When the rain falls hard, trust AquaGuard.

No. AquaGuard works in any modern browser at aquaguard.vn — open the page, sign in and you can send an SOS, read the live flood map and check on your family straight away. If you prefer something that lives on your phone, there is also a native iOS app. The web and iOS versions connect to the same live rescue network, so a request sent from one appears instantly for rescue teams and for family members on the other.

Sending an SOS needs a data connection, and in a flood that is often the first thing to fail, so we built a few safety nets around it. AquaGuard includes one-tap registration for emergency 4G data packages from Viettel, Vinaphone and Mobifone, so you can get back online quickly. Direct-dial shortcuts for Police (113), Fire (114) and Ambulance (115) work with an ordinary phone call, and our flood safety guides can be read even when the connection drops. We recommend setting up your account and trying the app before the flood season, not during it.

Yes. AquaGuard is free for residents — creating an account, sending an SOS, following your rescue on the map, using the safety guides and connecting with family members all cost nothing. Our goal is that no one hesitates to ask for help because of a price tag. Organizations that want dedicated onboarding, dashboards or integrations can talk to us about a partnership.

Rescuers register at aquaguard.vn and choose the Rescuer role. Because this role gives access to everyone’s requests, it is protected by a team access code, which we share with organizations and volunteer groups we work with — use “Partner With Us” below to ask for one. Once inside, you can form or join a rescue team, switch your duty status on when you are available, and receive requests ranked by distance and urgency. Every request is visible to the whole rescue network, so teams can see what has already been accepted and avoid duplicating each other’s work.

Your location is used only for rescue: to attach an exact position to your SOS, to guide the nearest available rescuer to you, and to let you watch them approach on a live map. If — and only if — you connect with family members, they can see your safety status and last known position. Access is limited by role, so residents, rescuers and admins each see only what their job requires, and every request needs a signed-in account. Live positions are used for real-time tracking and are not kept as a continuous location history; only the start and end points of a rescue-tracking session are recorded.
