Refund Policy
Rules for subscriptions, Usage Credit Pack purchases, cancellations, refunds, chargebacks, and disputes
1. Scope
This Refund Policy applies to monetary refunds for subscriptions, Usage Credit Packs, and related digital services purchased through Didymoi / Didymoi Cloud. A refund returns an eligible order amount to the original payment method. Credit restorations after failed API calls or connected Didymoi application tasks are service corrections and do not constitute monetary refunds.
2. General principles
Usage Credit Packs are one-time purchases and do not renew automatically. Credits already used, expired, converted into service outputs, or consumed because of account-security issues under the user's control are generally not eligible for discretionary refunds.
This policy does not limit any mandatory refund, withdrawal, quality, or dispute rights you may have under applicable consumer protection laws.
If you expressly request immediate issuance and performance of the digital service at checkout, you acknowledge that your statutory withdrawal right may end once performance begins, to the extent permitted by applicable law. Rights relating to defects, non-delivery, and other non-waivable remedies remain unaffected.
3. Subscription cancellation and refunds
Canceling a subscription and requesting a refund are different actions. Cancellation prevents future renewals and normally takes effect at the end of the current billing period. Unless applicable law, checkout, or the collecting party's terms provide otherwise, cancellation does not automatically refund unused time in the current period.
Subscriptions are charged immediately at checkout. Refund eligibility is determined under checkout disclosures, the collecting party's buyer terms, this Policy, and applicable consumer-protection law.
You may request a refund or other appropriate remedy for duplicate charges, unauthorized transactions, non-delivery, persistent material technical defects, an incorrect amount, or circumstances where law requires a remedy. Nothing in this Policy limits non-waivable consumer withdrawal, refund, or quality rights.
If a subscription charge is fully or partially refunded, charged back, or reversed, unused initial or subscription credits linked to that transaction may be revoked. If the account does not contain enough recoverable credits, we record the unrecovered amount without making the account balance negative.
4. Cases we may consider
We may consider payment refunds case by case, including duplicate payments, successful payment without issuance of Usage Credits, platform-confirmed technical failures, mistaken purchases where the credits have not been used, unauthorized transactions, abnormal transactions, or legally required refunds.
A request submitted through Didymoi's in-account refund flow is treated as a request for a full refund. Refund eligibility is determined by the seller identified at checkout under this Policy, applicable buyer terms, Usage Credit consumption, order status, channel rules, risk review, and applicable law. A payment provider may execute a refund, conduct risk review, or request additional verification within its role. If Paddle or another party is the seller, that seller handles the refund decision under its applicable terms.
5. Cases generally not eligible
Payment refunds are generally not available where Usage Credits have been fully or partially used, the credits have expired, the user violated the Terms of Service, account sharing or credential leakage caused usage, the refund mechanism is abused, or fraud or chargeback abuse is detected. This does not exclude platform-error or mandatory legal remedies.
6. Treatment of Usage Credits after a refund
For a partial refund, Usage Credits to revoke are generally calculated as the refund amount divided by the original order amount, multiplied by the credits granted, rounded up to a whole credit and capped at the credits granted for that order.
If a partial refund, chargeback, or dispute occurs, we may revoke, freeze, or adjust corresponding Usage Credits based on the refund amount, unused credits, and order status.
If there are insufficient recoverable credits in the account, the system records the unrecovered amount without creating a negative balance.
7. Payment-provider handling
For transactions completed through Paddle, the order process is conducted by the online reseller Paddle.com. The Paddle entity identified at checkout acts as the authorized reseller and Merchant of Record and is responsible within its role for payment collection, applicable sales taxes, billing, order support, and refund processing. Paddle's Buyer Terms (https://www.paddle.com/legal/buyer-terms) and Refund Policy (https://www.paddle.com/legal/refund-policy) also apply.
For a transaction processed through standard Stripe Payments where checkout does not identify Stripe or an affiliated service as the seller or Merchant of Record, Didymoi or another party identified at checkout determines refund eligibility, while Stripe and relevant financial institutions handle refund execution, risk review, and settlement within their respective roles. If checkout expressly identifies Stripe Managed Payments, a Stripe-affiliated Merchant of Record, or another Merchant of Record service, the seller and refund terms identified at checkout, in the order confirmation, and on the receipt apply.
For other transactions, responsibility for payment, taxes, receipts, invoices, refund decisions, and settlement timing may be divided among the seller, payment provider, bank, or payment method identified at checkout. The checkout page or receipt identifies the applicable parties and related terms.
Refund settlement times vary by payment method and follow the timing stated by the payment channel shown on the order.
8. How to request a refund
Use the refund option in your Didymoi account billing page, order receipt, or checkout page where available. For Paddle transactions, you may also use the View receipt or Manage subscription link in your receipt or visit https://paddle.net for buyer support. If you still cannot submit the request, email billing@didymoi.com with your account email, order ID, payment time, requested amount, refund reason, and relevant screenshots. We may request additional information to verify identity and transaction details.
We make reasonable efforts to provide an initial response within 3–5 business days. Actual review and processing time depends on the seller shown on the order, the payment provider, the bank, and the complexity of the dispute.
Approved refunds are generally returned to the original payment method; actual settlement time depends on the payment provider, bank, or other payment channel.
If you disagree with a refund decision, reply to billing@didymoi.com within 30 days to request a review and provide additional information. This process does not limit any rights to contact your payment provider or a consumer-protection authority.
1. 适用范围
本退款政策适用于通过 Didymoi / Didymoi Cloud 购买订阅、使用积分包及相关数字服务所产生的真实货币退款。退款是指将符合条件的订单款项退回原支付方式；API 调用或关联 Didymoi 应用任务失败后的计费纠错不属于本政策所称退款。
2. 基本原则
使用积分包属于一次性购买，不会自动续费。已经实际使用、过期、转化为服务结果或因用户账号安全问题被使用的积分，原则上不支持酌情退款。
本政策不限制适用消费者保护法律赋予你的强制性退款、撤回、质量保障或争议权利。
如果你在购买时明确要求立即发放积分并开始提供数字服务，你确认在服务开始履行后，法定撤回权可能在适用法律允许的范围内终止；质量问题、未交付及其他不可放弃的法定权利不受影响。
3. 订阅取消与退款
取消订阅与申请退款是不同操作。取消会阻止后续续费，并通常在当前计费周期结束时生效；除非适用法律、订单页面或收款方条款另有规定，取消本身不会自动退还当前周期未使用的时间。
订阅会在结账时立即扣款。退款资格按订单页面、收款方买方条款、本政策和适用消费者保护法律判断。
订阅发生重复扣款、未经授权交易、未交付、持续性重大技术缺陷、错误金额或法律要求的情形时，可以申请退款或其他适当补救。任何表述都不限制不可放弃的消费者撤回、退款或质量保障权利。
订阅款项被全额或部分退款、拒付或撤销时，与该交易关联的首次赠送积分或订阅积分可能按未使用数量回收。账户中可回收积分不足时，系统会记录未回收数量，但不会将账户余额扣为负数。
4. 可考虑退款的情况
我们可能在个案基础上考虑支付退款，包括重复付款、付款成功但积分未到账、平台确认的技术故障、误购且积分未使用、未经授权交易、异常交易或法律要求的退款场景。
用户通过 Didymoi 账号内退款入口提交的申请默认按全额退款申请处理。退款资格由结账页面列明的销售方根据本政策、适用买方条款、积分使用情况、订单状态、渠道规则、风险审查和适用法律确定。支付服务商可在其职责范围内执行退款、开展风险审查或要求补充验证；如 Paddle 或其他主体是交易销售方，则由该销售方按照其适用条款处理退款决定。
5. 通常不支持退款的情况
使用积分已经全部或部分使用、积分已过有效期、用户违反服务条款、账号共享或凭证泄露导致消耗、滥用退款机制、欺诈或拒付滥用等情况，通常不支持支付退款，但不排除平台错误或适用法律要求的例外。
6. 退款后的使用积分处理
部分退款需回收的使用积分通常按以下比例计算：退款金额 ÷ 原订单金额 × 订单发放积分，并按整数向上取整；累计回收积分不会超过该订单发放的积分。
如发生部分退款、拒付或争议，我们可能按退款金额、未使用积分和订单状态回收、冻结或调整相应使用积分。
如果账户中可回收积分不足，系统会记录未回收积分，但不会因此将账户积分扣为负数。
7. 支付服务商处理关系
对于通过 Paddle 完成的交易，订单流程由在线转售商 Paddle.com 提供。结账页面列明的 Paddle 实体作为授权转售商及 Merchant of Record，负责其职责范围内的收款、适用销售税、账单、订单支持和退款处理。该交易同时适用 Paddle 买方条款（https://www.paddle.com/legal/buyer-terms）和 Paddle 退款政策（https://www.paddle.com/legal/refund-policy）。
对于通过普通 Stripe Payments 完成且结账页面未将 Stripe 或其关联服务列为销售方或 Merchant of Record 的交易，Didymoi 或结账页面列明的其他主体负责判断退款资格，Stripe 及相关金融机构在其职责范围内处理退款执行、风控和资金结算。如果页面明确显示 Stripe Managed Payments、Stripe 关联的 Merchant of Record 或其他 Merchant of Record 服务，则以该页面、订单确认和收据列明的销售方及退款条款为准。
其他交易的付款、税费、收据、发票、退款责任和退款到账时间，可能由结账页面列明的销售方、支付服务商、银行或支付方式分别负责。订单页面或收据会展示适用主体及相关条款。
不同支付方式的退款到账时间可能不同，具体以订单所示支付渠道的说明为准。
8. 如何申请退款
请优先通过 Didymoi 账号的账单页面、订单收据或结账页面提供的退款入口申请。Paddle 交易也可通过收据中的 View receipt 或 Manage subscription 链接，或访问 https://paddle.net 请求支持。如仍无法提交，可发送邮件至 billing@didymoi.com，并提供账号邮箱、订单号、付款时间、退款金额、退款原因和必要截图。我们可能要求补充信息以验证身份和交易。
我们通常会在 3–5 个工作日内回复初步结果；实际审核和处理时间由订单所示销售方、支付服务商、银行及争议复杂程度决定。
批准的退款通常会原路退回原支付方式；实际到账时间取决于支付服务商、银行或其他支付渠道。
如不同意退款决定，你可以在收到结果后的 30 天内回复 billing@didymoi.com 申请复核并补充材料。该流程不限制你依法向支付机构或消费者保护机构寻求帮助。
