What is Client-Side Encryption?

Encryption happens in your browser. Not on a server.

Your data stays private. Even from the service provider.

No data sent over internet. Nothing to intercept.

Why It Matters

  • True privacy - No server sees your data
  • No data breaches - Nothing stored to steal
  • Compliance - GDPR and CCPA friendly
  • Trustless - Do not trust, verify

How It Works

You enter data in the browser.

Browser encrypts using Web Crypto API.

Only encrypted data leaves your device.

You hold the key. No one else can decrypt.
