Welcome to the official website of Massimo (MAX) Russo, creator of the MAX App ecosystem, where mathematics becomes the key to a new kind of digital security: autonomous, post-quantum, and fully private.
MAX App builds a mathematical identity starting from two secret phrases that always remain on your device. No mandatory email, no phone number, no profile to store: the server only sees public keys, digital signatures, and encrypted packets, never your phrases or your private keys.
iOS only — requires an Apple ID and the free TestFlight app.
Your identity is not an email address: it is a set of cryptographic keys deterministically derived from your phrases, only on your device. Each module (Login, Chat, Lock, Signature) uses different keys, so any potential compromise remains confined to that single module.
No personal data is required to use the app. Zero phone numbers, zero profiles, zero tracking. The server only sees public keys, SPHINCS+ signatures, and encrypted packets (FrodoKEM + MX²), without ever knowing your phrases or your private key.
SPHINCS+ for signatures, FrodoKEM for key exchange, and MX² for local symmetric encryption. Protocols designed for the post-quantum era and verifiable from the outside as well, by exporting packets that can be checked with independent tools.
