20cm.ai 订阅属于数字软件服务，由 20CM, LLC 运营。付款完成后，系统会立即为您的账户开通所购套餐，并分配存储空间、网络带宽和分析计算等资源。这些资源在套餐开通时即已分配和占用，因此付款完成后不支持退款，包括订阅期内未使用的时间。
20cm.ai subscriptions are digital software services operated by 20CM, LLC. As soon as a payment is completed, your plan is activated and the system allocates resources to your account, including data storage, network bandwidth and computing for analysis. Because these resources are provisioned and committed when the plan starts, payments cannot be refunded, including for any unused part of a billing period.
您可以随时取消订阅，取消后不再自动续费。已付费的使用期结束前，您仍可正常使用所购套餐。
You may cancel at any time to stop future renewals. Your plan remains available until the end of the period you have already paid for.
如发生重复扣款、扣款金额错误，或因我方系统原因无法使用已付费的套餐，请在付款后 7 天内通过 Support 页面联系我们。经核实的扣款错误，我们会予以更正。
If you were charged twice, charged an incorrect amount, or cannot access the plan you paid for because of a fault on our side, contact us through the Support page within 7 days of the payment. We will correct verified billing errors.
