Cookie policy.

A cookie is a small text file stored on your device when you visit a website. This page explains how the Group Sigma website handles cookies.

Cookies used on this website

This website is a static informational site. It does not use advertising cookies, analytics cookies or third-party tracking tools. No cookie is placed for marketing or profiling purposes.

Only strictly necessary cookies may be used, where applicable, to ensure the basic technical functioning of the site (for example, those potentially set by the hosting provider OVH SAS). These do not require prior consent under the ePrivacy rules.

Consent

Because the site does not use non-essential cookies, no cookie consent banner is displayed. If analytics or other non-essential cookies are added in the future, this policy will be updated and your consent will be requested beforehand.

Managing cookies

You can control and delete cookies through your browser settings at any time. Most browsers let you block cookies or alert you when a cookie is being set. Disabling strictly necessary cookies may affect the basic functioning of the website.
