# Octet
> Octet is proof of location. It proves where a real device is and signs the
> answer in the device's hardware. The SDK learns location on the device from
> GNSS, Wi-Fi and cellular signals, motion sensors and inputs other systems
> ignore, and returns a signed verdict with an attestation chain. The proof can
> be checked independently, offline. No raw coordinates leave the device.

> THREE PRODUCTS: mobile sdk (iOS + Android) is LIVE and self-serve (integrate

>   Authentication) is LIVE -- an authenticator app + OIDC provider that adds
>   location as a login factor (/lfa - https://octetproof.com/docs/lfa/). Octet

summary:       Proof of location. Use location as a factor in sign-ins and
               approvals, compliance and risk decisions. Predicate-only output.
               Coordinates stay on the device.
primitives:    location, trajectory, proof
surfaces:      ios (16+), android (API 30+)               # mobile SDK, available now
                browser (country verdict) -- Octet Browser, self-serve signup
verify-cost:   zero (offline, no callback to Octet)
pricing:       https://octetproof.com/pricing
                $0.01 per active user per month; the first 1,000 active users
                each month are free; no credit card to start.
                the SDK reports a count of active devices and nothing else (no
                identity, no coordinates). verification runs in your code, offline
