Keryx Maps

About this app

Keryx Maps is a privacy-first mapping and disaster preparedness app built for when connectivity matters most — and when it's gone entirely.

Download detailed maps for fully offline use, including street-level detail, topographic overlays, and turn-by-turn routing that works without cell service. Monitor real-time hazards from earthquakes and wildfires to severe weather and space weather events — all on one dashboard.

YOUR LOCATION STAYS ON YOUR DEVICE
Unlike other mapping apps, Keryx Maps never sends your GPS coordinates to our servers. Your position is processed entirely on-device. You cannot compel data that was never created — we provide privacy by architecture.

BUILT FOR EMERGENCIES
When disasters knock out cell towers and internet, most mapping apps become useless. Keryx Maps is designed to work when infrastructure fails — your maps, routes, and saved locations are stored locally and always accessible.

Data collected: email and name for your account, phone number only if you opt in to SMS alerts. Your GPS location never leaves your device.

What’s new

A major update to how Keryx keeps you informed. You now get global alerts for severe earthquakes, hurricanes, volcanoes, tsunamis, and radiation events anywhere in the world, plus civil unrest events on the map. Family sharing brings end-to-end encrypted pin sync across devices. The Pins page is unified with categories, and trip planning includes fully offline navigation with turn-by-turn directions.
