Privacy Policy — Caesar Cipher Decoder

Last updated: April 2026

This extension collects, transmits, and stores NOTHING. Here's what that means in practice:

What we don't collect

• No personal information
• No browsing history
• No selected text (text you right-click stays in your browser)
• No usage analytics or telemetry
• No cookies, no IP addresses, no device fingerprints

What the extension does

When you right-click selected text and choose "Decode as Caesar Cipher":
1. The text is passed locally to a result page bundled inside the extension.
2. The result page computes all 26 Caesar shifts client-side using pure JavaScript (lib/caesar.js in the source code).
3. Nothing is sent over the network. Nothing is saved to disk or storage.

Permissions

The extension requests one permission only: contextMenus — used to register the "Decode as Caesar Cipher" right-click menu item. No other permissions are requested.

Third parties

None. The extension makes zero network requests and has no third-party dependencies at runtime.
