Pacer – Lecture Video Speed Controller runs entirely inside your browser.
- It has no server. It does not create accounts and does not ask for an email address.
- It collects no analytics, telemetry, crash reports or usage statistics.
- Everything it stores (settings and the content you create with it) is kept in your browser's local extension storage on your device. You can export it as a file and delete it at any time from the extension's settings page.
- It does not sell, share or transmit your data to anyone, because it never leaves your computer.
Permissions
The extension asks Chrome for the following, and uses each only as described:
- storage — Saves your settings, per-site speeds and resume positions locally.
- scripting — Registers a tiny document-start script so video players that hide their <video> element in a closed shadow root can still be controlled. It patches only attachShadow and does nothing else.
- Access to all sites — The speed pill must appear on any video without a click, and universities use many different video platforms on unpredictable domains. Pacer only reads <video> elements; it never reads page content.
Data retention
Data exists only in your browser's local extension storage for as long as the extension is installed. Removing the extension deletes its local data. No copy exists anywhere else.
Changes
If a future version ever changes what the extension stores or where, this page and the extension's store listing will say so before that version ships.
