Stop Stalker Ads
Your personal data is being auctioned off to online advertisers through Adtech systems, putting profits over privacy.

How the Adtech Industry Works
Companies use Real-Time Bidding systems to gain access to your data for targeted advertising. From highest to lowest bidder, your data is harvested and combined with other datasets to build a profile about you, even if the company doesn’t win the bid to show you their advert. Everything from your geolocation, political beliefs and sexual preferences to your browsing habits and information about your devices comes under the hammer.
Data protection law grants individuals powerful data rights, including the right to retrieve, delete or revoke consent for the personal data companies hold. When RTB systems broadcast your personal data to thousands of faceless companies, your data rights become impossible to use.
