To decide whether a page needs darkening, the content script reads colors that the page has already painted — the root background, the backgrounds behind text, and any dark-mode class the site sets on itself. It also measures the size and position of images and video so that they can be handed back their real colors.

All of this happens inside your browser, on the page you are already looking at. None of it is transmitted anywhere.

Two things are saved, both using Chrome's own extension storage: your on/off preferences (globally and per domain), and a small record of which domains were found to be light or dark, so repeat visits never flash.

Preferences use Chrome's synced storage, which means they follow your Chrome profile across your signed-in devices, under Google's terms rather than ours. The light/dark verdicts stay on the local device. Uninstalling the extension removes this data.

Subscriptions and the lifetime purchase are handled by ExtensionPay, which processes payment through Stripe. Your card details go to Stripe and are never seen by us or by the extension. What comes back is a yes-or-no answer about whether your copy is paid for.

We do not collect browsing history, page contents, keystrokes, form data, IP-based analytics, or any personal identifier. There is no account to create and no profile to build. Nothing is sold or shared, because nothing is gathered in the first place.

• Host access to all sites — the theme has to be able to apply on whichever site you turn it on for. The extension only acts on domains you have enabled.
• Storage — remembering your switches and the per-domain light/dark verdicts.
• Tabs — so the popup can tell which site you are currently on and label its per-site switch correctly.
