How 3D Printing Technology, Inc. (3DPTEK) collects, uses, shares and protects personal information when you visit lyafs.com, request a quotation, download a technical guide or work with our engineering and casting teams.
Your name, company, business e-mail, phone number and country, the machine or process you are interested in, and the message, drawings or specifications you choose to send us — plus basic technical data such as IP address and browser type.
To answer your enquiry, prepare a quotation, provide technical support, ship equipment, and meet our accounting, tax and export-control obligations.
Only the service providers that keep this website and our e-mail running, the carriers that deliver your order, and public authorities where the law requires it. We never sell or rent personal information.
You can ask for a copy of your information, have it corrected or deleted, or object to a particular use at any time. Write to sales@lyafs.com and we will respond within 30 days.
3D Printing Technology, Inc. (“3DPTEK”, “we”, “us”) is an industrial 3D printing equipment manufacturer and rapid-casting service provider. Our registered office is at No.7 Jin Yi Street, Shunyi District, Beijing, China, and we operate the website www.lyafs.com together with its translated language versions.
For the purposes of the EU and UK General Data Protection Regulation (GDPR) and comparable laws, 3DPTEK is the data controller for the personal information described in this policy. We are a business-to-business company: we use the information you give us to quote for, sell and support industrial equipment and casting services, not to profile consumers.
This policy covers personal information collected through our websites, quotation and contact forms, e-mail and telephone conversations, trade fairs, and our sales, shipping and after-sales activities. It does not cover the practices of third-party websites that we link to.
We keep collection to the minimum we need to answer a technical enquiry and to run our business. In practice there are three sources.
We do not ask for — and do not want to receive — special categories of personal data such as health, biometric, religious or political information. Our forms never ask for payment card numbers, and no file-upload field is active on this website. Please do not send us this kind of information.
We use personal information only for the purposes below, and we do not use it for automated decision-making or profiling.
Where the GDPR or UK GDPR applies, we rely on the following legal bases. Our own processing also complies with the Personal Information Protection Law of the People’s Republic of China.

Should we introduce website analytics or advertising tools, we will update this policy, list the new cookies here, and ask for your consent first where the law requires it.
We do not sell, rent or trade personal information. We disclose it only in the limited situations below, and every service provider acts on our written instructions.
We never share your technical drawings or specifications with another customer, and we treat customer project data as confidential business information.
Our company, our engineering team and our manufacturing facilities are in China. If you contact us from the European Economic Area, the United Kingdom, the United States or elsewhere, the information you send is transferred to and stored in China so that our engineers can answer you.
Where personal data of individuals in the EEA or the UK is transferred to us, we put in place appropriate safeguards — including the European Commission’s Standard Contractual Clauses and the UK International Data Transfer Addendum where they apply — together with technical and organisational measures such as encryption in transit. You can ask for a copy of the relevant safeguards using the contact details below.
We keep personal information only as long as we need it for the purpose it was collected for, and then delete or anonymise it.

| Quotations and proposals | Up to 24 months, so that we can honour or revise a price you were given |

| Server and security logs | Up to 12 months |

| Cookies | As shown in the cookie table above, or until you delete them |
Every page on this website is served over an encrypted HTTPS connection. Access to enquiry and customer records is restricted to the employees and partners who need it for the purposes described above, our website software is kept current and backed up routinely, and our team is instructed to treat customer project data as confidential.
No transmission over the internet can be guaranteed to be completely secure. Please do not send us drawings, tooling data or specifications that you are not authorised to share, and contact us first if you would prefer to exchange files through a secure channel.
Depending on where you live, you may have some or all of the following rights over the personal information we hold about you.
To exercise any of these rights, e-mail sales@lyafs.com with the subject line “Data request” and tell us what you would like us to do. We reply within 30 days, or within 45 days where the law allows, and we may ask you to confirm your identity before we act. Exercising your rights is always free of charge.
No. We do not sell or share personal information for cross-context behavioural advertising, and we do not use it to build advertising profiles. That is why this site shows no cookie-consent banner.
If you are a California resident, you have the right to know the categories and specific pieces of personal information we have collected, the purposes for which we use it and the categories of third parties to whom we disclose it; the right to request deletion or correction; the right to limit the use of sensitive personal information (we collect none); and the right not to be discriminated against for exercising any of these rights.
We honour equivalent requests from residents of other US states with similar privacy laws. The categories we collect and the purposes we use them for are exactly those listed in sections 1 and 2 of this policy, and the third parties are those listed in section 5.

Our website, machines and services are intended for businesses. We do not knowingly collect personal information from anyone under 16. If you believe that a child has sent us information, contact us and we will delete it.
Some of our pages link to third-party websites, such as industry associations, video platforms or material suppliers. Those sites have their own privacy practices, which we do not control; please read their policies before providing personal information.
We do not track visitors across other websites, so our site behaves the same whether or not your browser sends a Do Not Track or Global Privacy Control signal. If we ever introduce cross-site tracking, we will honour those signals.
We may update this policy when our services, our suppliers or the law change. The “last updated” date at the top of this page always shows the current version, and we will highlight any material change on this page before it takes effect. Continuing to use the website or work with us after an update means you accept the revised policy.

LYAFS Ads Connector ("the Connector") is an internal tool operated by 3D Printing Technology, Inc. This section explains how the Connector accesses, uses, stores and shares data obtained from Google APIs. It supplements, and does not replace, the rest of this Privacy Policy.
When a member of our staff authorises the Connector with their Google Account, the Connector requests the following OAuth scope:
Through this scope the Connector reads, for Google Ads accounts that we own or manage: campaign, ad group, ad and asset performance metrics; search terms and keyword statistics, including Keyword Planner volumes and forecasts; and the account identifiers needed to route API requests. The Connector does not create, edit or delete campaigns, does not change bids or budgets, and does not access Gmail, Drive, Calendar, contacts or any other Google product data.
Google data is used solely for our own internal advertising reporting and keyword research. It is not used for advertising retargeting of third parties, not used to determine creditworthiness or for lending purposes, and not used to train, fine-tune or improve any artificial-intelligence or machine-learning model.
Retrieved data is stored on access-controlled devices and servers that we operate, protected by operating-system account controls and encrypted transport (TLS). Report outputs are retained only as long as needed for internal analysis and are deleted when no longer required. OAuth credentials are stored locally on devices we control and can be revoked at any time.
We do not sell, rent, trade or otherwise transfer Google user data to third parties. Google data is not shared with advertising platforms, data brokers or information resellers. It is disclosed only where the law requires it, or to service providers acting on our behalf under confidentiality obligations and only to the extent necessary to run the Connector's hosting and storage.
LYAFS Ads Connector's use and transfer to any other app of information received from Google APIs will adhere to the Google API Services User Data Policy, including the Limited Use requirements.
You can revoke the Connector's access to your Google Account at any time at myaccount.google.com/permissions. To request deletion of data the Connector has stored, or to ask any question about this section, contact sales@lyafs.com. We will respond within 30 days and delete the data unless we are legally required to retain it.
Our team answers data-protection questions in English and Chinese, usually within two working days.
