Provision and use of our website and online platform

Use for information
You can find out about Calenso and our range of services on the website without telling us who you are. As with any connection to a web server, the server on which we have the website and the online platform provided automatically logs and stores certain technical data and stores it for a short period of time. This includes the IP address and operating system of your device, the date and time of use and the type of browser you use to access the website or online platform.

We operate Calenso ("Online Platform"). When you register as a user on the Online Platform, we collect the information you provide to us. This includes general personal data such as name and contact details as well as personal information that you or other users enter, upload, generate, store and process when using the online platform.

Web analytics

We use web analysis services (currently Google Tag Manager, Google Analytics) to evaluate the use of the website and to obtain information for its optimization. The web analysis services we use collect and store usage data using cookies. Before they are transmitted to a server outside Switzerland/EU/EEA, the requesting IP addresses are truncated. We therefore do not transmit any personal data to the provider of the web analysis services abroad.

Advertising Technologies

We use advertising technologies from Google on the website. This allows us to target people who visit our website with advertising that is relevant to them when they visit other websites. The advertising materials are displayed on the websites you visit based on an analysis of your previous use of our website.

Resources from external websites

We integrate resources from external servers on our website. These contain visible content (Vimeo videos, YouTube videos, Calenso booking widget).

When you access these resources, the operator of the external server learns your IP address and/or certain marginal data that is necessary for the use of the external operator's server. Further information can be found in our transparency statement on the integration of third-party services.
