How Signal handles your data, where it's stored, and what certifications back their claims.
US (non-profit) (HQ: Mountain View, California, US) / Signal Technology Foundation
Signal stores almost nothing about you. Your phone number is the only personal data on their servers, and even that is not linked to your identity. Messages stay on your device, not in the cloud. Signal has a dedicated data protection officer you can contact at privacy@signal.org.
