Mustr — School Safety Comms

Mustr is the K-12 emergency communications platform built on the "I Love U Guys" Foundation's Standard Response Protocol (SRP) and Standard Reunification Method (SRM). It puts the same five protocol triggers — HOLD, SECURE, LOCKDOWN, EVACUATE, SHELTER, plus ALL CLEAR — that your district already trains on into every staff member's pocket, with the safety rails a real K-12 deployment needs. WHAT MUSTR DOES • SRP-native triggers, not generic alerts. The exact protocol your staff trains on, with a 3-second press-and-hold gate so a real LOCKDOWN can't be triggered by an accidental tap. Drills are a regular tap and are unambiguously labeled. • Realtime + push + SMS, in parallel. Server-Sent Events drive the live admin and mobile UI in roughly 125ms. Expo Push wakes phones in pockets. Twilio SMS catches stale tokens. • "I'm safe" check-ins per staff member, per event. The Command tab shows live counts of who has and hasn't checked in, by school and by zone, so the Incident Commander knows immediately who needs to be located. • Standard Reunification Method on a tablet. Encrypted guardian list, government-ID verification, photo capture for chain of custody, append-only release ledger. • Nine NIMS-aligned ICS roles adapted for K-12 — Incident Commander, PIO, Liaison, Safety Officer, Operations, Planning, Logistics, Finance/Admin, Reunification Coordinator. • Complete incident export. Every trigger, attendance report, zone report, ICS assignment, staff check-in, and message is timestamped and downloadable as a PDF the moment the event closes. • Live SIS sync — PowerSchool, Infinite Campus, FACTS. PRIVACY & COMPLIANCE • FERPA-aligned by design. Mustr operates as a school official with a legitimate educational interest under 34 CFR §99.31(a)(1)(i)(B). • Per-district AES-GCM encryption seals guardian PII at rest. • Tenant isolation top to bottom. • 5-role RBAC re-enforced on the server inside every state-changing call. • Right of access (FERPA export) and right to be forgotten with a 24-hour cancel window. SAFETY DISCLAIMER Mustr is NOT a 911 replacement. In any real emergency, call 911 first. Mustr coordinates the response that follows. The app shows a mandatory "call 911 first" acknowledgement on first launch. WHO MUSTR IS FOR Mustr is intended exclusively for K-12 district staff (administrators, teachers, safety teams, reunification coordinators). Each district provisions its own users; there is no public sign-up. LEARN MORE mustrk12.com — privacy policy, terms of service, request-pilot form, and account deletion form.
