Gmail Auto Dark Mode

Gives Gmail a dark theme automatically when your OS is in dark mode. Zero setup, no data collected, real-time switching.

Gmail Auto Dark Mode automatically applies a clean dark theme to Gmail whenever your OS is in dark mode, and reverts instantly when you switch back. Zero configuration, zero manual effort. KEY FEATURES * True Real-Time Switching: Automatically follows your system's light/dark schedule without needing a page reload. * Smart Color Preservation: Images, videos, avatars, and icons in emails are counter-inverted so they retain their natural colors rather than looking like photo negatives. * Full Companion App Support: Automatically styles Gmail's embedded side-panel apps (Google Calendar, Keep, Tasks, Contacts, and Chat). * Zero Clutter: No toolbar buttons, popup menus, or complicated settings. It just works. PRIVACY & SECURITY * 100% Local: Runs entirely in your browser with zero external network requests. * Zero Data Collection: Nothing is read, saved, tracked, or transmitted. Your emails and personal data remain completely private. * Open Source: Fully transparent and open-source on GitHub. FREQUENTLY ASKED QUESTIONS Why does Chrome say "Read and change your data on Google sites"? Chrome displays this standard warning for any extension that injects CSS stylesheets into a webpage to modify its appearance. The extension requires host access to Gmail and its embedded side-panel companion services (Calendar, Keep, Tasks, Chat) strictly to apply dark styling and counter-invert icons. It does not read your emails or access your account data. How do I toggle dark mode? Simply change your operating system theme: * macOS: System Settings -> Appearance -> Dark (or Auto) * Windows 10/11: Settings -> Personalization -> Colors -> Choose your mode: Dark * Linux (GNOME): Settings -> Appearance -> Dark NOTE: This extension is designed to work with Gmail's default theme. If you have a custom photo or color theme set in Gmail Settings -> Themes, please switch back to "Default" for the best experience.
