Terms & Conditions

Last updated: July 2026

1. Acceptance

By installing or using Tsunami Shield ("the app"), you agree to these terms. If you do not agree, do not use the app. The app is operated by Smart Send Australia Pty Ltd, trading as Grand Plan Enterprise. References to "we", "us" or "our" refer to Smart Send Australia Pty Ltd (trading as Grand Plan Enterprise).

2. Nature of the service

Tsunami Shield aggregates publicly available alerts and seismic data and surfaces them on your device. It is informational only and is not an official warning system. Coverage, accuracy and timeliness depend on upstream sources, your network connection, and your device.

3. No warranty

The app is provided "as is" and "as available" without warranties of any kind, express or implied, including merchantability, fitness for a particular purpose, or non-infringement. We do not warrant that alerts will be delivered, will be accurate, or will arrive in time to be useful.

Alert delivery also depends on your subscription being active and in good standing. No alerts will be delivered to devices with an expired or cancelled subscription, regardless of network conditions or device readiness.

4. Limitation of liability

To the fullest extent permitted by law, the operators are not liable for any direct, indirect, incidental, consequential or punitive damages arising from missed, delayed, inaccurate or unavailable alerts, or from decisions made on the basis of information shown in the app.

This limitation expressly includes any failure to receive alerts resulting from a lapsed, cancelled, or otherwise inactive subscription; a user's failure to maintain current payment details; or the suspension of access following subscription expiry.

5. Your responsibility

You remain responsible for your own safety. Always follow local civil-defence sirens, broadcasts and instructions, and treat natural warning signs (strong or long shaking, the sea rapidly receding or rising, a loud roar from the ocean) as authoritative warnings even when the app is silent.

6. Location monitoring limitations

Tsunami Shield monitors alerts based on the locations you have explicitly configured — your saved locations, Home Country Protection (which uses real-time GPS when a warning is issued in your home country), and any countries you add to Travel Mode.

When traveling internationally, you must manually add destination countries to Travel Mode to receive alerts for those areas. Tsunami Shield does not automatically detect your presence in a foreign country. If you do not add a country to Travel Mode, the app cannot alert you to tsunami threats in that country, even if a warning is issued while you are there. This is your sole responsibility as a user of the app.

Home Country Protection provides GPS-based alerts when a tsunami warning is issued anywhere in your home country and your device's location falls within the alert's affected zone. This feature requires location permission to be granted and active on your device. It does not extend to countries other than your designated home country.

7. Subscription

Premium features are offered on a subscription basis ($2.99/month or $19.99/year, with a 3-day free trial). All prices are in USD. Subscriptions auto-renew unless canceled at least 24 hours before the renewal date. Manage or cancel your subscription from your platform's app store.

If your subscription expires, is cancelled, or is not renewed for any reason, your access to alert notifications will be suspended immediately upon expiry of the subscription period. The application will display a notice informing you that your subscription has ended, and you will not receive tsunami warnings, earthquake alerts, or any other safety notifications until a valid subscription is restored.

It is your sole responsibility to ensure your subscription remains active and that your payment method is current and valid. Smart Send Australia Pty Ltd accepts no liability for any loss, injury, or damage arising from a failure to receive alerts where that failure is attributable to a lapsed, cancelled, or otherwise inactive subscription.

8. Changes

We may update these terms from time to time. Material changes will be surfaced in-app. Continued use of the app after a change constitutes acceptance of the updated terms.

9. Contact

Questions about these terms can be sent to hello@grandplanenterprise.com or lodged via the Contact form on our site Tsunamishield.tech. The app is operated by Smart Send Australia Pty Ltd (trading as Grand Plan Enterprise).
