Why Night Owl works on every page
Dark mode has to reach each page as it opens, so Night Owl runs on all sites. Chrome describes this as "Read and change all your data on all websites" when you add it. All Night Owl does there is add a color filter, and its code makes no network requests, so nothing about the pages you visit leaves your browser.

Questions
Something else? Contact Tech How.
Which browsers does it work in?
Chrome, Edge, Brave and Opera on a computer, installed from the Chrome Web Store. It is not available for Firefox or Safari, and phones do not support browser extensions.
Does Night Owl work on every website?
It applies the same filter to every page. Sites that already have their own dark theme can look light when filtered twice; switch Night Owl off on those.
Why does Night Owl need access to all websites?
So dark mode is applied to every page as it opens. Chrome uses the same wording for any extension that changes how pages look. Night Owl only adds a color filter and sends nothing anywhere.
Can I use it on my phone?
No. Chrome on Android and iPhone does not support extensions. Use your phone's own dark mode instead.
How do I remove it?
Right-click the Night Owl icon and choose Remove from Chrome.
