Invisible - Privacy Policy

Last updated: 2026-08-25

The short version

Invisible collects nothing. It sends nothing. Everything stays in your browser.

What Invisible does

Invisible injects custom HTTP headers into outgoing requests for domains you configure. That is all it does. Headers are added locally by the browser engine before the request leaves your machine.

Data collection

None. Invisible does not collect, store, or transmit any personal data. There is no account, no registration, no usage tracking.

Network activity

Zero. Invisible never connects to any external server. There is no telemetry, no analytics, no update ping, no phone-home behavior of any kind. The extension is 100% offline.

Permissions

Invisible requests only the permissions required to modify HTTP headers:

  • declarativeNetRequest: to inject headers into outgoing requests on domains you specify
  • storage: to save your rules and profiles locally in your browser

That is the complete list. No access to page content, browsing history, or tabs.

Where your data lives

Your header rules, domain configurations, and named profiles are stored locally in chrome.storage.local. This data never leaves your device. If you uninstall the extension, this data is deleted automatically by Chrome.

Third-party services

None. Invisible has zero external dependencies at runtime. No CDN, no API, no cloud service.

Cookies and tracking

Invisible does not use cookies and does not track you in any way.

Supported browsers

Invisible works on Chrome, Edge, and Brave. This privacy policy applies equally to all supported browsers.

Changes to this policy

Any changes will be reflected in extension updates. The date at the top of this page will be updated accordingly.
