Privacy Policy

Last updated: March 12, 2026

Overview

DiffSpot is a Chrome extension that monitors web pages for changes. Your privacy is important to us. This policy explains what data DiffSpot collects and how it is used.

Data Collection

DiffSpot collects and stores the following data locally in your browser (using Chrome's storage API):

• URLs you choose to monitor
• CSS selectors you configure
• Page content snapshots (for comparison purposes)
• Change history records (diff results)
• Your extension settings and preferences

Data Storage

All data is stored locally in your browser using chrome.storage.local. No data is transmitted to any external server.

Data Sharing

DiffSpot does not:

• Send your data to any external server
• Share your data with third parties
• Use your data for advertising
• Track your browsing activity
• Collect personally identifiable information

Network Requests

DiffSpot makes HTTP requests only to URLs that you explicitly configure for monitoring. These requests are made directly from your browser to the target website. No proxy or intermediary server is involved.

Permissions

DiffSpot requires certain browser permissions to function:

• storage — Save your settings and monitoring data locally
• alarms — Schedule periodic page checks
• notifications — Alert you when changes are detected
• offscreen — Fetch pages without opening visible tabs
• activeTab — Access the current tab for element selection
• contextMenus — Provide right-click "Monitor this page" option
