Security & confidentiality

How we handle your data during a mission.

A concrete explanation of our confidentiality and data-handling practices, to answer the questions you have before trusting us with sensitive data.

Our confidentiality commitment

Every Diamnova engagement starts with a clear confidentiality commitment — verbal from the first conversation, formalized in writing before any access to your data. This commitment applies to Diamnova and to any associate consultant mobilized on your engagement.

In practice: only the people actually working on your engagement have access to your data — never a broader team by default.

The principles we apply

01

Minimization

On ne demande que les données nécessaires au périmètre cadré avec vous — jamais un accès plus large "au cas où".

02

Restricted access

Only the team assigned to your engagement has access to the data — documented in every proposal before starting.

03

Limited retention

Data shared with us is kept only for the duration of the engagement, then deleted or returned per your instructions.

04

No reuse

Your data is never reused for another engagement, nor shared with another client, in any form.

GDPR and personal data

If your engagement involves personal data of EU residents, Diamnova acts as a data processor under GDPR (General Data Protection Regulation). We are ready to sign a Data Processing Agreement with you, specifying the commitments applicable to your specific case — purpose of processing, retention period, security measures, and your rights of control.

A specific question before trusting us with your data?

Where will your data be hosted during the engagement, who exactly will have access, how will it be deleted at the end — these are legitimate questions, and we'd rather answer them precisely on a case-by-case basis, tailored to your context, than with a generic formula on this page.

A specific question before starting?

Let's discuss it directly, before any engagement — no generic answer on a topic that deserves precision.
