充值与退款政策
生效日期：2026 年 10 月 30 日
要点
- 余额以美元计价，用于调用 BoomBit API，付款由 Stripe 安全处理。
- 充值成功后 24 小时内，可申请退还该笔充值中未使用的付费额度。
- 退款核算先扣除赠送额度，并收取 5.5% 的退款手续费（最低 0.80 美元）。
- 退款请发邮件至 service@boombit.online，由人工审核处理。
1. 充值
- BoomBit 账户余额以美元（USD）计价，按实际调用量扣费，各模型价格以官网公示为准。
- 在线充值通过 Stripe 完成，支持银行卡、Link、支付宝、微信支付等方式。BoomBit 不会接触或保存您的银行卡信息。
- 收款页可能以您所在地的货币显示金额，换算汇率由 Stripe 提供，最终以美元结算；发卡行或支付机构可能另收货币转换费用，该费用不在退款范围内。
- 付款成功后额度通常在几秒内到账。如长时间未到账，请在充值页「订单」中查看状态，或联系我们。
2. 赠送额度
- 单笔充值达到一定金额可获赠额度，具体以充值页显示为准。
- 赠送额度与付费额度一同计入余额、一同使用，但赠送额度不可退款、不可提现、不可转让。
3. 退款条件
- 仅可在充值成功后 24 小时内申请退款，超过 24 小时的充值不予退款。
- 仅退还该笔充值中尚未使用的付费额度。核算时先从可退额度中扣除该笔充值获赠的赠送额度。
- 每笔退款收取退款金额 5.5% 的手续费，最低 0.80 美元，用于覆盖支付通道成本。可退金额不足以支付手续费时，无法退款。
- 兑换码兑换的额度、活动赠送的额度不支持退款。
- 如因系统错误造成重复扣款或扣款后未到账，我们核实后全额退还对应款项，不受 24 小时限制，也不收取手续费。
示例：支付 $50，到账 $53（含赠送 $3），之后已使用 $10。
该笔充值剩余 $53 − $10 = $43，扣除赠送额度后可退 $43 − $3 = $40；
手续费 $40 × 5.5% = $2.20（高于最低 $0.80），实际退款 $40 − $2.20 = $37.80，同时从账户余额中扣回 $43。
4. 如何申请
- 在充值成功后 24 小时内发邮件至 service@boombit.online，注明账户用户名、订单号（以
bb_ 开头，可在充值页「订单」中复制）和退款原因。
- 我们通常在 3 个工作日内审核并回复。审核通过后，款项原路退回至付款账户；到账时间取决于银行或支付机构，一般为 5–10 个工作日。
- 退款完成后，对应额度将从账户余额中扣除。
5. 争议与拒付
如对扣款有疑问，请先联系我们，我们会尽快处理。若在未联系我们的情况下向发卡行发起拒付，我们可能在争议处理期间暂停相关账户的使用。
6. 政策更新
我们可能根据业务需要更新本政策，更新后的版本自公布之日起生效；更新前已完成的充值按充值当时的政策处理。
Top-up & Refund Policy
Effective: October 30, 2026
Key points
- Your balance is in US dollars and is used for BoomBit API usage. Payments are processed securely by Stripe.
- Within 24 hours of a successful top-up, you can request a refund of the unused paid credits from that top-up.
- Bonus credits are deducted first, and a 5.5% refund fee applies (minimum $0.80).
- To request a refund, email service@boombit.online. Requests are reviewed manually.
1. Top-ups
- BoomBit balances are denominated in US dollars (USD) and are charged per actual usage at the model prices published on our website.
- Online top-ups are processed by Stripe and support cards, Link, Alipay, WeChat Pay and more. BoomBit never sees or stores your card details.
- The checkout page may show the amount in your local currency using an exchange rate provided by Stripe; the payment settles in USD. Any currency-conversion fees charged by your bank or payment provider are not refundable.
- Credits usually arrive within seconds of payment. If they don’t, check the order status under Orders on the top-up page, or contact us.
2. Bonus credits
- Top-ups above certain amounts earn bonus credits, as shown on the top-up page.
- Bonus credits are added to and spent from the same balance as paid credits, but they cannot be refunded, withdrawn or transferred.
3. Refund eligibility
- Refunds can only be requested within 24 hours of a successful top-up. Top-ups older than 24 hours are not refundable.
- Only the unused paid credits from that top-up are refundable. The bonus credits received with that top-up are deducted from the refundable amount first.
- Each refund carries a fee of 5.5% of the refunded amount, with a minimum of $0.80, to cover payment processing costs. If the refundable amount does not exceed the fee, no refund can be issued.
- Credits from redemption codes or promotions are not refundable.
- If a system error causes a duplicate charge, or a payment is taken but credits are not added, we will refund the affected amount in full after verification, regardless of the 24-hour window and without a fee.
Example: you pay $50 and receive $53 (including a $3 bonus), then use $10.
Remaining from that top-up: $53 − $10 = $43; minus the bonus, refundable: $43 − $3 = $40.
Fee: $40 × 5.5% = $2.20 (above the $0.80 minimum), so you receive $40 − $2.20 = $37.80, and $43 is deducted from your balance.
4. How to request a refund
- Within 24 hours of the top-up, email service@boombit.online with your username, the order number (starting with
bb_, copyable from Orders on the top-up page) and the reason.
- We usually review and reply within 3 business days. Approved refunds go back to the original payment method; arrival time depends on your bank or payment provider, typically 5–10 business days.
- Once the refund is issued, the corresponding credits are deducted from your balance.
5. Disputes and chargebacks
If you have a question about a charge, please contact us first and we’ll resolve it promptly. If a chargeback is filed without contacting us, we may suspend the related account while the dispute is reviewed.
6. Changes to this policy
We may update this policy as our service evolves. Updates take effect when published; top-ups completed earlier are handled under the policy in effect at the time of the top-up.
