VideoCore YouTube Downloader — Privacy Policy

Last updated: 26 August 2026

In short: this extension collects nothing. It reads what your own browser has already displayed on the YouTube page you are looking at — transcripts, comments, thumbnails — and hands it to you as a file. There is no account, nothing is uploaded, and nothing about you is stored on our servers, because it never contacts them.

Who this covers

This policy applies to the VideoCore YouTube Downloader browser extension (transcripts, comments and thumbnails, including bulk transcript collection) published by VideoCore (videocore.uk). It does not cover VideoCore Lens, which is a different extension that signs you in and communicates with our servers — see the VideoCore Lens privacy policy for that one.

What the extension accesses

The YouTube page you are viewing (www.youtube.com host permission): it reads the transcript panel, the comment section, and thumbnail image URLs that YouTube itself has rendered or published for that page. In bulk mode it navigates your tab through the videos of a playlist, your Watch Later, or a channel page — visibly, under your control, and cancellable at any time — and reads each page the same way.
downloads permission: used solely to save thumbnail images (which are cross-origin files on i.ytimg.com) through the browser's download manager when you click a save button. Nothing is downloaded without your click.
storage permission: used solely to remember your settings (which tools are switched on, format preferences), the progress of a bulk run, and whether you have dismissed the one-time review prompt. This data stays in your browser.

What the extension does NOT do

It makes no network requests of its own — the YouTube page does its own, normal, authorised loading; the extension only reads what is rendered.
It has no account, no sign-in, no analytics, no telemetry.
It does not read your browsing history, your other tabs, or any site other than the YouTube page it runs on.
It does not transmit, sell or share any data with anyone, including us.

Links to VideoCore

Panels include ordinary links to free tools on videocore.uk (for example Script Lab). These are plain links: nothing is sent unless you click one, and clicking one simply opens the page in a new tab with a standard utm tag identifying that the visit came from the extension. No identifier of you is attached.

Data retention

All settings and bulk-run progress live in your browser's local extension storage and can be removed at any time by uninstalling the extension. We hold nothing to delete on our side.

Changes

If a future version changes any of the above, this page will be updated first and the change described plainly in the extension's changelog.
