Privacy Policy — Dev Dark Mode Toggle

Last updated: 8 July 2026

Dev Dark Mode Toggle is designed to do one thing: emulate the CSS prefers-color-scheme media feature on the tab you choose. It is built to handle no personal data.

Data we collect

None. The extension does not collect, store, transmit, sell, or share any user data of any kind. Specifically:

• No browsing history, page content, URLs, or form data are read or stored.
• No analytics, telemetry, tracking, or advertising.
• No remote servers are contacted. All processing happens locally in your browser.

What the extension does with permissions

• debugger: used only to send the DevTools Protocol command Emulation.setEmulatedMedia (and a single matchMedia read to detect your system scheme) to the tab you explicitly toggle. It attaches only on toggle and detaches when you toggle back. No page content is inspected, captured, or transmitted.
• offscreen: used only to read your browser's current color scheme via matchMedia, so the toolbar icon matches your theme. Nothing is stored.

Storage

The only state the extension keeps is a short-lived, in-memory note of which tabs currently have a scheme forced. This is never written to disk and is discarded when the tab closes, when you toggle it off, or when the browser restarts.

Changes

If this policy changes, the "Last updated" date above will change accordingly.
