Payments and invoicing

Last updated: 9 September 2026

Who processes the payment

Stripe, a certified payment institution. The card never touches this site: the payment page is Stripe's own, and what comes back to us is the result, the email address and the billing country. We never see, store or transmit card numbers.

What appears on your statement

The charge appears as Caniedu or as the descriptor configured with Stripe for the seller named on the seller page. If you see a charge you do not recognise, write to us before contacting your bank and we will identify it within one working day.

Currencies

The English site charges in US dollars, the Spanish and Portuguese sites charge in euros. If your card is in another currency your bank converts, and that conversion, along with any international transaction fee, is between you and your bank.

Accepted methods

The cards Stripe accepts for this account, shown at checkout. There is no cash on delivery, no bank transfer and no crypto.

One payment

Every plan is charged once. There is no subscription, no renewal, no stored card charged later and no automatic upgrade. If you ever see a second charge you did not authorise, tell us and it is refunded on the spot.

Taxes

Prices are shown as the amount you pay. Where a tax is due on the sale, it is calculated at checkout from your billing address and shown before you confirm. The seller is a Brazilian individual and issues no Brazilian nota fiscal; the receipt Stripe sends is the proof of purchase.

Invoices

Stripe emails a receipt automatically. If you need an invoice with a tax number on it, enter the number in the field at checkout, or write to us afterwards and we issue it by hand.

Failed and pending payments

A declined payment charges nothing and opens no access. A pending authorisation that your bank shows for a few days is released on its own; if it does not, tell us and we ask Stripe to release it.

Security

The site runs on HTTPS. Access to the lessons is a signed token, not a password, so there is no password of yours here to be stolen.
