ValDam DarkHelper: Total Customization for a More Comfortable and Accessible Browsing Experience ValDam DarkHelper is a 100% local and private Chrome extension designed to transform your browsing experience. Its primary goal is to customize the appearance of the web pages you visit by applying dark themes and advanced readability and accessibility options. It requires no internet connection, collects no data, and includes no telemetry—everything works within your browser, with no external dependencies. Key Features 6 Predefined Themes: Dark, Light, Eco OLED (pure black #000), High Contrast, Sepia Reading, and Dracula. Perfect for adapting to different lighting conditions or visual preferences. Smart Native Theme Detection: If a website already has its own dark mode (via prefers-color-scheme, data-theme, or toggles), the extension detects it and allows you to activate the site’s native theme instead of forcing external CSS. Anti-White Background Compatibility: Automatically fixes form controls, tables, and light surfaces that resist dark themes using CSS and a MutationObserver for dynamic content (including iframes). Advanced Side Panel Editor: Customize colors, fonts, size, line spacing, and text spacing for any webpage. Real-time adjustments with instant preview. Accessibility for All: High contrast mode to improve visibility. Dyslexia mode for easier reading. Color blindness filters (protanopia, deuteranopia, etc.). Domain-Specific Rules: Set specific themes or adjustments for individual websites. Automatic Time-Based Mode: Switch between light and dark themes automatically based on the time of day you configure. Privacy and Security 100% local: All settings are saved in chrome.storage.local, within your browser. No external connections: It does not make network requests or collect data. No dependencies: Pure JavaScript, ready to load directly into Chrome. Why Install It?
