Privacy Policy
BoostMate — Volume Booster & Speed Controller
Last updated: October 31, 2026 · Version 1.0.1
Local media processing
BoostMate processes media locally in your browser. It does not send audio, personal data, or browsing history to a server. It has no analytics, advertising, remote scripts, or remote fonts. It finds HTML audio/video elements on supported webpages to control volume, playback speed, and dialogue emphasis. It does not record or upload media or collect webpage text.
Preferences stored on your device
BoostMate stores volume, playback speed, Clear Audio, enabled/disabled state, and scope preferences using Chrome extension storage. Website preferences include the website hostname. Temporary tab identifiers and their preferences are stored for the current browser session.
Website and global preferences remain locally until changed or the extension is removed. Tab preferences are removed when a tab closes or the browser session ends. BoostMate does not keep chronological browsing history, full page URLs, visit timestamps, or page titles.
Website access
Website access lets the packaged content script find media on supported webpages and embedded frames. The popup reads the current website hostname to save and restore website preferences. This access supports media controls, not tracking.
Sharing and third parties
The extension does not sell, share, or transfer user data to third parties. Media supplied by websites remains subject to those websites' own privacy practices.
Your choices
Change preferences or disable processing in the popup. Manage website access in your browser's extension settings. Removing BoostMate removes its extension storage from that browser profile. Choosing website scope replaces tab overrides for that website; choosing all-tabs scope replaces existing website and tab overrides.
