We have extensive data protection and data processing agreements with everybody who uses our technology, protecting your data from third parties illegal access. We do not look at your data, do not share it with anybody. It belongs to you and a publisher that sent you an email. The publisher might use it to target ads towards you. If you clicked on a car ad, you might see more car ads on the basis of this click. If you responded poorly to an Ads about shampoo, you might see less shampoo Ads in the future. If advertiser Y have access to your email address (because you are a client of theirs now or you were at some point) they can use the Passendo platform to show you specific ads. The advertiser will never get access to any data about you specifically in any way.
