Yinso AI Credits and Pro Membership Terms

This update introduces automatic renewal for Monthly and Annual Pro Plans and explains recurring charges, cancellation and resumption, plan upgrades and downgrades, failed payments, subscriptions purchased while an existing Pro term is still active, and Lifetime Plan purchases made during a subscription. Quarterly Plans are currently unavailable and are not covered by this version of the Terms.

These Yinso AI Credits and Pro Membership Terms (the "Terms") form part of the Yinso AI Terms of Service. If these Terms conflict with the Terms of Service or any plan-specific terms clearly disclosed to you at checkout, the plan-specific terms applicable to your purchase and the Terms of Service will govern to the extent of the conflict. Nothing in these Terms limits any non-waivable rights available to you under applicable law.

1. Definitions

Credits:

Virtual service units used within Yinso AI to access AI generation, processing, and other compute-intensive features.

Pro Membership or Pro Plan ("Pro"):

A paid Yinso AI plan. Its price, duration, billing method, and included benefits are disclosed at checkout.

Post-Expiry Retention Period:

A limited period after Pro expires during which certain benefits, such as Subscription Credits or cloud-based access to Generated Content, may be unavailable but retained. Eligible benefits may be restored if you renew during this period.

Generated Content:

Music, audio, stems, and other outputs generated or processed through Yinso AI.

Generation Completion Time:

The time at which Yinso AI records a generation task as successfully completed, rather than the time at which you submit the task.

Auto-Renewing Subscription:

A Pro Plan that renews automatically at the end of each Billing Period and charges your selected payment method until you cancel. Monthly and Annual Plans are Auto-Renewing Subscriptions.

Billing Period:

The service period covered by each successful subscription charge. A Monthly Plan covers one month and an Annual Plan covers twelve months, beginning on the date the charge succeeds. Your Current Billing Period is the most recent paid Billing Period that has not yet ended.

Lifetime Plan:

A one-time-purchase Pro Plan that does not expire or renew automatically. A Lifetime Plan is not an Auto-Renewing Subscription.

Plan Change:

A change made while an Auto-Renewing Subscription is active to a different Billing Period or Credit tier. A Plan Change may be an Upgrade or a Downgrade, as described in Section 6.7.

2. What Are Credits?

• Credits are virtual service units used to access AI generation and processing services within Yinso AI.
• Credits have no cash value and cannot be withdrawn, transferred, exchanged for cash, used as legal tender, or applied against a monetary debt.
• Users on the Free Plan may purchase and use Credits, subject to any features that are available only through Pro.
• Credits are not cryptocurrency, electronic money, or a bank deposit.

3. Credit Types and Expiration

The availability and expiration of Credits depend on how they were obtained. Your Credits page will show each Credit type, balance, availability, expiration date, and permitted uses.

The expiration and allocation rules for Promotional Credits may vary by campaign, provided that the applicable rule is clearly disclosed before you claim or use the offer.

Credit expiration rules are intended to manage service capacity, generation costs, fair use, fraud, and abnormal resource accumulation. Expiration does not apply where prohibited by applicable law or the rules of the platform through which the Credits were purchased.

4. Credit Charges

• Credits may be used for music generation, stem separation, and other AI generation or processing features.
• The number of Credits required for a feature will be displayed before you submit the applicable task.
• Each generation request costs 10 Credits and produces two Generated Tracks.
• You cannot submit a task unless your available Credit balance is at least equal to the number of Credits displayed for that task.
• Unless otherwise disclosed, Yinso AI deducts Credits with the earliest expiration date first.
• If a price or Credit charge is displayed incorrectly because of an obvious technical error, Yinso AI may correct the error before the task is submitted. Charges already confirmed and completed will be handled in accordance with applicable law.

5. Credits and Pro-Only Features

• Credits are used to access generation and processing capacity. Some features may also require an active Pro plan, such as priority processing or specified advanced features.
• Having sufficient Credits does not give you access to a feature identified as Pro-only.
• If a feature requires Pro, you may subscribe to Pro or continue using an available Free feature.
• Pro requirements and material feature limitations will be disclosed before purchase or use.

6. Pro Terms

6.1 What Is Pro?

Pro is a paid Yinso AI plan that may include:

• higher-priority or faster generation;
• additional or more predictable generation capacity, including Subscription Credits;
• specified Pro-only features; and
• expanded contractual permissions for Generated Content, including commercial use as described in Section 7.

The specific benefits included in a Pro plan are those disclosed at checkout.

6.2 Plan Term and Activation

Available plan terms, prices, and benefits are disclosed at checkout. Pro is offered as a Monthly or Annual Auto-Renewing Subscription, or as a Lifetime Plan.

Monthly and Annual Plans are clearly identified at checkout as auto-renewing. We will enable automatic renewal only after you affirmatively select the automatic-renewal option and confirm your purchase. By completing the initial payment after opting in, you expressly authorize the recurring charges described in Section 6.5. If you do not opt in, we will not activate an Auto-Renewing Subscription or charge you for one.

A Lifetime Plan is paid for once, takes effect when payment succeeds, does not expire, and does not generate renewal charges. Sections 6.5 through 6.10 do not apply to a Lifetime Plan to the extent they address renewal, cancellation, Plan Changes, or failed recurring payments.

The price shown for each Billing Period is the amount you will be charged. Any per-month equivalent or savings comparison shown at checkout is illustrative only; the amount shown on the payment confirmation screen is the amount payable.

Pro benefits generally begin after payment succeeds and the plan is activated. If payment succeeds but your benefits do not appear, contact Yinso AI Support as described in Section 12.

6.3 Allocation of Subscription Credits

Monthly Plan:

The full Credit allocation for each Billing Period is issued after that period's charge succeeds.

Annual Plan:

The Credit allocation for each Billing Period is issued in twelve monthly installments. The first installment is issued on the date the annual charge succeeds, and the remaining installments are issued monthly on the corresponding calendar date.

If a later month does not contain the corresponding calendar date, that month's installment is issued on the last day of the month. Allocation is complete when the Credits appear in your account. A delay caused by maintenance, network conditions, or another technical issue does not reduce the total Credit allocation for the applicable Billing Period.

When you Upgrade, we issue the difference between the old and new plan's applicable Credit allocation on the date the Upgrade takes effect. When you Downgrade, Credits already issued for the Current Billing Period are not removed; the new Credit allocation begins with the next Billing Period. A Plan Change does not alter the expiration rules for Credits already issued.

6.4 Expiration and the Post-Expiry Retention Period

When Pro expires:

• unused Subscription Credits may become unavailable and enter the Post-Expiry Retention Period;
• Pro-only features stop unless otherwise disclosed;
• access to, downloading of, or cloud storage for Generated Content may change as described in Section 7; and
• Purchased Credits remain available and do not enter the Post-Expiry Retention Period.

During the Post-Expiry Retention Period, Yinso AI will not delete your Generated Content solely because Pro has expired, but cloud access or downloading may be limited. The duration of this period and the applicable access consequences are shown in your account or plan terms.

If you cancel an Auto-Renewing Subscription, any unused Subscription Credits expire at the end of the Current Billing Period and do not enter the Post-Expiry Retention Period. The Post-Expiry Retention Period applies only when Pro expires for a reason other than your voluntary cancellation, such as termination after a failed renewal payment under Section 6.10.

6.5 Renewal and Automatic Billing

• If you renew during the Post-Expiry Retention Period, eligible Subscription Credits and related benefits will be restored in accordance with the applicable plan terms.
• Renewal does not retroactively change the permissions applicable to content generated while you were using the Free Plan.
• Automatic renewal is activated only after you affirmatively opt in and confirm your purchase.
• At the beginning of each Billing Period, the payment method linked to your subscription will be charged the plan price disclosed when you subscribed, plus any applicable taxes, until you cancel.
• Before purchase, we show the amount charged each period, the Billing Period, and the automatic-renewal terms. After purchase, you can view your current plan, Current Billing Period, and next billing date on the Membership page.
• We will send a renewal reminder by email or in-app message at least seven days before each automatic renewal charge. This reminder applies to both Monthly and Annual Plans and will include the charge amount, Billing Period, and cancellation instructions.

Price changes apply to new purchases immediately. For an existing Auto-Renewing Subscription, a price increase will take effect no earlier than the next Billing Period after any notice, consent, or other procedure required by applicable law or the relevant billing provider. You may cancel before the new price takes effect.

Deleting the app or ceasing to use Yinso AI does not cancel an active subscription. If you subscribed through Apple, Google Play, or another third-party platform, you may need to manage or cancel the subscription through that platform.

6.6 Cancelling and Resuming an Auto-Renewing Subscription

You may cancel at any time from the Membership page by selecting Manage and then Cancel Subscription; you do not need to contact Support. Cancellation takes effect at the end of the Current Billing Period. You will not be charged for another Billing Period, and your Pro benefits remain available through the end of the Current Billing Period.

At the end of the Current Billing Period, any unused Subscription Credits expire and will not be retained or restored. Purchased Credits are not affected.

You may resume your subscription at any time before the Current Billing Period ends. If you resume, automatic renewal continues under the same plan.

6.7 Upgrades and Downgrades

While an Auto-Renewing Subscription is active, you may switch to a different Billing Period, such as from Monthly to Annual, or to a different Credit tier within the same Billing Period.

Upgrade:

A Plan Change to a plan with a higher recurring price. An Upgrade takes effect immediately. We calculate and charge a prorated price difference based on the remaining days in the Current Billing Period. A new Billing Period and billing date begin on the date the Upgrade takes effect.

Downgrade:

A Plan Change to a plan with a lower recurring price. A Downgrade takes effect at the end of the Current Billing Period. We do not refund the current period, and the new price and Credit allocation apply beginning with the next Billing Period.

The price adjustment and effective date shown on the billing provider's confirmation screen control your Plan Change.

6.8 Starting a Subscription During an Existing Fixed-Term Pro Plan

If you start an Auto-Renewing Subscription while a previously purchased, non-renewing fixed-term Pro Plan is still active, the first subscription charge is made immediately. Your existing Pro expiration date is extended by one Billing Period, and Subscription Credits are issued under Section 6.3. Your next billing date will be the extended expiration date.

6.9 Purchasing a Lifetime Plan During a Subscription

If you purchase a Lifetime Plan while an Auto-Renewing Subscription is active, the Lifetime Plan takes effect as soon as payment succeeds. Your existing subscription will be set to end at the close of the Current Billing Period and will not renew. The unused portion of the Current Billing Period is not refundable.

Once a Lifetime Plan is active, you cannot start an Auto-Renewing Subscription.

6.10 Failed Renewal Payments

If a renewal charge fails, we may retry the payment more than once during the following seven days. Your Pro benefits remain active during this retry period. The Membership page will show the failed-payment status, and you may update your payment method.

If payment still has not succeeded when the retry period ends, the Auto-Renewing Subscription terminates. Pro expires at the end of the Current Billing Period, after which Section 6.4 applies.

7. Generated Content and Commercial Use

AI-generated music and related rights are treated differently across jurisdictions and continue to evolve. This section sets out the contractual permissions between you and Yinso AI. It does not guarantee that any Generated Content qualifies for copyright, neighboring-right, or other intellectual-property protection in every jurisdiction.

7.1 Content Generated on the Free Plan

As between you and Yinso AI:

• Yinso AI does not represent or warrant that Generated Content created on the Free Plan qualifies for copyright or neighboring-right protection, or that any such rights legally belong to a particular party.
• Subject to these Terms and the Yinso AI Terms of Service, Yinso AI permits you to use such Generated Content for personal, non-commercial purposes, including personal listening, learning, and non-commercial sharing.

Unless Yinso AI expressly states otherwise, Free Generated Content may not be:

• used in paid advertising, commercial client work, commercial releases, sales, or monetized distribution;
• resold or packaged for resale as content or production material; or
• offered for a fee where the Generated Content, or a substantially substitutable version of it, is the primary item of value.

7.2 Content Generated While Pro Is Active

Subject to your compliance with these Terms, the Yinso AI Terms of Service, and applicable law, Yinso AI grants you, as between you and Yinso AI, an exclusive and irrevocable permission to use Generated Content created while Pro is active, including for commercial purposes. Permitted uses may include copying, publishing, distributing, publicly presenting, displaying, adapting, and creating derivative works to the extent reasonably necessary for your intended use.

This exclusivity applies only to the contractual relationship between you and Yinso AI. Subject to your compliance with these Terms, Yinso AI will not knowingly grant a third party a conflicting license to the same specific Generated Content. However:

• Yinso AI may store, process, transmit, display, distribute, recommend, moderate, investigate, and preserve Generated Content as reasonably necessary to operate the service, enforce these Terms, address complaints, resolve disputes, comply with law, and protect legal rights;
• AI systems may generate identical or similar content for different users;
• Yinso AI does not guarantee that Generated Content is unique, original, non-infringing, or eligible for intellectual-property protection; and
• this section does not grant you rights in third-party materials included in your prompts, uploads, lyrics, samples, recordings, voices, names, likenesses, trademarks, or other inputs.

If you upload, adapt, cover, imitate, or otherwise use third-party music, recordings, lyrics, voices, or other protected material, you are responsible for obtaining all permissions necessary for your generation and intended use. You must not publish, distribute, monetize, or publicly perform the resulting content unless you have the required rights.

If a claim, complaint, or dispute arises from your inputs, edits, use, or distribution of Generated Content, you are responsible for your conduct and must reasonably cooperate with the review process. Yinso AI may restrict access, make content private, remove content, disable links, or suspend relevant features where reasonably necessary to address alleged infringement, unlawful content, a violation of these Terms, or a legal requirement.

When Pro expires, the permissions granted under this Section 7.2 for content generated while Pro was active continue, subject to these Terms, the Yinso AI Terms of Service, third-party rights, and applicable law.

7.3 No Retroactive Upgrade

Subscribing to Pro does not retroactively change the permissions that apply to content generated while you were using the Free Plan.

7.4 Your Responsibilities

• You must ensure that your prompts, uploads, materials, instructions, and intended uses are lawful and do not infringe or violate any third-party rights.
• You are responsible for claims or disputes arising from your inputs, modifications, distribution, or use.
• Where legally permitted and reasonably available, Yinso AI may provide relevant order or generation records to assist with a legitimate dispute or rights inquiry.

8. Credit Restorations and Monetary Refunds

• A Credit Restoration returns Credits previously deducted from your Yinso AI account.
• A Monetary Refund returns an eligible payment through the original payment method or as otherwise required by the applicable billing provider or law.
• A Credit Restoration is not a Monetary Refund.

9. Credit Restoration and Refund Policy

9.1 Credit Restorations

9.1.1 Eligible Cases

Credits deducted for a task will normally be restored if the task is not successfully completed and Yinso AI confirms one of the following:

Technical failure:

A system error, timeout, or similar technical issue causes the task to fail.

Safety rejection:

The task cannot be completed because an automated content-safety control blocks it before successful generation.

Credits are normally not restored merely because:

• a generation completes successfully but you do not like the creative result; or
• you voluntarily stop, abandon, or choose not to use a successfully completed result.

If a task produces partial content that is accessible or downloadable, Yinso AI may provide a full or partial Credit Restoration based on the amount of usable output delivered. Yinso AI may decline repeated restoration requests arising from intentional or abusive attempts to submit content prohibited by the Yinso AI Terms of Service.

9.1.2 Method and Timing

Automatic restoration:

Eligible Credits are normally restored automatically. Where technically possible, Yinso AI will restore the original Credit type and remaining validity period. Otherwise, equivalent Service Credits may be issued with a validity period no shorter than the remaining validity of the deducted Credits.

Manual review:

If Credits were deducted but not restored after an eligible failure, contact Yinso AI Support and provide your account identifier, approximate task time, and relevant task or order number.

Service Credits may be used together with other Credits. Credits with the earliest expiration date are generally used first.

9.2 Monetary Refunds

Credit purchases and Pro are digital services or virtual benefits. Once delivered or used, they are generally non-refundable, except where a refund is required by applicable law or the rules of Apple, Google Play, another app store, or the applicable payment provider.

A Billing Period that has already begun is non-refundable, regardless of how many Pro benefits or Subscription Credits you use during that period. Cancelling an Auto-Renewing Subscription stops future renewal charges only. Prorated Upgrade charges and the unused portion of a subscription after you purchase a Lifetime Plan are also non-refundable, except where applicable law or the billing provider's rules require otherwise.

You may request review of a refund where:

• payment succeeded but the purchased Credits or Pro benefits were not delivered;
• you were charged more than once for the same purchase;
• a technical failure prevented Yinso AI from providing the purchased service and the service cannot reasonably be restored or re-delivered; or
• applicable law or the billing provider's rules provide an additional refund right.

If you purchased through Apple, Google Play, or another third-party platform, the refund request may need to be submitted directly to that platform.

To request a refund from Yinso AI, submit a support request and include your account identifier, order or transaction number, proof of payment, and a description of the issue. Do not send full payment-card numbers, passwords, government identification numbers, or unrelated sensitive information. Redact such information from screenshots.

Approved refunds are returned through the original payment method where available. Processing and settlement times depend on the payment provider.

10. Abuse Prevention and Enforcement

Yinso AI may take reasonable and proportionate action if you engage in fraud, automated abuse, unauthorized scripting, excessive or coordinated misuse, attacks on the service, infringement, or the creation or distribution of unlawful content.

Actions may include:

• limiting features or generation capacity;
• temporarily restricting or freezing Credits while suspected fraud or abuse is investigated;
• suspending or terminating Pro;
• suspending or closing an account;
• removing or restricting access to content; and
• pursuing remedies available under applicable law.

Where reasonably practicable and legally permitted, Yinso AI will provide notice of material enforcement action and a method to contact Support. Immediate action may be taken where necessary to protect users, the service, third-party rights, or legal compliance.

11. Changes to These Terms

• Wylynk (HK) Limited may update these Terms to reflect product changes, service costs, security needs, platform requirements, or applicable law.
• The updated version will state its effective date.
• Material changes will be notified through the service, by email, or through another reasonable channel before they take effect where required by law.
• Changes will not retroactively remove commercial-use permissions already granted for eligible Generated Content or reduce Purchased Credits already acquired, except where required by law or necessary to address fraud, abuse, or a legal violation.
• Where legally permitted, continued use after the effective date of an update constitutes acceptance of the updated Terms. If applicable law requires express consent, Yinso AI will request it.
