LumaTune

LumaTune helps you adjust how videos look and play directly in your browser. Use the Tune tab to quickly control brightness, contrast, saturation, and playback speed up to 8x. Each control includes a precise numeric input, real-time updates, and an individual reset button. Control settings are isolated by website origin, so changing one site does not alter unrelated sites. The compact on-video panel follows the most relevant video and provides the current speed, speed steps, quick choices, temporary disable, and reset without repeatedly opening the extension popup. It works with dynamic media and compatible embedded players after optional access is enabled. Theater Mode maximizes the relevant player inside the browser window while keeping tabs and browser controls visible. Press Esc at any time to exit immediately. It stays active across tab focus, Windows virtual-desktop changes, and extension service-worker restarts. Contain mode shows the whole video, and Pro adds Cover, zoom, positioning, background color, and optional per-site preferences. LumaTune Pro unlocks advanced visual tools, including gamma, sharpness, RGB color balance, custom presets, and the ability to apply adjustments to videos, images, or the whole page.

Privacy-first design: - No browsing history collection - No website cookie collection - No password or form data collection - No page-content collection or transmission - Settings and presets are stored in Chrome extension storage - A site origin is stored locally only when the user explicitly hides the video panel or saves Theater preferences for that site - ExtensionPay may use Chrome Sync storage to cache the API key and license status - Automatic restoration and embedded-player controls across websites require one explicit optional website-access grant; this access is not granted during installation and can be revoked in Chrome settings - Trial and payments are handled by ExtensionPay
