Commentary Off Privacy Policy

Last updated: October 3, 2026 (applies to Commentary Off version 1.0.0)

Commentary Off is a Chrome extension that turns down the TV commentary in the sound of a browser tab. It does all of its work on your computer. It has no servers, makes no network requests, and contains no analytics, advertising or tracking. The developer receives no information about you or how you use it.

Audio from the tab

When you click the Commentary Off icon and switch it ON, Chrome gives the extension the sound of that tab. The extension processes this sound in memory on your computer, using a speech-separation model that is included in the extension, and plays the result back to you. The audio is not recorded, not saved and not sent anywhere. Processing stops when you switch it OFF, close the tab, or Chrome ends the capture. The extension does not use your microphone or camera.

Other information the extension reads

• The address of the current tab. When you open the popup, the extension checks the tab's web address to see whether Chrome allows its sound to be used (Chrome's own pages, for example, can't be). While processing is on, it keeps the site name (for example "example.com") to show which tab is in use.
• YouTube pages. On www.youtube.com and m.youtube.com, a small script included in the extension reads the page address, the video ID, the page title, and whether the video is playing, muted or live. It does this whenever a YouTube page is open, so the popup can tell whether a video is present. It does not read comments, your account, or anything else on the page.

This information stays inside the extension on your computer. It is kept in Chrome's temporary extension storage, which is held in memory and cleared when you quit Chrome. The details for a tab are also removed when you close that tab. None of it is sent anywhere.

What is stored

In normal use, Commentary Off saves nothing permanently. If you open the hidden developer diagnostics panel, the popup remembers a single on/off setting for that panel on your computer. Uninstalling the extension removes everything it stored.

Sharing

Commentary Off does not sell, share or transfer any information to anyone, because no information leaves your computer.

Links

• Tip the developer opens the developer's page on Ko-fi (https://ko-fi.com/commentaryoff) in a new tab, only when you click it. The extension adds no information to that link. Ko-fi is a separate service, and its own privacy policy applies to your visit and to any tip you choose to send.
• Share with friends copies the extension's Chrome Web Store link to your clipboard when you click it. The extension never reads your clipboard.

Permissions

• tabCapture: to get the sound of the tab you switch ON.
• offscreen: to process that sound in a hidden extension page, because Chrome extensions can't process audio in their background script.
• activeTab: to work with the tab you are on when you click the icon.
• storage: to keep the temporary on/off state described above.
• scripting and access to www.youtube.com and m.youtube.com: to run the small YouTube script described above.

Changes

If this policy changes, the new version will be posted at this address with a new "Last updated" date.
