Privacy Policy

What we collect, why we collect it, and the control you have over it.

Last updated October 15, 2026

This policy explains what SIREN (“we”, “us”) collects when you use the SIREN app on iOS or Android or visit trysirenapp.com, how we use it, and the choices you have. We do not sell your personal information, and we do not use it for third-party advertising.

Information we collect

Information collected automatically

How we use it

Location

SIREN is location-based, so it needs your location while you use the app. We store an approximate location, not your exact GPS coordinates. Signals are tagged with an area roughly a kilometre across, and other people see that a signal is nearby, never your precise position.

You can turn location access off in your device settings at any time. Without it, you won't be able to broadcast or see nearby signals.

Content moderation

When you post a public signal or a Clone, a thumbnail from the video and its caption are checked by an automated moderation service (OpenAI's moderation API) for content that breaks our rules. Flagged content may be hidden automatically and reviewed by us. Other users can also report content, and we may review reported content, including the account that posted it.

Who we share it with

We share information only with service providers that help us run SIREN, only for that purpose, and when required by law or to protect people's safety.

Content you broadcast publicly is visible to people nearby while it's live, and anything you post can be seen by the people you share it with.

How long we keep it

Beta waitlist

If you request beta access on trysirenapp.com, we store your email address, the time you signed up, the page you came from, your browser type, and a one-way hash of your IP address (used only to stop spam; it can't be turned back into your IP address). We use this to send you a confirmation, contact you about beta access, and manage invitations. We don't add you to marketing lists.

We keep waitlist entries until the beta ends or you ask us to remove you. To be removed, reply to any beta email or write to support@trysirenapp.com.

Your choices and rights

Depending on where you live, you may have additional rights under local law (for example, India's Digital Personal Data Protection Act, the GDPR, or US state privacy laws). Contact us to exercise them.

Children

SIREN is for people aged 17 and over, and the app checks this at sign-up. We don't knowingly collect information from anyone younger. If you believe a child is using SIREN, tell us at support@trysirenapp.com and we'll remove the account.

Security

Data is encrypted in transit, and access to our systems is restricted. No service is perfectly secure, but we work to protect your information and will notify you if a breach affects you as required by law.

Changes

If we change this policy, we'll update the date at the top. For significant changes, we'll let you know in the app or by email before they take effect.
