This agreement covers buying digital works, per-call services, call packs, Ink, Cash balance and hardware on Encore Aria. It forms part of the Terms of Use. The "Purchase Agreement" mentioned on the site refers to this document.
Please read the parts in bold before you pay, especially: downloads and per-call services cannot be cancelled once supplied, one refund per order, coupons are not returned, successful calls are not refundable, call packs cannot be refunded on request, Cash balance cannot be withdrawn, purchased Ink is generally non-refundable, 7-day no-questions returns for hardware depend on the product page, and how we handle refund abuse. None of this limits the mandatory consumer rights you have under the law of the country where you live (see Section 13).
1. Who sells what
1.1 Works, per-call services and hardware in the Catalogue are listed and supplied by Authors. The Author is the seller and is responsible for the description, quality, delivery and after-sales service. We run the platform: we show listing information, process payments, keep order records, help with after-sales issues and disputes, and meet the duties the law places on us as a platform. Where a listing clearly says it is offered by Encore Aria itself, we are the seller. Authors may be individuals selling in a personal capacity or businesses. If an Author is not acting as a trader, some consumer protection rules that apply to purchases from traders may not apply to your contract with that Author. If you are unsure, ask the Author before you buy.
1.2 Before you pay, the page shows what you are buying, who is selling it, the price, how it is delivered, the licence and the after-sales terms. Your order records the description, price and licence at the time you bought. Later edits to the listing do not change an order you have already placed.
1.3 "Refunded to the original payment method" means back to whatever you paid with: Alipay, WeChat Pay, bank card, or Cash balance. Once a refund is issued, how long it takes to arrive depends on the payment provider; we can help you check its progress.
2. Payment and orders
2.1 We accept Alipay, WeChat Pay, international bank cards (processed by Creem in US dollars, for digital works) and Cash balance. Which methods you can use for a particular item is shown at checkout. Cash balance cannot be used for hardware or Ink; call packs can only be bought with Cash balance; Ink and Cash balance can only be topped up with Alipay or WeChat Pay.
2.2 Prices are set in Chinese yuan (CNY). If you choose US dollars as your display currency, USD amounts are shown for your convenience. If you pay by card in US dollars, you are charged the USD amount shown at checkout. Your bank may apply its own fees or exchange rates. Card refunds are processed manually by us through Creem, and timing depends on your card issuer.
2.3 Unpaid orders are cancelled automatically after 30 minutes.
2.4 If you check out several items from your cart together, each item is still a separate sub-order, delivered and supported by its own seller.
3. Digital works (downloads)
3.1 What you get. You get the files, version and documentation listed on the work page. Whether source code, future updates or support are included is stated on the work page.
3.2 Licence. You receive a licence from the Author to use the work. You do not receive the copyright. The scope is as stated on the work page. If the page says nothing more specific, you may use and modify the work for your own or your organisation's internal purposes, but you may not resell, redistribute or publicly share the files, or offer the files themselves as a product or service to others. Your display name is added to the downloaded file name to discourage piracy.
3.3 If a work is unlisted. If an Author unlists a work or leaves Encore Aria, the licence you lawfully obtained continues. If a work is removed for infringement or illegality, you should stop using the affected parts, and we will help you seek a remedy from the Author.
3.4 Immediate access; no cancellation for change of mind. Downloadable works are made available immediately after payment. The first time you buy a downloadable work, you confirm on the purchase page (the box is not pre-ticked) that you want immediate access and that you lose any right to cancel or withdraw from the purchase once the work is made available. Every work page and checkout page after that reminds you of this. This does not affect your right to appeal under Section 3.5.
3.5 Appeals and refunds.
- You can appeal within 7 days of payment from the order's delivery page (you can follow its progress under After-sales & appeals). Tell us why, for example: the work is seriously misdescribed, the files are corrupt or cannot be downloaded, the core functions do not work at all, or the work appears to infringe someone else's rights.
- "Usable but not great" or simply not liking it are not grounds for a refund.
- If we approve your appeal, you get a full refund to the original payment method, your access to the work is frozen, and you must delete any downloaded files and stop using them.
- Partial refunds are not available, and each order can only be refunded once.
- For items bought together through the cart, email aiencore@stillhappy.cn to appeal.
- Duplicate or erroneous charges, and other cases where the law requires a refund, are not subject to the 7-day limit. If you discover a serious problem or infringement after 7 days, email us and we will help in line with applicable law.
4. Per-call services
4.1 Pricing. You pay for each successful call. The work page shows the price before you run it. If a work has tiered pricing, your price tier depends on how many successful calls you have made on that work.
4.2 How to pay. You can pay with Cash balance, a call pack or by scanning a payment code. If the work offers free trials, you can also use your trial calls.
4.3 No cancellation once performed. A per-call service runs immediately after payment and is complete once the call has run; it cannot then be cancelled for a change of mind. The work page reminds you of this.
4.4 Failed calls are refunded automatically. You don't need to ask:
- paid with Cash balance: refunded to your Cash balance;
- paid with a call pack: the call is added back;
- paid by scanning a payment code: refunded to the original payment method;
- free trial: the trial call is restored.
If a failure can be retried, the system retries automatically. Each call is attempted at most 3 times, and retries are never charged twice.
4.5 Successful calls. Once a call succeeds, it is not refundable in the normal way. AI output may be inaccurate or not to your taste, so please read the work page and examples before you run it. If you think a result is abnormal (for example, it clearly does not do what the work page promises), email us or send feedback from Account & Support with the call number. If we confirm the problem, we can refund you.
4.6 Call content is deleted automatically. To protect your privacy, inputs are deleted after 7 days and outputs after 30 days, so save any results you need. You can also delete them earlier in Call history.
4.7 Calls from your devices. Calls you start from a command-line tool or AI agent follow the same rules as calls on the website. Keep device authorisations secure and revoke them under Call settings when you no longer need them.
5. Call packs
5.1 A call pack is a prepaid set of calls for a per-call work. Call packs can only be bought with Cash balance.
5.2 Call packs do not expire.
5.3 You cannot ask for a refund of a call pack after buying it. If the work is unlisted, the system automatically converts your unused calls into money, in proportion to the calls remaining, and refunds it to your Cash balance (not to the original payment method).
5.4 If the Author later changes the price, the number of calls in a pack you already bought does not change.
6. Cash balance
6.1 Cash balance is money in Chinese yuan that you pre-load onto Encore Aria. It earns no interest and does not expire. Each top-up must be at least CNY 10, and you can top up no more than CNY 500 per day.
6.2 You can spend Cash balance on digital works, per-call services and call packs, but not on hardware or Ink. Cash balance and Ink are separate and cannot be exchanged.
6.3 Cash balance cannot be withdrawn as cash or transferred to anyone else.
6.4 To get unused Cash balance back, email aiencore@stillhappy.cn from your registered email address. We will check your top-up records and balance, return it to the original payment method manually, and deduct the refunded amount from your Cash balance. Amounts already spent are not refunded.
6.5 Before closing your account, we will remind you about any remaining Cash balance. Closing your account, account restrictions or our shutting down the service do not wipe out Cash balance that must be refunded to you by law.
7. Ink
7.1 Ink is an in-platform credit for AI interaction. 1 Ink = CNY 0.1. At the moment Ink can only be spent on having AI Personas comment. Ink is not money and earns no interest.
7.2 There are two kinds of Ink:
- purchased Ink, bought with Alipay or WeChat Pay, which never expires;
- granted Ink, which you receive for signing up, as a monthly allowance, for daily check-ins, from redemption codes or as event rewards, and which expires 30 days after you receive it. The current amounts are shown on the site.
7.3 Granted Ink is spent first (earliest expiry first), then purchased Ink.
7.4 Ink cannot be transferred, exchanged for cash or converted into Cash balance. Granted Ink is never refunded or exchanged for money.
7.5 Purchased Ink is generally non-refundable. The exceptions are below; email us if one applies:
- you were charged twice;
- a system fault caused a top-up or deduction error;
- we discontinue the Ink feature, in which case we refund unused purchased Ink;
- a minor bought Ink without a parent's or guardian's consent, in which case the guardian can apply for a refund with proof of guardianship, the payment record and an explanation (we will not refund where the guardian knew in advance or helped pay);
- any other case where the law requires a refund.
When we refund Ink, we deduct the refunded Ink from your account.
8. Hardware
8.1 Seller. Hardware is sold and shipped by Authors. The product page shows the condition (new, DIY kit or used), where it can be shipped (mainland China only; mainland China plus Hong Kong, Macao and Taiwan; or worldwide), shipping cost and warranty. Hardware cannot be bought with Cash balance or Ink.
8.2 International shipping. For shipments outside mainland China, import duties, taxes and customs charges may apply. Unless the product page says they are included, you may have to pay them when the goods are imported.
8.3 Shipping and confirming receipt. The seller should ship within the time promised on the product page and give you a tracking number. If you have not confirmed receipt 10 days after the item is shipped, receipt is confirmed automatically. If you have not received the item in that time, open an after-sales request on the order or contact us promptly.
8.4 After-sales options and time limits.
- Within 7 days of receiving the item, you can request a refund only, a return and refund, or an exchange from your hardware orders;
- before you receive the item, you can only request a refund only; if the item is already in transit, a refund-only request needs the seller's agreement;
- if a quality problem appears more than 7 days after you receive the item, message the seller on Encore Aria or email us, and it will be handled under applicable law and any warranty the seller offers.
8.5 7-day no-questions returns. Whether an item can be returned within 7 days without giving a reason depends on what its product page says. If the page says "7-day no-questions return", you can return it within 7 days of receipt as long as it is in resaleable condition; opening and trying the item reasonably to check it does not prevent a return. If the page says the item does not support this, you can still request after-sales service for quality problems, wrong or missing items, or items that do not match their description, and any statutory right to cancel under your local law still applies.
8.6 Return shipping. When the seller agrees to a return, the seller chooses who pays return shipping. Our default rule is that you pay return shipping for returns that are not due to a quality problem, and the seller pays shipping both ways for quality problems, wrong items, missing items or other seller faults.
8.7 Refunds. For a return and refund, the seller refunds you to the original payment method after receiving and checking the return. Items paid for together are refunded per sub-order.
8.8 Contacting the seller. Please contact the seller about after-sales issues through Encore Aria messages, not off-platform. If the seller does not respond or you cannot agree, ask for our help under After-sales & appeals or email us.
9. Open Calls
Open Calls let people post briefs, show information and talk. We do not handle any money for Open Call projects and we are not responsible for producing, accepting or guaranteeing them. The parties may sign their own contract covering deliverables, price, acceptance and intellectual property. If a resulting work is listed in the Catalogue, it is bought under the rules for digital works or per-call services above.
10. Coupons
10.1 Coupon conditions and expiry dates are shown where you get the coupon. Expired coupons cannot be used and coupons cannot be exchanged for cash.
10.2 If an order paid partly with a coupon is refunded, only the amount you actually paid is refunded. The coupon is not returned.
11. After-sales requests and refunds
11.1 How to ask. Use the order page or After-sales & appeals, or email aiencore@stillhappy.cn. Include your order or call number, what went wrong and any screenshots or other evidence. We will not ask for personal information unrelated to your request.
11.2 What we do. We review your request based on the issue and the evidence, ask you or the seller for more information if needed, and keep you updated.
11.3 Where refunds go. Approved refunds go to the original payment method (see Section 1.3). The exception is a call pack refunded because its work was unlisted, which goes to your Cash balance (see Section 5.3).
11.4 Abuse. If we find stolen payments, repeated refund claims, fraudulent chargebacks, multiple accounts used to collect rewards, or continued use of a work after a refund, we may investigate, suspend the related entitlements and new purchases, and recover what was improperly obtained as the law allows. You are responsible for direct losses this causes us, such as chargeback fees charged by payment providers. Using your genuine refund and after-sales rights is never treated as abuse.
11.5 Our decision is not final. Our handling of an appeal is not arbitration or a court decision. If you are unhappy with it, you can still complain to a consumer authority or go to court. Arrangements between us and Authors over settlement and recovery do not affect your right to a refund you are legally owed.
12. Updates to works and existing orders
12.1 When an Author changes a work's description, price, licence or files, the change only applies to new orders. Your existing order keeps the content and licence from when you bought it.
12.2 When a new version of a work is released, whether you get it free is stated on the work page. If you need to buy the new version, your licence for the version you already bought is unaffected.
12.3 If an older version can no longer be provided because of illegality, infringement or a security risk, we may stop access to it and arrange a fix, replacement or refund as appropriate.
13. Your consumer rights
If you are a consumer, nothing in this agreement limits or excludes the rights you have under the mandatory consumer protection laws of the country where you live, such as statutory guarantees for goods and digital content, and remedies such as repair, replacement, price reduction or refund. Where this agreement is less favourable to you than those laws, the laws apply instead.
14. Liability and disputes
14.1 Our limits on liability are set out in Section 10 of the Terms of Use, changes in Section 13, and governing law and disputes in Section 12.
14.2 Disputes between you and an Author about a work or hardware you bought from them are subject to the jurisdiction decided by law.
