Privacy policy
Speed Lab privacy
This policy explains what Speed Lab handles, why it handles it, and where the information stays.
Overview
Speed Lab is a Chrome extension that provides precise playback-speed controls for YouTube videos.
Speed Lab processes playback information locally so it can show controls, apply a selected speed, and remember user preferences.
Information handled locally
Speed Lab stores these settings in Chrome:
- Default playback speeds
- User-created speed presets
- Keyboard shortcut preferences
- Playback-speed memory preferences
- Player-control visibility preferences
- Current-tab playback-speed memory
Speed Lab also processes the current YouTube page type, the active HTML video element, and requested playback-rate changes. This processing occurs locally in the browser.
How information is used
Speed Lab uses this information only to:
- Display playback-speed controls
- Apply the playback rate selected by the user
- Remember user-selected settings
- Restore playback preferences during YouTube navigation
- Provide separate behavior for standard videos and Shorts
Data not collected
Speed Lab does not collect or transmit:
- Names, email addresses, or identification numbers
- Google or YouTube account information
- Passwords or authentication information
- Video titles or channel names
- YouTube watch history or general browsing history
- Personal communications
- Financial, health, or location information
- Analytics, advertising, or tracking identifiers
- Keystroke logs or records of shortcut use
Data transmission
Speed Lab does not use external servers, analytics providers, advertising systems, or telemetry services.
Storage and retention
Persistent preferences are stored with
chrome.storage.local. They remain until the user
resets Speed Lab or removes the extension.
Current-tab speed memory is stored with
chrome.storage.session. Session information expires
with the relevant browser session.
Permissions
- Storage: saves playback settings and current-tab speed memory.
- Scripting: reconnects packaged extension code to YouTube tabs that were already open or need to reconnect after an update.
-
YouTube host access: locates the active
video, displays the speed control, and applies the selected
playback rate on
youtube.comandm.youtube.com.
Remote code
Speed Lab does not download or execute remote JavaScript or WebAssembly. All executable extension code is included in the extension package distributed through the Chrome Web Store.
User controls and deletion
Users can delete stored Speed Lab information by:
- Opening Speed Lab settings and selecting Reset settings
- Removing Speed Lab from Chrome
Chrome Web Store Limited Use
Speed Lab uses information only to provide or improve the product's disclosed playback-speed functionality. Its information handling complies with the Chrome Web Store User Data Policy, including Limited Use requirements.
