Payments and Refunds

This policy governs purchases, credits, and refunds related to Lingot, a service provided by MAVILIO Corporation, Japan.

For payment questions, you can write to support@lingot.net.

1. Lings credits

Lingot works through credits called Lings.

Lings can be purchased and used to access AI functions, sessions, conversations, exercises, audio, corrections, teaching content, or other functions available in the service.

Lings consumption may vary depending on the type of activity, duration, AI model, technical cost, service settings, or operating conditions.

Lings are not electronic money, have no monetary value outside Lingot, are not transferable, and cannot be converted into cash.

Unless otherwise indicated at the time of purchase, purchased Lings expire 12 months after the purchase date.

2. Payments

Payments are handled through Stripe or other providers indicated at the time of purchase.

Lingot does not store full payment card data.

The user is responsible for checking the amount, currency, purchased package, and payment method before completing the purchase.

Any taxes, bank fees, currency exchange costs, or costs applied by the payment provider may depend on the user's country, bank, or payment method.

3. Digital nature of the service

Lingot provides a digital service with credits that can be used immediately after purchase.

For this reason, once payment has been completed and Lings have been made available, purchases are not refundable, except as required by applicable law or by the exceptions indicated in this policy.

4. No refund for use or non-use

Refunds are not provided for:

  • Lings already used;
  • Lings not used before expiration;
  • failure by the user to use the service;
  • change of mind after purchase;
  • learning results not achieved;
  • subjective dissatisfaction with AI responses, exercises, or corrections;
  • user errors in choosing the package;
  • suspension or closure of the account for abuse or violation of the Terms of Service.
5. Possible exceptions

We may evaluate a full or partial refund only in limited cases, for example:

  • clear duplicate charge;
  • verifiable unauthorized payment;
  • serious technical error attributable to Lingot that prevents crediting the purchased Lings;
  • obligation required by applicable law.

The request must be sent to support@lingot.net with the account email, payment date, amount, payment method, and description of the problem.

Evaluation does not automatically guarantee a refund.

6. Technical problems

If a technical problem temporarily prevents use of the service, Lingot may, at its discretion, restore Lings, correct the balance, offer replacement credit, or propose another reasonable solution.

A temporary interruption, an AI error, or a service slowdown does not automatically create a right to a refund.

7. Chargebacks and disputes

If the user opens a dispute or chargeback through a bank, card, or payment provider, Lingot may suspend the account or limit access until the dispute is resolved.

In case of fraudulent chargeback, abuse, or violation of the Terms, Lingot may close the account and block remaining Lings.

8. Changes to prices and packages

We may modify prices, packages, promotions, limits, functions, and Lings consumption methods.

Changes do not create a right to a refund for purchases already completed, except for mandatory legal obligations.
