Frequently Asked Questions
Everything you need to know about QR car decals, privacy security, and tandem parking etiquette.
Why is leaving a personal cell phone number on a car windshield risky in California?
In California, public phone numbers on windshields expose vehicle owners to prowler targeting ("bipping"), identity scraping, spam robocalls, and harassment. Under CCPA privacy principles, your personal phone number should never be exposed in public spaces. Nudgee replaces your phone number with an encrypted QR code.
How does Nudgee help drivers avoid $73-$90+ street sweeping fines in SF and LA?
Street sweepers in San Francisco (SFMTA $90+) and Los Angeles (LADOT $73+) ticket relentlessly. When neighbors or dog walkers spot an approaching sweeper, they scan your Nudgee decal. You get an immediate alert on your phone and can move your car before the citation officer arrives.
How does Nudgee solve apartment tandem parking in Los Angeles, SF, and San Diego?
Tandem parking is standard across California apartments. Nudgee allows tandem neighbors to ping each other in 2 seconds with quick messages like "Need to leave in 10 mins" without sharing personal phone numbers or calling each other at odd hours.
Does the person scanning my QR code need to install an app or register an account?
No app is required! Anyone with an iPhone or Android camera can scan your decal directly. The web notification interface loads instantly in their mobile browser, allowing them to notify you in 1 tap.
Can pranksters or random pedestrians spam notifications to my phone?
No. Nudgee incorporates an enterprise-grade Security Shield with 0.002-second rate-limiting and device fingerprinting. A vehicle cannot receive more than one notification burst within a 3-minute window, blocking malicious spam instantly.
Can I disable notifications when my vehicle is parked safely in my garage?
Yes. With one tap in your Nudgee dashboard, you can turn on "Do Not Disturb" (DND) mode. When active, scanners are notified that the vehicle is safely parked and notifications are temporarily paused.
How do I print a waterproof windshield decal, and how much does it cost?
Nudgee generates free 300 DPI high-resolution graphics designed for 4×6 photo prints. You can upload the image to CVS Pharmacy Photo ($0.39) or Walgreens Photo ($0.38) and pick it up same-day at any neighborhood California store.
How does Nudgee help EV drivers avoid Tesla Supercharger idle fees in Silicon Valley?
Tesla and Electrify America charge up to $1.00/min in idle fees. In busy Bay Area tech hubs, fellow EV drivers can scan your decal to politely alert you that your vehicle is fully charged or that someone is waiting for the plug.
How do I respond when someone scans my QR code?
When notified, you can tap preset one-touch responses such as "On my way! 3 mins" or "Be there in 5-10 mins". The bystander's screen immediately updates with your estimated arrival time, eliminating parking rage.
Is Nudgee completely compliant with California Consumer Privacy Act (CCPA)?
Yes. Nudgee enforces end-to-end anonymity. Neither your phone number, name, nor email is ever exposed to scanners or stored in publicly queryable records.
