Not a social product
FC21 is organizational security infrastructure — no feed, no ads, no matching.
About FC21
Foundational Communication
FC21 started from a simple observation: privacy in communication products rarely disappears all at once — it goes permission by permission, metadata field by metadata field.
The frog — framed carefully
The familiar boiling-frog thought experiment fits the FC21 narrative: people do not notice when contacts, location, metadata, and identity drain away piece by piece — until the habit feels normal.
FC21 does not use that story as shock marketing. It is an honest contrast: You shouldn't have to get used to it.
The 7-screen story (mobile onboarding)
Same pacing as the iOS app (`FC21AuthLandingCopy`). These are the English lines the app shows.
1
Hey.
2
But most conversations don't.
3
Privacy rarely disappears all at once.
4
You got used to it.
5
FC21
6
Infrastructure need not know.
7
This is your communication space.
Values
Honest language
We do not claim what we cannot prove. Platform knowledge is documented, not denied.
Sovereign deployment
Every major feature must be operable in sovereign deployment mode — for critical operations.
Crypto-agile
Architecture with a post-quantum design path — no quantum-proof marketing without a review.
Rebrand history
The project was formerly Aegis and was renamed FC21 after Crypto Design Review Candidate 0.1 was frozen. Historical Aegis artifacts remain for traceability. No external cryptographic review has been performed yet.
