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.
We might have a one-way encrypted version of your email address.
One-way encryption means that a mathematical algorithm is used to ensure we can never recover your email address just from the encrypted version. This is called hashing, and the algorithm used is called SHA256. Everybody that runs the SHA256 algorithm on the same email address will get the same result.
For example, firstname.lastname@example.org always becomes the string:a2c4caafe8116ba323d051244ee6e647bce9b00b079b1bced7f94cd55276543f
We don’t store your actual email address, which is designed to protect you and your data.
We store information about which ads have been shown to you, and if you ignored them, clicked them or did something else. Remember, we don’t know your email address, only the one-way encrypted version of it, meaning the hash string.
We might set a cookie when you click an ad. This is done this way, so that we can get information back if you bought an advertised product, or signed up for an offer. We never use the cookie for anything else, and never will.
Not really a lot. We don’t share your data, and don’t know anything else about how you responded to the ads we showed you. We need core data to operate adserving for the publisher. To opt out of this, simply unsubscribe the newsletter you saw the ad in.
Your data is kept in our system for as long as we have a proven legal basis to process it on behalf of our advertisers, i.e. publishers, unless you opt out by unsubscribing the newsletter of the publisher or the legal ground for your data processing ceases to exist due to other reasons.
By law, you can ask us what information we hold about you, you can see it, and you can ask us to correct it if it is inaccurate. You can also ask for it to be erased and you can ask for us to give you a copy of the information. You can also ask us to stop using your information at any time, either by unsubscribing, or by emailing, writing or telephoning us using the contact details above.
If you have a complaint about our use of your information, you can contact the Danish Data Protection Agency (Datatilsynet) via their website or write to them at:
