Service operator / supplier: Aibianma (Hangzhou) Network Technology Co., Ltd.. Registered address: 浙江省杭州市余航区仓前街道龙泉路2号2幢132室. Tax identification / unified social credit code: 91330106MA2KK7ME1Y.

For transactions processed by Paddle, Paddle Buyer Terms and Paddle's Refund Policy also apply. If there is any conflict, mandatory consumer law and the applicable Paddle buyer terms control for the transaction.

• Unless required by applicable law, completed transactions are generally non-refundable and non-exchangeable.
• Paddle or we may approve a refund on a discretionary, case-by-case basis within the period allowed by Paddle's policy or applicable law.
• Refunds may be declined where there is evidence of fraud, refund abuse, or manipulative behavior.
• This policy does not affect your rights where a product is not as described, is materially defective, or is not fit for purpose.

Where local consumer protection laws grant unconditional withdrawal or cancellation rights, those rights override this policy.

Based on Paddle's current policy, eligible consumer transactions may include a 14-day withdrawal period in the EU / EEA / Switzerland / United Kingdom and in Turkey / Israel, a 7-day cancellation period in China / South Korea / Brazil / Canada, and a 5-day cancellation period in Singapore. The latest jurisdiction-specific details are available at https://www.paddle.com/legal/refund-policy.

Where local law allows it, some withdrawal rights for digital content may end after download, streaming, first access, or other use if you expressly consent to immediate performance and acknowledge the waiver.

2. You can also request help directly from Paddle at https://paddle.net, or contact us at qingdou888@gmail.com for product-specific assistance.
3. Submit the request within the statutory or discretionary period that applies to your transaction.
4. If the issue involves a technical or product defect, please include the relevant order details and a clear description of the issue so it can be reviewed efficiently.

If you experience a persistent technical issue or a material defect affecting VideoTool, please contact us first at qingdou888@gmail.com so we can attempt to resolve the issue.

If the issue cannot be resolved, you may escalate the refund request through Paddle support at https://paddle.net. Where there is evidence of a material technical or product defect, refunds will be handled in accordance with applicable consumer protection law and the applicable Paddle policy.

If a refund is approved, it will be returned to the original payment method where possible and is typically processed within 14 days after approval.

If a refund is issued, access to the refunded paid product, credits, subscription, or related features may be reduced, revoked, or terminated.

Before initiating a chargeback or payment dispute, please contact Paddle so the request can be reviewed through the standard refund process. Access to the relevant product may be temporarily suspended while the matter is under review.

If a transaction is not eligible for a refund, you may still cancel a subscription at any time to prevent future billing. Unless applicable law requires otherwise, cancellation takes effect at the end of the current billing period.
