Personal data
The contact form sends your name, email, company (optional) and message by email to the publisher, solely to reply to your request. This data is not stored on the site. Exchanges are kept for as long as needed to follow up on the request, then for at most 3 years after the last contact.
The free audit stores the website address, your email, your language and a non-reversible fingerprint of your IP address, based on your consent, to run the audit, send you the report and prevent abuse (one audit per address per month). The public content of the analysed website is sent to OpenAI (United States, standard contractual clauses), which does not use API data to train its models. Unconfirmed requests are deleted after 48 hours, reports after 12 months.
If you order the full audit, payment is processed by Stripe (Stripe Payments Europe, Ireland): card details never go through this site. Company name, billing address and email are kept for 10 years to meet accounting obligations.
The forms are protected against spam by Cloudflare Turnstile, which analyses technical browser signals without advertising tracking cookies.
Under the GDPR, you have the right to access, rectify and erase your data by writing to hello@sebastienfontaine.me. You can also contact the French data protection authority (CNIL, cnil.fr).
