Terms of Service

1. Agreement and operator

These terms govern Mutanai, its browser-based character editor, accounts, exports, subscriptions and credit purchases.

Policy version: 2026-10-04-v1

• Service: Mutanai
• data controller: CHEN WEIWEI
• Operator type: Individual developer
• Operator country or jurisdiction: China
• Support, billing and privacy contact: support@mutanai.com

Account holders and purchasers must be at least 18 and able to enter a contract. Keep registration and billing information accurate and protect your credentials. When acting for an organization, you must be authorized to bind it. If you do not accept these terms, do not create an account or purchase the paid service.

Our Privacy Policy explains personal-data handling; optional tracking or marketing consent is separate from this agreement.

2. Service and delivery

You can customize animal and playful 3D character shapes, colors, materials, expressions and accessories. Editing and previews are free. PNG, HTML and asset-pack exports require an account and sufficient credits.

The service supplies digital features and downloads, not physical goods. Once a payment is confirmed, the application grants the purchased credits and, where applicable, activates the subscription. Provider confirmation may take time; a success-page redirect alone is not payment confirmation. If a completed payment does not appear, contact us with the order reference.

PNG exports are static images. Downloaded HTML characters need internet access to load their 3D library. The editor does not offer AI photo conversion, animated GIF export or rigged avatar model files.

Local collections hold up to 24 characters in the current browser and do not synchronize to an account or another device. Download backups; clearing browser data removes the local collection.

3. Plans and credit purchases

Available prices, currencies, billing periods and credit allowances are displayed on the plans page and confirmed at checkout. Monthly and annual subscriptions grant credits after successful payments. One-time credit purchases grant a finite balance and do not automatically replenish it.

A plan or tab labelled “lifetime” refers to the displayed one-time credit allowance with no scheduled credit expiry. It does not mean unlimited exports, recurring credit grants or a promise that the service will operate forever.

New accounts receive 10 welcome credits. Each single PNG or HTML export uses 2 credits; one nine-image asset-pack download uses 18 credits. Previewing a pack is free. Feature costs may change prospectively with appropriate notice and will be shown before a charge.

Credits have no cash value, cannot be transferred between users and can only be used for this service, except where a monetary refund is required or approved.

4. Payments and recurring authorization

When you complete a recurring subscription purchase through Waffo Pancake or another automatic-billing provider, you authorize the recurring charge shown at checkout at each monthly or annual renewal until cancellation. Do not complete checkout if you do not agree to its price or recurring terms.

When offered, Alipay and WeChat Pay purchases are one-time payments for the displayed term and require manual renewal. A one-time credit purchase through any provider does not authorize automatic renewal. The application does not offer balance-triggered automatic top-ups.

Waffo Pancake is Merchant of Record for purchases made through its hosted checkout. It handles payment collection and applicable transaction taxes; the selling entity, final currency and tax-inclusive total are identified at checkout or on the receipt. Our operator supplies and supports the avatar service. Another provider's checkout is governed by that provider's applicable payment terms.

Displayed prices may exclude applicable taxes unless stated otherwise. Review the final total before paying. Charges and billing descriptors can differ from the product's brand name; use the transaction receipt to identify the payment. We will not treat a price change as authorization to charge an undisclosed amount.

5. Credit expiry and cancellations

Subscription credits expire at the end of the billing period recorded for their grant and do not roll into the next period. Current one-time purchased balances and welcome credits have no scheduled expiry. You can inspect your balance and credit history in account settings. Expired, refunded or already-spent credits are not available for further exports.

Credit deductions are recorded against eligible grant batches. Balances without an expiry can be consumed before dated balances; dated balances are considered in expiry order. Consult the transaction history if you need to identify which purchase supplied an export.

You can cancel automatic renewals online in Account settings → Billing → Cancel subscription. Verify the cancellation status and recorded term end. If the online operation fails, promptly email support@mutanai.com from your registered email and include the subscription reference.

Cancellation stops future renewals after the cancellation is accepted by the provider. The current paid term remains available until its end, subject to credit expiry and any refund or suspension. Cancelling does not refund past charges, delete your account or revoke unrelated one-time credits. Closing a browser tab or removing a local character does not cancel a subscription.

6. Service problems and billing disputes

For a missing export, incorrect deduction, duplicate charge or payment not reflected in your account, contact support@mutanai.com with your account email and order or export reference. Do not include full card details. We will investigate the application and provider records and correct confirmed errors.

Contacting support does not remove any right to complain to your payment provider, bank, regulator or court. We do not require you to abandon a lawful dispute as a condition of assistance.

7. Refund policy

For a first paid purchase, request a full refund within 7 calendar days of the charge if none of the credits granted by that purchase have been used. Cancellation alone is not a refund request. Outside this guarantee, used credits and completed export services are generally not refundable, subject to the exceptions below.

We will correct confirmed duplicate or erroneous charges. A paid entitlement not delivered or a material service failure may qualify for a refund, proportionate remedy or other legally required correction after investigation. Mandatory consumer cancellation, withdrawal and refund rights remain available; these terms do not waive them merely because a user starts editing or downloads a file.

Send a request to support@mutanai.com from your account email with the order reference and reason. We aim to acknowledge it within two business days. Approved monetary refunds are processed through the original payment provider and payment method where possible. Provider and bank posting times vary; a refund is not a guarantee of immediate bank credit.

An approved refund removes the unspent credits corresponding to the refunded amount and may adjust the associated entitlement. A refund and cancellation are separate operations: if you also want to stop a recurring plan, cancel it online or explicitly request both. Welcome credits have no purchase price to refund.

For a Waffo purchase, the refund notice shown in Waffo checkout forms part of that transaction. Mandatory legal rights take priority over a conflicting limitation. Contact us or the seller on the receipt if the notices appear inconsistent.

8. Downloads and intellectual property

You retain rights in material you supply. You permit us to process character settings and nickname only as needed to render, export, account for and support the requested service. We do not use those settings to train AI models.

You may use lawfully obtained avatar downloads for personal or commercial profile and design purposes, subject to third-party rights and any licenses included with a download. This does not transfer ownership of the editor, source assets, software libraries or our branding. We do not promise exclusive copyright in a preset, or that similar characters cannot be made by others.

9. Acceptable use

Do not use the service or its exports for illegal activity, fraud, deceptive impersonation, harassment, infringement, or sexual exploitation of children. Do not introduce malware, attempt unauthorized access, bypass payment or credit controls, share account credentials for resale, or disrupt the application. Obtain permission for material or identities belonging to others.

10. Suspension and service changes

We may restrict access to address serious abuse, security risks or legal obligations, with notice and an opportunity to resolve issues where appropriate. Contact support to request account closure; cancelling a subscription is not account closure.

If we discontinue a paid service for reasons unrelated to your breach, we will address prepaid undelivered entitlements through an appropriate refund or legally required remedy. We cannot promise indefinite service availability, but a service change does not remove mandatory consumer rights.

11. Responsibility and applicable law

To the extent permitted by law, the service is offered as available without a guarantee of uninterrupted operation or suitability for every purpose. Keep backups and inspect downloads before relying on them. We do not exclude responsibility that applicable law prohibits us from excluding, including applicable consumer remedies.

Disputes may be raised with support@mutanai.com first, without limiting statutory remedies. The service is operated by an individual developer based in China, as identified above. Mandatory consumer protections and legally required venues remain applicable; no exclusive arbitration or foreign court is imposed by these terms.

12. Changes and contact

We will give reasonable advance notice of material changes affecting an existing paid plan, including changes to renewal charges, through the account email or a prominent service notice where appropriate. Required consent will be requested where the law requires it. Historical purchases remain subject to the applicable purchase terms and mandatory law.
