Privacy Policy
Last updated: June 3, 2026. Your privacy is paramount. Discover how we ensure your recordings remain 100% yours.
1. Local-First Architecture
cx-tab-recorder-plus is designed from the ground up as a local-first application. This means:
- No Transmission: We do not collect, transmit, or share your screen/audio recordings, keys, settings, or logs with any external cloud databases or third-party tracking services.
- No Server Processing: Video encoding and muxing are processed inside Google Chrome's local JS sandbox context.
- Full Offline Capability: The extension functions completely offline without internet connectivity.
2. Permissions & Justification
To enable screen capture functionality, the extension requests the following API permissions from Chrome:
| Permission | Why it is required |
|---|---|
| tabCapture | Allows the extension to request the media stream (video/audio) of the active browser tab. |
| offscreen | Allows creating a background document to ensure stable recording and file compression when navigating other tabs. |
| downloads | Used solely to trigger download sequences to transfer the output WebM video file from the browser sandbox to your computer's local download path. |
| audio | Used optional overlay recording of external microphones when toggled by the user. |
3. Policy Updates
We may update our Privacy Policy to reflect changes in web platform capabilities or security guidelines. If changes are made, we will update the date at the top of this document. We encourage users to check this page periodically for updates.
