Privacy policy
Last updated: August 2026
Data we collect
Through the contact form and the slot picker on this site: name, work email address, company name, free-text message and preferred audit slot. Downloading the free guide collects only your email address.
Purpose
This data is used solely to process your request: contacting you back for the free 30-minute audit, sending you the requested guide, or discussing a project. No automated prospecting beyond your request, no data resale.
Audience measurement
This site uses PostHog (European hosting) for audience measurement — page views and navigation paths — only when measurement is enabled in the site configuration. No advertising tracker is loaded on this site.
Retention
Contact requests are kept for the time needed to process your request, then archived for a maximum of 12 months unless a business relationship is ongoing.
Your rights
Under the GDPR, you have rights of access, rectification, deletion and portability. A simple email is enough: mathurin.ache@free.fr. You may also contact your local data protection authority.
