RadiusAwareness without alarmism.
Radius reserves interruptions for higher-priority nearby activity and keeps ordinary map browsing quieter.
Independent · Texas-built
A calmer way to understand what is happening nearby.
Radius exists because local public-safety information is often scattered across raw active-call tables, radio traffic, and isolated public reports. The goal is simple: make available activity easier to understand without making it more alarming—or more certain—than the source supports.
Every product decision should help people understand nearby activity without overstating what the source can prove.
Plain language with source context.
Reports explain what was reported, where it was reported, and how precise the location appears to be.
Uncertainty stays visible.
Radius says when a location is approximate and does not claim to show every incident or verify every detail.

Editorial principles
The map should never pretend to know more than it does.
Radius uses cautious wording, removes sensitive details, limits false precision, and keeps source information attached. Corrections are part of maintaining the product, not an exception to it.
- Use “reported” language when facts are not independently confirmed.
- Do not identify suspects, victims, or private medical details.
- Do not publish tactical or low-confidence information for novelty.
- Correct, reduce precision, or remove reports when warranted.
