Mixware 3D Privacy Policy

1. Introduction

Your privacy matters to us. This Privacy Policy ("Policy") explains how the Mixware 3D mobile application, related websites, cloud services, and companion 3D printers and related services (collectively, the "Mixware Services" or "Services") collect, use, store, share, and protect your personal information, and how you can access and control it.

Mixware Services are intended for users aged 13 and above, and are currently distributed primarily via Google Play and the Apple App Store (overseas regions) and rated 13+. Users under 13 in the United States, users under 14 in China, and users below any lower age set by other applicable laws must not register for or use the Services. We do not provide the Services to such users and do not knowingly collect their personal information. If you are a minor aged 13–18 (or 14–18 in China), please use the Services under the guidance of a parent or legal guardian (collectively, "parent" or "guardian"), and ask your guardian to read this Policy.

We process personal information in accordance with applicable laws, including but not limited to the U.S. Children's Online Privacy Protection Act ("COPPA"), the EU General Data Protection Regulation ("GDPR"), and, for users in China, the PRC Personal Information Protection Law ("PIPL") and the Provisions on the Protection of Children's Personal Information Online.

Your acknowledgment: By registering, logging in, or otherwise using Mixware Services, you (and, if you are a minor, your parent or guardian) confirm that you have read, understood, and agree to this Policy. If you do not agree, please discontinue use of the Services.

Note: "Personal information" means any information relating to an identified or identifiable natural person, excluding anonymized information.

2. Information We Collect

The information we collect depends on how you use the Services, your choices (including privacy settings), the features you use, and applicable law. We always follow the data minimization principle and collect only what is necessary to provide the Services. All personal information we collect is transmitted using encryption. We do not sell your personal information, nor do we use it for third-party purposes unrelated to providing the Services. To provide features you actively choose to use—such as cloud storage and AI creation—the images, text prompts, and models you upload or input are transmitted to the relevant processors as described in Section 5 solely to deliver those features; this is not a sale of, or sharing for the recipients' own purposes of, your personal information.

2.1 Information You Provide Directly

2.2 Information Collected Automatically When You Use the Services

2.3 Information We Receive from Third-Party Sources

• Public profile information shared by third-party login platforms (Google, Apple) within the authorized scope;
• Business partners/resellers (if applicable): when you purchase products through an authorized reseller, the reseller may lawfully share necessary transaction information with us to fulfill the service.

2.4 Information We Do Not Collect

• Full payment card numbers or payment passwords;
• The content of your calls or text messages;
• Personal information of users under 13 (U.S.) or under 14 (China);
• Any information for advertising purposes — we do not integrate any advertising SDK.

3. How We Use Your Personal Information

We process your personal information only to the extent necessary for the following purposes:

1. Provide and maintain the Services: account registration and login, identity verification, device pairing and management, cloud slicing, cloud printing, print task management, firmware updates (OTA), and community browsing/uploading/downloading/interaction;
2. Provide AI creation features: operate "Image to 3D", "Text to 3D", and "Draw to 3D", transmitting necessary input to third-party AI providers and receiving generated results;
3. Customer support and after-sales service: respond to inquiries, resolve issues and complaints, and provide warranty and returns;
4. Security and content compliance: detect and prevent fraud, abuse, security risks, and technical issues; moderate community content to protect Mixware, our users, and the public;
5. Product improvement and analytics: with your consent, conduct experience improvement programs, user research, and anonymized statistics (statistical results do not constitute personal information);
6. Legal compliance: comply with applicable laws and respond to legitimate requests from regulators and judicial authorities.

Legal bases: We process personal information based on the following legal bases: (1) consent; (2) performance of a contract with you; (3) compliance with legal obligations; (4) protection of vital interests; and (5) our legitimate interests (e.g., security and fraud prevention). Information of minors is processed only to the minimum extent necessary, with guardian consent where required, and never for marketing.

What we will not do: We will not use your personal information for purposes incompatible with this Policy without your consent. We do not sell your personal information, nor do we share it outwardly for the recipients' own purposes (content you upload is transmitted to the relevant processors as described in Section 5 solely to deliver the features you request). We do not show any advertising, and we do not use your information for advertising purposes.

4. Cookies and Similar Technologies

• On our websites and embedded web pages within the app, we may use cookies, pixel tags, local storage, and similar technologies to: maintain login sessions, remember preferences, and perform analytics (only with consent).
• We do not use cookies or similar technologies for cross-site tracking or behavioral advertising, and we have not integrated any advertising-related technology.
• You can manage or disable cookies through your browser or app settings; disabling them may affect some functionality.

5. Sharing, Delegated Processing, and Third-Party Services

5.1 Sharing Principles

We do not sell your personal information, nor do we use it for purposes unrelated to providing the Services or "share" it outwardly with third parties (where "share" means sharing for the recipients' own purposes). Where necessary to provide the Services, we delegate processing or disclose necessary information in the following circumstances—the images, text prompts, and models you actively upload or input are used solely to deliver the features you request (such as cloud slicing and AI creation), and always on a data-minimized basis:

1. Content you choose to make public or authorized sharing: Content you publish publicly in the community (such as public models, display name, avatar) is visible to other users;
2. Third-party service providers (delegated processing): To provide the Services, we delegate necessary information to the following categories of providers (see Annex 1):
   • Cloud and hosting providers: Alibaba Cloud (data in mainland China), overseas cloud providers (data of users outside China, e.g., AWS), for data storage and infrastructure;
   • AI service providers: Tencent Hunyuan (Hunyuan 3D), Tripo, and others, to process AI creation inputs and outputs;
   • Third-party login providers: Google, Apple (you may also register directly with your email; email information is covered in Section 2.1);
   • Payment and logistics providers (if applicable): for orders and after-sales;
3. Affiliated companies (if applicable): we may share necessary information within the Mixware group for unified accounts and cross-product services; any change of purpose by an affiliate requires new consent;
4. Legal requirements: where disclosure is required by applicable law, legal process, litigation, or mandatory government request, or where reasonably necessary to protect the rights, property, or safety of Mixware, our users, or the public.

All third-party service providers process your information solely for the purpose of providing the Services to you and are bound by confidentiality and security obligations. We currently do not integrate any advertising, analytics, or push-notification third-party SDKs.

5.2 Third-Party AI Services (e.g., Tencent Hunyuan, Tripo)

• When you use AI creation features, the images, drawings, text prompts, and generated models you actively upload or input (collectively, "Creation Content") are transmitted to third-party AI service providers (such as Tencent Hunyuan and Tripo). Creation Content is content you provide; it is transmitted solely to generate 3D models for you and is not a sale of, or sharing for the recipients' own purposes of, your personal information.
• On training and commercial use: we require, and use reasonable efforts to bind by contract, third-party AI providers so that, without your explicit consent, they will not use your Creation Content for AI model training or any commercial purpose unrelated to providing the AI service; each provider's privacy practices are governed by its own official privacy policy (see Annex 1).
• Cross-border transfer note: Tencent Hunyuan is an in-China service (data stored in China); Tripo is an overseas provider. For users in mainland China, processing Creation Content via Tripo constitutes a cross-border transfer, which we handle under the cross-border safeguards in Section 6 (e.g., standard contracts / certification / separate consent).

5.3 Advertising Statement

We currently do not show any advertising: Mixware Services do not integrate any third-party advertising SDK, do not display third-party ads in the app or on our websites, and do not collect, use, or share any of your personal information for advertising purposes. If we offer advertising services in the future, we will notify you in advance through an update to this Policy and in-app notice, and will do so only in compliance with applicable law (including rules protecting minors).

5.4 Merger, Acquisition, or Asset Transfer

In the event of a merger, acquisition, reorganization, or asset transfer, we may transfer related personal information as part of the transaction. We will require the successor to remain bound by this Policy; if the purpose of processing changes, new consent will be obtained.

6. Storage and Cross-Border Transfers

• Storage location:
  • Personal information collected and generated in the People's Republic of China is stored in data centers located in mainland China (currently provided by Alibaba Cloud);
  • Personal information of users outside China (e.g., via Google Play) is stored in overseas data centers located in the user's region or in regions where we or our cloud providers operate (for example, AWS and other cloud providers). The specific server regions may change as our business evolves; we always follow the principles of local storage and compliant storage.
• Cross-border transfers: Where cross-border transfers occur, we implement one or more of the following safeguards: personal information protection certification, Standard Contractual Clauses (SCCs), adequacy decisions, or separate consent obtained before transfer, ensuring compliance with applicable law.
• Retention: We retain personal information only for as long as necessary to fulfill the purposes described in this Policy (see Section 8), after which it is deleted or anonymized.

7. Protection of Minors (Important)

7.1 Age Restrictions

If we learn that we have collected personal information from a user under 13 (U.S.) or under 14 (China) (or below any lower age set by other applicable laws) without guardian consent, we will promptly delete the information and close the related account. If you believe we may have collected such information, please contact us immediately through Section 12.

9. Data Security

We implement industry-standard physical, organizational, and technical safeguards, including:

• Encryption in transit: all personal information is protected by encryption protocols such as TLS/HTTPS during transmission;
• Encryption at rest: sensitive data (such as passwords and print files) is encrypted; passwords are stored as irreversible hashes;
• Access controls: least-privilege, need-to-know access with role-based permissions;
• Security audits: periodic security assessments, vulnerability scanning, and penetration testing (where applicable);
• Incident response: an incident response plan; in the event of a security incident, we will notify you and report to regulators as required by law.

Please understand that no method of transmission over the Internet or method of electronic storage is 100% secure. Please protect your account password, never share it with others, and log out when using shared or public devices.

10. Your Rights

You have the following rights regarding your personal information (a parent or guardian exercises the corresponding rights on behalf of a minor, see Section 7):

Response time: We will respond to verified requests within 15 business days; reasonable requests are free of charge, while repeated or excessive requests may incur a reasonable fee. Data that cannot be deleted immediately due to backup or security constraints will be securely isolated until it can be deleted.

11. Changes to This Policy

We may update this Policy from time to time. When we do, we will update the "Last Updated" date at the top and, depending on the significance of the change, notify you via in-app notice, email, or other appropriate means. Material changes (e.g., to processing purposes, sharing recipients, or minors' data handling) will be notified prominently at least 30 days before they take effect. We encourage you to review this Policy periodically.
