If you make a Rayhunter, think twice before enabling its smartphone notification feature. The documentation doesn't directly warn, but presumably the notifications leak the fact that you use Rayhunter, and they go through centralized services. (With notifications being practically easier for some parties to check centrally, than how the device appears to the various cellular network towers.)
As situations sometimes become complicated in a locale, I suppose that this leaking could get you flagged as a potential troublemaker, or included in a small pool of persons of interest regarding an event/incident, etc.
(Most people neither think about nor are concerned with such possibilities, but if you find this device fun or interesting, then I'd guess probably you are more likely than the average person to want to reconcile how it works, with your fun/interesting/real threat model.)
Per <https://efforg.github.io/rayhunter/configuration.html>:
> ntfy URL for Sending Notifications, which allows setting a ntfy URL to which notifications of new detections will be sent. The topic should be unique to your device, e.g., https://ntfy.sh/rayhunter_notifications_ba9di7ie or https://myserver.example.com/rayhunter_notifications_ba9di7i.... The ntfy Android and iOS apps can then be used to receive notifications. More information can be found in the ntfy docs.
