You can visit the website’s “Contact Us” section to contact support for personal information inquiries, corrections, deletions, or consent withdrawals; you may also email mosucad@163.com or reach out via WeChat: mosucad.

2. Information We Process

1. During registration or sign-in, we process your phone number, account information, and device identifiers to create accounts, secure logins, and bind device credits. An internal ID is generated for your account, and custom usernames are not required. If you participate in invitation promotions via referral links or codes, relevant invitation data is processed. Passwords are saved only as encrypted verification credentials.

2. When you submit a translation, the client uploads only the selected text to be translated and data needed to complete the translation and calculate credits. The full DWG file is not uploaded. Block attribute values and attribute definitions are currently skipped and never sent. Our servers also retain task status, credit logs, and translation results for billing, recovery, and review.

3. Subject to your consent to relevant terms, original and translated phrases meeting length criteria, industry categories, and device identifiers may be retained for terminology statistics. These records are not considered anonymous data. Orders and payment statuses are generated upon recharging, with payments handled by Alipay.

4. When requesting an invoice, we process the order ID, invoice title, taxpayer ID (as required), and receipt email or phone number to verify transactions, issue and deliver electronic invoices, and comply with tax record obligations. Please contact support via the website’s “Contact Us” section to submit your request.

3. Data Use and Storage

1. Translation text is transmitted to MOSU backend servers and then routed via Tencent Cloud to DeepSeek translation models. SMS verification codes are handled by Tencent Cloud SMS services. The website loads Baidu Analytics scripts for site traffic statistics.

2. Personal data is retained only for the minimum period necessary to achieve the above purposes. Once purposes are fulfilled or retention periods expire, data is deleted or anonymized according to law. Orders, invoices, and other materials required by applicable laws are retained per statutory timeframes. Specific retention periods for accounts, translation jobs, terminology logs, invoices, and server logs, account cancellation steps, and Baidu Analytics settings remain subject to ongoing review and updates.

4. User Rights and Contact Information

To inquire, correct, or delete personal data, or withdraw consent, contact support through the website’s “Contact Us” section. Requests will be verified and handled in accordance with the law; where handling is legally not feasible, reasons will be provided.
