What we store on your device, why, and how to change your mind.
Three statistics tools only run once you agree: Google Analytics, Microsoft Clarity and PostHog. Until you choose, they are not loaded and store nothing.
Everything else — your session, payment, address autocomplete, our own visit counter — is required for the site to work and does not need your consent.
We do not run targeted advertising. We do not sell or share this data. We do not track you across other websites.
These are required for the service you asked for. Disabling them would break the site.
| Item | Purpose | Duration |
|---|---|---|
| MCAC session | Keep you signed in, secure the forms | Session only |
| Stripe | Take payment and detect fraud | See Stripe's policy |
| hCaptcha | Stop bots from sending fake requests | Session only |
| Google Maps | Autocomplete your address in the quote form | Session only |
mcac_vid | Our own visit counter (see point 4) | 13 months |
mcac_attribution | Remember how you arrived, so we don't ask twice | Session only |
mcac_cookies | Remember your choice on this page | 12 months |
| Vercel Analytics | Counts page views, no cookie and no personal data | No storage |
These three tools show us which pages genuinely help you and which ones we need to fix. They only load after you click "Accept all" or enable them one by one.
| Tool | Purpose | Duration |
|---|---|---|
| Google Analytics 4 | Count visits, see which pages are viewed and how | Up to 13 months |
| Microsoft Clarity | Spot where visitors get stuck on a page | Up to 13 months |
| PostHog (data hosted in the European Union) | See where a visit gets stuck: pages, clicks, scrolling. What you type in forms is masked | 12 months |
If you accept Google Analytics and then book, your booking is linked to these statistics: its amount and its file reference, nothing else. No name, email or phone number is sent to Google.
If you accept PostHog and then send a request or book a call, your visit is linked to your file reference, so our team understands your request before calling you. No name, email or phone number is sent to PostHog.
Refusing changes nothing for you: same quote, same price.
We count visits ourselves, without any external tool. This measurement stays with us: it is not passed to anyone, not combined with any other file, and cannot follow you across other websites.
As such it falls under the audience-measurement exemption set out by the French data protection authority (CNIL). The identifier used is kept for 13 months at most, then deleted. It is never used for advertising.
If you would rather opt out anyway, email us at contact@mcac.app and we will delete your identifier.
You can change your choice at any time, without giving a reason, using the "Manage my cookies" button at the top of this page.
A refusal is kept for 12 months: we will not ask again on every visit.
You can also delete stored cookies from your browser settings.
You have the right to access, correct, erase, object to and port your data. Our privacy policy covers all processing in detail.
To exercise your rights: contact@mcac.app. You may also contact the CNIL (cnil.fr).
