A single master toggle darkens every site you visit. Works on document_start for zero flicker, even on JavaScript-heavy SPAs.
Default, Warm, Blue, and AMOLED. Each tuned to reduce eye strain in different environments.
Set custom time windows or let it auto-detect sunrise/sunset from your location — fully offline, no API needed.
Override the global setting for specific domains. Exclude sites or set custom appearance per-domain.
Brightness, contrast, sepia tint, and font color — all individually adjustable with live preview sliders.
All settings stored locally on your device. No user tracking, no analytics, no backend servers. Open architecture.
Each theme is carefully crafted to reduce eye strain in different conditions.
Cool neutral dark — the universal choice. Works perfectly on coding, reading, and productivity sites.
Amber-tinted darkness — ideal for reading at night. Reduces blue light for better sleep quality.
Sapphire-tinted dark mode — sleek and futuristic. Perfect for developers and tech lovers.
Pure black (#000) backgrounds — saves battery on OLED screens and delivers the deepest dark mode.

Yes — Dark Mode Master uses DarkReader's industry-leading engine with document_start injection, so dark mode is applied before the page renders. It works on virtually every website including JavaScript-heavy SPAs like ChatGPT, GitHub, and Twitter.
Dark Mode Master detects sites with native dark mode support via prefers-color-scheme. On those sites, it respects the native implementation rather than double-applying dark mode. You can also manually exclude any site.
Absolutely not. All settings — themes, schedules, site rules, plan status — are stored locally in Chrome's storage. No backend, no analytics, no user accounts, no data ever leaves your device. Geolocation for sunrise/sunset is calculated entirely offline.
Dark Mode Master uses a pure math formula (USNO algorithm) to calculate local sunrise and sunset based on your latitude/longitude. Your location is captured once by the browser's Geolocation API, stored locally, and all subsequent calculations happen on-device with no network requests.
Lifetime unlocks the full Pro feature set: all premium themes, appearance sliders, font color controls, smart scheduling, and per-site custom appearance. You pay once ($10) and keep all future updates forever.
Yes! Dark Mode Master is built natively on Chrome Extension Manifest V3 — the current and future-proof standard. It uses service workers instead of background pages and fully respects all MV3 security constraints.
