Welcome to ConstraintCraft Project Cards ("ConstraintCraft", "we", "our", or "us"). This Privacy Policy explains our practices regarding the collection, storage, and safeguarding of information when you interact with our constraint-based 3D modeling task cards, educational workflows, CAD challenge generators, and web applications.

By accessing or utilizing our website, platforms, downloadable constraint decks, or associated educational resources, you acknowledge the terms established in this Privacy Policy. If you do not agree with our principles and practices, please discontinue use of our site.

We gather minimal data necessary to maintain system performance, deliver educational prompt cards, and enhance CAD instruction tools:

We do not collect sensitive demographic details, financial transaction credentials, or confidential proprietary CAD model source files on public pages.

Information collected is strictly applied toward pedagogical utility and platform optimization:

• Curriculum Delivery: Providing responsive CAD challenge generators, sorting maker cards by difficulty level, and maintaining platform responsiveness.
• User Support: Responding promptly to maker inquiries, workshop implementation requests, and classroom curriculum questions.
• Security & Integrity: Detecting malicious automated scrapers, ensuring network uptime, and protecting platform assets from unauthorized disruption.
• Educational Insights: Evaluating aggregated usage trends to create more effective dimensional constraints and beginner-to-advanced CAD exercises.

Our platform employs standard browser cookies and local storage tokens to preserve user preferences (such as dark mode settings, card filter states, and active difficulty tabs) without requiring persistent authentication.

You can adjust your browser settings to decline or clear cookies at any time; however, some interactive filter configurations may revert to standard defaults upon refresh.

We may integrate trusted third-party providers strictly for delivery optimization, typography rendering, and basic web traffic auditing:

• Content Delivery Networks: Fast loading of fonts, icons, and framework scripts via global CDN nodes (e.g., Google Fonts, CDNJS, jsDelivr).
• Privacy-Preserving Analytics: Aggregated measurement tools that do not deploy tracking beacons or cross-site fingerprinting.

We do not authorize third-party vendors to utilize your information for independent advertising, retargeting campaigns, or profile building.

Regardless of geographic location, we respect user autonomy over personal information. Under applicable regulations (such as GDPR and CCPA), you hold the following rights:
