Customer support privacy policy
Effective 18 October 2026
This policy covers MINGCRAFT Customer Support: our contact form, support email and staff support workspace. It explains the Gmail connection used by our team, as well as information provided by people contacting us.
Who operates this service
MINGCRAFT is operated by 杭州衫福贸易有限公司, 中国浙江省杭州市拱墅区华电弄76号二楼2390室, postal code 310014, China. For support or privacy requests, email wangyulongnb6666+mingcraft@gmail.com.
Information we handle
We record the name, email address, subject, enquiry type, optional order number and message you submit. Support records can also include email sender and recipient addresses, message and thread identifiers, timestamps, eligible attachments, staff replies, internal notes, assignment, status and delivery records. We use these records to answer enquiries, investigate order or delivery issues, maintain conversation history and protect the service against abuse.
How the Gmail connection works
Only the store Owner connects our designated Gmail account using Google OAuth. Customers do not need to grant access to their own Gmail accounts to contact us. Google grants mailbox-wide read access (gmail.readonly) and permission to send email (gmail.send); Google does not limit those permissions to a single label.
Our application imports incoming messages only when they carry the selected MINGCRAFT/Support label and are newer than the synchronization start time. It does not import private mail outside that label or automatically import historical mail. Staff should keep unrelated mail out of this label. We also use Gmail to check the connected account, list labels, track synchronization and check the outcome of support messages sent by the application. Replies are sent only when authorized staff explicitly queue them.
Use, sharing and human access
Authorized support staff and the store Owner can read support records to handle enquiries. We do not sell Google user data, use it for advertising or credit decisions, or use it to train general-purpose AI models. Contacting support does not subscribe you to marketing emails. Internal notes are not emailed to customers.
Google processes mail delivery and the authorized Gmail connection. Our infrastructure providers, including Amazon Web Services, host the application and backups. Information may also be handled where necessary for security, legal obligations or the enquiry you asked us to resolve. Our access, use and transfer of Google API data follow the Google API Services User Data Policy, including its Limited Use requirements.
Storage and retention
Support records are stored in our application database; sensitive message fields, supported attachment contents and OAuth tokens are encrypted at application level. Access to the staff workspace requires an authorized account. The service is hosted in the United States and operated by staff in China, so support information can be processed in these locations. Encryption does not make a system risk-free.
We keep support history as needed to handle enquiries, follow up on orders, resolve disputes and meet applicable recordkeeping obligations. There is currently no automatic deletion schedule for closed conversations. Database backups and older backup versions can retain copies for longer; deleting a live record does not immediately erase every backup copy. Backups are restricted to recovery use.
Control, disconnection and deletion requests
The Owner can pause synchronization or disconnect Gmail in mailbox settings. The account holder can also revoke access through Google Account connections. Disconnecting clears the application’s current connection tokens and stops synchronization; previously stored support conversations remain, and the website contact form continues to accept enquiries.
To request access, correction or deletion of your support information, contact the address above and provide your enquiry reference if available. We may verify your identity and will explain any information that must be retained for legal, security or dispute purposes. These requests are handled manually; no automatic deletion or fixed deletion deadline is promised here. Deleting application records does not itself delete messages in Gmail.
Updates and related terms
We will update this page when these practices change. See also the customer support terms. This policy describes support data handling; it does not replace notices shown in other store services.
