MOSU CAD Translation Terms of Service

1. Services and Operator

MOSU CAD Translation services are operated by 海口龙华墨鼠商贸工作室. Services include the CAD client plugin (supporting AutoCAD, ZWCAD, and GstarCAD), official website, cloud engineering text translation, and credit services. By downloading, installing, registering, or using these services, you acknowledge that you have read and agreed to all terms in this Agreement.

2. Account Registration and Security

1. Users must register or sign in using a legally acquired mobile phone number verified via SMS. Each phone number corresponds to a single, unique MOSU account.

2. Users are responsible for maintaining account confidentiality and must not lend, lease, or transfer accounts to any third party. Any credential compromises or account losses arising from user actions are borne solely by the user.

3. Credit Recharges, Usage, and Refund Policies

1. Each quote is billed separately; batch translation quotes each DWG separately. Identical source text is counted once within a quote, and formatting placeholders and whitespace are excluded. The first 3,000 valid source characters cost 1 credit per 100 characters; characters 3,001–20,000 cost 1 credit per 1,000; any characters above 20,000 cost 1 credit per 5,000. Each tier rounds up separately. The quoted credits are reserved when a job starts. Final settlement charges only text actually written back, refunds any unused reserved credits, and never exceeds the quote. The estimated credits and scope are shown before confirmation.

2. Purchased credits are valid for 2 years from the date they are credited to the account; bonus credits are valid for 1 month from the date they are credited. If users encounter incompatibility preventing use or seek a refund, please contact support via the website’s “Contact Us” section with your transaction ID within 7 days of purchase before significant credit usage. Upon verification, unconsumed credits will be refunded proportionally via the original payment channel. For invoices, please contact support.

3. Confirmed failed tasks due to network interruption or server anomalies do not deduct credits. If a status displays “pending review”, users can contact support to verify ledger status; do not resubmit the same task.

4. Drawing Data and Disclaimer

AI machine translation outputs are for engineering assistance only. Before final plot release, contract signing, or fabrication, qualified professional engineers must manually review and verify all critical dimensions, tolerances, materials, and technical specifications.
