GUIDE Exposure concepts behind your scan

Privacy Exposure Guide

Understand what exposure means, why it happens, and what actually helps reduce it.

This page explains the concepts behind the scan. Your downloadable PDF contains your specific results.

Device Identifiability

Surface
#

What it means

How unique your browser and device look when visible traits are combined. Even common settings become identifying when they stay stable over time.

What increases it

  • Stable screen size, scaling, and color depth
  • Hardware hints such as CPU cores and memory
  • Language, locale, and timezone combinations
  • Highly customized browser configurations

What actually helps

  • Keep extensions minimal and purposeful
  • Use separate browser profiles for different contexts
  • Enable built-in anti-fingerprinting features where available
  • Prefer consistency over constant tweaks

Common myths

  • Incognito mode makes me anonymous
  • More extensions always means more privacy
  • Changing one setting fixes fingerprinting

Tracking Surface

Surface
#

What it means

How easily tracking can persist via cookies, storage, and browser state across sessions.

What increases it

  • Third-party cookies
  • Persistent storage such as localStorage and IndexedDB
  • Always-on login sessions
  • Embedded third-party scripts

What actually helps

  • Block third-party cookies
  • Enable built-in tracking protection
  • Clear site data for high-tracking domains
  • Avoid staying logged in everywhere by default

Common myths

  • Private browsing blocks tracking
  • Ad blockers stop all tracking
  • Clearing cookies once is enough

Permission Surface

Surface
#

What it means

How much permission-based access is available or easy to grant to websites over time.

What increases it

  • Granting permissions reactively
  • Leaving unused permissions active
  • Allowing notifications across many sites
  • Camera, microphone, or location set to allow

What actually helps

  • Review site permissions periodically
  • Set sensitive permissions to Ask
  • Block notifications by default
  • Revoke anything non-essential

Common myths

  • If I don’t use it, it doesn’t matter
  • Permissions expire automatically
  • One trusted site can’t increase risk

What helps vs what doesn’t

Summary
#

What helps

  • Fewer, well-chosen protection layers
  • Separation between browsing contexts
  • Intentional, consistent configuration
  • Understanding trade-offs instead of chasing absolutes

What doesn’t

  • Privacy theater and one-click promises
  • Random extensions and tweaks
  • Chasing perfect scores
  • Adding complexity without understanding

How to use your results

Guide
#

Your scores are relative indicators, not proof of identity or real-world risk by themselves. Use them to compare surfaces, find where exposure concentrates, and decide where effort is worth it.

  • Compare surfaces, not yourself
  • Focus on patterns over time
  • Prioritize the simplest changes that matter
