Terms of Use
Last updated November 2, 2026 · Applies to the iSurvive app and this website.
Safety disclaimer
iSurvive is an educational app. Its content is adapted from official sources, but it is not a substitute for emergency services, official warnings or professional advice.
In an emergency, always call your local emergency number first and follow the instructions of emergency services and local authorities.
1. About iSurvive
iSurvive is a survival and emergency preparedness app made by DBL Nexus. DBL Nexus is the trading name of the individual developer shown as the seller in the app store. By using the app or this website, you agree to these Terms.
2. Educational content
Lessons, cards, quizzes, Panic mode guides and chat answers are general information based on official sources such as the Red Cross, Ready.gov (FEMA), the US National Weather Service, CDC, GOV.UK, PAGASA, PHIVOLCS and WHO. iSurvive is independent, is not a government app, and is not affiliated with or endorsed by these organizations. Situations differ, and guidance from official sources can change. Always follow current instructions from emergency services and local authorities.
3. Chat with Marichu
The chat runs offline. It finds answers in the app’s lessons and does not generate new content. It does not cover health or medical questions. Do not rely on it in place of emergency services.
4. Emergency hotlines
Hotline numbers are checked against official directories, but numbers and services can change and may not be available everywhere. Calling requires a working phone network. If a number does not connect, try your country’s general emergency number or ask someone nearby to call.
5. Certificates
Certificates show that you completed a topic in the app. They are for personal motivation and are not a professional qualification or a substitute for formal safety training.
6. Free
iSurvive is free to use and has no in-app purchases. It is supported by ads from Google AdMob, which never appear on SOS, Panic mode, hotlines, crisis lines or emergency chat. See our privacy notice for how ads use data.
7. Acceptable use
Do not misuse the app, attempt to disrupt it, or use share cards to mislead or harm others.
8. Intellectual property
The app, its design, the iSurvive name and Marichu are owned by DBL Nexus. Content credited to official sources remains subject to those sources’ terms.
9. Limitation of liability
To the extent permitted by law, iSurvive is provided “as is”, and DBL Nexus is not liable for loss or harm arising from reliance on its content instead of emergency services or professional advice. Nothing in these Terms limits rights you have under consumer law that cannot be excluded.
10. Changes
We may update these Terms. The new version will be posted here with a new date.
11. Governing law and contact
These Terms are governed by the laws of the Republic of the Philippines. If you are a consumer, you also keep the protection of the mandatory laws of the country where you live. Contact: support@dblnexus.com.
