Billing, Refund & Chargeback Terms

Version 1.0.0 · Effective February 27, 2026

These Billing, Refund & Chargeback Terms (“Billing Terms”) govern all purchases, payments, refunds, and billing disputes related to your use of the Contia platform (“Service”), operated by Contia (“Company,” “we,” “us,” or “our”). These Billing Terms supplement and are incorporated into our Terms of Service. Capitalized terms not defined herein have the meanings assigned in the Terms of Service.

1. Credit-Based Model

Contia operates on a prepaid credit-based billing model. To use paid features of the Service, you must first purchase credits (“top-ups”) that are added to your workspace balance. Credit balances are displayed in United States Dollars (USD). Credits represent a prepaid entitlement to consume Service resources and do not constitute a deposit, stored value, currency, or any form of property interest. We may, at our sole discretion, adjust the denomination or display currency of credits in the future.

2. Payment Methods

We accept payments through the following third-party payment processors:

  • Stripe, Inc.— Credit cards, debit cards, and other payment methods supported by Stripe. Payments are processed in USD. Stripe payments are collected directly by Contia.
  • YooKassa (YooMoney)— Russian payment methods, including bank cards, e-wallets, SBP (fast payments), and other instruments supported by YooKassa. Payments are processed in Russian Rubles (RUB). YooKassa payments are collected by our authorized billing agent on behalf of Contia.
  • Kaspi Pay— Payment methods available in the Republic of Kazakhstan. Payments are processed in Kazakhstani Tenge (KZT). Kaspi Pay payments are collected by our authorized billing agent on behalf of Contia.

Certain payments may be collected by an affiliated entity acting as our authorized billing agent. In such cases, the billing agent collects payments on behalf of Contia and your contractual relationship remains solely with Contia as defined in these Billing Terms and the Terms of Service. The billing agent does not assume any obligations under the Terms of Service or any other agreement between you and Contia.

All payments are subject to the terms and conditions of the applicable payment processor. By submitting a payment, you represent and warrant that you are authorized to use the selected payment method and that the information you provide is accurate and complete. We are not responsible for errors, delays, or failures caused by third-party payment processors.

3. Foreign Exchange Handling

For payments made in currencies other than USD (including Russian Rubles (RUB) through YooKassa and Kazakhstani Tenge (KZT) through Kaspi Pay), the exchange rate to USD is determined and locked at the time of purchase. The applicable exchange rate and the equivalent USD credit amount are displayed to you before you confirm the transaction. Once a purchase is confirmed, the exchange rate is final and will not be adjusted for subsequent fluctuations in currency markets. We do not guarantee any particular exchange rate and may apply a margin to the prevailing market rate to account for processing costs and currency risk.

4. Credit Balance

Credits are stored at the workspace level. Each workspace (whether personal or team) maintains its own independent credit balance. Credits are:

  • Non-transferable between workspaces, including between a personal workspace and a team workspace, or between two team workspaces, even if owned or administered by the same user.
  • Non-transferable between user accounts.
  • Not redeemable for cash, monetary value, or any other consideration, except as expressly set forth in these Billing Terms.

You are solely responsible for monitoring your credit balance and managing its use within your workspace. We are not liable for unauthorized consumption of credits by workspace members you have invited.

5. Usage Charges

Credits are consumed each time you submit a generation request through the Service. The credit cost for each generation depends on the model selected, the parameters configured (such as resolution, duration, and number of outputs), and any additional options enabled. The exact credit cost is calculated and displayed to you before you submit a generation request. By confirming a submission, you authorize the deduction of the displayed credit amount from your workspace balance.

If a generation fails due to a provider-side error (not attributable to invalid inputs or user error), the consumed credits will be automatically refunded to your workspace balance.

6. Pricing Changes

We reserve the right to modify credit pricing (the cost to purchase credits) and consumption rates (the credits required per generation) at any time. We will provide at least thirty (30) days' prior notice of any pricing change by posting the updated pricing on the Service or by sending notice to the email address associated with your account. Pricing changes will not affect credits that have already been purchased; existing credits in your workspace balance will retain their full value regardless of any subsequent pricing adjustment. Your continued use of the Service after a pricing change takes effect constitutes your acceptance of the updated pricing.

7. Refund Policy

You may request a refund for a credit top-up within fourteen (14) calendar days of the purchase date, subject to the following conditions:

  • Unused credits only. Refunds are available only for top-ups where no credits from the purchased amount have been consumed. If any credits from a top-up have been used, that top-up is non-refundable, in whole or in part.
  • Refund method. Refunds are issued to the original payment method used for the purchase. Processing times depend on your payment provider and are outside our control.
  • Single request per top-up. Each top-up may only be the subject of one refund request.
  • Abuse prevention. We reserve the right to deny refund requests if we detect a pattern of abuse, including but not limited to repeated purchases and refunds, or purchases made with the intent to exploit promotional offers.

To request a refund, contact us at billing@contia.app with your account email, the date of purchase, and the transaction identifier. We will process eligible refund requests within ten (10) business days.

8. Chargebacks

A chargeback (also known as a payment dispute) occurs when you contest a charge with your payment provider rather than contacting us directly. We take chargebacks seriously and address them as follows:

  • Suspension of service. Upon receiving notice of a chargeback, we may immediately suspend access to the Service for the affected account and workspace pending resolution of the dispute. Any credits associated with the disputed transaction will be placed on hold during the investigation.
  • Investigation. We will cooperate with the payment processor to investigate the chargeback and will provide evidence of the transaction as appropriate.
  • Fraudulent chargebacks. If a chargeback is determined to be fraudulent, filed in bad faith, or filed without first attempting to resolve the issue through our billing support, we reserve the right to permanently terminate your account and forfeit any remaining credit balance without further notice or liability.
  • Recovery of losses. We reserve the right to pursue recovery of any losses resulting from fraudulent or abusive chargebacks, including chargeback fees assessed by payment processors, through lawful means.

We strongly encourage you to contact billing@contia.app before initiating a chargeback with your payment provider. Most billing issues can be resolved more quickly through direct communication.

9. Tax Responsibility

All prices displayed on the Service are exclusive of taxes unless otherwise stated. You are solely responsible for determining and paying any applicable taxes, duties, levies, or similar governmental assessments arising from your purchase of credits or use of the Service, including but not limited to value-added tax (VAT), goods and services tax (GST), sales tax, or withholding tax. We may collect and remit taxes on your behalf where required by applicable law, in which case the tax amount will be added to the purchase total at checkout.

10. Credit Expiration

Credits purchased through paid top-ups do not expire. Purchased credits remain available in your workspace balance indefinitely, subject to the other provisions of these Billing Terms (including forfeiture upon account closure and the terms governing promotional credits). We reserve the right to introduce expiration terms for credits in the future, with at least ninety (90) days' prior notice; any such change will apply only to credits purchased after the change takes effect.

11. Account Closure

If you voluntarily close your account or request deletion of your workspace, any remaining unused credits in the associated workspace balance are forfeited and will not be refunded. You acknowledge and agree that it is your responsibility to utilize or request a refund for eligible credits prior to initiating account closure. This provision does not apply where prohibited by applicable law; in such jurisdictions, we will comply with the relevant statutory requirements regarding unredeemed balances.

12. Free and Promotional Credits

We may, from time to time, offer free or promotional credits as part of marketing campaigns, referral programs, beta participation, or other initiatives. Such credits:

  • May be subject to separate terms, conditions, and restrictions as communicated at the time of issuance.
  • May have an expiration date, after which unused promotional credits will be automatically removed from your workspace balance without notice or compensation.
  • Are consumed before purchased credits unless otherwise specified.
  • Are not eligible for refund, cash-out, or transfer under any circumstances.
  • May be revoked if obtained through fraud, abuse, or violation of the applicable promotional terms.

13. Billing Disputes

If you believe there is an error on your billing statement or have questions about a charge, please contact our billing support team at billing@contia.app. Please include the following information in your inquiry:

  • Your account email address.
  • The date and amount of the charge in question.
  • A description of the issue or the reason you believe the charge is incorrect.
  • Any relevant transaction identifiers or receipts.

We will acknowledge receipt of your dispute within two (2) business days and aim to resolve billing disputes within ten (10) business days. During the investigation of a billing dispute, your access to the Service will not be suspended unless a chargeback has been filed (see Section 8).

Changes to These Billing Terms

We may update these Billing Terms from time to time. If we make material changes, we will notify you by posting the updated terms on the Service and updating the effective date above. Your continued use of the Service after any changes take effect constitutes your acceptance of the revised Billing Terms. We encourage you to review these Billing Terms periodically.
