1. Information We Collect

1.1 Local Data Only

ScreenLimit stores the following information locally on your device using Chrome's storage API:

• Time tracking data: Minutes spent on entertainment websites

• User preferences: Your daily limit settings and notification preferences

• Browsing history or URLs visited
• Content of web pages you view
• Passwords or login credentials
• Search queries or form data

2. How We Use Your Information

2.1 Local Processing Only

All data processing happens locally on your device. Your information is used solely to:

• Provide gentle reminders about your screen time goals
• Display daily usage statistics in the extension popup
• Save your preferences and settings

2.2 Site Categorization

ScreenLimit automatically categorizes websites into three types:

• Entertainment sites: Where time tracking is active (e.g., YouTube, Netflix, social media)
• Work sites: Where time tracking is paused (e.g., Gmail, Google Docs, GitHub)
• Neutral sites: Where no tracking occurs

This categorization happens locally and does not involve sending website information to external servers.

3. Data Storage and Security

3.1 Local Storage

All data is stored locally using Chrome's built-in storage system:

• Data never leaves your device

• You can clear all data by uninstalling the extension

3.2 Data Retention

ScreenLimit retains data locally for functionality purposes:

• Daily usage data is kept to show weekly and monthly trends
• Old data may be automatically cleaned up to prevent excessive storage use
• You can manually reset all data through the extension settings

4. Third-Party Services

5. Permissions Explanation

5.1 Why We Need Permissions

ScreenLimit requests minimal permissions necessary for core functionality:

Host Permissions (<all_urls>):

• Required to detect which website you're currently viewing
• Enables automatic categorization of entertainment vs. work sites
• Allows the extension to show/hide the widget appropriately
• No data is transmitted - only used for local site detection

Storage Permission:

• Stores your preferences and usage data locally
• Required for the extension to remember your settings
• All data remains on your device

Notifications Permission:

• Enables gentle check-in reminders
• Completely optional - can be disabled in settings
• No notification content is logged or stored

Active Tab Permission:

• Allows the extension to detect the current website
• Essential for time tracking functionality
• Does not access page content or user input

6. Children's Privacy

ScreenLimit is suitable for all ages and does not knowingly collect personal information from children under 13. Since no data is transmitted from the device, there are no special considerations for children's usage beyond general parental guidance on screen time.

7. Your Rights and Controls

• View your data: All usage statistics are visible in the extension popup
• Delete your data: Uninstall the extension to remove all data

If we make changes to this privacy policy, we will:

• Update the "Last updated" date at the top of this page
• Notify users through the extension if significant changes are made
• Continue to maintain the same privacy-first approach

We will never introduce data collection or external transmission without clear user consent and updated permissions.

9. Technical Details

9.1 How Site Detection Works

Data is stored in a simple JSON format locally:

• Daily usage totals
• Per-site time tracking
• User preference settings
• No personal identifiers or sensitive information

10. Open Source and Transparency

ScreenLimit believes in transparency:

• The extension code can be inspected in Chrome's developer tools
• All functionality is implemented client-side
• No obfuscated or hidden code
• Users can verify the privacy claims by examining the source
