Summary
Scroll Volume does not collect, sell, transmit, or analyze personal data for the extension developer. It has no developer-operated remote service and does not require an account.
Settings and site rules
The extension saves its settings and exact per-site hostname rules in the browser’s storage.sync service. These values can include volume-step preferences, activation and HUD preferences, YouTube behavior, and whether Scroll Volume is enabled for an exact hostname.
If browser sync is enabled, the browser vendor may transmit, retain, and synchronize those values across your signed-in browser profiles under its own privacy policy. The extension developer does not receive them.
Page and video access
Scroll Volume runs a content script on webpages and embedded frames so it can identify a video under the pointer and adjust its volume. On supported YouTube pages, it locally reads and updates the selected YouTube player’s volume state.
That processing happens in the browser. Page text, video history, settings, site hostnames, and browsing activity are not sent to the extension developer or a developer-operated service.
Permissions
- Storage: saves extension settings and exact per-site hostname rules.
- Broad page matching: allows the extension to work on HTML5 video players that can appear on any website or in an embedded frame.
Third-party services
Chrome Web Store, Microsoft Edge Add-ons, Chrome, and Edge may independently process store visits, installs, diagnostics, sync data, and usage information under their own terms. Those vendor services are separate from Scroll Volume and are not controlled by the extension developer.
Retention and deletion
Scroll Volume does not maintain a developer database. You can remove a site rule in the extension settings, reset all settings, or uninstall the extension. Browser-vendor sync and backup retention remain subject to the vendor’s policies.
