I create and operate digital programs for general wellness, beauty and lifestyle. Each program is delivered as a browser-based web app with structured video lessons, plans and reference materials. Customers log in with the email they used at purchase and access everything online — there is no physical product and nothing to install.
MmartinsC is not a company. It is the trade name under which Mateus Martins Cardoso de Sá, an individual based in Terra Boa, Paraná, Brazil, sells digital products directly to customers. All contracts, payments and support are handled by the same person named above, at the address and contact details listed on this page.
Payments are processed by a licensed third-party payment provider. Card details are never received or stored by MmartinsC.
MmartinsC serves customers internationally. Core markets are French-speaking regions (including France and Canada) and Spanish-speaking regions, alongside English-speaking customers. Because sales are cross-border, charges may be processed in several currencies, most commonly the Euro; the price and currency are always shown before purchase. Support is available in French, Spanish, English and Portuguese.
I aim for clear pricing, honest descriptions, immediate delivery and responsive support. Programs are educational and intended for general wellness and beauty; they are not medical services, and they do not diagnose, treat or prevent any condition. Complete refund, cancellation, privacy and terms policies are published and linked from every page.
