Privacy-first design
Local Wi-Fi transfer and privacy
Core SmenaFon principle: customer files never pass through smenafon.ru. The site handles licenses, dashboard and aggregated stats; payloads move only inside the local network.
What stays local
Files, contacts and media go to a local IP like 192.168.x.x. QR URLs are not public internet addresses; the server listens only inside Wi-Fi.
What the SaaS sees
Licenses, agent heartbeats and aggregated session counters: photo/video/file counts, duration and billing. Filenames and contents are not uploaded.
Model limits
The network must be trusted: disable guest AP isolation, avoid untrusted public Wi-Fi and end the session after verifying receipt on the new phone.
