Terms of Service | Yinatrix

Welcome to Yinatrix! These Terms of Service ("Terms") apply to your ("you" or "your") use of the Yinatrix platform (the "Service"). By using the Service, you agree that these Terms will become a legally binding agreement between you and WenSiHeYuan, the operator of Yinatrix (the "Operator", "we", "us", or "our"), identified in these Terms.

Summary of Key Terms (please read in full below).

By accessing or using yinatrix.com (the "Service"), you agree to these Terms of Service ("Terms") and our Privacy Policy.
Yinatrix is an AI tool platform that integrates multiple leading third-party AI models. Some outputs are generated by those third-party models and are subject to both these Terms and the model providers' own policies.
AI-generated content is provided "AS IS" and without warranty of accuracy and does not constitute professional advice. You use outputs at your own risk.
Paid plans (monthly or annual) auto-renew until cancelled; fees for the current period are generally non-refundable except as stated in Section 4.
Our total liability is limited to the greater of USD $100 or the fees you paid in the prior 12 months, and we are not liable for indirect, incidental, or consequential damages including lost profits.
We may remove content, restrict, or permanently ban accounts that violate these Terms (Section 9 and Section 14).
Disputes are governed by the laws of the People's Republic of China and subject to the exclusive jurisdiction of the competent courts at the Operator's place of incorporation (subject to mandatory local consumer rights where you reside).
If you do not agree to these Terms, do not use the Service.

2.2 Verification. We may require you to verify your identity, age, or eligibility to use the Service at any time where reasonably necessary to comply with applicable law, protect the Service, prevent fraud or abuse, or enforce these Terms. Failure to complete such verification may result in suspension or termination of your access to the Service.

3. Description of Service

3.1 Overview. Yinatrix is an AI tool platform that integrates multiple industry-leading third-party AI models to provide text, image, audio, video, document, and related generation and editing capabilities.

3.2 Third-Party AI Models. The Service accesses one or more third-party model providers ("Model Providers") through APIs or similar means. You acknowledge and agree that: (a) some outputs are generated by third-party models that we do not control; (b) your prompts and inputs may be transmitted to and processed by those Model Providers according to their own terms and policies; and (c) we make no warranty as to the accuracy, availability, legality, or safety of any third-party model or its outputs.

3.3 Changes, Suspension, Termination. We may, at our discretion and (where practicable) with prior notice, modify, limit, suspend, or discontinue the Service or any feature (including pricing, model availability, and API access) for operational, security, legal, or business reasons. We do not guarantee that the Service will be uninterrupted, error-free, or free of data loss, and are not liable for any such interruptions except as required by law.

3.4 Availability and Backup. The Service is provided "AS IS." You are solely responsible for backing up any content you create or generate. We do not guarantee long-term storage of your data, and data may be deleted and become unrecoverable following termination.

4. Subscription, Billing, Credits, and Refund Policy

4.1 Free and Paid Plans. The Service offers a free tier with limited features and various paid subscriptions ("Subscription" or "Plan"). Fees, features, and limits are shown on our Pricing page and in your order confirmation.

4.2 Plan Types — Monthly and Annual. Subscriptions are offered on a monthly or annual billing cycle. Annual plans are billed in advance for the full year and typically provide a discounted effective monthly rate versus monthly billing. The billing cycle begins on the date of purchase and recurs on the corresponding date each month or year.

4.3 Billing and Payment. Paid plans are processed through third-party payment processors. Your relationship with the processor is governed by its own terms; we are not responsible for the processor's acts or omissions. You must provide valid, authorized billing information and keep it current.

4.4 Auto-Renewal and Cancellation at Expiry. Unless stated otherwise, Subscriptions automatically renew at the end of each billing period, and we will charge the then-current fee without further authorization until you cancel. You may cancel at any time in your account settings. Cancellation takes effect at the end of the current paid period ("cancel at expiry"); your Plan remains active until that period ends, and fees for that period are non-refundable (except where required by law).

4.5 Plan Upgrades and Downgrades.

(a) Upgrade: Upgrading to a higher-tier Plan takes effect immediately. We will charge a prorated amount for the remainder of the current period (the new higher rate less any unused portion of the prior Plan), and subsequent renewals bill at the new rate.
(b) Downgrade: Downgrading takes effect at the end of the current paid period; your current Plan stays active until then, and we do not refund the difference for the unused portion of the higher tier.
(c) Changes to usage limits (e.g., adding credits on upgrade) are reflected on the next invoice; removing them does not entitle you to a refund of amounts already paid.

4.6 Price Changes. We reserve the right to change the prices and plans at any time. We may change fees upon notice. Increases apply at renewal or after at least 30 days' notice; if you do not accept the new price, you may cancel before it takes effect. Continued use after a price change constitutes acceptance.

4.7 Free Tier. We offer a free tier to allow users to experience some commonly used AI tools; you can stay indefinitely without purchasing a paid plan.

(a) Free tier features and limitations: The features and limitations of the free tier are provided and published at our discretion and may include, without limitation: restrictions on available output types or formats (for example, certain formats such as video may not be available); visible watermarks or other marks applied to generated content; lower processing priority; credit or usage caps; and limitation to non-commercial use. The free tier carries certain limitations relative to paid plans. To remove these limitations, subscribe to a paid plan.
(b) Subject to publication and subject to change: The specific restrictions in effect at that time are set forth in our pricing/feature pages (incorporated by reference) and may be changed at any time in accordance with Section 16.
(c) Not subject to free tier restrictions during the paid period: During the valid paid subscription period, your use is subject to the limitations of your Plan's current features and is not subject to the above free tier restrictions (for example, when your Plan includes watermark-free output, the generated content does not have the free tier watermark). After cancelling or downgrading back to the free tier, its restrictions will apply again to subsequent activities.

4.8 Credits.

(a) Acquisition: Credits may be granted by (i) purchasing a Plan that includes them; (ii) recharge credits (top-up packages); (iii) promotional offers, bonuses, or loyalty/reward programs; or (iv) referrals or other campaigns we run.
(b) Use and Expiry: Credits are consumed as you use metered features. Unless stated otherwise at the time of issuance, credits are permanently valid. We may also periodically distribute credits with validity periods as described in (a), and the specific validity period of each credits distribution will be determined at the time of distribution. Expired credits are forfeited without refund or compensation.
(c) Nature and transfer: Credits constitute a limited, personal, non-transferable permission to use the Service's metered features. They are not a stored-value, gift, or prepaid instrument and have no cash value apart from the Service. Credits may not be sold, assigned, gifted, or traded. We may adjust credit balances, issuance, validity, or limits at our discretion and in accordance with applicable law.

4.9 Refund Policy and Process.

(a) General rule: Except as required by law or expressly stated here, fees for a current period are non-refundable.
(b) Our fault: If we cannot provide a paid feature for the whole period through our fault, we will migrate you to a comparable feature or refund the corresponding portion of the period.
(c) Process: To request a refund where one is owed, contact support@yinatrix.com within the eligibility window stated in your Plan. We will review and, if approved, issue the refund to your original payment method within 3 business days. Refunds may require your account to be in good standing and may be subject to verification.
(d) Pricing errors: We may refuse or cancel any order affected by a pricing, description, or typographical error and refund the amount charged without an obligation to sell at the erroneous price.

4.10 Non-Refundable Circumstances. Refunds will not be provided where:

(a) you have used or substantially used the Service/features in the current period (e.g., generated outputs, consumed credits);
(b) you request a refund simply because you no longer wish to use the Service after the cancellation-at-expiry point;
(c) the request relates to consumed, expired, or promotional/free credits;
(d) termination is due to your breach of these Terms;
(e) you accepted a non-refundable promotional or discounted offer that explicitly stated so; or
(f) applicable law mandates otherwise (in which case the legal minimum applies).

5. Intellectual Property Policy

5.1 Our Intellectual Property. The Service, including its software, design, branding, and "Yinatrix" trademarks, and all related intellectual property, are owned by us or our licensors. We grant you a limited, non-exclusive, non-transferable, revocable license to use the Service for its intended purpose during the term.

5.2 Your Content — Ownership. "Your Content" means any content you input, upload, or generate through the Service. As between you and WenSiHeYuan, you retain all rights, title, and interest in Your Content, subject to the licenses you grant below.

5.3 License to Your Content. To operate and improve the Service, you grant us a worldwide, royalty-free, non-exclusive license to host, store, reproduce, display, modify (as necessary to render), and process Your Content, and to share it with Model Providers solely as required to generate outputs you request. This license survives termination only as needed to operate the Service and comply with law.

5.4 AI-Generated Outputs — Rights and License.

(a) Free tier. Outputs you generate on a free plan are licensed to you for non-commercial use only.
(b) Paid Subscribers. Subject to your compliance with these Terms and payment of applicable fees, and to the extent permitted by applicable law, you may use paid-tier Outputs for commercial purposes. We do not claim ownership of Outputs, and we grant you a worldwide, non-exclusive license to use, reproduce, and share them.
(c) No guarantee of IP rights. The availability, ownership, or enforceability of intellectual-property rights in AI-generated content varies by jurisdiction and may not be recognized everywhere (for example, some jurisdictions require human authorship). We make no representation that any Output is eligible for copyright or other protection, and you are responsible for determining your rights before relying on an Output.

5.5 Third-Party and Licensed Content. Outputs may incorporate or result from third-party models, datasets, or licensed material whose rights remain with their owners and are subject to the Model Providers' terms. Your use of such content must comply with those terms.

5.6 Feedback. If you submit ideas, suggestions, or feedback, you agree we may use them without restriction or compensation, and (to the extent permitted by law) you assign to us all right, title, and interest in such feedback.

5.7 Trademark Policy. "Yinatrix" and related marks are our trademarks. You must not use the Service to generate, reproduce, or use content that infringes any third party's trademark, trade dress, logo, brand name, or slogan (for example, generating a brand's logo, mimicking a company's visual identity, or using protected marks to imply endorsement). We may remove such content and, in cases of repeat or wilful infringement, restrict or terminate your account. Trademark owners may report suspected infringement through the process in Section 15.

6. Your Content and Personal Data

6.1 Responsibility for Content. You are solely responsible for Your Content and for ensuring you have the rights to provide it. You represent that Your Content does not infringe any third party's rights or violate any law.

6.2 Use of Your Content to Train Models. We will not use Your Content or prompts to train our own or third-party foundation models without your separate, affirmative consent. Model Providers may process Your Content solely to generate the outputs you request, as described in their policies.

6.3 Privacy and Data Role. Our handling of personal data is governed by the Privacy Policy. We act as the controller of personal data we process in connection with your use of the Service (for example, your account, analytics, and generating the outputs you request). Where your prompts or content are transmitted to third-party Model Providers to generate outputs, those providers process the data under their own policies, as described in the Privacy Policy.

6.4 Cross-Border Data Transfers. The Service integrates third-party AI models and may be supported by infrastructure located outside your country of residence. Accordingly, Your Content and personal data may be transferred to and processed in countries other than your own, including the United States and other jurisdictions whose data-protection laws differ from those of your home country. The Operator may also be established outside your country of residence, and Personal Data accessed or processed by the Operator's systems is subject to the same safeguards described in the Privacy Policy. By using the Service, you consent to such transfers as described in the Privacy Policy, which implements appropriate safeguards (such as contractual clauses) where required by law.

6.5 Retention, Deletion, and Export. You may export Your Content while your account is in good standing. Upon termination, we will handle Your Content per the Privacy Policy; we are not liable for loss of data you fail to export in time.
