The purpose of this on-line tool is to provide you with control over your personal data within mediasmart's "Bsmart" demand side advertising platform.

mediasmart provides advertisers with an on-line platform by which they bid on the opportunity of serving advertisements to users of (mostly free) mobile applications such as games, etc.

What this means is that, should you download an application that uses advertisements within its business model, and should such application be connected to on-line exchanges with whom we may work with, chances are that advertisements served through such application might have come from one of our clients.

While mediasmart does not process by itself any personal data from end-users of such mobile applications, our Clients might do so by using our on-line platform.

You may use this first form to opt-out of any collection and usage of data for interest-based advertising on mobile devices. (If you would only like to check whether your information may be already being processed by any of our clients using our software as a service platform, please refer to the second form below.)

This tool uses your mobile device universally unique identifier (UUID) in order to provide you with these abilities. The form below allows for UUID such as Apple IDFA or Google Advertising Identifier. You may also leave empty the fields below when you are connected via WiFi in order to query about your current ip address.

Please use this link if you need help to find out your mobile device universally unique identifier (UUID).


Please note that if you enter the UUID on your mobile device and click on Opt-Out, such UUID will NOT be served advertising based on interests any more. You will continue to see advertising, but it may be less relevant.

If you are visiting this site using a WiFi connection, leave the form field empty and click on Opt-out, we will read the IP address from which you are sending the request. That is the IP address that will be added to our Opt-out list. Please take into account that if you are sharing your WiFi with other people (for example, your co-workers at an office) this will affect all of the users using that IP address as well.

We will not process any IP addresses that come from cellular connections, as these are always shared by a lot of users, therefore, if you are accessing from your phone or tablet via a 3G or 4G connection, please provide your user identifier.

By using the form below, you can may check whether your UUID is already being processed by any of our clients using our software as a service platform.

(Please kindly note that this second form ONLY checks whether your UUID is already within the system and does NOT opt-out from it. To opt-out please use the first form above.)
