Refund Policy

Last updated: October 2026

1. 7-Day Refunds

Within 7 days of your first subscription to any paid plan, you may request a full refund if you are not satisfied (provided there is no clear abuse, such as burning through quotas in a short burst).

2. Pro-Rata Refunds

After 7 days, used billing periods are non-refundable; unstarted full periods may be refunded pro-rata. Yearly plans are prorated by remaining full months; the exact amount follows the payment provider's settlement.

3. Non-Refundable Cases

Accounts suspended or terminated for Terms violations; orders from unofficial channels; repeated refund abuse.

4. How to Apply

Email ecjtu.zeng@gmail.com with your account email, plan, and order number (Paddle transaction ID or Alipay order number). We review within 7 business days and refund to the original payment method; Paddle orders follow Paddle's refund flow and timelines.

5. Cancelling

You can cancel auto-renewal anytime in account settings and keep access until the period ends. Cancellation is not a refund — file a separate request per section 4 if needed.
