How the shared network operates, what it is for, and what we expect from everyone on it.
This code governs the public network: the shared net that connects officers across sites and companies. Private team networks run under your employer’s communication policy. This code applies whenever you send to the shared network.
01 · Purpose
The shared network is an emergency and incident network for licensed security officers. It is there for the moments that matter: an attack under way, someone about to be hurt, someone dangerous moving in your direction or anyone else’s, a missing person, an incident unfolding near you. One press alerts the licensed officers around you: the few hundred metres where the next pair of trained eyes is standing.
You decide what the emergency is. You are trained to notice, and the network trusts your judgement.
This is mass communication for the people who keep others safe. One signal reaches every licensed officer around you at the same moment. Police advisories reach the net the same way. Nobody rings around; everybody who needs to know, knows at once.
It is a personal safety app. It keeps you aware of what is happening around you, it keeps you safe, and it keeps the community around you safer. That is the purpose, and everything else in this code follows from it.

02 · Membership
Because you are a licensed professional. Every officer on OnSiren holds a valid SIA licence, checked when you join and revalidated against the public register. Every account is a real, named person.
Your access is linked to your licence. If your licence lapses or is revoked, the app stops working for you.
Your account belongs to you, not your employer. It moves with your career, and you can delete it at any time.
Using the shared network means you agree to this code, and to the deal at the heart of it: you report. When you see something that puts people at risk, you alert the officers around you. You keep them safer, they keep you safer, and the public is safer for it.
The network holds you to the standard you already hold. Everything this code asks lines up with what is already expected of a licensed professional: the standards of behaviour the SIA expects of licence holders, the counter-terrorism awareness the industry trains for, and the duty everyone at work has to the safety of the people around them. Nothing here is new to you. The network gives the standard reach.

04 · Alpha One
Alpha One is the AI in the system, and it works for you. It gives you situational awareness: a briefing when you sign on, then what is happening around you and what is changing as the shift moves, so you are always aware. Through the shift there is no feed, nothing to scroll, nothing to keep checking: alerts reach you as notifications, and the voice channel you hear like a radio. Busy when something came through? Ask Alpha One for the summary when you are clear.
It also keeps the network worth listening to. Every alert is checked for relevance before it goes out. Something that does not help anyone beyond your site will not be broadcast. When the network speaks, it matters.
The same goes for images. Photos and videos shared to the network are checked by the AI before they go out. Anything inappropriate is blocked and never broadcast.

05 · Your data
OnSiren complies with UK GDPR. We collect the minimum we need and use it only for safety purposes the law recognises: preventing crime, responding to emergencies, protecting people.
What we record when you send. A signal, the place it was sent from, and the time. The system determines whether it will benefit others: if it will, it is forwarded to the officers who need it; if it will not, it is not broadcast. Either way it is logged, kept for a limited time, then deleted. The privacy notice sets out the full detail.
06 · Removal
False reports. Repeatedly sharing things that are irrelevant to the network. Abusive behaviour or foul language. Sharing inappropriate images or content. Misusing personal information. Any of these and your account is removed.
If you see something wrong on the network, report it: conduct@onsiren.com.
