Core features and Pro

The first whistle, steady rear flashlight, flashing SOS, basic alarm, help, preparation, emergency-number, and sharing tools are free. The optional one-time Pro purchase unlocks only three additional whistle choices and ad-free use.

Privacy

Whistle Sound does not require an account. Emergency contacts, medical card details, safe meeting points, settings, and incident logs that you enter manually are stored on your device and are not uploaded to a developer-owned server. Calling, messaging, and sharing screens open only after your action.

The free version may show non-personalized ads only in non-critical preparation and settings areas. Ads are not shown during an active alarm, SOS, help card, location sharing, emergency calling, or rescue mode. When Pro is active, the app does not request ads. Detailed data-handling information is available in the in-app Privacy Center and privacy policy.

Important: Whistle Sound is not an earthquake detection or early warning system. It does not replace official emergency services, automatically report an incident, automatically send messages, or guarantee rescue. If you are in immediate danger, call the official emergency number for your country.
