Privacy Policy

This policy explains how Idea Heron's apps handle your information. It applies to Tremor and to this website.

Data collect

None. Tremor does not collect, transmit, or store any personal data. Idea Heron does not operate user accounts and has no way to identify you.

Location

Tremor can use your location to center the map on you, show your distance and bearing from an earthquake, and deliver alerts for quakes near you. This is entirely optional — the app works without it.

When granted, your location is used only on your device. It is never sent to Idea Heron or to any third party, and it is not stored beyond what the operating system uses to fulfill these on-device features. You can revoke location access at any time in the iOS or macOS Settings app.

Notifications

If you enable alerts, Tremor uses Apple's notification system to tell you about significant or nearby earthquakes. Notification preferences are stored on your device. No notification data is sent to Idea Heron.

Earthquake data

To show seismic activity, Tremor fetches publicly available earthquake data from third-party feeds: the U.S. Geological Survey (USGS), the European-Mediterranean Seismological Centre (EMSC), the Japan Meteorological Agency (JMA), and GeoNet. These are ordinary network requests for public data; Tremor does not send your personal information to these services. To improve place names, Tremor may use Apple's geocoding service, which is governed by Apple's privacy policy.

On-device storage

Tremor stores your app preferences (such as filters, units, and alert settings) and a local cache of recent earthquake events on your device, so the app works quickly and remembers your choices. This data stays on your device and is removed if you delete the app.

Tracking and third parties

Idea Heron does not track you across apps or websites. Tremor contains no advertising, no analytics, and no third-party tracking SDKs. Idea Heron does not sell or share any data, because none is collected.

Children's privacy

Idea Heron's apps do not collect personal information from anyone, including children.

This website

IdeaHeron.com does not use cookies or analytics to track visitors. Goodbye, annoying cookie prompts!
