BrowSync Extension Privacy Policy

This Privacy Policy explains how the BrowSync browser extension (for Chrome, Arc, Edge, and Brave) handles data when used together with the BrowSync desktop app.

1. Single Purpose

The extension has one purpose: enable local cross-browser synchronization and browser routing through a connection to the BrowSync desktop app on your device.

2. What Data Is Processed

The extension may process the following browser data to provide synchronization features:

Bookmarks
Tab state and URLs
Cookies
localStorage and sessionStorage
Extension runtime state and sync metadata stored in extension storage

3. How Data Is Used

Synchronize selected browser data across supported browsers on the same device.
Maintain connection state and sync task scheduling.
Apply user-configured browser routing behavior.

4. Data Transfer and Sharing

BrowSync extension communicates with the local BrowSync daemon at ws://127.0.0.1:62333. Data is processed locally on your device.

The extension does not send your browsing data to BrowSync cloud servers, third-party analytics services, advertising networks, or data brokers.

5. Permissions and Why They Are Needed

bookmarks: read and write bookmarks for local synchronization.
tabs: read tab metadata required for tab-state sync and routing workflows.
cookies: synchronize site session cookies across supported browsers locally.
storage: store extension configuration, state, and sync metadata.
scripting: support sync behavior where script-based page interaction is required.
alarms: schedule heartbeat, reconnect, and background sync maintenance tasks.
unlimitedStorage: preserve larger local sync state when needed.
host permissions (<all_urls>): access site storage data required for synchronization features.

6. Data Retention and Deletion

Extension data is stored locally on your device. You can delete this data by removing the extension and, if desired, clearing BrowSync app data from your system.

7. Security

BrowSync is designed to minimize external data exposure by keeping sync traffic local. As with any local software, device security and browser security settings remain your responsibility.

8. Children's Privacy

BrowSync is not directed to children under 13, and we do not knowingly collect personal data from children.

9. Changes to This Policy

We may update this Privacy Policy from time to time. Updated versions will be posted at the same policy URL with a revised "Last updated" date.
