• Managing and organizing your highlights in the sidebar
• Saving your personal preference settings

We do NOT:

• Upload any data to servers
• Share data with third parties

4. Data Storage

All data is stored in your local browser's IndexedDB database. Data is NOT:

• Synced to the cloud

5. Permission Usage

5.1 Host Permissions (host_permissions: "<all_urls>")

PageMark needs to run on all web pages to:

• Detect text selection on any webpage
• Display highlight annotations visually on web pages
• Restore previously created highlights when you revisit pages
• Use DOM path positioning to accurately locate and display highlighted text

Data Collection: We do not collect any web page content or browsing history. We only store highlight data that you actively create (text, position, color, tags, notes). All data is stored locally in your browser only.

5.2 activeTab Permission

Used to:

• Get the current active tab's URL to associate highlight data with specific web pages
• Open the sidebar panel in the current active tab when you click the extension icon
• Navigate to the corresponding tab and scroll to the highlight position when you click a highlight card in the sidebar

Data Usage: We only get the current active tab's URL (to associate highlight data). We do not access other tab information or track your tab switching behavior.

5.3 scripting Permission

Used to:

• Inject content scripts when web pages load to:
  • Listen for text selection events
  • Create and manage highlight elements
  • Handle user interactions (clicking highlights, showing floating buttons, etc.)
• Dynamically execute scripts when needed to restore highlight annotations

Data Usage: We only execute scripts on web pages you visit. We do not modify the original page content, do not access sensitive information on pages, and only process text that you actively select and highlight.

5.4 sidePanel Permission

Used to:

• Display the sidebar interface, providing a user-friendly management interface for:
  • Displaying a list of all highlight annotations
  • Providing search and filter functionality
  • Allowing users to edit, delete, and manage highlight annotations
  • Displaying statistics and usage tips
• Centrally manage all highlight annotations in the sidebar for a better user experience

Data Usage: The sidebar only displays highlight data stored locally on your device. It does not access any external data and does not transmit data to external servers.

5.5 storage Permission

Used to:

• Store highlight annotation data you create in local IndexedDB (via chrome.storage API), including:
  • Highlight text content
  • Highlight position information (DOM paths)
  • Highlight colors, tags, and notes
  • Highlight timestamps and sorting information
• Save your personal settings, such as default highlight color
• Pass messages between content scripts and the sidebar (when the sidebar is not open)

Data Usage: All data is only stored in your local browser's IndexedDB. Data is not synced to the cloud, not uploaded to any server, and will be deleted when you clear browser data.

6. Data Deletion

You can delete data at any time by:

• Deleting individual highlights in the sidebar
• Using the "Clear Highlights" feature to delete highlights in bulk (current page or all pages)
• Clearing browser data, which will delete all data

When you delete highlights, the data is permanently removed from your local browser storage and cannot be recovered.

• ✅ No Data Upload: No data is uploaded to external servers
• ✅ No Tracking: We do not track any user behavior
