Version 1.3 · Last updated 2026-09-04 · legal@clauzy.ai

This page is the technical reference for the Prestance Lab Solution. It describes the device, browser, network, audio, and account prerequisites that Customers and Authorized Users must meet to use the Service. It exists to give procurement, IT, and end users a single canonical surface to consult before, during, and after deployment.

1. Overview

The Solution is a voice-first rehearsal and coaching platform for retail teams, delivered as a web application for sales advisors, managers and HR. Real-time voice drills run over WebRTC and require low-latency network conditions and a working microphone on the end-user device.

2. Supported devices

Mobile

• iOS 16+ — iPhone 11 or later recommended.
• Android 12+ with at least 4 GB RAM.

Desktop

• Any device capable of running one of the supported browsers listed below.

Notes

• iPad is supported via the iPhone application running in compatibility mode.
• Chromebook is supported via Chrome on Chrome OS 110+.

3. Supported browsers

The web dashboard and the manager surfaces are supported on the following browsers:

4. Network requirements

Pursuant to Section 2.3 of the General Terms and Conditions, Customer is responsible for ensuring that its hardware, software, network connectivity, and systems are adequate to benefit from the Service. The following are the minimum network conditions for a usable voice-drill experience:

• Sustained throughput of at least 1 Mbps upstream and downstream per concurrent drill session.
• Round-trip latency to the nearest EU edge no greater than 150 ms for natural voice cadence.
• WebRTC over UDP preferred, with TCP fallback; firewall configuration should follow the LiveKit firewall guide.
• WebSocket support; no aggressive corporate proxy that breaks wss:// connections.
• No content-filter or inspection device that strips audio MIME types.

5. Audio hardware

• Built-in laptop or phone microphone is acceptable.
• For boutique-floor acoustic conditions, AirPods Pro or any wired USB-C / Lightning headset with noise isolation is recommended.
• Bluetooth Classic headsets using HFP work but degrade speech intelligibility; AAC or aptX codecs are preferred.

6. Account provisioning

• Authentication is via email and password, brokered by Supabase Auth with ES256 JWTs. Multi-factor authentication is supported where the Customer's identity provider offers it.
• Named seats only — shared logins are prohibited per Section 5.3 of the General Terms and Conditions.
• The Customer Administrator provisions Authorized Users through the manager dashboard. Bulk CSV upload is available on request.
• Password requirements: minimum 12 characters; rotation every 12 months recommended.

7. Languages

• Interface (mobile application and web dashboard): English.
• Voice persona: English, with French loan-words for luxury vocabulary. This is intentional and supports the luxury-retail register the Solution is designed to rehearse.
• A French interface translation is planned for a later release and is not blocking for v1.

8. Browser-side permissions

9. What if a prerequisite is not met?

If a device, browser, network, or audio prerequisite is not met, the Solution surfaces a clear preflight check inside the application and refuses to start a drill rather than degrade voice quality silently. This is by design: a degraded drill teaches the wrong reflexes and is worse than no drill at all.

If the preflight check blocks a session and the cause is not obvious, contact support@clauzy.ai.
