Privacy Policy

Last updated 4 November 2026

None of these extensions collect, sell or share your data. They have no accounts, no analytics and no ads, and they don't send anything to me or to anyone else. What each one does with the data it touches is described below.

Playlist Multi-Save

• It runs only on youtube.com. When you open its grid, it reads your playlists from YouTube, and when you click Save, it asks YouTube to add or remove the video. It does this the way YouTube's own Save button does: inside the YouTube page, signed in with your existing YouTube session.
• Your playlists and your sign-in stay between your browser and YouTube. The extension never sends them anywhere else.
• Your grid settings (sort order, columns, card size, thumbnails, closing behaviour) are stored with Chrome's sync storage, so Chrome syncs them between your own browsers if you have Chrome sync turned on.
• To show playlist covers quickly, it keeps their image links in youtube.com's storage in your browser.

YouTube MP3 Cutter

• It runs on YouTube. When you click Download, it passes the video's address and the start and end times you picked to the helper app installed on your own computer. The helper downloads only that part of the video from YouTube and saves it to your Downloads folder.
• Your settings and the times you've marked for each video are stored in Chrome's storage in your browser.
• Nothing is sent anywhere except to YouTube, to fetch the video.

AI Chat Bulk Delete

• It runs on Google AI Mode, Gemini, Claude and ChatGPT. It reads the chat titles in the site's sidebar so you can select them, and it deletes the chats you pick by clicking the site's own delete buttons for you.
• It stores a count of how many chats you've deleted, shown in its popup, in Chrome's storage in your browser, and the position of its toolbar in the site's storage in your browser.
• The debug button copies a description of the page to your clipboard, with chat titles and links masked, but only when you click it. Nothing leaves your computer unless you paste it somewhere yourself.
• Nothing is sent anywhere.

Changes

If an extension's handling of data changes, this page will be updated before the new version is released.
