Legal basis

We process Personal Data in accordance with the Swiss Federal Data Protection Act (DSG) and the Ordinance to the Swiss Federal Data Protection Act (VDSG). In addition, we process Personal Data, if applicable, in accordance with the European General Data Protection Regulation (GDPR).


Personal Data: Any information relating to an identified or identifiable natural person. Data Subject: A person about whom Personal Data is processed. Edit: Any handling of Personal Data, regardless of the means and procedures used, in particular obtaining, storing, using, reprocessing, disclosing, archiving or destroying data.

Type, scope and purpose of data processing, data security

We process Personal Data that are necessary to carry out our activities in a user-friendly, secure, and reliable manner.

We process Personal Data for the period required for the respective purpose(s) or if required by law. Personal Data may be retained for the period during which claims may be brought against our company and to the extent that we are otherwise required to do so by law or legitimate business interests (e.g., for evidence and documentation purposes). As soon as your Personal Data are no longer required for the above-mentioned purposes, they will be deleted or anonymized as a matter of principle and to the extent possible. For operational data (e.g., system logs, logs), shorter retention periods of twelve months or less apply in principle.

As a matter of principle, we process Personal Data only with the consent of the Data Subject, unless the processing is permitted for other legal reasons, for example, to fulfill a contract with the Data Subject, to protect our overriding legitimate interests, because the processing is evident from the circumstances, or after prior information.

Processing of Personal Data

If you contact us to use WSL offers and services (e.g., by e-mail, telephone, etc.), the data you provide (e-mail address, possibly name, address and telephone number) will be stored by us. The communication of this information is on a voluntary basis and with your consent. Insofar as this involves information on communication channels (e-mail address, telephone number), you also consent to our contacting you via this communication channel. If you contact us via the online form, e-mail, telephone, we will forward the information you provide to the appropriate recipients so that they can respond to your inquiry and ask any follow-up questions. We do not use your information for any other purpose than in connection with the offers and services you have requested. No profiles will be created.

Transfer of Personal Data to third parties or abroad

We generally process Personal Data in Switzerland and the European Economic Area (EEA). However, we may also export or transfer Personal Data to other countries, in particular to process it or have it processed there, if the Federal Council has determined that the legislation of the country in question ensures adequate protection.

Rights of the Data Subjects

Data Subjects whose Personal Data we process have rights under Swiss data protection law. These include the right to information as well as the right to correction, deletion or blocking of the processed Personal Data.

You can object to the processing of your Personal Data in whole or in part at any time or revoke the consent you have given.

Data Subjects whose Personal Data we process also have a right of appeal to a competent supervisory authority. The supervisory authority for data protection in Switzerland is the Federal Data Protection and Information Commissioner (FDPIC).

Data security

We take appropriate technical and organizational measures (TOM) to ensure the protection of your Personal Data against unauthorized access and misuse.

Personal Data that you transmit to us via the website forms will be transmitted via a secure connection in encrypted form. The security procedure used (SSL-Secure Sockets Layer) corresponds to the usual state of technology. The access to the system takes place via an authorization procedure. SSL encryption (recognizable by https:// in the address bar of the browser) is a protocol for encrypting data during transmission from the web server to the browser. This transmission offers a particularly high level of security.

Use of the website

Server log files

Each time you access our website, we automatically collect information. This information, also referred to as server log files, is of a general nature and does not allow any conclusions about individual persons. Server log files are stored in the usual form: Calling IP address, date and time, page requested, data transmission protocol, response code of the server, origin of the request, browser, operating system. Without this data, it would not be technically possible to deliver and display the contents of the website. In this respect, the collection of this data is mandatory.

We evaluate these log file data records to further improve our website and make it more user-friendly, to find and correct errors more quickly and to control server capacities.

We also reserve the right to check the log files retrospectively if we suspect unlawful use of our offer.
