How we protect your data

End-to-end encryption for over-the-wire transmissions

AES 256-bit encryption for all data transfers between the bridge and sensors (that's the same level of security as a bank vault)

OAuth 2.0 for client authentication (the same level of authentication that Facebook and Twitter use)

Third party security and penetration testing
