplyBook.me and Acuity Scheduling, some of which process data in the EU. All set booking and analytics cookies and process customer data, so consent gating and clear retention remain the priority.
Describe the Calenso cookies, their purpose and duration, list the Calenso domains, and state that appointment data is processed in Switzerland and the EU under an adequacy decision. Explain the booking process and retention in your privacy notice and keep both aligned with the integration.
