Your own fallback communication tool.

Keep your critical people connected when networks fail or aren’t wanted.

When mobile networks, Wi‐Fi or cloud tools fail, communication in your hospital, school, plant or municipality shouldn’t stop. Allo gives you a local message network you control, so your most important people can still send and receive messages even if telecom and internet are completely down.

When networks fail,
you’re suddenly blind

Most critical communication today depends on fragile, centralized networks: mobile, Wi‐Fi, PBX, Teams, email. They work great until they don’t.

OUTAGES &
OVERLOADS

During storms, cyber incidents, drills, protests or
big events, networks can fail, jam, or be shut off.

AD-HOC
FAILBACKS

In those moments, people scramble to use WhatsApp, hotspots and phone trees that don’t scale and aren’t under your control.

UNACCEPTABLE
RISK

In a real crisis, losing contact with key teams and
partners is simply not an option.

Allo adds a simple, robust layer next to your existing tools. It doesn’t replace your phones, email or Zoom; it makes sure you can still talk when they’re gone.

FOR NON‐TECHNICAL READERS

Allo is a set of small devices plus an app that create your own local network for text and short voice messages. Your critical people can keep talking to each other, even if telecom and internet are completely down in your area.

FOR TECHNICAL READERS

Allo devices form a local, encrypted network that runs on hardware you own. Core messaging works off‐grid by default: no SIM, no Wi‐Fi and no cloud dependency. We keep metadata to a minimum and document the limits clearly (range, topology, battery).

Operations &
crisis leaders

Hospital operations managers, plant supervisors, heads of safety/security, municipal crisis coordinators. Keep critical shifts, wards, control rooms and security in sync when regular networks fail.

Public sector leadership

Mayors, crisis teams and safety regions that need a local backbone to connect with relevant stakeholders like hospitals and utilities when regular networks are unavailable.

Privacy‐first
groups

Activists, journalists and privacy communities that want local‐only coordination without depending on phone numbers and big tech cloud platforms.

How to implement..

From plan to practiced fallback in three steps:

You don’t need a big project to get started. We help you set up a small, focused pilot with your critical team and grow from there.

  • Map your critical people, spaces and work through IFTTT scenarios so you have a clear plan. Our back-end configurator can help you with that.

  • We ship Allo devices for your pilot team. You configure your plan in the Allo web application to get a clear contacts, channel and settings per device. Then you hand out your devices, pair them with phones using the Allo app and run a short, hands‐on training so everyone knows when and how to use the fallback layer.

  • You use Allo in drills, exercises and real events. Together we refine your configuration in terms of placement, roles and protocols until your fallback feels as natural as your primary systems.

What changes when you have a real fallback

With Allo in place, you stop hoping networks will hold and start owning your last line of communication.

Clear, practiced fallback

Everyone in your critical team knows how to switch to Allo when phones and Wi‐Fi go down.

Local loop you control

Crisis teams, ward leads, directors and their key partners stay in touch via a network that lives on your own devices and sites.

Realistic drills

Exercises stop feeling like theatre. You can safely simulate “no mobile / no Wi‐Fi” without losing coordination.

Calmer incidents

When something breaks, you don’t waste the first 20 minutes figuring out how to talk—you just switch to your fallback and get to work.

Not having a fallback doesn’t just create operational risk -it shows up in every debrief and evaluation.

Blind spots of 20–30 minutes or more at the start of an incident.

Ad‐hoc WhatsApp groups, hotspots and phone trees that nobody owns.

Crisis reviews full of “we couldn’t reach X” and “we assumed phones would work.”
