Overview

What does etermio do?

What is etermio

etermio is a German online appointment scheduling and customer engagement service. It lets visitors book a meeting, a demonstration or a service slot directly from a website through an embeddable booking widget. The widget loads JavaScript from etermio servers and exchanges data such as available slots, contact details and the booking confirmation.

Cookies and data collected

When the widget loads, etermio sets first party cookies such as etermio_session for the booking session and _et_user_id for visitor identification. It also stores values in localStorage. Personal data processed includes the booker name, email address, telephone number, chosen time slot and any free text comment.

GDPR and ePrivacy legal basis

The actual booking is processed on the basis of Article 6(1)(b) GDPR, since the booking is a pre contractual or contractual measure requested by the data subject. The loading of the widget and the storage of cookies on the device require consent under Article 5(3) of the ePrivacy Directive and Section 25(1) TTDSG in Germany.

Data transfers and hosting

etermio is hosted in Germany and processes personal data inside the European Economic Area. There is normally no systematic transfer of booking data to third countries. Controllers should still document the processor relationship in a written agreement under Article 28 GDPR.

DPIA considerations

A formal DPIA is not generally required for low risk appointment scheduling. When the booking flow handles health, legal or other sensitive subject matter, a DPIA under Article 35 GDPR is recommended, with a focus on retention, access controls and minimization of free text fields.

Compliance steps

Block the etermio widget until consent is collected, list etermio in the privacy notice and the cookie banner, sign a data processing agreement with the provider, document retention of booking records and configure the widget to capture only the data fields strictly needed.

Compliance

etermio and the GDPR

etermio is classified as “Preferences”. On a site that targets European visitors, it must only load after the visitor consents, and it must be listed in your cookie policy.

Legal basis
Article 6(1)(b) GDPR (performance of a contract or pre contractual measures) for the actual booking, combined with Article 6(1)(a) GDPR (consent) for the loading of the embedded widget and its cookies under Section 25(1) TTDSG and Article 5(3) ePrivacy Directive.
Risk level
medium
Applicable regulations
GDPR, ePrivacy Directive, TTDSG, BDSG, LOPDGDD, CNIL guidelines, EDPB guidelines on consent

Impact assessment (DPIA)

A DPIA is not strictly required for a standard appointment widget, but a record of processing activities should describe data collected (name, email, phone, appointment details), the legal basis, retention and the role of etermio as processor. Where sensitive categories (for example health appointments) are booked, a full DPIA under Article 35 GDPR is recommended.

How should etermio be implemented correctly?
