Domain Blocker for Google Search is committed to user privacy. The extension:
- Does not collect any personal information
- Does not track user behavior or search history
- Stores all blocklist data locally on the user's device
- Does not communicate with external servers
- Does not use analytics or tracking tools
- Does not share any data with third parties

The only data stored is your personal blocklist of domains, which remains entirely under your control and stored locally in your browser.
