Privacy by architecture
The brain that cannot read your home.
Most smart-home companies see everything. Every Lutron press, every Sonos
play, every motion sensor trip, every door unlock, every word your voice
assistant heard. We don't, and we've engineered the system so we
can't — even if our servers are seized.
Your credentials and home state are encrypted with a per-household key derived
from Sign in with Apple plus a passkey held in your iPhone's Secure Enclave.
The HearthPilot Brain runs inside AWS Nitro confidential-compute enclaves
that publish their binary hashes to a public transparency log; your device
verifies what's running before it releases ciphertext. We don't have the
keys. Our employees don't have the keys. A subpoena to us produces ciphertext.
This is the same architectural pattern Apple ships as Private Compute Cloud
for Apple Intelligence. We implement it on AWS so we control the full stack.
