Frequently asked questions
How do I cancel my subscription?
Enter your email above to access the Stripe portal and cancel in one click. You keep access until the end of the current period (Pro or Pseudo). No cancellation fee.
My payment failed — what should I do?
Enter your email above to update your card directly. Stripe retries automatically, but an immediate update avoids any service interruption.
I lost my license key
Use the "Resend my key" form above: any active Pro and/or Pseudo key is resent to your account email, no manual step needed.
Can I change my plan?
Yes — the Stripe portal (above) lets you switch plans. For special cases (Lab plan, promo codes), contact us. View pricing.
What is the 4-year perpetual fallback?
After 48 cumulative months of active subscription, if you cancel, your Pro license remains active indefinitely. It's our commitment to loyal users.
Waiver of the right of withdrawal
In accordance with Article L221-28-13° of the French Consumer Code, you waived your right of withdrawal at the time of subscription (explicit non-pre-checked checkbox on the Stripe payment form). In exchange, the free version of the software — with no time limit and no credit card required — let you evaluate the service before any financial commitment. For any question, contact us at contact@nma-conseil.fr. See the full terms.
