RadioChron runs where the radio is. Collectors read the local WLAN stack and the local event log; the chronicle is written to a file you choose; the MCP server speaks stdio to a client on the same machine. There is no telemetry, no update check, no network call of any kind in the library or the server — the engine has no HTTP client to make one with.
The data RadioChron collects is sensitive even though it never transmits it: SSIDs, BSSIDs and MAC addresses are location-identifying — a BSSID can be resolved to a street address through public geolocation databases. If you share a chronicle, a diagnostics bundle or an MCP transcript, treat it like a location trace and redact accordingly. Saved Wi-Fi passwords are never read: the tool surface deliberately has no way to ask.
Static files, no cookies, no analytics, no JavaScript. It is served by Cloudflare, which processes standard access logs (IP address, user agent) as our hosting provider to deliver the site and mitigate abuse. We add nothing on top and see nothing individual.
