About Keryx Maps
Built for preparedness, not dependency.
Keryx Maps brings hazard information, offline maps, trip planning and privacy-conscious navigation together in one application — so you can understand what is happening and prepare for it, including when the network is not there.
Why Keryx exists
Information that matters in an emergency is scattered. Earthquakes, fires, storms, air quality and space weather are each published by different agencies, in different formats, on different sites.
Most mapping tools assume a steady connection, which is exactly what can disappear when conditions turn bad. Getting from “what is happening” to “where do I go” often means juggling several unrelated apps.
And people planning for the worst do not always want their movements recorded on someone else's server. Keryx was built to put these pieces in one place, working offline where it can, without tracking where you go.
How we approach it
Authoritative data first
Hazard information comes from the agencies and networks that issue it, and each event names its source.
Geographic context
Events are shown on the map, and alerts are matched to the map regions you download, so you see what affects the places you care about.
Prepare while it is calm
Download maps, save pins and plan routes and trips ahead of time, so they are on your device when you need them.
Work done on your device
In the installed apps, maps are stored locally and routes are calculated on the device, without a connection.
Privacy by architecture
Our servers do not receive your GPS coordinates. Sync is end-to-end encrypted, so we store data we cannot read.
Established vs. experimental
Source data is presented as issued. Exploratory analysis stays in Labs and is labelled experimental.
Behind Keryx Maps
Keryx Maps is built by RDF Industries, Inc., an independent company with a science background. Being small keeps us focused: one product, built around a clear set of priorities — accurate sources, offline preparation and privacy.
We do not run a seismology lab or a weather model. We bring together what the authoritative sources publish, present it clearly, and stay out of the way.
Authoritative sources
Keryx does not issue hazard warnings. We bring together 45+ data feeds from 25+ sources — government agencies, scientific organisations and monitoring networks — and show each event with the agency it came from, so you can check it at the source. For official emergency instructions, always follow your local authorities.

Labs: experimental work
Labs is where we explore questions such as whether patterns in solar activity line up with other hazards. None of it is presented as accepted science: everything in Labs is marked experimental, and it does not generate alerts. The authoritative sources stay primary.
At a glance
- Offline maps and on-device routing in the installed apps
- End-to-end encrypted sync of your pins, routes and trips
- Apps for Android, iOS, Windows, macOS, Linux, plus the web app
- 99% uptime, including brief restarts when we ship updates
- Automated monitoring of the service around the clock
How we use AI tools
We use frontier language models as working tools — for code review, summarising source papers and exploring patterns. They are not a stand-in for the agencies that issue hazard data or for primary scientific evidence, which remain the authority.
