I am testing roadstrapp (nprofile…afgy) (it's not a trap on the road) and have a question, if I publish a speed limit radar, does it get published to osm or remains in the app network stored on nostr relays? The other alerts like police remain on nostr relays? Where are the data stored? I would like to suggest reporting police stations too.
