Presence over phones. We are the most connected generation in history, and the loneliest. Phones promised connection and delivered rooms full of people looking down. NIX exists to challenge that. We believe people are better off present: talking, cheering, actually in the moment with the people around them. So we build tools that make putting the phone away the easy, rewarded default instead of a punishment. For schools, that is one platform with two ways to go phone-free. A SIMPLER PHONE-FREE SCHOOL DAY Many states now require phones to be put away for the entire school day. NIX was built to make that day simpler, more cost-effective, and more effective than pouches, bins, or collection caddies. Students leave their phones at home or in the car. Staff scan the student ID badges students already carry, and NIX verifies each phone was actually left outside the building and logs compliance automatically. Nothing to buy, distribute, or replace, and nothing confiscated: the phone simply never comes in. REWARD PRESENCE AT EVENTS At games, dances, and campus events, students choose to leave their phones behind and earn a real reward on the spot: scan your ID at the door, NIX confirms your phone is away, and a coupon lands instantly. Showing up present, not scrolling, finally pays. HOW THE VERIFICATION WORKS 1. Leave your phone in your car, in your dorm, or at home. 2. Scan your school ID badge at the door. 3. NIX checks whether your phone is inside or outside the area and confirms you are phone-free. Real presence, not the honor system. Same app, same dashboard. Your school decides how NIX is used. WHY NIX - Positive, even when required. Nothing is confiscated and nothing is locked in a pouch. At events, students opt in and earn rewards. During the school day, the phone simply stays out of the building. Presence is worth more than a phone, and the whole platform is built on that. - No pouches. No new hardware. No manual check-in. Just the student ID badge you already carry. - Verified, not assumed. A geofence plus your ID scan confirms the phone is actually away. - Built with schools. NIX fits how schools already work, from existing ID badges to the staff running the door. YOUR PRIVACY NIX checks whether your phone is inside or outside an area at scan time. That is it. We keep a single, most-recent location reading. No location history, no trail, never for advertising, never shared. Delete your account and all your data anytime from your profile. Phones can wait. The people around you cannot. NIX makes presence the rewarded default.
