Alertplates is a private, anonymous tool that helps protect vehicle owners through community awareness. If someone sees possible vandalism or concern around a parked car, they can send a preset alert to the owner using only the visible license plate. Alert options: • Suspicious Person(s) • Damage or Tampering Alerts are anonymous, predefined, and only sent to users who’ve opted in with their own plate. Users can also pin their regular parking areas to receive any descriptive alerts within those zones. The Awareness Map lets users share short by lived 12 hour area alerts when a plate isn’t visible — like a car that looks tampered with. Anyone who’s pinned that area will get notified. All map alerts are brief, factual, and based on what’s observed — keeping the focus on safety, not opinions. Each account includes one plate for free, with an optional upgrade for more. No messaging, no personal data — just simple, discreet alerts that could help prevent harm. Because safety is shared. Today it’s someone else’s car. Tomorrow, it could be yours.
