Your Browser is Leaking: A Guide to Fingerprinting

SnapSend Team

Most people think preventing tracking is as simple as "clearing cookies" or using Incognito mode. Unfortunately, ad-tech companies have evolved.

Enter Browser Fingerprinting.

How It Works

When you visit a website, your browser hands over a lot of information to ensure the page renders correctly:

  • Screen resolution
  • Operating system version
  • Installed fonts
  • Audio hardware details
  • Battery status

Individually, these are innocent. Collectively, they form a unique "fingerprint." The combination of Chrome v120 + Linux + 1920x1080 + specific list of installed fonts might only apply to one person in millions. That person is you.

Defending Against Fingerprinting

1. Resist "Unique" Configurations

The more you customize your browser (custom themes, rare plugins), the more unique you look. Using a standard, stock browser makes you blend in with the herd.

2. Use Privacy-Focused Browsers

Browsers like Firefox (with "Resist Fingerprinting" enabled) or Brave are designed to return generic values. They lie to websites, saying "I am just a generic Windows PC with standard fonts," even if you aren't.

3. Disable Javascript (Nuclear Option)

Most fingerprinting relies on Javascript. Disabling it breaks most websites, but for pure reading, it offers the highest anonymity.

4. Ephemeral Sharing

When sharing sensitive links, don't use platforms that build profiles on who you share with. Snapsend is built to be a "Zero Knowledge" platform. We don't track your user agent for analytics, we don't fingerprint machines, and we delete access logs. We connect A to B, then vanish.
