Refund Policy
Last updated: 7 October 2026 · Applies to all paid licenses of the Container Loading Calculator (container-calc.com)
In one sentence: if you are not satisfied with your purchase, we refund the unused part of your license period — the refund is calculated proportionally on the remaining days, not a flat fee.
1. How the refund is calculated
Refund = license price × remaining days ÷ total license days
- Remaining days = total license days − days already elapsed since your purchase date.
- The purchase date is the date of the payment confirmation email, not the date you first used the tool.
- Partial days are counted as whole elapsed days.
- Amounts are rounded down to the nearest cent.
2. Worked examples
| License | Refund requested | Elapsed / remaining | Refund amount |
| 6 months — US$12.99 | after 30 days | 30 / 180 days elapsed → 150 remaining | US$10.82 |
| 12 months — US$19.99 | after 60 days | 60 / 365 days elapsed → 305 remaining | US$16.70 |
| 12 months — US$19.99 | after 300 days | 300 / 365 days elapsed → 65 remaining | US$3.56 |
| Domestic CNY plans | any time | Same principle, pro-rated on the remaining days of the plan you bought. |
3. How to request a refund
- Email [email protected] from the address used at checkout, or from any address — just include your order number (it is in your payment receipt) or the email address you paid with.
- Tell us briefly that you would like a refund under this policy. You do not have to explain why you are unsatisfied, but the reason helps us improve the tool.
- We confirm the calculation and issue the refund through our payment partner Lemon Squeezy (international payments) or through the domestic payment channel used at checkout.
- Once approved, the refund is returned to your original payment method. Card and PayPal refunds usually appear within 5–10 business days, depending on your bank or card issuer.
4. After the refund
- Your license key is deactivated when the refund is issued, and the site returns to the free trial limit.
- You may buy again later; a refunded purchase does not prevent a future purchase.
- Refunds are always returned to the original payment method. We cannot refund to a different card or account.
5. Costs that cannot be refunded
- Payment processing fees already charged by the payment provider are not refundable. Where they apply, they may be deducted from the refund amount — the worked examples above show the amount before any such deduction.
- Any third-party currency conversion or bank fee charged by your own bank is outside our control and cannot be refunded by us.
- Taxes collected at checkout are refunded together with the proportional refund where the payment provider supports it; the tax portion follows the provider's tax rules for your country.
6. Your statutory rights
Nothing in this policy limits any non-waivable consumer right you may have under the law of your country of residence. Where local law grants you a stronger right (for example a statutory cooling-off period for digital purchases), that right applies in addition to this policy. Because the license key is delivered immediately after payment, you may be asked to acknowledge that immediate delivery starts performance of the contract.
Abuse: we may decline a refund request where there is evidence of fraud, a reversed payment without contacting us first, or repeated buy-refund cycles on the same license. In that case the dispute is handled by the payment provider.

退款政策(中文)
一句话:对购买不满意可以申请退款,我们按剩余天数比例退还尚未使用的部分,而不是一刀切扣掉整笔费用。
计算公式:退款额 = 授权价格 × 剩余天数 ÷ 授权总天数。购买日期以支付成功邮件的时间为准(不是你第一次使用工具的日期);不足一天按整天计算;金额向下取整到分。
| 授权档位 | 申请时点 | 已用 / 剩余 | 退款金额 |
| 6 个月 — US$12.99 | 第 30 天 | 已用 30 / 180 天 → 剩 150 天 | 约 US$10.82 |
| 12 个月 — US$19.99 | 第 60 天 | 已用 60 / 365 天 → 剩 305 天 | 约 US$16.70 |
| 境内档位(人民币) | 任意时点 | 同一原则,按所购档位的剩余天数折算。 |
怎么申请:发邮件到 [email protected],附上订单号(在支付收据里)或付款时用的邮箱即可,不需要说明理由。我们核算后通过支付渠道原路退回,卡与 PayPal 通常 5–10 个工作日到账。
退款之后:授权码随即失效,网站回到免费试用额度;以后仍可再次购买。退款一律原路退回,无法换卡或换账户。
不予退还的部分:支付通道已产生的手续费、以及你所在银行收取的货币转换费或手续费,我们不承担也不退还;结账时收取的税费按支付服务商的规则随同退还。本政策不限制你所在国家法律赋予你的强制性消费者权利,若当地法律给你更强的权利(例如法定冷静期),该权利同样适用。
