FixableWho's tracking you online

Cross-site tracking

Cookies, pixels and fingerprinting that follow you from site to site.

Understand it

Most of the web quietly watches where you go. Cookies and tracking pixels tag you on one site and recognise you on the next; “fingerprinting” identifies your device from its settings even when you clear cookies. The profile built this way - what you read, buy and search - is bought and sold, and feeds the data brokers.

How to spot it

Adverts that “follow you around” after you look at something once are the visible tip of it.

Close the gap

  1. Use a tracker-blocking browser extension such as uBlock Origin.
  2. Choose a browser that blocks third-party cookies and fingerprinting by default.
  3. Reject non-essential cookies - UK sites must offer you the choice.
  4. A filtering DNS blocks many trackers across every app on the device.

What to do about it

This is part of your plan - Switch to a browser that tracks you less. Work through it there and you’ll close this off along with everything else it covers.
