Privacy Policy
Last updated 28 August 2026
There are no accounts, no logins and no advertising here. Nothing about you is sold or shared. This page covers the small amount of data that is involved anyway.
What is stored on your device
Your settings are kept in your browser so the site opens the way you left it. That includes the theme, units, map detail and playback speed. Radar scans you have viewed are also kept for a while, so moving back and forth along the timeline does not download the same scan twice.
All of this stays on your device and is never sent anywhere. Clearing site data for this domain removes it. None of it uses cookies.
Analytics
The site uses Numative to count page views and see which pages get used. It does not use cookies, does not build a profile of you and does not follow you to other sites. What it records is general: the page, where you came from, roughly which country, and what kind of device.
Location
Two features can ask your browser for your location: centring the map on you, and sorting the radar list by distance. Your browser asks permission first. The answer is used in the page and nowhere else. It is never sent to this site or stored. If you say no, you only lose the sorting.
Server logs
The site is served through Cloudflare, which handles IP addresses and request details in order to deliver pages and block abuse. That is normal for any website and is described in Cloudflare's privacy policy. Our own logs record which pages were requested and which errors happened, not who requested them.
Data from other organisations
Radar, warnings, satellite and forecast data come from NOAA, the National Weather Service, NASA and the Iowa Environmental Mesonet. Maps come from OpenStreetMap. Your browser requests some of these directly, which means those organisations see your IP address, exactly as if you had visited them yourself. Their own policies cover that.
Children
The site is not aimed at children and collects no personal information from anyone, including children.
Your rights
There are no accounts and no personal information is collected, so there is nothing held here to request, correct or delete. Anything the site put on your device can be removed by clearing site data in your browser. If you believe you have a right over data held about you, write to us and we will answer.
Changes
If this policy changes in any real way, the date at the top of this page changes with it.
