Terms of Service

1. Agreement to Terms

These Terms of Service ("Terms") constitute a legally binding agreement between you ("you" or "your") and Ghost Systems ("we," "our," or "us"), operating as Alertra. By accessing or using the Alertra website at alertra.app, the Alertra mobile application, and any related services (collectively, the "Service"), you agree to be bound by these Terms.

If you do not agree to these Terms, you must not access or use the Service. We reserve the right to modify these Terms at any time. Changes will be effective immediately upon posting. Your continued use of the Service after any modifications constitutes your acceptance of the revised Terms.

2. Description of Service

Alertra is a disaster monitoring and alerting platform developed by Ghost Systems. The Service provides:

• Real-time earthquake activity monitoring based on data from the U.S. Geological Survey (USGS).
• Localized threat assessments and risk scores derived from proprietary algorithms applied to public seismic data.
• Historical earthquake trend analysis and data visualization.
• Push notification alerts for seismic events near user-specified locations.
• General earthquake preparedness and safety information.

3. Important Disclaimers

3.1 Data Accuracy

The earthquake data displayed on the Service is sourced from the USGS and other public agencies. While we strive to present this data accurately and promptly, we make no guarantees regarding:

• The completeness, accuracy, or timeliness of earthquake data.
• The accuracy of threat scores, risk assessments, or magnitude estimates.
• The continuous, uninterrupted availability of the Service.

Earthquake data is inherently preliminary and subject to revision by the USGS. Magnitude, location, and depth values may be updated after initial reporting.

3.2 No Professional Advice

The information provided through the Service does not constitute professional geological, seismological, engineering, or emergency management advice. The safety tips and preparedness information are general guidelines and may not account for your specific location, building structure, or circumstances.

3.3 Alert Delivery

Push notification alerts are delivered on a best-effort basis. Alert delivery depends on factors outside our control, including your device settings, network connectivity, operating system restrictions, and third-party push notification infrastructure. We do not guarantee that alerts will be delivered within any specific timeframe or at all.

4. Acceptable Use

You agree to use the Service only for lawful purposes and in accordance with these Terms. You agree not to:

• Use the Service in any way that violates any applicable federal, state, local, or international law or regulation.

• Use automated scripts, bots, scrapers, or similar tools to access the Service, except for legitimate search engine crawlers.
• Interfere with or disrupt the Service or servers or networks connected to the Service.
• Reproduce, duplicate, copy, sell, resell, or exploit any portion of the Service for commercial purposes without our express written permission.
• Misrepresent Alertra data as official government warnings or emergency alerts.
• Use the Service to generate false, misleading, or alarmist reports about seismic activity.

We are not affiliated with, endorsed by, or officially connected to any of these agencies. Their data is used in accordance with their respective public use policies. The accuracy and availability of third-party data is beyond our control.
