This Privacy Policy explains how ZIXEL TECHNOLOGIES PTE. LTD., Shanghai Ziqian Technology Co., Ltd., and their affiliates (collectively, "Zixel," "we," "us," or "our") collect, use, store, share, and protect personal information in connection with Zixel 3D CAD and related services. For the English-language website and Services, ZIXEL TECHNOLOGIES PTE. LTD. is generally the primary contracting entity. Depending on the product, region, and customer relationship, Shanghai Ziqian Technology Co., Ltd. or another Zixel affiliate may also handle personal information while providing operations, support, compliance, or other service functions. We collect personal information only when it is reasonably necessary to provide the Services, maintain security, comply with legal obligations, or support lawful customer administration requirements. If particular information is optional, you may choose not to provide it, although some features may then be unavailable. Sensitive device permissions, such as access to the camera, microphone, or photo library, are disabled by default and are requested only when a feature needs them. You can withdraw those permissions at any time in your device or application settings. This Privacy Policy applies to the official website at www.zixel3d.com/en together with our web applications, desktop or mobile applications, SDKs, APIs, and any other products or services that link to this Privacy Policy. It does not apply to third-party products or services that operate under their own privacy notices. Please read this Privacy Policy carefully. It describes the types of information we process, how you can manage your information, and the rights available to you under applicable law.

I. How We Collect and Use Personal Information

We collect personal information that you provide directly, information generated through your use of the Services, and information supplied by Customers or authorized third parties where permitted by law and necessary for service delivery.

Account Services

When you register, sign in, recover an account, request support, or use features that require identity verification, we may collect information such as your name, email address, mobile number, company or organization details, login credentials, verification records, and other information reasonably needed to authenticate you and administer your account. If you register on behalf of a Customer, we may process organization details, business verification information, and administrator contact information so that the Customer can open, manage, and secure its workspace. Customers may configure profile information for Authorized Users, including names, avatars, team membership, and directory details. That information may be visible within the Customer's organization according to the workspace settings chosen by the Customer.

Project Collaboration and Content

When you upload designs, files, comments, images, videos, or other materials to the Services, we process that content and related metadata so that we can store it, display it to permitted collaborators, synchronize versions, maintain activity history, and enable core collaboration features. If you use features that capture or share images, video, or audio, we may request access to the camera, microphone, or local media library for that specific purpose. Refusing those permissions will disable the relevant feature but will not block unrelated features.

Search, Messages, and Support

We may process search terms, browsing activity within the Services, support requests, and communication records so that we can provide search results, troubleshoot issues, respond to requests, and improve the user experience. We may also use the contact information you provide to send service notices, verification messages, security alerts, billing notices, and, where permitted by law, marketing or event communications. You can opt out of non-essential marketing messages using the instructions in the message or by contacting us.

Security and Operations

To maintain service reliability, security, and fraud prevention, we may collect device and log information such as IP address, device model, operating system version, application version, browser type, language, identifiers made available by the operating environment, network status, crash data, usage logs, and approximate time-zone information. Where a security or verification workflow requires it, we may process additional information such as identity-verification records or device sensor information used to complete the requested verification step. If you choose not to provide that information, some security-sensitive features may be unavailable.

Clipboard and Sharing Features

When you use copy, paste, or sharing features, the Services may access clipboard content or similar local data only as needed to complete that action. If a Customer enables organizational security controls, those controls may limit how content can be copied or shared outside the Customer's workspace.

Changes in Purpose

If we need to process personal information for a purpose that is not reasonably related to the purpose originally disclosed to you, we will provide additional notice and obtain consent where required by applicable law.

II. Cookies and Similar Technologies

We use cookies, local storage, SDK storage, and similar technologies to keep you signed in, remember preferences, maintain security, analyze traffic, measure performance, and improve the Services. Some of these technologies are required for core functionality, while others support analytics, service improvement, or personalization. You can control cookies and similar technologies through your browser or device settings, although disabling them may affect how parts of the Services function.

III. Partners, Transfers, and Disclosures

We may share personal information with service providers, infrastructure vendors, analytics or customer-support partners, affiliates, and other processors that help us operate the Services, provided they are subject to confidentiality and data-protection obligations. If you use the Services through a Customer account, that Customer and its administrators may access or control personal information and workspace content associated with your use of the Services, subject to their own policies and applicable law. We may disclose personal information when required to do so by law, regulation, court order, governmental request, or to protect the rights, property, safety, and security of Zixel, our users, or others. We may also disclose personal information in connection with a merger, financing, acquisition, reorganization, sale of assets, or similar corporate transaction, subject to applicable confidentiality and legal requirements. We do not sell personal information in exchange for money. If we ever materially change our sharing practices, we will update this Privacy Policy and provide any notice or choices required by law.

IV. How We Store Personal Information

Storage Location

In accordance with applicable law and our service operations, we currently store personal information collected through the Services in Singapore. If a future business or technical need requires cross-border transfers, we will implement the safeguards and procedures required by applicable law.

Retention Period

We retain personal information only for as long as reasonably necessary to provide the Services, satisfy the purposes described in this Privacy Policy, comply with legal obligations, resolve disputes, enforce agreements, and maintain security. We may keep information for longer where:

law or regulation requires a longer retention period;
retention is reasonably necessary for audit, accounting, or dispute resolution;
a Customer lawfully requires continued retention or management of organizational data; or
the information must be preserved for fraud prevention, security review, or other legitimate compliance purposes.

V. How We Protect Personal Information

We implement administrative, technical, and organizational safeguards designed to protect personal information, including access controls, encryption, logging, internal permission management, secure development practices, and measures intended to reduce the risk of unauthorized access, disclosure, or misuse. Even so, no system can be guaranteed to be completely secure. Internet transmission, storage systems, and third-party infrastructure always involve some level of risk. You should help protect your own information by choosing strong passwords, securing your devices, and not sharing credentials with others. If we become aware of a personal information security incident, we will take remedial measures and provide notice to affected individuals and regulators where required by law. This Privacy Policy does not apply to information you provide directly to third-party websites, applications, or services that are linked from the Services or otherwise used by you outside our controlled environment.

VI. Managing Your Personal Information

Depending on your role, product version, jurisdiction, and the type of information involved, you may have rights to access, correct, update, delete, restrict, or object to certain processing of your personal information, or to withdraw consent where consent is the legal basis for processing.

Permissions and Account Settings

You can manage many device-level permissions, such as camera or microphone access, through your device settings. You may also update certain profile, login, and account details through the account settings made available in the Services.

Requests to Access, Correct, or Delete Information

Individual Users may submit requests through available account or support channels to access, correct, or delete eligible personal information. Authorized Users may need to contact their Customer or workspace administrator first, because the Customer may control organizational account data and settings. We may ask you to verify your identity before acting on a request. In some cases, we may decline or limit a request where permitted by law, for example if the request would adversely affect the rights of others, undermine security, or conflict with a legal retention obligation.

Account Deletion

If you ask us to delete your account, we may verify your identity, account security status, and other relevant information before processing the request. Account deletion is generally irreversible. When deletion is completed, we will delete or anonymize personal information as required by applicable law, except where retention remains necessary for legal, security, compliance, Customer-management, or dispute-resolution purposes.

Complaints and Service Closure

If you believe your privacy rights have been violated, you may contact us using the methods listed below. If we ever stop operating the relevant Services, we will stop collecting personal information through them and will handle the information we already hold in accordance with applicable law.

VII. Minors

The Services are primarily intended for adults. If you are under 18, you should review this Privacy Policy with your parent or legal guardian and use the Services only with their consent and supervision. If you are a parent or guardian and believe that a minor has provided us with personal information in a manner inconsistent with applicable law, please contact us so that we can review and address the issue.

VIII. Revisions to This Privacy Policy

We may update this Privacy Policy from time to time to reflect changes in law, our services, our data practices, or our security and operational needs. If we make material changes, we will publish the updated version and provide any notice required by law before the revised policy takes effect. Your continued use of the Services after the updated version becomes effective means that you acknowledge the revised Privacy Policy, to the extent permitted by law.

IX. Contact Us

If you have questions, comments, or requests about this Privacy Policy or our handling of personal information, you may contact us through the customer-service portal on our official website ( www.zixel3d.com/en ) or by email at contact@zixel3d.com . We do not usually charge a fee for reasonable privacy requests. However, where permitted by law, we may charge a reasonable fee or decline to act on requests that are repetitive, excessive, technically disproportionate, or not made by the relevant data subject or an authorized representative. After we verify your identity and understand the scope of your request, we generally aim to respond within 15 business days, unless a different period applies under local law or the request is unusually complex.

X. Other Provisions

This Privacy Policy may be made available in more than one language. If there is any inconsistency between language versions, the simplified Chinese version will prevail, unless applicable law requires otherwise. Headings are included for convenience only and do not affect the interpretation of this Privacy Policy.
