Refund Policy

1. What this policy covers

This Refund Policy explains when Vessara LLC refunds money paid for credits on our learning platform. It applies to every purchase made through this website.

You do not have to pay anything to find out whether the service suits you. Anyone can take three complete lessons without an account and without a card, using the models that cost nothing to run. Please use that trial before you buy credits — a refund cannot give you back the time, and the trial can tell you the same thing in ten minutes.

2. How you pay for a lesson

Understanding the refund rules is easier once the billing is clear, because what you spend is tied to the model you pick.

You choose which model teaches you, and that choice decides the price:

• Free models cost nothing to run, so we charge nothing for them. No credits are taken, and there is nothing to refund.
• Paid models on credits are charged at what the provider actually billed us for that call. A small model can come to a single credit; a frontier model can come to several. A credit is one US cent.
• A subscription plan, where one is active on your account, spends one of the month's included generations per call instead of money, whichever model wrote the lesson.

This is why credits are consumed as you learn rather than held against a fixed price list: the moment a lesson is written or an answer is graded, we have already paid a third-party AI provider for that work.

3. What we refund

Credits do not expire while your account is open, so there is no deadline by which you must spend them. The 30-day limit applies only to asking for money back.

4. What we do not refund

5. When a call fails

If a model returns nothing or fails mid-lesson, we release the reservation for that call: a plan gets its generation back, and a balance is not charged. You should not need to ask for this, and you are never billed for output you did not receive.

If you believe you were charged for something that failed, tell us the lesson and roughly when it happened. Your balance history records every charge, which makes this quick to check.

6. How to request a refund

We answer refund requests within 5–7 business days.

7. How a refund is paid

• Approved refunds are issued to the original payment method
• We send them within 7–10 business days of approving the request
• Your bank may take a further 5–7 business days to post the money
• The refunded credits are removed from your balance when the refund is issued

If your card is billed in a currency other than the one you paid in, the exchange rate on the day of the refund may differ from the rate on the day of purchase. We refund the original amount in the original currency and cannot cover that difference.

8. Cases we look at individually

We may refund outside the rules above when:

• The service was down for long enough to stop you using credits you had bought
• A fault on our side spent your credits without producing a lesson
• You were charged twice for the same purchase

These are decided case by case. Ask, and tell us what happened.

10. Changes to this policy

We may update this policy. Changes take effect when they are published here and apply to purchases made after that date; a refund is always judged by the policy in force when you paid.
