3. Service Subscription, Fees and Usage Rules

The Service is provided by Zettlab as a paid service. The service plans and related rules, including service categories, product benefits, billing models, prices, refund conditions, availability of automatic renewal and billing cycles, will be published by us through official channels. The version in effect on the relevant information page and order page at the time of purchase will control.

3.1 Payment Rules

You shall pay the full service fee for the applicable Order in a single online transaction through the designated online channel within the agreed period and in accordance with the Service pricing. The fee is calculated according to the Service you select. Unless otherwise provided in this Agreement, the page rules, a separate agreement between the parties or applicable law, the fee will not be adjusted automatically based on whether you actually use the Service. An Order becomes effective when payment is successfully completed, and Zettlab will activate the corresponding Service after receiving the full service fee.

Before purchasing the Service, you should carefully review the service content, price, subscription period and other information for the plan you intend to purchase, and complete payment through a channel designated by Zettlab. The payment methods currently available are:

1. In-App Purchase through the Apple App Store;

2. Stripe;

3. Visa, Mastercard, American Express, JCB and other supported bank cards; and

4. PayPal.

Zettlab may designate additional payment methods in the future.

For subscriptions, Zettlab will issue an invoice or receipt for the corresponding amount in accordance with applicable tax laws and regulations. Please note that where you purchase through the Apple App Store, Stripe, PayPal, a card issuer or another third-party payment channel, the ability to issue an invoice or receipt may be subject to that provider’s capabilities and procedures. Zettlab will provide reasonable assistance with invoicing where lawful and feasible.

3.2 Subscription Term

The term of the Service is based on the period selected when you place the Order. It begins on the date payment is completed and Zettlab activates the Service through its system and ends on the expiration date of the subscription period. The term will not be extended because you did not use the Service or for other reasons, and the Service you purchase may be used only during the subscription term. If you wish to continue using the Service after the subscription expires, you must place a new Order before expiration to maintain uninterrupted access. If the subscription expires without renewal, the corresponding subscription benefits will automatically terminate and the related Credits will simultaneously expire and be reset to zero.

3.3 Credit Consumption Rules

3.3.1 Consumption logic: Credits are consumed on a usage basis. When you start a conversation, submit a request, execute a task or invoke an AI-related capability, Credits will be deducted automatically based on the actual consumption of that task. Multi-step tasks, long-context interactions, tool calls and file reading may all consume Credits. The detailed consumption rates, the entry point for viewing consumption records and the statistical methodology are subject to the information displayed on the official product pages.

3.3.2 Generated output: Although we use reasonable efforts, the current limitations of artificial intelligence and large-model technology mean that we cannot guarantee that the Service or any model will meet your individualized or specific needs. Credits are deducted according to actual resource consumption after you initiate a conversation or request. Whether Credits are deducted, and how many are deducted, does not depend on your subjective satisfaction with the generated content. Even if AI output does not meet your expectations, Credits already consumed will not be refunded. The refund rules in Section 7 apply only where abnormal Credit deductions result from Zettlab’s material fault or a material defect in the Service.

3.4.3 Consumption priority: Where a User holds different types of Credits, such as Subscription Plan Credits, recharge Credits and bonus Credits, the system will first consume Subscription Plan Credits and, after those are exhausted, will automatically consume bonus Credits. The system will display the available balance, applicable expiration date and consumption details for these two categories of Credits. We confirm that expiration of Subscription Plan Credits does not mean that all Credits in the Account are cleared; these benefits are independent of one another. If the page rules provide otherwise regarding the order of consumption, validity periods or applicable scenarios for different types of Credits, those page rules will control.

3.5 Credit Top-Up Packs

A Credit Top-Up Pack is a one-time package of credit resources purchased separately from a Subscription Plan. After making a one-time payment, the User receives a fixed number of Credits. A Credit Top-Up Pack takes effect immediately after a successful purchase and can be used permanently. Any unused Credits will automatically expire when the validity period ends. Unless otherwise provided on the purchase page, in the campaign rules, in the refund policy in this Agreement or by applicable law, a Credit Top-Up Pack is non-refundable and may not be converted to cash after purchase and activation.

3.6 Bonus Credits

A User may receive permanent bonus Credits by binding a new device to the Account. The bonus for each eligible device is currently set at 10,000 Credits. If the same Account binds multiple eligible new devices, bonus Credits will be awarded in multiple rounds according to the number of eligible new devices bound.

Once a device has been bound, if the User unbinds it and later binds the same device to an Account again, it will not be treated as a new device and will not trigger another bonus under this section. Similarly, if a device is restored to factory settings and then bound to an Account again, it will not be treated as a new device and no bonus Credits will be awarded for that device.

3.7 Service Limitations When Credits Are Insufficient

When the Credit balance is insufficient, the system will not block the User’s access to basic information such as devices, Orders, subscriptions, balances, chat history and task records, nor will it use payment pop-ups to block management operations. We will display a prompt only when the combined available Subscription Plan Credits and permanent bonus Credits are insufficient to perform the requested operation.

3.8 Cloud Computer Recharge Rules

The Cloud Computer service hereunder is provided based on Alibaba Cloud server resources. Fees are calculated on a combined basis of resources including storage, computing power and running memory, and no separate fee shall be charged for traffic resources. Storage specifications are available in two tiers of 32GB and 256GB for your selection as needed.

Payment cycles include monthly payment and annual payment. Under the monthly payment model, service fees are charged by calendar month. Payment methods shall be consistent with those for credits recharge as set forth above.You may also use a redemption code to experience the service first before proceeding with formal payment.

The billing system for Cloud Computer and the Credits system are independent of each other as two parallel settlement systems, and no mutual offset between them is allowed.

 

4. Automatic Renewal Rules

Automatic renewal is an optional service that you may actively choose in order to avoid an interruption in access if you forget or are otherwise unable to renew on time.

4.1 Automatic Billing

If you select a monthly or annual automatic-renewal plan and enable automatic renewal, you authorize Zettlab or a third-party payment provider engaged by Zettlab, including the Apple App Store, Stripe, PayPal or a card acquirer where applicable, to automatically charge the service fee for the next billing period to the payment account you have linked within two calendar days before the end of each subscription billing period, subject to the relevant provider’s processing timelines, and to extend the corresponding subscription term. The amount charged, subscription period and associated benefits are subject to the information displayed on the activation page, Order page and payment provider’s interface. If a charge fails because of insufficient funds, an abnormal account status, payment-channel restrictions, network problems or similar circumstances, Zettlab may suspend or terminate automatic renewal and handle your service benefits in accordance with the rules applicable to subscription expiration.

To keep you informed, before the end of each billing period Zettlab will send you a reminder that automatic renewal is approaching through one or more channels, such as SMS, in-app messages, client push notifications, email, payment-provider notifications or other conspicuous means. You must keep your contact information accurate and valid, monitor relevant notices and ensure that sufficient funds are available in your payment account.

4.2 Cancellation or Modification Instructions

You may cancel or modify automatic renewal at any time. You may cancel through the following methods:

1. Within the Zettlab Memo product, go to the Billing Management page and cancel the subscription.

2. Apple App Store (iOS): go to Apple Store > Apple ID profile > Subscriptions, select the applicable subscription and cancel it.

3. PayPal: go to Setting > Payments > Automatic payments(or Suscriptions) >Cancel, select the applicable automatic payment and cancel it.

4. Stripe or bank card: use the subscription-management page or customer portal made available by Zettlab or Stripe. If you cannot locate the applicable option, contact Zettlab through the contact details in Section 12.

The above paths may change as payment providers update their platforms. The actual page displayed by the relevant payment provider will control.

4.3 Effect of Cancellation

If you wish to cancel automatic renewal and avoid a charge for the next period, you must complete cancellation at least two calendar days before the current billing period expires, or by any earlier deadline required by the relevant payment provider (for example, Apple’s subscription cancellation rules). If you cancel only within one calendar day before expiration, the next period’s fee may already have been charged. Successful cancellation of automatic renewal will not affect your right to continue using the current paid period before it expires; after the current period ends, Zettlab will not automatically renew the Service. The status of automatic renewal may be displayed with a delay because of third-party processing times or system latency. Unless otherwise required by law or provided in this Agreement, service fees already successfully charged for the current period are non-refundable.

4.4 Changes to this Agreement and Price Adjustments

Zettlab may modify these rules and the automatic-renewal price in response to business developments or changes in law. If the price changes, we will notify you in a conspicuous manner before the charge. If you do not expressly agree, your automatic-renewal service will automatically terminate at the end of the current period.

4.55 Cloud Computer Renewal Rules

Upon the expiry of the service term, there shall be a 7-day resource retention period, during which you may complete renewal and resume the Cloud Computer service. If you fail to complete renewal upon the expiry of the retention period, the service resources will be automatically released, and Wuyun shall not retain such resources separately. Wuyun shall send notification reminders to you via pop-up window, email and SMS prior to service expiry and resource erasure if you elect not to renew upon the end of the retention period.

 

5. User Account Management

You should keep your Account and password secure and must not disclose them to any third party. Except where otherwise required by law or where we are at fault, you are responsible for the consequences of any theft of your Account or loss of benefits caused by your own actions.

The same user may hold one or more Zettlab Memo Accounts. Each Account is independent, and benefits are not shared between Accounts. Benefits associated with the same Account may be shared across Zettlab Memo platforms, including the PC client, mobile app. Where Zettlab Memo Accounts are linked to different mobile numbers, even if they are used by the same person, top-up records and subscription benefits associated with those Accounts may not be transferred, gifted, sold, leased or shared. Please distinguish between Accounts when logging in, making purchases or participating in activities to avoid financial loss.

6. User Conduct

6.1 You acknowledge and agree that you should not purchase the Service through unofficial channels. Upon purchasing the Service, you obtain only a personal right to use the Service, and that right is limited to you. Without Zettlab’s permission, you may not provide your Account to any third party outside the authorized scope, including by transferring, leasing, lending, sharing or selling the Account. You also may not activate or use the Service for yourself or others through any of the following methods. If you violate these requirements, Zettlab may take one or more measures, including without limitation restricting or disabling certain features, clearing benefits, suspending or terminating the Service, restricting purchase privileges, cancelling automatic renewal or banning the Account, without refunding amounts you have paid. You will be responsible for any temporary or permanent loss of access to some or all features.

(1) using the Service for commercial purposes beyond the scope permitted by the Subscription Plan, such as providing commercialized AI capabilities to third parties;

(2) using robots, crawlers, spam programs, automated scripts or similar tools, or maliciously exploiting or disrupting Zettlab Memo or the rules of related product activities, to activate the Service for yourself or others or to obtain or abuse Credits;

(4) obtaining subscription services through channels other than those designated by Zettlab, including by purchasing, renting, borrowing, sharing or receiving Accounts or benefits;

(6) activating or using the Service in any other manner that violates this Agreement, applicable law or regulatory requirements.

6.2 We may offer marketing and promotional campaigns from time to time, which may include discounts, bonus Credit offers and other benefits. These benefits are limited to the applicable campaign period and may be subject to time limits, total-quantity limits or per-user purchase limits. By participating, you must comply with the relevant campaign rules, act lawfully and refrain from harming the rights and interests of the campaign organizer. If you exploit system vulnerabilities, rule defects, system errors, identity impersonation or similar means to obtain benefits or subscription services unlawfully, such conduct will not be protected by this Agreement. Zettlab may take appropriate action, and you will bear all related risks, losses and legal liability.

6.3 You acknowledge and agree that if Zettlab determines through its own review or a third-party report or complaint that you have violated this Agreement, Zettlab may, taking into account the seriousness of the violation, take one or more of the following measures and notify you in a reasonable manner:

If such conduct causes loss to Zettlab or a third party, you will be liable for compensation.

7. Refund Policy

1. Please choose your top-up amount reasonably based on your actual needs. Except where otherwise required by law, prepaid funds that have not been consumed are not eligible for discretionary refunds.

2. If you violate laws or regulations, harm the lawful rights and interests of the State, the public or others, violate public order or good morals, or breach this Agreement, we may suspend or terminate the Service and will not refund any remaining prepaid amount.

3. For purchases made through the Apple App Store, Stripe, PayPal or a bank card, refunds and chargebacks may also be subject to the rules and procedures of the relevant payment provider. Apple App Store refund requests may need to be submitted to Apple through Apple’s procedures. Zettlab will cooperate as required by applicable law. Nothing in this section limits any consumer right that cannot be excluded or waived under applicable law.

8. Modification, Suspension and Termination of the Service

8.1 Service Modifications

Because internet and artificial-intelligence technologies evolve rapidly, Zettlab may make necessary adjustments to the Service in order to improve the product experience, taking into account business plans and changes in laws and regulatory policy. Such adjustments may include changes to the service name, content, price, features or interface, or replacement of a third-party large-model service.

8.1.1 If an adjustment will affect your normal use of the Service, Zettlab will notify you at least seven calendar days in advance on the relevant service page or by another reasonable method. If an adjustment affects a large number of users or concerns users’ material rights, Zettlab will provide more comprehensive public notice and transition arrangements as required by law.

8.1.2 If you do not accept the adjusted Service and the adjustment materially reduces the features or benefits you have already purchased, you may stop using the affected Service within the period stated in the notice, and Zettlab will calculate the applicable fee on a pro rata basis and refund it through the original payment method.

8.2.2 If the Service is suspended or terminated, Zettlab will notify you through the channels specified in this Agreement, such as SMS or in-app messages.

8.2.3 If the Service cannot be provided normally due to force majeure, technical adjustments by telecommunications operators, interruption of third-party services or other objective circumstances not attributable to Zettlab, Zettlab will promptly notify you and use reasonable efforts to restore the Service. If an interruption results from Zettlab’s failure to perform its statutory security obligations, Zettlab will extend the Service term by an equivalent period.

8.2.4 If the Service must be discontinued entirely for objective reasons such as business adjustments or product withdrawal, Zettlab will publish a prominent notice on the product page at least 30 days in advance in accordance with law. After termination, Zettlab will calculate the fee for the unexpired portion of the subscription term and any unused Credits on a pro rata basis and refund it through the original payment method.

9. Limitation of Liability

9.1 The Service is provided on an “as is” basis during the subscription term. We will use reasonable efforts, in light of available technology and conditions, to maintain the continuity and security of the Service, but we do not guarantee that the Service will be entirely free from defects. A defect that could not have been avoided given the industry’s technical capabilities at the relevant time will not be deemed a breach of this Agreement.

9.2 Except where otherwise required by law or where we act intentionally or with gross negligence, we are not liable for losses caused by your own operations, your device, operating system or network, other third-party reasons, or force majeure.

9.3 To the extent permitted by law, our aggregate liability to you in relation to the Service is limited to the amount you actually paid for the specific Service giving rise to the dispute, unless applicable law provides otherwise as a mandatory requirement.

9.4 After you activate the Service through a channel designated by Zettlab, the specific Service available to you may vary because of differences in your software version, device, operating system, network environment, third-party models, skills, connectors or other third-party factors. Zettlab will provide reasonable assistance to address any inconvenience. However, Zettlab is not responsible for differences caused by your device, operating-system version or other third-party factors.

10. Notices

10.1 Zettlab may send you business notices, service alerts, billing information, payment or renewal notices, verification messages, marketing information, service-rule updates, violation-handling notices and other notices and information through one or more channels, including website notices, mobile SMS, system notifications and pop-up prompts.

A notice or item of information will be deemed delivered if any of the following applies:

(1) if published as a website notice, it is deemed delivered upon publication, unless otherwise stated; or

(2) if sent electronically through a system notification, pop-up prompt, communication tool or similar method, it is deemed delivered upon successful transmission.

If the deemed delivery date falls on a statutory public holiday, delivery will be postponed to the first business day after the holiday.

10.2 Zettlab may send notices through multiple channels so that you can receive them promptly. Zettlab also provides tools for managing notification subscriptions, allowing you to enable or disable certain channels or categories of messages as needed.

If you voluntarily disable certain notifications or permissions to receive information, you may not claim on that basis that the notices or information did not take effect against you.
