NightGuard - Web Eye Care

NightGuard is not just another dark mode extension—it’s a comprehensive digital wellbeing and eye care platform built specifically for Safari. Instead of simply inverting colors, NightGuard introduces a quantified approach to your night-time browsing, ensuring every webpage you visit is comfortable, battery-efficient, and trackable. Set it up once, and let it automatically protect your eyes every day. Key Features: Quantified Eye Care Dashboard (Exclusive) Stop guessing about your eye strain! Our built-in dashboard tracks your dark mode reading duration and calculates a "Dark Shield Index." See your most visited sites and visualize your digital wellbeing at a glance. Smart Sunset & Sunrise Sync Powered by a local astronomical algorithm (no network or exact location needed), NightGuard calculates your local sunset time and automatically enables dark mode exactly when dusk falls. Battery-Aware Engine Running low on battery? NightGuard can automatically switch to a pure-black OLED theme when your battery drops below your chosen threshold, extending your device's battery life while protecting your vision. 20+ Ergonomic Themes We go beyond pure black. Choose from meticulously crafted themes like "Reading Focus," "Soothing Nature," or "High Contrast Accessibility." Each theme comes with an Eye Care Rating to suit different reading environments. Privacy First All color calculations and screen time analytics are processed strictly locally on your device. We NEVER collect your browsing history, and there are absolutely no ads or third-party trackers. Bonus Features: • One-click to hide annoying cookie consent banners (opt-in). • Fine-tune theme and toggle settings for specific websites.
