Acceptance

By accessing or using "Tiangong Box" (互为螺旋·天工匣, the "Site"), you agree to these Terms. If you do not agree, please stop using the Site. The Site is operated by an individual developer; contact: hwdemtv@126.com.

The service

  • The Site offers 3D-printing generator tools that run in your browser: images or parameters are processed locally on your device to produce printable files (perler patterns, charms, molds and more).
  • Some tools are free; others require a membership or credits, as described on each tool page and the purchase page.

Accounts

  • Register with a valid email and keep your password safe. Accounts are for personal use only and may not be sold, lent or transferred.
  • Do not mass-register accounts or farm credits or invite rewards with automation. We may freeze accounts and benefits involved in such abuse.

Membership, credits and refunds

  • Membership and credits are virtual goods delivered instantly upon purchase. Except where required by law or where the Site itself causes the benefits to be unusable, purchases are non-refundable.
  • Membership scope is as described on the purchase page. Tools may be added, changed or retired; members keep full access to whatever tools are available during the membership period.
  • Price changes do not affect completed orders.

User content and copyright

  • You are responsible for what you upload: when using image-to-model tools, make sure you hold the rights (copyright, likeness, etc.) to the images. Disputes arising from infringing uploads are your responsibility.
  • Files you generate and download are yours to use; the Site claims no rights over them.
  • The Site's page design, tutorial articles, tool code and brand assets (including "互为螺旋·天工匣" / Tiangong Box) belong to the Site and may not be copied, republished or used commercially without permission.

Acceptable use

You agree NOT to:

  1. generate, print or distribute files intended for unlawful uses (weapons, counterfeit merchandise, etc.);
  2. scrape, stress-test, inject into, reverse-engineer or otherwise disrupt the service;
  3. use the Site's content or open endpoints for unauthorized automated or commercial purposes.

Disclaimers

  • Print outcomes (strength, material safety, fitness for purpose) depend on your printer, filament and slicer settings — evaluate before printing. Generated files are not intended for safety-critical uses such as medical devices or load-bearing equipment.
  • The Site is provided "as is", without a guarantee of uninterrupted or error-free service. To the maximum extent permitted by law, the Site is not liable for indirect losses arising from your use.
  • We make reasonable efforts to keep the service healthy and to announce planned maintenance in advance.

Changes and termination

  • Updated Terms are published on this page with a new effective date; continued use constitutes acceptance.
  • You may stop using the Site and close your account at any time. We may restrict or terminate access for serious violations of these Terms.

Governing law and disputes

These Terms are governed by the laws of the People's Republic of China. Disputes shall first be resolved amicably; failing that, they shall be submitted to a competent people's court at the operator's location. See also our Privacy Policy.
