Privacy Policy

Effective date: July 11, 2026

Sirens (“the app,” “we,” “us”) displays public emergency-incident information for Montgomery, Bucks, and Chester County, Pennsylvania. We are built to collect as little as possible. This policy explains what we collect and why.

The short version

• No account. We don’t ask for your name, email, phone number, or contacts.
• No analytics, no advertising, no third-party trackers.
• We never sell your data.
• The only data that leaves your device is a push-notification token and a watch-area location you choose — and only if you turn on notifications.

Information we collect

Location (only while using the app)

If you grant location access, your device location is used on your device to show how far away incidents are and to center the map near you. Your continuous location is not sent to our servers.

Watch area (only if you enable notifications)

If you turn on incident notifications, you choose a “watch area” — a center point, a radius, and the incident categories you care about. We send that watch-area center, radius, and category preferences, together with a push-notification token issued by Apple, to our server so we can notify you when a matching incident occurs. If you set the watch area to your current location, that location is included.

Push-notification token

To deliver notifications, Apple issues a device token that we store on our server and associate with your watch area. It does not identify you personally. When you disable notifications or uninstall the app, the token is removed; invalid tokens are also deleted automatically.

Information we do not collect

• No name, email address, phone number, or account.
• No advertising identifiers, analytics, or behavioral tracking.
• No browsing history or contacts.

How your information is used

Solely to operate the app’s features: showing incidents near you and sending the notifications you request. Nothing else.

Third-party services

• Apple — Push notifications (APNs) and weather (WeatherKit) are provided by Apple and subject to Apple’s privacy policy. Weather for your area is provided by Apple Weather and its data sources.
• Cloudflare — Our server runs on Cloudflare, which processes requests to deliver incident data and notifications.
• Public data providers — Incident data comes from the public-safety feeds of Montgomery, Bucks, and Chester Counties. Weather alerts come from the U.S. National Weather Service.

We do not control, and are not responsible for, the accuracy or availability of third-party data.

Data retention

Watch-area and notification-token records are kept only while notifications are enabled. Disabling notifications or uninstalling the app removes your record. Incident data shown in the app is public information and is not linked to you.

Children

Sirens is not directed to children under 13 and does not knowingly collect information from them.

Your choices

• Turn notifications off at any time (in the app or iOS Settings) to stop sending and to remove your watch-area and token record.
• Turn location off in iOS Settings; the app still works, without distance and “near me” features.

Changes

We may update this policy; the effective date above reflects the latest version.
