Each time the website is accessed, the following information is generally collected: the IP address, the browser's request, and the time of that request. In addition, the status and the amount of data transferred are recorded. Product and version information about the browser and operating system used are also collected, as well as the website from which access occurred.

Cookies are information files stored by the web browser on the user's computer. We use Borlabs Cookie to manage your consents; this stores a technically necessary cookie that remembers your cookie selection (no consent required for this cookie). Your consent decision is logged for evidentiary purposes. Further cookies are only set if you actively permit the relevant category (e.g. marketing, for the Meta Pixel); our traffic measurement tool (Matomo) operates without cookies. You can adjust or withdraw your consent at any time via the cookie settings and can generally restrict cookie storage in your browser.
For statistical analysis of website use, we use Matomo – an open-source analytics tool that we operate ourselves on our own server. No data is transmitted to third parties. Matomo is configured to operate without cookies and does not create a cross-device profile. Your IP address is shortened before storage (the last two octets are removed), so that it cannot be traced back to you personally; your browser's "Do Not Track" setting is respected. Due to this data-minimising configuration, traffic measurement is permitted without consent (Art. 6(1)(f) GDPR).
Where you consent via the cookie banner, we use the Meta Pixel provided by Meta Platforms Ireland Ltd. to measure the success of our advertising on Facebook/Instagram. This may involve data (including IP address, information about your visit, and cookie identifiers) being transmitted to Meta, potentially including transfer to the USA; Meta relies on the EU-U.S. Data Privacy Framework and/or Standard Contractual Clauses for this purpose. The Pixel is only loaded following your active consent. You can withdraw this consent at any time, with effect for the future, via the cookie settings (Art. 6(1)(a) GDPR).
For the display of the website, we use JavaScript/CSS libraries (Splide, GSAP, Lenis) loaded via the content delivery networks jsDelivr, Cloudflare (cdnjs) and unpkg. Your IP address is technically transmitted to the respective provider as a result, which may include transfer to the USA (Art. 6(1)(f) GDPR).
All information transmitted through use of the website is stored on servers within Switzerland/the European Union. As the transmission of information over the internet is generally not entirely secure, the security of data transmitted via the internet cannot be guaranteed. However, the website and other systems are protected by technical and organisational measures against loss, destruction, access, alteration or disclosure by unauthorised persons. Data is only transmitted to third parties and third countries within the scope of sections 4.4, 4.5 and 6.
Your personal data is not sold to third parties or passed on for their own purposes. Processing by third parties only takes place in the following cases:
Transfers to countries outside Switzerland/the EU only take place where an adequate level of data protection exists, or on the basis of suitable safeguards (e.g. the EU-U.S. Data Privacy Framework, Standard Contractual Clauses).
We reserve the right to amend this privacy policy at any time, with effect for the future. The current version is always available on the website. To stay informed of the applicable privacy policy, please check this website regularly.
You have the right to request information about the personal data processed — in particular the personal data itself, the purpose of processing, the retention period or the criteria used to determine it, the origin of the data, and any recipients or categories of recipients. You furthermore have the right to rectification, erasure and restriction of processing, to data portability, and the right to object to processing and to withdraw any consent given at any time, with effect for the future. To exercise these rights, please send a message to zug@gammacatering.com.
You also have the right to lodge a complaint with a supervisory authority – in Switzerland, with the Federal Data Protection and Information Commissioner (EDÖB, edoeb.admin.chedoeb.admin.ch); in the EU/EEA, with the data protection authority responsible for you.
