Welcome to a whole new level of fire protection like you’ve never seen before. Developed by a leading-edge team of scientists and fire detection engineers, The Flame Detector is the only product of its kind on the market today. Designed to detect flame, it can detect many home fires hundreds of times faster than traditional smoke alarms. Detect flame in seconds, alerting you to fire much faster and helping prevent fire from ever getting out of hand in the first place. How does a Flame Detector compare to a smoke alarm? Smoke alarms work by detecting small particles of combustion (smoke) that must travel into the smoke alarm’s sensing chamber before ever alarming. Depending on the location of the fire to the proximity of the smoke alarm, it can take tens of minutes before a smoke alarm is activated. The Flame Detector, on the other hand, constantly monitors for the presence of flame in your home, and the moment it detects unwanted fire, you’re notified. It’s that simple! The Flame Detector is beautifully designed to monitor spaces where a flame should never exist, like a child’s bedroom, playroom or even your garage. Thousands of home fires are started by children every year, and more than half of those fires originate in the bedroom. With a Flame Detector, the moment a child lights a match a loud alarm is produced and a push notification is sent to your smart device telling you exactly where the fire started. When dealing with fire, seconds truly count! With the Flame Detector, you can be made aware of flame instantaneously, preventing dangerous home fires from ever occurring.

They see that you're okay. Not where you are. Every other safety app answers one question, continuously: where is this person right now? That's a window, and once a window exists, somebody looks through it. On an ordinary Tuesday afternoon, when nothing is happening. TrustNet doesn't have a window. WHAT YOUR CONTACTS SEE EVERY DAY Your name, and one line: how recently your location updated. Not where you are. There is no map, because we never built one. At 2am your sister doesn't need to know which bar you're in. She needs to know your phone was alive four minutes ago. WHAT HAPPENS IF YOU GO MISSING Your phone quietly records a point when you meaningfully move. Those records are encrypted and stored away from your device, and only the most recent 3 days exist. A contact you named can request them. Their identity is verified by email, and you are notified that they asked. That is the only path to the places you have been, and every use of it leaves a record. IF YOU CAN REACH YOUR PHONE Open TrustNet and send an SOS. Your location goes straight to your contacts, in their app and by email. It does require opening the app. Every panic button has that limit and we would rather say so than pretend otherwise. WHY IT IS BUILT THIS WAY The people who need finding usually cannot press anything. Asleep, hurt, held, or simply not home yet. A protection that depends on you acting in the worst moment of your life is not much of a protection. WHAT WE WILL NEVER DO - Sell or share your location data - Give your contacts a live map, or any way to check on you casually - Release your records without a verified request from someone you named, and without telling you - Keep your records beyond 3 days - Use a real emergency in our marketing And what we will not pretend: we do store your location. Regularly. That is the product. The promise is not that nothing is kept. It is that nobody gets to look. Delete your account and every location record whenever you want.
