Unlayered 3D™

Privacy Policy

Last Updated: September 11, 2026

1. Introduction

This Privacy Policy explains how Unlayered 3D, Inc. (“Unlayered 3D,” “we,” “our,” or “us”) collects, uses, discloses, stores, and protects personal information when you visit www.unlayered3d.com, create or use an account, use Unlayered Universe, apply for access or opportunities, use restricted pilot/customer resources, sign agreements, contact us, schedule meetings, or purchase products or services (collectively, the “Services”).

This Privacy Policy should be read together with our Terms of Use, Cookie Policy, and any service-specific terms presented to you.

2. Information We Collect

A. Account and Identity Information

When you create or use an account, we may collect or maintain:

  • name;
  • email address;
  • account identifier;
  • account creation date;
  • username, bio, avatar, and other profile information, including profile fields that may be created automatically and later edited by you;
  • printers or equipment you choose to associate with your profile;
  • account moderation or posting restrictions; and
  • authentication and session information.

If you sign in with Google, we receive the name and email address made available through the verified Google identity token. We do not request additional Google account scopes through the current sign-in flow.

When an account is created, the current system may automatically generate a default username from the portion of the account email address before the “@” symbol, after removing or adjusting certain characters and, where necessary, adding characters or a number to create an available username. The username can be changed. If you later activate a public Unlayered Universe profile before changing that username, the generated username may be displayed publicly.

The current system may also assign a default profile image from a small set of stock images. A default profile image is not a photograph supplied by you and may be changed through available profile controls. Source credits for Company-provided stock profile images may be listed on the Company’s Credits page.

We may use one-time email login codes. The current system stores a cryptographic hash of the code, attempt information, and expiration data for a short period; the plaintext login code is used only long enough to send it to you.

B. Age and Eligibility Information

The Services are not available to children under 13. During Universe onboarding, we may request your date of birth to determine whether you satisfy the age requirements for an account and for particular features.

The current onboarding system does not retain the raw date of birth after eligibility is calculated. Instead, it retains an age-eligibility date derived from the date of birth (for example, the date on which the user turns 18) and uses that information to determine whether the account is currently a minor account. Because an age-eligibility date can reveal information about a person’s birthday, we treat it as age-related personal information.

Users ages 13 through 17 may browse and download public Unlayered Universe content but cannot upload, comment, vote, or otherwise contribute public user-generated content. Users must be at least 18 to upload or publish Universe content.

C. Unlayered Universe Profile and Community Information

If you use Unlayered Universe, we may collect or maintain:

  • username, bio, avatar, and public profile information;
  • models, 3MF, G-code, STL, STEP, ZIP, and other files you upload;
  • listing titles, descriptions, printer information, print type, and related metadata;
  • images and thumbnails;
  • source credit, authorship information, selected license, and license URL;
  • whether you indicate that AI was used in creation;
  • terms/content-rule/privacy-policy version information associated with uploads;
  • authorship identifiers and creator name associated with a listing;
  • votes and the account identifiers associated with votes;
  • comments, comment author information, and timestamps;
  • download counts and other aggregate activity information; and
  • moderation records.

Having an Unlayered 3D account, hardware order, customer-access record, or software access does not by itself make your profile visible on Unlayered Universe. Universe activation requires a separate affirmative onboarding step, which may include providing age information used to compute an age-eligibility date and accepting the Unlayered Universe Terms of Service. Only after Universe is activated may profile fields designated as public, listings, images, authorship information, comments, vote-related community activity, and other information you choose to publish become visible to other users or the public according to the functionality of the Service.

D. Uploaded File Metadata

Model and print files may contain embedded metadata created by your slicer, CAD software, printer, operating system, or other tools. The current upload system does not automatically inspect or strip all embedded metadata from model or G-code files before storage or publication.

You are responsible for reviewing files and removing personal, confidential, proprietary, or other information that you do not intend to submit or publish.

E. Applications, Forms, and Communications

When you submit an application, contact form, sales inquiry, support request, or other form, we may collect information such as:

  • timestamp;
  • name and email address;
  • company or organization;
  • role;
  • location or geographic information you type into a free-text field;
  • interests;
  • intended use case;
  • whether you request account creation; and
  • any other information you include in a free-text field or message.

Because some fields are free text, please do not submit sensitive or confidential information unless it is necessary and you are authorized to provide it.

F. Pilot and Sales Account Information

For selected pilot or sales customers, we may maintain records such as:

  • customer identifier, name, and email;
  • order type;
  • order or production status;
  • payment-session identifier and payment-cleared timestamp; and
  • customer support or transaction-related information.

A hardware/customer order record may also be linked, generally by account email or account identifier, to a separate profile-style account record. That profile record may include a display name, username, bio, printers or equipment, avatar or profile photo, and, if the user later completes Universe onboarding, Universe eligibility/onboarding information. The customer-facing profile record is distinct from the Company-administered order/payment record. Linking these records does not by itself make the profile public on Unlayered Universe.

Payment checkout is generally hosted by third-party payment processors. We do not directly store complete payment card numbers or card security codes in the Website application.

G. Agreement and Signature Records

When you electronically sign an agreement through the Services, we may retain the name typed into the signature field, the time of signature, the relevant account/customer identifier, agreement/version information where implemented, and an audit record sent through our transactional email provider.

H. Technical, Security, and Network Information

When you use the Services, we may process technical information such as:

  • IP address;
  • approximate country or region derived from IP or edge-network geolocation;
  • browser, device, and operating-system information where available;
  • pages or features accessed;
  • timestamps and general usage information;
  • session identifiers;
  • authentication events;
  • rate-limit information; and
  • security, fraud, abuse, proxy, VPN, Tor, or anonymization signals.

For rate limiting, the current system may temporarily use IP address and, for login-related limits, submitted email address. Rate-limit counters are designed to exist only for a short sliding window.

For Unlayered Universe geographic and network access controls, country information may be derived through Vercel’s edge geolocation. We may send a visitor’s IP address to IPQualityScore or a similar security provider to evaluate VPN, proxy, Tor, fraud, or abuse signals.

3. How We Use Information

We may use personal information to:

  • create, authenticate, secure, and administer accounts;
  • enforce age-based eligibility and feature restrictions;
  • operate Unlayered Universe and associate content, comments, votes, and profiles with accounts;
  • provide model hosting, downloads, and community features;
  • administer pilot/customer access;
  • process and verify purchases and payment status;
  • maintain signature and agreement records;
  • respond to inquiries, applications, sales requests, and support requests;
  • provide transactional emails and login codes;
  • schedule meetings or demonstrations;
  • operate, maintain, debug, protect, and improve the Services;
  • detect fraud, abuse, scraping, bots, unauthorized automated access, security threats, and attempts to circumvent geographic or age restrictions;
  • enforce our Terms, content rules, licenses, and legal rights;
  • comply with legal, export-control, sanctions, and regulatory obligations;
  • send product, company, event, promotional, or marketing communications where permitted by law and subject to applicable opt-out rights; and
  • create aggregate statistics and understand how the Services are used.

4. Universe Content, AI/CAD Development, and Derived Data

Universe Content is subject to the Unlayered Universe Terms of Service. Under those terms, users who upload content grant the Company rights to use uploaded content and resulting print data or prints for research, development, training, testing, evaluation, and improvement of AI, CAD, slicing, software, manufacturing, and hardware systems, and for related dataset and product development.

The Company may also create and commercialize aggregated, transformed, annotated, or otherwise derived datasets and materials as described in the Universe Terms. We do not sell or license a user’s identifiable raw account information, private messages, or identifiable raw submissions as a standalone personal-data product. This does not limit public access to content that a user has published to Universe under the license selected by that user, or the Company’s rights in trained models, derived datasets, analytics, physical test results, or other derived materials under the Universe Terms.

Different data-use rules may apply to other Company products or services if separate terms are presented for those products or services. Unless separate terms say otherwise, the Universe content-development license does not automatically apply to private customer content submitted under a separately executed agreement.

5. Cookies and Similar Technologies

We use cookies and similar technologies for authentication, consent-state management, preferences, security, and analytics as described in our Cookie Policy.

The current Website uses Vercel Analytics only after the applicable analytics consent is accepted. We do not currently use advertising cookies or cross-context behavioral advertising technologies on the Website.

6. How We Disclose Information

We may disclose information to service providers and other parties when reasonably necessary to operate the Services, including providers for:

  • website hosting and edge services, including Vercel;
  • file storage, including Vercel Blob;
  • application data and rate-limiting infrastructure, including Upstash Redis;
  • analytics, including Vercel Analytics;
  • authentication, including Google Identity;
  • transactional email, including Resend;
  • application/form processing, including Google Sheets;
  • scheduling, including Calendly;
  • payment processing, including Stripe and, where used, PayPal;
  • shipping and logistics;
  • fraud, VPN/proxy/Tor, network, and abuse detection, including IPQualityScore;
  • professional services such as legal, accounting, insurance, and security; and
  • business transactions such as a financing, merger, acquisition, reorganization, or sale of assets.

We may also disclose information when required by law, legal process, or governmental request; to protect users, the public, the Company, or others; to investigate fraud or abuse; or to enforce our agreements and rights.

7. Public Information

Information you publish through Unlayered Universe may be accessible to other users or the public. This can include usernames, bios, avatars, listings, images, model metadata, creator/source information, selected licenses, comments, and other community activity made public by the Service. Merely having an Unlayered 3D account, hardware/customer access, or software access does not make those profile fields public; public Universe visibility begins only after the separate Universe activation/onboarding step.

Do not publish information that you want to remain confidential. Removing content from Universe does not guarantee that copies previously downloaded by other users will be deleted, and some user-selected public licenses may be irrevocable according to their terms.

8. Data Retention

We retain information for as long as reasonably necessary for the purposes described in this Policy, including account operation, content hosting, security, support, business records, legal compliance, dispute resolution, and enforcement of agreements.

Retention periods vary by category. For example, login codes and rate-limit records are designed to expire quickly; account information may remain while an account is active; transactional and agreement records may be retained for business and legal purposes; and public content may remain until removed by the user or Company, subject to backups, legal holds, prior downloads, and rights that survive removal under applicable service terms.

Derived datasets, model improvements, aggregate analytics, and trained-model outputs may be retained after the underlying Universe content is removed where permitted by the Universe Terms and applicable law.

9. Security

We use reasonable administrative, technical, and organizational safeguards designed to protect personal information. Current measures include server-side authentication checks, HMAC-signed session identifiers, short-lived login codes stored in hashed form, access controls for private model-file storage, rate limiting, and other security controls. Universe model and G-code files are currently stored in private object storage and delivered through controlled links after authorization checks; thumbnails and avatars may be stored at publicly accessible URLs because they are intended for public display.

No system is completely secure, and we cannot guarantee absolute security.

10. Your Choices and Privacy Rights

Depending on your location and applicable law, you may have rights to request access to, correction of, deletion of, or a copy of certain personal information, and to appeal certain privacy decisions or exercise other rights available under applicable law.

You may opt out of marketing emails using the unsubscribe mechanism provided in the message or by contacting us. Transactional, security, account, and service-related communications may continue even after you opt out of marketing.

If we begin using personal information for targeted advertising or a legally defined “sale” or “sharing” of personal information that requires an opt-out mechanism, we will provide the notices and choices required by applicable law.

To submit a privacy request, contact info@unlayered3d.com. We may need to verify your identity before fulfilling certain requests.

11. Children and Teen Users

The Services are not directed to children under 13, and users under 13 may not create an account. If we learn that we have collected personal information from a child under 13 in violation of applicable law, we will take reasonable steps to delete or otherwise address that information.

Users ages 13 through 17 may have read-only access to Unlayered Universe but cannot upload, comment, vote, or contribute public user-generated content. We may change or further restrict features available to minors for safety, legal, or operational reasons.

12. International Users and Geographic Restrictions

Unlayered 3D is based in the United States. If you access the Services from another country, information may be processed or stored in the United States and other locations where our service providers operate, subject to applicable law.

Some Services may be unavailable from particular countries, territories, VPNs, proxies, Tor exit nodes, or networks. We may use IP-derived country and network-risk information to enforce these restrictions.

13. Changes to This Policy

We may update this Privacy Policy from time to time. We will update the “Last Updated” date when changes are posted. Material changes will apply prospectively, and where applicable law requires affirmative consent to a new use of personal information, we will request that consent before applying the new use.
