Refund Policy

Last updated: July 2, 2026

All sales are final

Everything we sell is digital content with instant, lifetime access. Because the full value of the product is delivered the moment you can watch or read it, all purchases are final and non-refundable. Once payment is completed, it cannot be reversed, exchanged, or credited.

Billing errors

The only exception is a genuine billing error: if you were charged twice for the same product, or charged without receiving access and our support cannot activate it, contact us within 14 days and we will correct the charge.

Before you buy

Because sales are final, please use the free material before purchasing: every course has a free preview and a detailed description, and every ebook lets you read the first pages at no cost. If you are unsure whether a course fits your level or your tools, ask us first via the contact page or WhatsApp — we will tell you honestly whether it is right for you.

Questions

Email contact@diatronik-france.fr from the address you purchased with, including the product name. We respond within 2 business days.
