A privacy-first explanation of why Secreto Hub keeps transfers on the local network instead of using cloud servers.

SecretoTools is developed as a practical software project, with decisions tested against real television devices and real user needs. This article documents the principles behind that work.
Keep the transfer close to the user
Secreto Hub receives files directly over the local network. The file moves between the sender and the TV without first being uploaded to an external cloud service.
Reduce friction
The sender only needs a browser. A local address and QR code make the television discoverable without requiring a second mobile application or account.
Make privacy part of the architecture
Local transfer is not a marketing layer added later. It is the product model: no remote storage, no account system and no unnecessary collection of transfer data.
Secreto Hub 1.0 adds Secure Encrypted Transfer to the local-first design. Files and transfer metadata are encrypted in the sender browser before transmission, the active receiver uses session-specific pairing and authenticated requests, and Secreto Hub decrypts completed data locally on the television. The initial browser page is still served over the local network, so this is not described as HTTPS or end-to-end encryption.
