A consumer app that walks users through what their browser reveals in plain language (no jargon like 'Canvas fingerprinting' or 'AudioContext') and gives one-click protection matched to their threat model, whether basic, journalist, or high-risk.

Target user

Privacy-conscious internet users who don't know what browser fingerprinting surfaces actually do

Features
  • 'What does this site learn about me?' plain-language explainer for each visit
  • One-click protection profiles keyed to threat model (basic, journalist, high-risk)
  • Weekly privacy digest: 'this week, sites took X, Y, Z about you'
  • Family plan with shared device privacy scoring

Monetization
4/10

Feasibility
7/10
