1. Introduction

ZenFocus ("we," "our," or "the extension") is committed to protecting your privacy. This Privacy Policy explains how we handle information when you use our Chrome browser extension.

2. Information We Do NOT Collect

ZenFocus is designed with privacy as a core principle. We do not collect, transmit, or store any of the following:

• Personal Information: No names, email addresses, or contact information
• Browsing History: We do not track or record which websites you visit
• User Activity: We do not monitor your browsing behavior or habits
• Analytics Data: We do not use any analytics or tracking services
• Cookies: We do not set or use any cookies
• Device Information: We do not collect device identifiers or system information

3. Data Storage

ZenFocus stores the following data locally on your device only using Chrome's local storage API:

• Blocked Sites List: The list of websites you choose to block
• Focus Mode State: Whether focus mode is currently enabled or disabled

This data:

• Never leaves your browser
• Is not transmitted to any server
• Is not accessible to us or any third party
• Can be deleted at any time by removing the extension

4. Permissions Explanation

ZenFocus requires certain Chrome permissions to function. Here's why we need each one:

4.1 Storage Permission

Used to save your blocked sites list and focus mode preferences locally on your device. This ensures your settings persist even after closing the browser.

4.2 Tabs Permission

Required to monitor when you navigate to a blocked website so we can display the focus screen. We do not track or record your browsing history.

4.3 ActiveTab Permission

Allows the extension popup to function when you click the extension icon. This is necessary for the user interface to work properly.

4.4 Host Permissions (all_urls)

Enables the extension to block websites across all domains. This permission is necessary because users can block any website they choose. We do not access or collect data from any websites.

5. Third-Party Services

ZenFocus does not use any third-party services, including:

• No analytics services (e.g., Google Analytics)
• No advertising networks
• No external APIs or servers
• No remote code or scripts

6. Data Sharing

We do not share any data because we do not collect any data.

Your information stays on your device and is never transmitted to us, third parties, or any external servers.

7. Children's Privacy

ZenFocus does not knowingly collect any information from anyone, including children under the age of 13. Since we do not collect any data at all, the extension is safe for users of all ages.

8. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated "Last Updated" date. We encourage you to review this Privacy Policy periodically.

9. Open Source

ZenFocus is open source. You can review our code to verify our privacy practices at any time.

10. Your Rights

Since we do not collect any personal data, there is no data for us to access, modify, or delete. You have complete control over your data:

• View your data: All settings are stored locally in Chrome's storage
• Delete your data: Simply uninstall the extension
• Export your data: Your blocked sites list is stored in Chrome's local storage
