Dark Mode Toggle

Most popular dark mode extensions — the ones with millions of users — work by reading everything on the page: your emails, your banking details, the articles you read, the forms you fill out. They need to do this to recolor the page intelligently. When you install one of these extensions, you are granting a third party permanent access to everything you do in your browser. You are trusting that the developer will never sell your data, never get hacked, and never push a malicious update. That is a significant amount of trust to place in a free browser extension.

This extension does none of that. It applies a single CSS visual filter — the same kind used to turn a photo black and white — to the entire page. Your content never leaves your browser. There is nothing to collect, because nothing is read.

From a researcher's perspective, existing third-party dark mode extensions commonly require the following permissions:

tabs — access to all open tab URLs

webNavigation — ability to monitor every page you visit

host permissions — read/modify access to every website's DOM
