Privacy architecture
A plain-language map of what FC1 processes to run Marketplace, shipping, and Network — and what E2EE is designed to keep off our message servers.
Operational dataE2EE message bodiesLegal policies
What FC1 necessarily processes
Commerce & shipping
Orders, addresses, rates, labels, and tracking metadata required to move packages and settle payments.
Network ciphertext
E2EE message payloads are stored so devices can sync — servers are not designed to read those bodies.
Payments
Card data is handled by Stripe (PCI DSS). FC1 does not need raw PANs for normal checkout.
Account profile
Identity, sessions, and account security controls live outside the E2EE message envelope.
Authoritative legal documents
This page explains architecture. Binding terms live in the Privacy Policy and Terms.
