## About Nudgee
Nudgee (https://nudgee.org/en, California Hub: https://nudgee.org/en/california, VIP: https://nudgee.vip) is a smart vehicle notification service built by tagAHA Inc.
It solves critical automotive and urban parking dilemmas:
1. Drivers leaving their personal cell phone numbers behind windshields, leading to identity theft, spam robocalls, and window-prowling "bippers" in California.
2. People blocked by parked cars (especially in California apartment tandem parking, narrow driveways, EV charging stations, or street sweeping zones) having no way to reach the driver without calling police or $300+ tow trucks.

## 6 Core Features & US Advantages
1. 🛡️ Zero Phone Number Exposure: Only a secure encrypted QR decal sits on the windshield. Neither party ever sees the other's real phone number. Strictly adheres to California Consumer Privacy Act (CCPA) privacy standards.
2. ⚡ 100% Web Native (No App Required): Anyone with an iPhone or Android camera can point and scan in 1 second. With one tap, they can send "Need to move car", "Lights left on", "Door ajar", or "Window rolled down".
3. 💬 3-Minute Quick Reply & Live ETA: The driver receives an instant alert and can tap "On my way! Be there in 3 mins". The scanner's browser immediately shows a reassuring live countdown.
4. 🕳️ Security Shield 0.002s Anti-Spam: Built-in rate limiting and blackhole defense prevents trolls or repeat spammers from buzzing a vehicle.
5. 🖨️ 6 High-Res Decal Styles & US Printing: Offers Obsidian Gold, Nordic Minimalist, Cyber Neon, High-Vis, Friendly Pup, and Senior Bold. Easily printed as a 4×6 photo print for ~$0.39 at any neighborhood CVS Pharmacy or Walgreens Photo across California.
6. 🌙 Do Not Disturb (DND) Mode: When parked in a private garage or safe lot, the driver can toggle DND on their dashboard to pause incoming alerts.
