Eclipse · Dark Mode for Safari
Help getting Eclipse running, answers to common questions, and a plain-English account of what Eclipse does with your data — which is nothing.
Eclipse is made by one developer, and every message is read personally. Whether it's a bug, a site that won't theme correctly, a feature idea, or just a question — get in touch and you'll hear back.
When reporting a problem, it helps to include:
Open Safari → Settings → Extensions and tick Eclipse Extension. Then click the Eclipse button in Safari's toolbar and grant it permission to run on the websites you want. The toolbar popup is your control panel — flip Eclipse on and start browsing.
Make sure the extension is enabled in Safari → Settings → Extensions. If it's enabled but hidden, choose View → Customize Toolbar in Safari and drag the Eclipse button onto the toolbar. The companion Mac app also shows the live extension status and a step-by-step enable guide.
Eclipse recolors the colors a page actually declares in its CSS, rather than blanket-inverting the screen — that's what keeps photos, videos, and logos looking right. A handful of sites load styles from servers that block Eclipse from reading them, which can leave small areas unthemed. If you hit a stubborn page, email it to us and we'll take a look.
Yes. Eclipse never puts a filter over the page, so photos, video, and artwork paint at their true colors. Only declared interface colors — backgrounds, text, borders — get remapped into a dark palette, with hue preserved (blue stays blue, red stays red).
No. Eclipse detects sites that already ship a dark theme and leaves them alone rather than recoloring them twice. You can also scope where Eclipse runs from the popup: all sites, only sites you list, or every site except the ones you list.
Yes — the toolbar popup includes adjustments for brightness, contrast, and tone, plus mode and automation (follow the system appearance or a schedule). Everything is controlled from the popup; the changes apply instantly across your open tabs.
Eclipse is a macOS Safari extension today. If you'd like to see it on iOS, let us know — interest helps us prioritize.
Eclipse is built to do one job — make websites comfortable to read in the dark — and it does that entirely on your Mac. There is no account, no analytics, no tracking, and no server that your browsing is ever sent to.
Your preferences — whether Eclipse is on, your adjustments, your per-site list, and automation choices — are saved locally on your device using Safari's extension storage. They never leave your Mac and are not shared with us or anyone else.
To theme a page, Eclipse reads that page's own styles in your browser and writes an override that maps its colors into a dark palette. In some cases it requests a page's external stylesheet so it can read the colors defined there. This all happens on your device, in the moment, to render the page — the contents of the pages you visit are never recorded, transmitted, or stored by Eclipse.
Eclipse contains no advertising SDKs, no analytics frameworks, and no third-party trackers. It makes no network connections of its own beyond fetching a page's stylesheet (as described above) to theme what you're already viewing.
If you email us, we receive whatever you choose to send — your message, your email address, and any details or screenshots you include. We use that information only to respond to and resolve your request, and we don't share it with anyone. You can ask us to delete your correspondence at any time.
Eclipse is not directed at children and collects no personal information from anyone.
If this policy ever changes, we'll update this page and revise the date below. Material changes will be reflected here.
