At TabMaster, we respect your privacy and are committed to protecting it. This Privacy Policy explains what information we collect, how we use it, and what rights you have in relation to it.
We've designed TabMaster with privacy-first principles. Our core philosophy is to collect as little data as possible while providing you with a powerful tab management experience.
We do not collect, transmit, or share any of your personal data. The TabMaster extension operates entirely on your device and does not send any data to external servers.
The only information the extension processes is:
Information about your open tabs (URLs, titles, and favicon URLs)
Your extension preferences and settings
All of this information is stored locally on your device and is never transmitted to us or any third parties.
Since we don't collect any information, we don't use your information for any purpose beyond the functionality provided by the extension itself on your local device.
The tab information processed by the extension is used solely to:
Display your saved tabs within the extension interface
Allow you to organize and manage your tabs
Restore your tabs when requested
All data is stored locally on your device using the browser's built-in storage API (chrome.storage). This includes:
Your saved tab groups
Extension preferences (sorting options, etc.)
This data remains on your device and is not accessible to us or any third parties. It is only accessible to the TabMaster when you use it.
TabMaster requires certain browser permissions to function properly. Here's why each permission is needed:
tabs: Required to access and manage your browser tabs (view, create, modify, and organize tabs)
storage: Required to save your tab groups and preferences locally on your device
windows: Required to manage browser windows when capturing and restoring tabs
We request only the minimum permissions necessary for the extension to function as intended.
Since all data is stored locally on your device, you have complete control over data retention. You can clear all stored data at any time by:
Using the "Clear All Data" button in the extension's options page
Uninstalling the extension
We may update our Privacy Policy from time to time.
You are advised to review this Privacy Policy periodically for any changes. Changes to this Privacy Policy are effective when they are posted on this page.
