Version 1.5 · Last updated 2026-09-04 · legal@prestancelab.com

This Data Processing Agreement (this "DPA") governs Prestance Lab's processing of Personal Data carried out in the course of providing the Services under the Agreement. Capitalised terms not defined here have the meaning given to them in the General Terms and Conditions or, failing that, in the GDPR. It is incorporated by reference into the Agreement pursuant to GTC §14.3.

1. Roles and definitions

In order to provide the Services, Prestance Lab is required to process the Personal Data of Authorized Users and of the Customer's clients whose data Authorized Users record in client files or that the Customer shares from its own systems. The Parties acknowledge that, with respect to the processing of such Personal Data carried out under the Agreement, the Customer acts as the data controller (the "Controller") and Prestance Lab acts as the data processor (the "Processor").

"Controller", "Data Subject", "Personal Data", "Process / Processing", "Processor", "Sub-processor", "Data Protection Impact Assessment", "Data Protection Officer" and "Personal Data Breach" have the same meaning as in the GDPR.

2. Applicable legislation

Each Party undertakes to comply with the provisions of any applicable legislation concerning the protection of Personal Data, in particular the French Data Protection Act No. 78-17 of 6 January 1978 in its latest version in force and Regulation (EU) 2016/679 of the European Parliament and of the Council of 27 April 2016 on the protection of individuals with regard to the processing of personal data and on the free movement of such data (the "GDPR"), together the "Applicable Data Protection Legislation".

3. Description of the processing

The Personal Data processing operations carried out by the Processor are described below.

Concerned service(s)
The Services as defined in the GTCs (Solution, Maintenance Services, and Professional Services where applicable).
Nature of the processing operations
Storage, consultation, organization, structuring, transmission, erasure, recording (voice — the advisor's calls with the assistant and practice sessions only), transcription (speech-to-text), automated text generation (client briefs, debrief summaries, message drafts), automated analysis (coaching feedback in practice sessions; pattern extraction across debriefs), profiling within the meaning of Article 4(4) GDPR limited to (a) an advisor's own practice-score progression over time, visible to that advisor only, and (b) activity counts and conversation patterns per team and per advisor for the Customer's management, and aggregation and anonymization.
Purpose(s) of processing
Performance of the Agreement and provision of the Services, including: enrolment and authentication of Authorized Users; delivery of the assistant over the channels activated in the Order Form (telephone, WhatsApp, SMS, email, and the optional mobile application); maintenance of the client files an advisor builds through their own debriefs, and of the briefs prepared from them; drafting of follow-up and outreach messages that the advisor sends from their own tools; practice sessions in which the Solution plays a client and gives the advisor private coaching feedback; aggregated team signals for the Customer's management; technical support; and security monitoring.
Categories of Data Subjects
(a) Authorized Users of the Customer (typically the Customer's employees acting in a sales-advisor, manager, or administrator role); and (b) clients of the Customer whose Personal Data an Authorized User records in a client file, or that the Customer shares from its CRM.
Categories of Personal Data — Authorized Users
Identity data (first name, last name); professional contact data (professional email address, professional mobile number); authentication metadata (hashed password, MFA token state, session identifiers, enrolled channel identifiers); advisor exchanges with the assistant (call audio and transcripts; WhatsApp, SMS and email message content); practice sessions (voice recordings of simulated client conversations, advisor → persona transcripts, coaching feedback, performance scores — visible to the advisor only); manager signals (activity counts and conversation patterns per team and per advisor); technical telemetry (IP address, device and browser user-agent, connection quality, crash and error logs, pseudonymous usage events). Account administration, authentication and security logs, billing records, and aggregated product analytics that Prestance Lab holds as controller are described in the Privacy Policy (GTC §6.2); they are listed here only where the same records also serve the Customer's processing.
Categories of Personal Data — clients of the Customer
The content of client files as recorded by the advisor: name or initials, contact preferences, purchase and visit history, stated preferences and sizes, occasions and dates, and free-text notes. Where the Customer agrees in the Order Form, a bounded set of data read from the Customer's systems: product and stock information, calendars, and CRM data. Access to Customer systems is read-only; the Customer's CRM remains the master record.
Special categories of Personal Data
None processed by design. Authorized Users are instructed not to record special-category data about clients (Acceptable Use Policy §3). The Solution does not perform emotion recognition in the workplace within the meaning of Article 5(1)(f) of the EU AI Act, and it never records, listens to, or contacts the Customer's clients.
Duration of the processing
Until deletion by the Authorized User or by the Customer administrator, and at the latest at the end of the Agreement followed by the deletion procedure described in Section 5 below and in the Security Policy (typically within 30 days; backups purged within 90 days).

5. Processor's undertakings
