Privacy Policy for YouTube Picture-in-Picture & Live Activities
Last updated: September 9, 2026
This policy covers the Chrome extension published as YouTube Picture-in-Picture & Live Activities ("the Extension").
Summary
The Extension does not collect, transmit, sell or share any data. There are no servers, no accounts, no analytics and no telemetry. It makes no network requests of its own. Everything it knows lives in your own browser, on your own computer.
What the extension accesses
The one page you point it at. When you press "Track this page", the Extension reads the visible value from that page - a score, a price, or the video's playback state - and watches it for changes. That reading happens entirely inside your browser, on a page you already had open. Nothing about it is recorded or transmitted.
Your other tabs, to draw on them. To show the pill wherever you go, the Extension runs a small content script on the pages you visit. That script is used only to draw the pill and to receive score updates. It does not read, record or transmit the content of those pages.
The address of the active tab, momentarily. To decide whether the toolbar icon should show its green "I can mirror this" dot, the Extension checks whether the current tab's address matches one of the sites it supports. This check happens on your device as you switch tabs. Addresses are not stored or transmitted, and no browsing history is collected.
The YouTube video element, when you ask it to. On a YouTube tab, the Extension controls the page's own video element - play, pause, seek, mute - and hands it to Chrome's native picture-in-picture window. It does not access your YouTube account, your watch history, your subscriptions or any cookies.
What is stored on your device
Everything below lives in your browser's own extension storage, on your computer, and is never uploaded:
| Stored | Where | Why |
|---|---|---|
| Which tab you chose as the source, and the most recent value read from it | Session storage (lspState) | So the pill can still show the value after Chrome suspends the extension's background worker. Cleared when you close the browser. |
| Where you dragged the pill | Local storage (pillPosition) | So it stays where you put it, on every tab |
| Your settings - whether to track automatically, whether the pill shows on every tab, whether you have seen the tour | Local storage (lspSettings) | So your preferences survive a browser restart |
| A count of how many times you have started tracking, the date you installed it, and whether you have dismissed the review prompt | Local storage (lspSettings) | So the "enjoying this?" prompt appears once, after the extension has actually been useful, and never again once you dismiss it |
None of these values is sent anywhere. Uninstalling the Extension removes all of them.
What the extension does not do
- No data of any kind is sent to the developer or to any third party.
- No analytics, telemetry, tracking pixels, advertising or fingerprinting.
- No accounts, registration, sign-in or email collection.
- No browsing history collection or profiling.
- No selling or sharing of data, because none is collected.
- No remote code: every line of JavaScript ships inside the extension package, and nothing is downloaded or executed from the internet at runtime.
Why it asks for what it asks
Chrome's install dialog lists permissions in broad terms, which can read alarmingly. Here is what each one is actually for:
| Permission | Used for |
|---|---|
activeTab, scripting | Injecting the reader into the one tab you chose, when you choose it |
tabs | Knowing which tab is the source, noticing when it is closed or reloaded, and sending the value to the others |
storage | The settings and pill position listed above |
| Access to the supported sites | Reading the score, price or video state from YouTube, YouTube Music, Cricinfo, ESPN, BBC Sport, Yahoo Finance, CoinGecko, TradingView and Polymarket |
| Access to all sites | Drawing the pill on whatever tab you are looking at. This is the only thing it is used for - the content script does not read page content on any site other than the source you picked. |
Third parties
There are none. The Extension has no analytics provider, no error reporting service, no advertising network and no backend. The only servers involved are the ones belonging to the websites you were already visiting.
Children
The Extension is not directed at children and collects no data from anyone, of any age.
Changes to this policy
If the Extension ever changes in a way that affects this policy, this page is updated and the date at the top changes with it. Since the Extension collects nothing, any such change would be announced before it shipped, not after.
