What data we collect

Essential cookies and local storage

  • Language preference (site_locale cookie): stores your chosen language (French or English) for up to one year.
  • Cookie consent (martinlechene_cookie_consent in localStorage): records whether you accepted or rejected optional analytics.

These are strictly necessary for site functionality and consent management.

If you click Accept on the cookie banner, we use PostHog (EU hosting) to collect:

  • Page views and navigation paths
  • Locale switches and project link clicks
  • Browser type, device type, and approximate location (country)
  • Session duration

PostHog may set its own cookies and use localStorage. No analytics data is collected if you click Reject.
