A private recovery companion — with an optional consent-based wearable — designed to avoid facial recognition and biometric surveillance. The wearable is not intended for continuous tracking; production controls require testing and validation.
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.
Proposed local Bluetooth Low Energy proximity triggers are designed to avoid broad cloud-storage tracking; the architecture and safeguards require pilot validation.
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.

Honesty builds trust. Here is exactly where BannedBands and Sentra sit.
Formal self-exclusion is managed by official providers and venue processes. We help people live with the choice they have made.
Development position — not an endorsement, compliance claim, or implemented governance model. We are treating Māori data sovereignty as a design and governance requirement for any future pilot that may involve Māori data, whānau, hapū, iwi, or collective interests.
Before a pilot involving Māori data, we propose working with Māori partners to define authority, tikanga, access rules, accountability, and benefit-sharing. We will not represent this page as Māori endorsement or as governance already in place.
Participants and governance partners should be able to see where information is held, who can access it, what retention period applies, and how deletion or withdrawal works. Proposed controls include role-based access, access logs, documented retention schedules, and auditable deletion requests.
This public website does not implement Māori governance. The interactive demo uses illustrative data in the browser and is not a pilot, register, or production service. It does not send entered demo information to a server. See the demo status notice and the fuller sovereignty commitments.
Whether and how Māori data is collected, classified, hosted, accessed, retained, deleted, shared, or used for research remains subject to qualified Māori-led co-design and governance. These commitments are a starting point for that conversation, not a substitute for it.
Initiating collaborative validation trials with regulatory groups, certified NGOs, and premium commercial venues across New Zealand and Australia. Full enrolment and identity verification is handled through authorised support services — not through this public form.
