idun-group.com uses cookies and similar technologies (localStorage). This policy details the trackers set on your device and how to manage your consent, in line with article 82 of the French Data Protection Act and CNIL recommendations.
A cookie is a small file placed by a website on your device during your visit. It can store a preference, authenticate a session or help measure site audience.
No advertising cookies are set on this site. Three kinds of trackers may be present: (1) the strictly necessary storage of your consent choice (for the site and for PostHog), (2) the local storage of your preferences (language, theme), which is not used to measure audience, and (3) audience-measurement cookies and storage, PostHog and Google Analytics, set only after your explicit consent. With that consent, PostHog also records how your visit unfolds (session recording, detailed in our privacy policy).
If you reject them, your visit is still counted, without any cookie or audience-measurement storage (only your choice is stored): PostHog computes a fingerprint on its servers from your IP address and browser, with a key that is renewed every day and then deleted. This fingerprint therefore cannot link two visits on different days, nor be traced back to the IP address. What is sent at that level: the pages viewed (address, title, duration), the source of the visit, including the parameters of the link you followed, and the browser's technical characteristics; no clicks, no input, no session recording (replay).
The table below lists all cookies and local storage entries that may be set on your device during your visit.
| Name | Provider | Purpose | Duration | Category |
|---|---|---|---|---|
| idun_consent_v1 (localStorage) | idun-group.com | Stores your cookie consent choice (accept, reject, or customised settings) | 12 months, after which the banner is shown again | Strictly necessary |
| __ph_opt_in_out_<project-key> (localStorage) | idun-group.com (set by posthog-js) | Stores your choice for PostHog (accept or reject) | Until you change your choice | Strictly necessary |
| ph_<project-key>_posthog | idun-group.com (set by posthog-js) | Random browser identifier and visit properties (including the company of a link we sent) for PostHog audience measurement | 12 months after the last visit | Analytics |
| ph_<project-key>_posthog (localStorage) | idun-group.com | Persistent PostHog properties (same purposes as the cookie above) | Until you withdraw consent | Analytics |
| idun_locale, idun-locale-suggestion-dismissed, idun-theme (localStorage) | idun-group.com | Stores your preferences: language, dismissed language banner, display theme | Until you clear them in your browser | Functional |
| ph_<project-key>_window_id, ph_<project-key>_primary_window_exists, ph_<project-key>_posthog (sessionStorage) | idun-group.com (set by posthog-js) | Tab identifier and PostHog session state, for audience measurement and session recording | Until the tab is closed | Analytics |
| _ga | idun-group.com (set by Google Analytics) | Random browser identifier for Google Analytics audience measurement | 13 months after the last visit | Analytics |
| _ga_<measurement-id> | idun-group.com (set by Google Analytics) | Session state for Google Analytics audience measurement | 13 months after the last visit | Analytics |
On your first visit, a banner lets you choose between "Accept all", "Reject all" and detailed settings. Your choice is stored for 12 months; after that, the banner is shown again and audience measurement stays paused until you choose again.
You can change your preferences at any time via the "Cookie preferences" link in the site footer, or from the button below. If you withdraw your consent, the audience-measurement cookies and storage are deleted.
Refusing analytics cookies has no impact on your access to the site or on navigation.
All modern browsers let you configure cookie placement through their settings. The procedure varies by browser:
Chrome → Settings → Privacy and security → Cookies and other site data.
Firefox → Settings → Privacy & Security.
Safari → Preferences → Privacy.
Edge → Settings → Cookies and site permissions.
