Personal data

Privacy policy

Last updated: August 26, 2026

1. Data controller

The data controller is Insight Group, a limited liability company operating under the commercial name Mellion, SIREN 106 691 108. Its legal contact details are provided in the legal notice. The company determines the purposes and means of the processing activities described on this page. For any questions or requests related to your data : oscardessein@mellion.fr.

2. Personal data processed

The contact form allows you to transmit your identity, professional contact details, organisation, nature of your enquiry, and a note specifying your request. You can also choose to contact Mellion by email or use external booking links and LinkedIn. Depending on how you contact us, the data processed may also include information necessary for a call and the correspondence history.

Netlify’s hosting can also process technical connection data, such as IP address, timestamp, requested resource, browser type, and security logs, to provide and protect the service.

3. Purposes and Legal Bases

Respond to an inquiry and prepare a proposal
Pre-contractual measures taken at your request.
Manage client relationships and deliver services
Performance of a contract and compliance with legal obligations.
Ensure the security and continuity of the site
Legitimate interest to protect the service and its users.
Maintain appropriate professional follow-up
Legitimate interests, subject to your right to object.

4. Retention periods

Interactions with prospects are retained for a maximum of three years from the date of collection or the last prospect-initiated contact, unless you object or due to specific legal requirements. When a contractual relationship is established, relevant data are retained during the relationship and then archived for the durations required or permitted by accounting and tax obligations, and the defence of rights. Technical logs are retained for a limited duration determined by their security purpose and the hosting configuration.

5. Recipients

The data is accessible to Oscar Dessein and authorised individuals for the commercial activity known as Mellion. Form submissions are processed and stored by Netlify to transmit and filter unwanted submissions. Only when necessary, they may also be transmitted to the technical specialists involved and providers that supply communication, calendar, hosting, or maintenance tools. They are not sold.

6. Trackers and local storage

Currently configured, the site does not set any cookies and does not write any information to your browser's local storage or session storage. It does not use any advertising trackers or analytics tools. Links to external services only load these services after your click.

The code includes an optional integration with Google Analytics 4, which is disabled until a measurement ID is configured. If enabled, the Google tag is loaded only after your explicit consent. Refusal is offered with the same ease as acceptance and can be modified through the preferences button. Your choice is stored locally under the key mellion-analytics-consent. Before any production activation, the parameters, durations, recipients, and transfers must be validated and specified in this policy.

The font families are hosted on the domain mellion.fr: no request is sent to a third-party service to display them.

7. Third-party services and data transfers

Links to Google Calendar and LinkedIn take you away from this site. Google, LinkedIn, and Netlify may process data outside the European Economic Area according to their own terms and the transfer mechanisms they declare. We invite you to review their privacy policies before use.

The form relies on Netlify’s native anti-robot protection and an invisible trap field. No Google verification services are loaded by this page.

8. Your Rights

Depending on your situation, you can request access, rectification, deletion, or portability of your data, restriction of processing, or object to processing based on legitimate interest. You can exercise these rights at the address oscardessein@mellion.fr. Proof of identity will only be requested in case of a reasonable doubt about the author of the request.

If you believe, after contacting us, that your rights are not being respected, you can lodge a complaint with the CNIL.

9. Changes to this policy

This policy can be updated to reflect changes to the site, service providers, or legal framework. The revision date is indicated at the top of the page. Any significant modification affecting the use of your data will be communicated appropriately.
