  description

  Are you tired of receiving fake virus alerts, click-bait advertisements, and adult content notifications on your desktop? Deceptive websites often trick you into clicking "Allow Notifications" using fake captcha prompts or urgent security warnings. Once allowed, they flood you with annoying spam popups.
  
  NotiSpam Cleaner is a privacy-first, lightweight tool designed to scan and clean notification settings in Google Chrome, protecting you from notification abuse.
  
  KEY FEATURES
  - Scanner: Instantly scans your allowed notifications list against browsing history, bookmarks, and active tabs.
  - Smart Whitelisting: Automatically separates allowed sites into "Trusted" (like Google, Slack, Teams) and "Suspicious/Unknown" so you know exactly which sites are safe.
  - One-Click Clean: Revoke permissions from all suspicious websites at once while keeping your trusted ones intact.
  - Real-time Protection Guard: Monitors notification permissions dynamically. If an unknown or suspicious site gets allowed, NotiSpam Cleaner raises an instant alert so you can undo/block it with a single click.
  - 100% Privacy-First: All scans, checks, and blocks are done locally on your machine. Absolutely zero data is collected, stored, or sent off-device.
  
  HOW TO USE IT
  1. Click the NotiSpam Cleaner icon in your toolbar.
  2. Click "Scan Allowed Sites" to analyze notification permissions.
  3. Review "Suspicious / Unknown" sites and click "Clean All Suspicious Sites" to block them.
  4. Keep the "Real-time Guard" toggle active to get alert popups if you accidentally allow a suspicious site in the future.
  
  IMPORTANT NOTES & LIMITATIONS
  - Not an Adblocker: This extension specifically blocks annoying popups generated through Chrome's native push notifications. It is not designed to block general web page advertisements (like banners or video ads).
  - Technical Limitation: Due to Chrome security constraints, extensions cannot retrieve a bulk list of all custom notification settings. NotiSpam Cleaner discovers sites by cross-referencing allowed rules with your local history, bookmarks, and open tabs. Very old allowed sites that are no longer in your history or bookmarks may not be scanned. You can view the full raw database link inside the extension to review all rules manually.
