Rei Sidebar Privacy Policy

Last updated: November 20, 2025

Overview

Rei Sidebar is a Chrome extension that provides an Arc-style sidebar for managing tabs, tab groups, pinned tabs, and related settings. We designed the extension to work entirely on your device without sending browsing data to external servers.

Data We Collect

• No personal data is collected or transmitted by the extension.
• Tab titles, URLs, favicons, group metadata, pin states, collapse states, and theme preference are stored locally inside the browser.

Storage and Retention

All extension state is saved in chrome.storage.local on your device. Data stays there until you remove the extension, clear the extension data, or explicitly clear ghost tabs within the UI.

Permissions Rationale

• tabs & activeTab: Read current tabs to display them and activate or close tabs you select.
• tabGroups: Read and toggle Chrome tab groups so the sidebar stays in sync.
• sidePanel: Render the UI in Chrome's side panel.
• storage: Persist your sidebar state (groups, pin states, theme) locally.

Third-Party Sharing

The extension does not send data to or share data with any third parties.

Children's Privacy

The extension is intended for general audiences and does not target children. We do not knowingly collect information from children.

Changes to This Policy

If this policy changes, we will update the “Last updated” date and include the revised copy in the published package.
