Stop Stalker Ads

Your personal data is being auctioned off to online advertisers through AdTech systems, putting profits over privacy.

Hands in the cookie jar

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 come under the hammer.

The General Data Protection Regulation (GDPR) 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.

How they steal your most intimate personal information

We want to end the widespread and systemic abuses of our privacy rights by the advertising industry.

Opt-out of Targeted Advertising on Meta

In March 2025 Meta settled a four year court case with human rights campaigner Tanya O’Carroll. She had taken legal action to force the social media giant to stop collecting and processing her personal data for advertising purposes. Meta have agreed to stop profiling Tanya – and now it’s your turn to say no to stalker ads!

If you use any Meta products – Facebook, Instagram, Meta Quest or VR, Threads or WhatsApp – you can use our tool to request that they no longer collect or process your data for advertising. Click the banner below.
