Privacy Policy
What is this privacy policy about?
Jan Stelcl Ingenieur GmbH collects and processes personal data concerning you or other individuals (so-called "third parties"). Here, we use the term "data" synonymously with "personal data."
In this privacy policy, we describe what we do with your data when you use the js-ing.ch website (hereinafter collectively referred to as the "Website"), obtain our services, otherwise interact with us within the scope of a contract, communicate with us, or deal with us in any other way. Where appropriate, we will inform you via timely written notice of additional processing activities not mentioned in this privacy policy. Additionally, we may inform you separately about the processing of your data, for example, in declarations of consent, contractual terms, supplementary privacy policies, forms, and notices.
If you transmit or disclose data to us regarding other individuals—such as family members, colleagues, etc.—we assume that you are authorized to do so and that the data is accurate. By transmitting data concerning third parties, you confirm this. Please also ensure that these third parties have been informed about this privacy policy.
This privacy policy is designed to meet the requirements of the EU General Data Protection Regulation ("GDPR"), the Swiss Data Protection Act ("DPA"), and the revised Swiss Data Protection Act ("revDPA"). However, whether and to what extent these laws apply depends on the specific case.

What data do we process?
We collect information you transmit to us when you contact us or order services. This includes general personal data, such as your name and contact details, as well as—where applicable—information regarding your position or role within the organization on whose behalf you are contacting us. If you order paid services, we also request financial data, such as your preferred payment method and billing address. We also process personal data received from third parties. This typically includes personal data obtained during correspondence or meetings with clients or business partners—for example, your name and details regarding your role as a team member of the client or business partner. To the extent necessary to achieve the purposes described in this privacy policy, we also collect general personal data from publicly accessible registers, websites, or platforms (e.g., to verify your signing authority) or by obtaining information from third parties (e.g., for reference checks during the application process, provided you consent).
For what purposes do we process your data?
Use for informational purposes
You can find out about Jan Stelcl Ingenieur and our range of services on the website without disclosing your identity. As with any connection to a web server, the server hosting our website automatically logs and stores certain technical data for a short period. This includes your device's IP address and operating system, the date and time of use, and the type of browser used to access the website. Web Analytics
We use web analytics services (currently Google Analytics) to evaluate website usage and gather information for its optimization. The web analytics services we use collect and store usage data via cookies. Requesting IP addresses are truncated before being transmitted to a server outside Switzerland, the EU, or the EEA. Consequently, we transmit only anonymized personal data to the web analytics service provider located abroad.
Resources from External Websites
We embed resources from external servers on our website. These include visible content (images, videos) as well as technical resources (fonts, scripts). Technical resources are used to improve our website's performance or security. When these resources are accessed, the operator of the external server receives your IP address and/or certain metadata necessary for using the external operator's servers.
Note on the Use of Cookies
We use cookies, tags, and similar technologies on the website, in order to provide you with the best possible user experience and to help us improve the website. Cookies are text files that are downloaded to your computer or mobile device when you visit a website or use an app. Some of the cookies we use are necessary to provide specific website functions. In addition, we use cookies to analyze website usage and to obtain information for optimizing the website. Unless technically necessary, we only use analytics cookies with your active consent. You have the option to accept or reject them (via the cookie banner). You can configure your browser not to accept cookies or to prompt you before a cookie is set. You can also delete cookies from your device using your browser's corresponding function.

Where is your personal data processed?
We primarily store and process your personal data in Switzerland and the EU. However, we may also transfer your personal data to recipients in countries outside Switzerland or the EU (worldwide). We carry out data transfers to countries without adequate data protection based on standard data protection clauses or statutory exceptions (e.g., necessity for the performance of a contract).
Please also note that data exchanged via the Internet is frequently routed through third countries. Your data may therefore be transferred abroad even if the sender and recipient are located in the same country.
How long do we process your data?
We process your data for as long as required by our processing purposes, statutory retention periods, and our legitimate interests in processing for documentation and evidentiary purposes, or for as long as storage is technically necessary.

You have the following rights regarding personal data concerning you:
• The right to request information from us as to whether and which data concerning you we are processing;
• the right to have data corrected if it is incorrect;
• the right to request the deletion of data;
• the right to request that we provide certain personal data in a common electronic format or transfer it to another controller;
• the right to withdraw consent, insofar as our processing is based on your consent;
• the right to obtain, upon request, further information necessary for the exercise of these rights. This privacy policy does not form part of any contract with you. We may amend this privacy policy at any time. The version published on this website is the current version.
