N-WatchEmergency alerts for your neighbourhood

Small, trusted groups. Known managers. Post-quantum encryption. Safety by design.

The N-Watch trust model

N-Watch is built on one core principle: every end user has a group manager they know and trust.

No matter how many groups exist across the country, your experience as a member never changes — you belong to a small, vetted group managed by someone in your community. Your manager controls who joins, who stays, and who is removed. There is no global feed, no strangers, and no algorithm deciding who sees your alerts.

This structure is the primary design decision behind N-Watch, and it will never be compromised. The emergency alerting function is critical, but the curated, human-scale group is what makes it safe.

How it works

  1. A manager creates a neighbourhood group and generates an invite code
  2. Members install the app, sign in with Google or Apple, and join using the code
  3. In an emergency, a member taps Alert — one confirmation, instant fan-out
  4. Every active member receives a critical-priority push notification with encrypted location
  5. GPS coordinates are tappable — one tap opens the location in your maps app

Safety by design

N-Watch is built with data minimisation and human-scale trust at its core:

  • Your group manager knows you — every member is personally vetted
  • No home addresses stored on any server — encrypted on-device only
  • No continuous location tracking — GPS is opt-in, per-alert only
  • No social features or engagement loops — just safety
  • All privileged actions verified server-side — the app cannot be tricked
  • Managers can pause or ban members who misuse alerts
  • The sender's own phone stays silent when they trigger an alert, protecting them if under duress
