What is the Meta Pixel and what is it used for?

The Meta Pixel is a code that you install on your website to track the actions of your visitors (purchases, forms, clicks). This data allows Meta to optimize your ads, measure your conversions, and create more effective audiences on Facebook and Instagram.

Is the Meta Pixel compliant with the FADP in Switzerland?

It can be, provided it is configured properly. In Switzerland, Art. 45c of the Telecommunications Act requires informing visitors about cookies and letting them refuse; the FADP requires transparency about the purposes and recipients of the data, Meta included. For EU visitors, the GDPR and the ePrivacy Directive require prior consent. In practice, the simplest approach is to fire the Pixel only after consent, through your CMP. Server-side tracking lets you control and limit the data sent to Meta, but it does not replace consent: a refusal is still a refusal.
