Block AutoPlay: privacy policy
Effective November 4, 2026
Block AutoPlay is a personal Chrome extension, published privately in the Chrome Web Store for its developer's own use. It isn't offered to the public. This policy describes exactly what it does with data.
In short: Block AutoPlay sends nothing anywhere. It makes no network requests, has no servers, and uses no analytics. It stores only the list of websites it is switched on for, with two switches for each one, in the browser.
What is stored
| What | Where | Why | How long |
|---|---|---|---|
The websites the extension is switched on for (for example example.com), and for each whether autoplay blocking and auto-refresh blocking are on. |
chrome.storage.sync. If Chrome sync is on, Chrome also copies this list to the user's own Google account so it is available on their other computers. |
So the extension knows where to act. | Until the site is removed or the extension is uninstalled. |
| A count of what was stopped on the page open in each tab (numbers of videos, audio and refreshes). | chrome.storage.session, in memory only. |
To show "Stopped on this page" in the popup. | Until the tab moves to another page or closes, or Chrome restarts. |
Nothing else is stored. There are no accounts, no identifiers and no browsing records.
What the extension reads
The address of the current tab, when its popup is opened, to show which site its switches apply to. The address isn't stored unless blocking is switched on for that site.
On the websites it is switched on for, and only there:
- It watches when video and audio on the page try to start, and pauses them unless the user pressed play.
- It notes which part of the page was just clicked, or whether a play key (Space, Enter or K) was pressed, so it can tell the user's own play from the site's autoplay. This is kept in the page's memory for a few seconds, then replaced, and never stored or sent.
- It cancels reloads the page starts by itself while the page is being read.
It never reads page text, forms, passwords, cookies or browsing history. On any other website it does nothing.
What is shared
Nothing. Block AutoPlay doesn't sell, transfer or share any data, and doesn't use it for advertising, credit decisions or anything unrelated to its single purpose: stopping autoplay and auto-refresh on the websites it is switched on for.
Deleting the data
Remove a site in the extension's popup or on its "Manage all sites" page, or uninstall the extension to delete everything it stored. Per-tab counts disappear by themselves.
These web pages
This site is a set of static pages. It sets no cookies and runs no analytics. Like any website, the hosting provider (Cloudflare) may process standard request data, such as IP addresses, to deliver the pages.
Changes and contact
Changes to this policy will be published on this page with a new effective date. For questions, use the support option on the extension's Chrome Web Store page.
