Privacy Policy

1. Overview & Operating Entity

Welcome to the official platform of niumodao (牛魔刀) (domains: www.niumodao.store and niumodao.store). The platform is operated by niumodao, a specialized garment manufacturing factory established in 2023 and located in Yuzhou District, Yulin, Guangxi Zhuang Autonomous Region, China. We focus on flexible denim apparel manufacturing, small-batch agile response, and OEM/ODM private label solutions.

We hold your privacy, trade secrets, and brand design assets with the utmost respect and care. This Privacy Policy details our commitment to transparent data collection, responsible usage, and robust protection.

2. Information We Collect

In compliance with the principle of data minimization, we collect only information essential to providing cost estimates, prototyping, sampling, and manufacturing:

• Account Credentials: When you register an account, we record your email address, contact name (optional), and securely salted & hashed passwords (using Scrypt). We never store plaintext passwords.
• Request for Quote (RFQ) Data: When submitting an inquiry through our cost estimator or product catalog, we capture your brand name, preferred contact channel (WhatsApp / Email), estimated order volume, timeline expectations, tech pack links, notes, and the technical specification snapshot of your configuration. You can submit an RFQ without creating an account; the business email you provide is used to respond to that inquiry.
• Client-Side Local Storage: To provide a responsive, uninterrupted experience, your unfinished cost calculations and trim designs are stored in your browser's local storage (LocalStorage). These drafts stay on your device until you choose to submit or save them.
• Security & Diagnostic Logs: To defend against automated credential stuffing and malicious abuse, our servers log keyed cryptographic hashes of submitter IP addresses (never raw IP addresses), browser User-Agent strings, and unique Request IDs.

2.1 AI Sourcing Assistant

When you choose to use the AI sourcing assistant, we process the message text, the page context, and an optional product or style identifier to generate a reply. You do not need an account, email address, or phone number to chat.

Messages are sent to our configured LLM provider for processing. We do not store raw chat transcripts on NIUMODAO servers in the current release; the provider processes the message under its own data-retention terms. Please do not include sensitive personal data in a chat.

AI replies are advisory. They are not a binding quotation, certification, or delivery commitment. You can always use WhatsApp or email instead.

3. How We Use Your Information

Your information is processed strictly for legitimate manufacturing and business purposes:

• Calculating unit production costs and preparing official factory quotes and technical confirmations;
• Organizing fabric sourcing, sample prototyping, trim production, and manufacturing line schedules;
• Communicating regarding sample approvals, order milestones, and international freight tracking;
• Delivering one-time verification codes via Tencent Cloud Simple Email Service (SES);
• No Data Brokering: We never sell, rent, or lease your personal or business data to any third party.

4. Intellectual Property & Confidentiality

As an OEM/ODM private-label manufacturer, brand confidentiality is our core standard:

All brand trademarks, vector logos, hangtag artwork, technical drawings, pattern data, and tech packs you upload or provide remain 100% your exclusive intellectual property. niumodao will never replicate, resell, or distribute your proprietary designs to other clients without your explicit written consent.

5. Data Retention & Security Standards

All network communication is strictly enforced over HTTPS (TLS 1.3). Verification challenges are stored as keyed HMAC digests with rapid expiration. Production databases are isolated and backed up regularly. Inquiry data is retained only for standard business fulfillment, auditing, and warranty periods.

6. Your Rights

You maintain full rights to access, update, export, or delete your account information at any time via your account portal (/en/account) or by contacting our team directly.

7. Contact & Compliance
