Terms of Service

OnSiren is operated by Onsiren Limited, a company registered in England and Wales (“OnSiren”, “we”, “us”). By creating an account or using the app, you agree to these terms, to our Privacy Policy, and to the Code of Practice, which forms part of these terms. If you do not agree, do not use the service.

To use OnSiren you must:

• hold a valid licence from the Security Industry Authority (SIA);
• be at least 18 years old;
• register in your own, real name; and
• keep one account, for yourself only.

Your access is linked to your licence. If your licence lapses, is suspended, or is revoked, you must stop using the network, and we can end your access. Your account belongs to you, not your employer, and moves with your career.

When you sign up, we check your SIA licence number against the SIA’s public register. You then finish verifying yourself in the app: a photo of your licence card, a face-liveness check (with your explicit consent, see the Privacy Policy), and your email address. You can use OnSiren while you finish, but do it within the time the app shows you. If that time runs out first, you can still open the app and read what’s there, but you can’t go on duty, join a channel, transmit, send alerts or use Alpha One until you finish.

You agree to give accurate information during registration and to keep your account details up to date. You can be signed in on one device at a time: signing in on another device signs you out of the first. You are responsible for what happens under your account; tell us immediately at contact@onsiren.com if you believe it has been compromised.

The network depends on connectivity, device battery, and officers being nearby and available, none of which is guaranteed. You must not rely on OnSiren as your only means of raising or receiving an emergency alert.

The Code of Practice sets the standard for conduct on the network. In short, you must not:

• send false, misleading, or malicious reports;
• name or accuse individuals: report what you saw, not who you think did it;
• use the network for abuse, harassment, foul language, or anything other than its safety purpose;
• share inappropriate, unlawful, or infringing content;
• misuse personal information you encounter on the network;
• send workplace records to the shared network, such as your employer’s incident reports, CCTV or body-worn camera footage, or a photo or screen recording of any of these: describe what you saw yourself instead;
• use the network to hunt for, harass or publicly shame anyone;
• use the network to watch, identify or disrupt people taking part in a peaceful protest (a specific, current risk to safety there can still be reported);
• interfere with the service: no probing, scraping, reverse engineering, automated access, or circumventing verification or moderation;
• share your account, or use the network while your licence is not valid.

You keep ownership of the content you send: alerts, voice transmissions, messages, photos. So the network can work, you grant us a non-exclusive, royalty-free, worldwide licence to host, relay, transcribe, translate, moderate, and display that content to the officers it is meant for, and to keep the operational records described in the Privacy Policy. This licence exists to operate, secure, and improve the service. We do not sell your content or use it for advertising.

You are responsible for what you send. We automatically check what you type in alerts and messages for abusive words and, where that check is on, the photos you send for unsafe content. Anything you send may be blocked or removed. We may act on anything that breaches these terms or the Code of Practice.

If you see something that breaks these rules, report it: press and hold the message in the channel chat. You can also block an officer, which hides their messages from you.

OnSiren uses AI to turn radio traffic and voice notes into text, to translate them into English, and to check the photos you attach. The processing the service needs is set out in the app when you join, and in the Privacy Policy.

Alpha One, the assistant in the app, answers your questions by voice or text and can summarise what has happened on your channel. It is optional: switch it on or off in Settings → AI & your data. Turning it off doesn’t stop the checks on what you send. Where Alpha One offers to prepare something for you, such as an alert or a change of channel, nothing is sent or changed until you confirm it yourself.

AI output can be incomplete or wrong, and so can the public and third-party information in your briefings. It is informational only. It is not professional, legal, or safety advice, and it is never a substitute for your own training and judgement or for official instructions. Verify anything critical before acting on it.

How we handle your personal data, including your location, communications, licence details, and the biometric verification check, is set out in the Privacy Policy.

You can leave at any time: delete your account in the app (Settings → Account → Delete my account) and your data goes with it, as described in the Privacy Policy. If some of your records have to be kept for a legal reason, such as an open investigation, the app will tell you, and you can delete your account once they no longer need to be kept.

We can suspend or remove your account if you breach these terms or the Code of Practice, including false reports, repeated irrelevant broadcasts, abusive behaviour, inappropriate content, or misuse of personal information; if your SIA licence is no longer valid; or if we must do so to protect the network or comply with the law. While your account is suspended you stay signed in and can contact us, but you can’t go on duty or use the network. Where reasonable we will tell you why.

Sections that by their nature should survive termination (including Content you share, Intellectual property, Disclaimers and liability, and Changes to these terms) do so.

The app, the network, Alpha One, and everything that makes them up (software, design, branding, and content we created) belong to Onsiren Limited or our licensors. We grant you a personal, non-transferable, revocable licence to use the app for its intended purpose while you have an account. You may not copy, modify, distribute, or create derivative works from any part of the service except as the law allows.

The service is provided “as is” and “as available”. We work hard to keep it running, but we do not guarantee that it will be uninterrupted, error-free, or that any alert will reach any particular officer at any particular time.

Nothing in these terms excludes or limits liability that cannot be excluded under the law of England and Wales. This includes liability for death or personal injury caused by our negligence, or for fraud. Subject to that, we are not liable for losses that were not a foreseeable result of our breaking these terms, for losses connected with your business or employment, or for events outside our reasonable control. Our total liability to you is limited to £100 or the amount you paid us for the service in the 12 months before the claim, whichever is greater.

You download OnSiren through the Apple App Store or Google Play, and their terms also apply to the download. These terms are between you and Onsiren Limited only, not with Apple Inc. or Google LLC. Apple and Google have no obligation to provide maintenance or support for the app and are not responsible for it or its content; addressing any claims about the app is our responsibility. Apple and its subsidiaries are third-party beneficiaries of these terms and may enforce them against you. You confirm you are not in a country subject to a relevant government embargo and are not on any restricted-parties list.

We may update these terms as the service evolves. We will update the date at the top and, for significant changes, tell you in the app before they take effect. We keep earlier versions of these terms, and we’ll send you the version that applied on any date you ask about. If you keep using OnSiren after a change, the updated terms apply; if you do not agree, stop using the service and delete your account.

These terms are governed by the law of England and Wales, and the courts of England and Wales have jurisdiction over any dispute. If you live in Scotland or Northern Ireland you may also bring proceedings there. If any part of these terms is found unenforceable, the rest remains in force.
