Transparent handling of personal data is very important to us. This Privacy Policy explains which personal data we collect, for what purposes we process it, and to whom we may disclose it. We regularly review and update this Privacy Policy to ensure the highest level of transparency.
We process general personal data. Personal data refers to any information relating to an identified or identifiable natural person. A person is considered identifiable if their identity can be inferred from available information.
Example: Your name, IP address, and residential address are considered personal data.
You often provide your personal data directly to us. Whenever you enter and submit your personal data, it is considered voluntarily provided to us. Providing data is generally voluntary, but may be required to use certain services.
Example: You enter your details in a contact form or sign up for a newsletter.
When you use our services, we may collect data automatically without your active input. This typically includes device information and usage data.
Example: We collect information about the operating system of the device used to access our website.
We continuously strive to improve our services. For this purpose, we use your personal data to develop and enhance our products and services.
Example: We analyze website usage data to continuously improve usability.
We may share your personal data with companies that independently decide how they use the data. This typically occurs when required by law, when outstanding claims are transferred to debt collection agencies, or to detect fraudulent activity.
Example: A legal requirement obliges us to share your data with a public authority.
We work with service providers located around the world. This allows us to access the best and most reliable services globally. In some cases, data may be transferred to countries that do not provide the same level of data protection as Switzerland.
Example: We use a cloud provider such as Google, headquartered in the United States.
We use Google Analytics, a web analytics service provided by Google Ireland Ltd., Google Building Gordon House, Barrow Street, Dublin 4, Ireland, and Google LLC, 1600 Amphitheatre Parkway, Mountain View, CA 94043, USA (together “Google”).
What data is processed?
Google Analytics collects information about website usage, including:
IP address
Technical information (browser, operating system, screen resolution)
Website interactions
Duration of visit
Date and time of access
Referrer URL
IP addresses are anonymized so that personal identification is no longer possible. When a user visits our website for the first time, Google Analytics may generate an identifier to recognize returning visitors. If you are logged into a Google account, cross-device tracking may occur.
Purpose of processing
We use IP addresses to estimate approximate location and measure regional relevance of our services. Technical data ensures proper website display across devices. Interaction and usage data help us analyze and optimize marketing campaigns and user experience. Referrer data is used to evaluate the effectiveness of marketing channels.
Data sharing
Data may be transferred globally by Google, including to the United States, where data protection laws may not provide an equivalent level of protection.
We use Google Tag Manager, provided by Google Ireland Ltd. and Google LLC.
Google Tag Manager allows us to manage tracking tools such as Google Analytics, Facebook Pixel, and Hotjar centrally. Google Tag Manager itself does not collect personal data. Data is collected by the integrated tools.
We use PrivacyBee, a service provided by PrivacyBee AG, Laupenstrasse 1, 3008 Bern, Switzerland.
What data is processed?
IP address
Browser type and version
Operating system
Date and time of access to the privacy policy
Purpose of processing
These data are used to correctly display the privacy policy and ensure it remains up to date and compatible with the user’s device.
Data sharing
Data remains with PrivacyBee and is not shared further.
