A private recovery companion — with an optional consent-based wearable — that helps people sustain the self-exclusion choices they make. No facial recognition. No biometric surveillance. No continuous tracking.
Tamper-resistant physical endpoints working in harmony with localized perimeter proximity tracking.
A sealed, tamper-evident band worn by choice — an optional physical cue to help hold the line you set for yourself.
Zero-surveillance Bluetooth Low Energy proximity triggers communicate locally with venue configurations — without broad cloud storage tracking.
A low-energy architecture with a weekly 30-second integrity check, powered by a sealed long-life battery lasting approximately nine months — no charging required.
Tamper-evident design flags interference attempts. The band is a personal support tool, not a legal exclusion record.
All items supported by contemporaneous documentation available on request. None of this constitutes a confirmed procurement or endorsement.
Hardware status: V1 flexible-PCB production run exists (Aug 2018). Bench demonstration hardware is in preparation with the original electronics engineer. A photograph of the 2018 PCB will be added here once cleared for public use. Until then, concept imagery on this site is illustrative.
One system, three aligned outcomes — for the bodies that regulate, the venues that comply, and the people in recovery.
The wearable works best alongside supportive tools. The Sentra companion app turns each person's own goals into positive, visible progress.
