Privacy Policy

Effective date: September 12, 2026

1. Information handled

• Video and page context: The extension detects HTML5 video elements, their visibility, playback state, and frame location so it can select and control the relevant video. This information is processed locally and is not uploaded.
• Per-tab settings: The enabled state, playback speed, volume, and custom limits are stored locally in Chrome session storage. Settings are kept separate for each tab and are not used to build website profiles or browsing history.
• Saved presets: Speed and volume values saved by the user are stored locally in Chrome storage. Up to three presets can be saved, and presets are independent of websites.
• Tab audio: When the user selects a volume above 100%, the extension temporarily captures audio from the current tab and processes it locally with the Web Audio API. The default volume range is 0–200%; users can set custom limits up to 1000%. The audio is not recorded, stored, or sent to external servers.

2. How the information is used

The information described above is used only to control video playback speed and volume, apply sliders, numeric values, and presets, detect videos in iframes and open Shadow DOM trees, restore controls after navigation or a service worker restart, and provide optional local tab-audio boosting.

3. External transmission and sharing

Universal Video Controller does not send audio, page content, browsing history, URLs, settings, or preset values to developer-controlled servers, advertising networks, analytics services, or other third parties. We do not sell or share user data, and there is no feature that allows a person to view user data.

4. Storage and deletion

Per-tab settings are stored in Chrome session storage and are removed when Chrome or the extension discards the session data. Saved presets remain in Chrome's local extension storage until the user deletes them or removes the extension. The extension does not store page content, browsing history, or audio recordings.

5. Permissions

• <all_urls>: Required to detect and control HTML5 videos on supported websites, including videos in iframes and open Shadow DOM trees.
• storage: Required to save per-tab settings and user-created presets locally.
• tabCapture: Required to capture the current tab's audio when the user selects volume above 100%.
• offscreen: Required to process captured tab audio locally with the Web Audio API.
• webNavigation: Required to enumerate frames and restore video control after navigation or a service worker restart.

6. Remote code

The extension does not load or execute remote JavaScript. All extension logic is included in the published extension package.

7. User controls

You can turn the controller on or off from the extension popup, delete saved presets individually, and remove the extension at any time from Chrome's extension management page.

8. Support

For support, please use the support channel provided in the Chrome Web Store listing.

9. Policy changes

If the extension's data handling practices change, this page will be updated and the effective date will be revised.
