Short version: A-B Loop runs 100% on your own device. It collects nothing, sends nothing, makes no network requests, has no servers and no account. The loop points you set never leave your browser.
A-B Loop lets you set an A point and a B point on a video on the page
you are viewing, and then repeats that segment. It only adjusts the playback position of the
<video> element you are already watching — exactly as if you dragged the progress bar back
yourself. That is all it does. It does not download, record, or copy the video.
None. A-B Loop has no servers, no account, no sign-in, no sync, and no backend. We do not collect, transmit, store, sell, or share any of your data — not the loop points you set, and no personal or usage data. We cannot see any of it.
The named loops you save (a short text label plus two timestamps, grouped by website) are stored
locally on your device using the browser's storage API. They stay on your
machine and are never uploaded anywhere.
No. A-B Loop makes no network requests of any kind — no servers, no analytics, no CDNs, no API calls. It works fully offline.
A-B Loop requests only three permissions, each used narrowly:
activeTab and scripting — used only when you open the popup and act
on the current page, to run a small script that finds the video element and adjusts its playback
position for the loop. This happens on your device. No host permissions are requested, so it does not run
on pages in the background.storage — used only to remember your saved loops and your last segment,
stored locally on your device.Uninstalling the extension removes the saved loops it has stored. A-B Loop keeps no data anywhere else, because there is nowhere else — it has no servers.
None. No analytics, no ads, no trackers, no external SDKs, no remote code.
