Privacy Policy

Last updated November 13, 2026 · Applies to the iSurvive app (Google Play: “iSurvive: Disaster Prep”; App Store: “iSurvive with Marichu”) and to this website.

Who we are

iSurvive is made by DBL Nexus. DBL Nexus is the trading name of the individual developer shown as the seller in the app store. Contact: support@dblnexus.com.

What the app stores on your device

Your learning progress, quiz answers and review statistics, missions, drill results, household plan (people, meeting places, an out-of-area contact and any notes you choose to type), kit list, optional “How ready do you feel?” check-ins, certificates, the optional name you add to certificates, your settings, and the age group you choose when you first open the app (Under 13, 13 to 17, or 18 and over). We never ask for your birthday. The age group is used only on your device to show suitable lessons. All of this is kept in the app’s private storage on your device. We cannot see it, and on Android it is excluded from cloud backups and device transfers.

Chat with Marichu

The chat runs entirely on your device, with or without internet. A small on-device search model finds the matching lesson in the app; it does not generate answers. Your messages are not sent anywhere and are not saved after you leave the chat.

Location (optional)

The app asks for location permission only when you tap “Check with my location” or “Add my coordinates”. It uses your location on your device to choose your country’s emergency hotlines, or to add your coordinates to a help message that you then decide to send. Your location is not stored and is never sent anywhere by the app. You can refuse or revoke the permission at any time and choose your country from the list instead.

Notifications (optional)

If you turn on reminders, the app schedules local notifications on your device. Nothing is sent to us or to a notification service. You can turn them off in Profile or in your phone’s settings.

Things you choose to share

When you tap Share (a certificate, your household plan image, a help message with your location) or send a problem report, your phone’s share sheet or email app opens and you choose the app and the people. What you send is then handled by that app and its privacy policy. Nothing is shared automatically.

Links and calls

Source links and videos open in your browser or video app, and call buttons open your phone’s dialer. Those apps and websites have their own privacy policies.

Ads

iSurvive is free and supported by ads from Google AdMob. You may sometimes see a full-screen ad after you finish a lesson, and you can choose to watch an optional short video for bonus XP.

• Adults (18 and over) choose personalized or non-personalized ads.
• Ages 13 to 17 see non-personalized ads only.
• Under 13 sees no ads.
• Ads never appear on SOS, Panic mode, hotlines, crisis lines or the emergency chat.
• You can change your choice anytime in Profile > Ad choices.

Google AdMob is a third-party service provided by Google. To show ads, and to measure them and prevent fraud, it may collect information from your device, such as your advertising ID, IP address and information about the ads you see and tap. Google handles this information under its own privacy policy: policies.google.com/privacy. Apart from Google AdMob, the app includes no analytics, crash-reporting or other software that collects data. If this changes, we will update this policy and the app store privacy disclosures before the change is released.

Deleting your data

Open Profile and tap “Delete all my data” to erase everything iSurvive stored on your device. Uninstalling the app also erases it. We hold no copy.

This website and the waitlist

If you join the iSurvive waitlist on this website, we collect your email address and your consent through Cloudflare. Cloudflare hosts this website and stores form submissions for us. We use your email only to tell you when iSurvive launches; see also our website privacy notice. To be removed, reply to any of our emails or write to support@dblnexus.com. Like any web host, Cloudflare processes technical data such as IP addresses to deliver and secure the website. If you email us for support, we use your message only to reply to you.

Children and use in schools

iSurvive is intended for users aged 13 and over. If someone chooses “Under 13” when the app first opens, the app shows only emergency numbers and Panic guides. Because the app has no account and sends no personal data to DBL Nexus, we do not collect information from children or students. Anyone who chooses “Under 13” sees no ads, and ages 13 to 17 see non-personalized ads only. Schools, LGUs and other organizations that use iSurvive with students should obtain any consent required by their own policies and local law.

Security

Because your data stays on your device, it is protected by your device’s own security. Use a screen lock to keep it private.

Your rights

Under the Philippine Data Privacy Act of 2012 (Republic Act No. 10173) you have the right to be informed, to access, to object, to correct, to erase or block, to data portability, and to claim damages. Because the app keeps your data only on your device, you can view, change or erase it yourself at any time. For waitlist or support emails you send us, write to support@dblnexus.com. You can also complain to the National Privacy Commission of the Philippines (privacy.gov.ph) or to the data protection authority where you live.

Changes

If this policy changes, we will post the new version here with a new date.
