Privacy Policy
Effective date: October 29, 2026
This Privacy Policy explains how 3D Printing Catalog ("we," "us," or "our") collects, uses, and shares information when you visit 3dprintingcatalog.com (the "Site"). By using the Site, you agree to the practices described here.
Information We Collect
Information collected automatically. When you visit the Site, we, our service providers, and our partners may automatically collect:
- Device and browser information, such as browser type, operating system, device type, language, and screen size;
- IP address and general location (such as city or state) based on your IP address;
- Pages you view, time spent on pages, and the date and time of your visit;
- The referring URL or website that sent you to the Site, including campaign or tracking parameters;
- Click data, such as which links, ads, or offers you click.
Information you choose to give us. If you email us, we receive your email address and anything you include in your message.
Sensitive information. We do not ask for sensitive information on the Site, such as Social Security numbers, financial account numbers, or health or dental information. Please do not send us this kind of information. Third-party sites you visit from our links may ask for information. Their own privacy policies apply to it, not this one.
Cookies and Similar Technologies
We and our partners use cookies, pixels, web beacons, local storage, and similar technologies. We use them to run the Site, remember preferences, measure traffic, prevent fraud, and support advertising.
How to control them: Most browsers let you block or delete cookies in their settings. Some browsers and extensions also offer tracking protection. If you block cookies, some parts of the Site may not work properly. Deleting cookies may also delete your opt-out preferences, so you may need to opt out again.
Third-Party Advertising and Search Partners
The Site and the pages we link to may show ads and search results from third-party advertising and search partners, such as System1 and Google. These partners may set and read their own cookies and similar technologies, and collect information about your visit to the Site and other websites over time. They may use this information to serve, personalize, and measure ads, including interest-based ads, and to detect fraud. Their use of information is governed by their own privacy policies.
You can learn more about interest-based ads, and opt out of them from participating companies, here:
- Digital Advertising Alliance: https://optout.aboutads.info
- Network Advertising Initiative: https://www.networkadvertising.org/choices
- Google Ad Settings: https://adssettings.google.com
If you opt out, you will still see ads, but they may be less relevant to you. Opt-outs are usually tied to a specific browser and device.
Analytics
We use third-party analytics services to understand how visitors find and use the Site, such as which pages are popular and how visitors arrive. These services may use cookies and similar technologies to collect information automatically. You can limit analytics through your browser's cookie settings or any opt-out tools the analytics providers offer.
How We Use Information
We use information to:
- Run, maintain, and improve the Site and its content;
- Understand traffic and how visitors use the Site;
- Show ads and measure their performance, and track clicks for partner reporting and compensation;
- Detect, prevent, and deal with fraud, invalid traffic, and security problems;
- Answer your emails and requests;
- Comply with the law and enforce our Terms of Use.
How We Share Information
We do not sell personal information for money in the traditional sense. We may share information as follows:
- Advertising, search, and analytics partners. We share information with them, or allow them to collect it through cookies and similar technologies, as described above. Under some US state privacy laws, this may count as a "sale" of personal information or "sharing" for targeted advertising. See "Your Choices and Rights" below.
- Service providers. These include companies that host, maintain, secure, or help operate the Site, who may handle information on our behalf.
- Legal and safety reasons. We may share information to comply with the law, legal process, or government requests; to protect our rights, users, or others; or to investigate fraud or security issues.
- Business transfers. If there is a merger, sale, or transfer of all or part of our business or assets, information may be transferred as part of it.
- With your consent or at your direction.
We may also share information that is aggregated or de-identified and cannot reasonably be used to identify you.
Links to Third-Party Sites
The Site contains links to third-party websites and search results pages. Once you leave our Site, this Privacy Policy no longer applies. We are not responsible for the privacy practices of third parties. Please review their privacy policies before giving them any information.
Data Retention and Security
We keep information only for as long as we reasonably need it for the purposes in this Policy, or as the law requires or allows. We use reasonable administrative, technical, and physical safeguards to protect information. However, no website or method of transmitting data over the internet is completely secure, so we cannot guarantee absolute security.
Your Choices and Rights
Your choices. You can control cookies through your browser and opt out of interest-based ads using the links above. Where required by applicable law, we will honor recognized browser-based opt-out preference signals, such as Global Privacy Control.
US state privacy rights. Depending on where you live, state law may give you some or all of these rights:
- To know or access the personal information we have about you;
- To correct inaccurate personal information;
- To delete personal information;
- To receive a copy of your personal information in a portable format;
- To opt out of the "sale" or "sharing" of personal information, targeted advertising, or certain profiling;
- To appeal our decision about your request.
How to make a request. Email privacy@3dprintingcatalog.com and tell us your state of residence and the right you want to use. We may need to verify your identity before we act on your request. Because we collect limited information, we may ask for details such as the approximate date of your visit and the device you used. If an authorized agent is making the request for you, we may ask for proof that they are authorized. We will respond within the time required by applicable law. If we deny your request, you may appeal by replying to our decision email with "Appeal" in the subject line. We will not discriminate against you for exercising your privacy rights.
