1. Your devices find each other
On the same Wi-Fi, the GleamShare apps for Windows and Android announce themselves and list every other device they hear. In the browser, devices on the same network see each other through a small signaling server that only passes the handshake.
2. You pick what to send
Files, whole folders, or just a link or a note. Tap a device and the other side gets an Accept or Decline prompt. Nothing is saved until they accept.
3. It goes straight across
The file travels device to device and is checked with a SHA-256 fingerprint when it arrives. A damaged file is thrown away instead of saved. In the browser the connection uses WebRTC, which is always encrypted.
When the other person is not online
Choose Send by email or link. Your browser locks the files with a random key first, uploads only the scrambled data, and the key stays in the link after the # (browsers never send that part to a server). The link works for 7 days, then the data is deleted.
What is protected today
- Browser transfers: encrypted (WebRTC) and verified.
- Email and link shares: end-to-end encrypted in your browser. The server cannot read them.
- Windows and Android apps on your Wi-Fi: verified with SHA-256, with an Accept prompt. Encryption on the local network is on our roadmap, so use trusted Wi-Fi for now.
