GDPR and the Loi Informatique et Libertés: The CNIL actively fines non-compliant cookie banners — "Refuse all" must be as visible as "Accept all".
Payment methods customers in France expect: Cartes Bancaires (CB), PayPal, Stripe, Alma (instalments) and Apple Pay.
Interface and content languages: French.

A daily call at 08:00–11:00 your time (12:30–15:30 IST) works year-round. Between calls you get written updates and a staging link that shows the latest build.
