Just to reiterate in English: you’re asking why bunq, who values privacy very much, is using Facebook Pixels on it’s website properties.
TLDR; we only use the Facebook Pixel to track who visited bunq properties, we don’t send any details on who you are or what you did. For us it’s only a confirmation of interest, either to measure that you liked our content (or ad), or to prevent us from spamming you about stuff you’ve already seen before.
We currently use Facebook as a way to communicate with our fans, bunq users and potential bunq users. To tailor our content and ads we use Facebook’s tracking options to reach the right people and to prevent spamming everybody. We never send any user or visitor details to Facebook beyond ‘a someone visited one of our pages’. We only use the Facebook Pixels on our sites and none of the bunq sites have user sessions or data. In no way does Facebook have any access to your transactions or user data from the bunq side.
Absolute valid question and one I think would be very good to discuss and get bunqers’ honest feedback on (so let us know your opinions!).
