  FolScan is a privacy-first browser extension designed for users who want to analyze their Instagram growth without compromising their account security. Built with a focus on transparency and safety, FolScan allows you to understand follower changes — all without ever asking for your Instagram password or the Instagram data leaving your browser. 
  
  Able to analyze your own account, public accounts and private accounts that you follow.
  
  Features:
  New Followers: Displays users who have followed the target account since the last scan.
  Lost Followers: Identifies users who have unfollowed the target account.
  New Followings: Shows new accounts the target account has started following.
  Unfollowed (By You/User): Lists accounts the target has stopped following.
  Not Following Back: Identifies accounts that the target follows but who do not follow the target back.
  Summary Header: Displays current follower and following counts, with colored arrows (▲/▼) and change amounts relative to the previous scan.
  Mutual: Lists mutual followers.
  Growth Analytics Dashboard (Premium): Interactive line graphs visualize follower and following trends over time. Track 11 distinct metrics including New/Lost counts and Username changes across your entire history.
  Block Check Tool (Premium): Sophisticated detection system to identify if a profile has blocked the viewer.
  Username Change Tracking (Premium): Explicitly identifies users who have changed their handle between scans, ensuring you never lose track of a numeric ID.
  
  User Metadata Indicators: Each user in the report is tagged with status icons:
  🔒 Private: The account is set to private.
  ✅ Verified: The account is verified by Instagram.
  📤 Requested by You: You have a pending follow request to this account.
  📥 Requested You: This account has a pending follow request to you.
  
  Report History & Persistence: Quick access to previous scans via a dropdown menu. FolScan automatically remembers and displays the last generated report for each username, including a timestamp of when it was run.
  Data Export: Download full growth history or specific scan results as formatted CSV reports for external analysis.
  
  Why Users Should Install FolScan
  In an era of invasive apps, FolScan stands out by prioritizing the user's account health:
  
  Zero-Password Security: We use your existing, active browser session. FolScan never sees, stores, or transmits your login credentials.
  
  Safe Analysis: The extension processes data in controlled batches with timed intervals to maintain reliable performance during extended scans.
  
  Local Data Ownership: Your follower data is stored locally in your browser's secure storage. We do not maintain a cloud database of your social connections.
  
  Professional Exporting: Perfect for creators and small businesses, FolScan allows you to export your analysis into clean CSV reports for further study in Excel or Google Sheets.
  
  How to Use:
  Navigate to Instagram.com and ensure you are logged in.
  
  Open the FolScan extension from your toolbar.
  
  Run a scan to establish your baseline.
  
  Return anytime to see a detailed report of how your community has changed!
