When purchasing products on this Platform, you shall provide true, accurate, complete, and valid purchase-related information, including but not limited to the consignee’s name, contact phone number, detailed delivery address, and email address (if an electronic invoice is requested).

If the purchase-related information you provide is false, inaccurate, incomplete, or invalid (e.g., a blank contact phone number, an ambiguous delivery address), this may result in issues such as failure to generate the order normally, payment failure, inability to deliver the goods, or rejection of after-sales requests. Such problems may further lead to order cancellation, delivery delays, or goods being returned. We reserve the right to refuse to process the relevant orders or after-sales requests based on the actual circumstances.

2.2. Verification and modification of purchase information

We reserve the right to verify the validity of the purchase information you provided subsequent to order placement and prior to shipment (e.g., contacting you to verify the delivery address, checking the consistency between payment information and order details). If any abnormal information is identified (e.g., a large number of orders placed via the same email address or to the same delivery address within a short period, with different delivery addresses), we may suspend order processing and notify you to supplement relevant information. You shall cooperate with such verification within 24 hours of receiving the notification. Failure to cooperate within the specified time frame will result in the automatic cancellation of the order.

After order placement and prior to shipment, you may request to modify the delivery information (including the consignee’s name, contact phone number, and delivery address). To submit such a request, you must contact customer service and provide the order number along with your registered email address for identity verification. Subsequent to shipment, due to logistics constraints, modifications to the consignee’s name and contact phone number will not be permitted, with specific rules subject to those of the logistics partner.

2.3. Purchase information storage and protection

Pursuant to the Privacy Policy, we will encrypt and store your purchase information, which will be used solely for scenarios directly related to your purchase (e.g., logistics and distribution, after-sales support such as product returns and exchanges, invoice issuance) and shall not be used for any other unrelated purposes.

Your purchase information will be retained for 12 months following order completion (i.e., from the date of confirmed receipt), after which it will be anonymized or deleted in accordance with the Privacy Policy. If you need to inquire about historical orders, you shall provide the order number and verify via your registered email address during the retention period.

We will adopt technical measures (e.g., data encryption, access control) and management measures (e.g., internal permission approval) to safeguard the security of your purchase information and prevent the disclosure, loss, or tampering of such information.
