Platforms like Pricefx, Revionics and Criteo adjust prices in real time based on what they've inferred about your willingness to pay.
A/B Testing Platforms
Optimizely, Adobe Target and Dynamic Yield show different prices and offers to different users based on behavioural profiles built without your knowledge.
Data Brokers
Acxiom, LiveRamp and Oracle Data Cloud compile detailed profiles of you and sell them to retailers, insurers and advertisers to inform pricing decisions.
Cross-site Trackers
Facebook, Google and hundreds of other companies follow you across every app and website you use, building a profile of your behaviour and interests.
Device Telemetry
Your phone's manufacturer and apps constantly send usage data about how you use your device. fairer blocks the endpoints they report to.
Social Media Trackers
Facebook, Twitter and LinkedIn embed invisible trackers on millions of websites — following you even when you're not using their platforms.
How it works
Protection at the deepest level
01
Intercepts at DNS level
Every app on your phone makes DNS requests before loading content. fairer intercepts these requests before any data is exchanged.
02
Checks against 400k domains
Known commercial manipulation and tracking domains are blocked instantly. Everything else passes through normally.
03
Encrypts your DNS queries
Allowed queries are forwarded via DNS-over-HTTPS, preventing your ISP from seeing which websites you visit.
04
Works across every app
Unlike browser extensions, fairer protects every app on your phone — including shopping apps that do the most aggressive tracking.
