Privacy Policy, Terms of Service & Liability Disclaimers

1. Introduction & Scope

Welcome to Brickmine3D (accessible at https://brickmine3d.jrpcrewlabs.com and its subdomains), operated by JRPCrew Labs ("we", "our", or "us").

This Privacy Policy clearly articulates our commitments regarding data collection, processing, user rights, and privacy protections when you interact with our WebGL 3D CAD rendering engine, web studio, and identity services. We operate under strict zero-knowledge data retention principles for all user-uploaded 3D assets.

2. Information We Collect

We only collect the minimum personal data strictly necessary to provide authentic creator access and cloud wallet protection:

• Account Identity Information: When you register or sign in via email or Google OAuth 2.0, we collect your email address, profile display name, and avatar image URL.
• Authentication & Security Telemetry: Session authentication tokens, multi-factor authentication (TOTP) metadata, and standard web server logs (IP address, user agent) to protect your account against unauthorized access or abuse.
• Wallet Ledger Data: Record of free starter credit allocation and transactional deduction history for 4K renders.

What We Do NOT Collect: We do NOT collect payment card numbers, billing addresses, or banking information (all transactions are routed directly via PCI-DSS compliant payment gateways). We do NOT collect biometric data, physical location telemetry, or personal browsing activity outside our application.

3. Zero Cloud File Retention for 3D CAD Models

Your proprietary 3D CAD models are never stored on our servers.

When you import 3D files (including .io, .ldr, .mpd, .glb, or .stl), all camera staging, geometry parsing, Three.js shader rendering, and 4K media encoding occur ephemerally in client-side WebGL session memory within your browser. Once your browser tab is refreshed or closed, all in-memory CAD models and synthesized video frames are permanently erased.

4. Compliance with Google API Services User Data Policy

Brickmine3D utilizes Google OAuth 2.0 to offer a safe, one-click sign-in mechanism. We request access exclusively to basic, non-sensitive identity scopes (email, profile, and openid).

Limited Use Disclosure: Brickmine3D's use and transfer of information received from Google APIs to any other app will adhere to the Google API Services User Data Policy, including the Limited Use requirements.

We do not sell Google user data to third parties, nor do we utilize Google user data for advertising, data brokering, or training third-party machine learning models without your explicit consent.

5. Strict Zero Data Sharing & No-Sale Guarantee

We do not sell, rent, monetize, or share your personal data with any third party. Ever.

• Zero Advertising & Data Brokering: We do not partner with ad networks, data brokers, advertising cookies, or behavioral trackers. We will never sell, lease, or monetize your email address, identity data, or usage logs.
• Zero AI Model Training on User CAD Assets: We never harvest, inspect, store, or feed user-uploaded 3D models, MOC designs, or custom geometry into machine learning or generative AI training datasets. All AI research at JRPCrew Labs is trained strictly on open-source, public domain assets.
• No Cross-Site Tracking: We do not utilize third-party tracking pixels (such as Meta Pixel, TikTok Pixel, or Google Ads remarketing) or cross-site fingerprinting scripts.
• Confidential Infrastructure Partners Only: Data is processed strictly by our SOC-2 / ISO-27001 compliant technical infrastructure providers (Supabase, Resend, Cloudflare, Vercel) solely to run the platform under strict data protection agreements. None of these partners have authorization to access, utilize, or resell your data for independent purposes.

6. Third-Party Infrastructure Processors

To deliver a resilient, high-speed cloud platform, we collaborate with industry-standard, SOC-2 compliant infrastructure providers strictly for computational delivery:

• Supabase Inc.: Encrypted PostgreSQL database hosting, Row Level Security (RLS) enforcement, and authentication tokens.
• Resend / Cloudflare: Transactional email verification and edge DNS resolution (SPF, DKIM, and DMARC enforcement).
• Cloudflare Inc. (R2 Storage): Static LDraw geometry CDN distribution ($0 egress, public part library assets only; no user models).
• Vercel Inc.: Production web hosting and edge content distribution.

7. User Rights, GDPR & CCPA/CPRA Compliance

Regardless of your geographic location, you retain full rights over your personal data:

• Right to Access & Portability: View your active wallet balance, transaction ledger, and email profile at any time in the Studio settings.
• Right to Self-Service Erasure ("Right to be Forgotten"): We provide an automated in-app deletion mechanism. In the Studio under Account Settings → Danger Zone, you can instantly and permanently purge your account, profile, authentication credentials, and ledger records.
• California Residents (CCPA / CPRA): We do not sell or share personal information as defined by California law. Because no data selling or sharing occurs, an opt-out mechanism is unnecessary.
• Right to Non-Discrimination: You will never be denied equal service, subjected to altered pricing, or penalized for exercising your statutory privacy rights.

8. Cookies & Client-Side Local Storage

Brickmine3D does not use tracking, marketing, or third-party advertising cookies. We exclusively use strictly necessary browser localStorage keys (such as authentication session tokens and client-side UI preference flags) to keep your 3D studio session active and maintain your selected camera settings.

9. Children's Privacy

Brickmine3D is designed for hobbyist creators, engineers, and digital builders. We do not knowingly collect or solicit personal information from children under the age of 13. If we learn that we have collected personal data from a child under 13, we will promptly delete that information from our database.

10. Independent Utility & Non-Affiliation Disclaimer

Brickmine3D and JRPCrew Labs are 100% independent software utilities and are NOT affiliated with, endorsed by, authorized by, or sponsored by any brick, toy, or gaming manufacturer.

All references to third-party file extensions or standards (such as .io, .ldr, .mpd, .dat, .glb, or .stl) are strictly descriptive of technical file-format compatibility. LEGO® and BrickLink® are trademarks of the LEGO Group of companies, which does not sponsor, authorize, or endorse this site or software. Hasbro®, Mega Bloks®, and Minecraft® / Mojang® are trademarks of their respective owners.

11. User-Generated Content (UGC), IP Responsibility & Indemnification

Brickmine3D operates strictly as a passive, client-side in-browser rendering utility—analogous to a local camera or graphics renderer running on your own device:

• Creator Ownership & Zero Platform Royalties: You retain 100% of whatever rights you hold in the 3D models you load into your browser session and the 4K stills or 60FPS videos you export. JRPCrew Labs claims zero ownership and charges $0 in royalties on your exported renders.
• Sole User Responsibility for Uploaded Models: You represent and warrant that you have the lawful right or permission to load, render, and export any 3D CAD file you process through the Studio. Because rendering executes locally in your browser's WebGL memory with zero server retention, JRPCrew Labs does not pre-screen, host, or distribute user-uploaded files.
• Indemnification: By using Brickmine3D, you agree to indemnify, defend, and hold harmless JRPCrew Labs, its founders, operators, and affiliates from and against any third-party claims, demands, liabilities, damages, or expenses (including legal fees) arising out of or related to any 3D models, designs, intellectual property, or media that you upload, render, export, publish, or commercially distribute.

12. Open-Source, Community Benchmark Models & Third-Party Format Attribution

Brickmine3D gratefully acknowledges the open-source communities and public CAD repositories whose permissive standards make browser-based 3D CAD visualization possible:

• LDraw™ Parts Library: Brickmine3D utilizes the LDraw Parts Library (ldraw.org) under the Creative Commons Attribution License (CC BY 2.0 / CC BY 4.0). LDraw™ is a trademark owned and licensed by the Estate of James Jessiman.
• Three.js WebGL Engine: Client-side 3D rendering is powered by Three.js under the permissive MIT License.
• Preloaded Community Demo & Benchmark Models (Illustration Only — Not for Distribution): Sample 3D models and visual comparison benchmarks displayed in the Studio viewport and Spatial AI preview gallery are sourced from publicly available open-source LDraw Official Model Repository (OMR) archives, public BrickLink Studio community shares, and open European/global 3D brick CAD benchmark repositories strictly and solely to illustrate the 3D rendering, lighting, and shader capabilities of the platform. These demo models are strictly NOT for distribution, cannot be downloaded or exported, and are technically export-locked in the Studio software. JRPCrew Labs does not sell, license, charge credits for, distribute, or provide downloads of community sample CAD files.
• Creator Attribution & 24-Hour Courtesy Removal Policy: We deeply respect the AFOL and MOC creator community. Any original model designer who wishes to have a direct creator credit/portfolio link displayed alongside a benchmark model—or wishes to have a sample model removed from our demonstration showcase—may contact support@jrpcrewlabs.com for prompt attribution or removal within 24 hours.

13. Digital Render Credits, "As-Is" Warranty & Limitation of Liability

• Digital Credits & Fair-Deduction Guarantee: Studio render credits are one-time digital consumables used to export high-resolution 4K stills and 60FPS turntable videos. Credits never expire while the platform operates, carry no cash value outside the platform, and are non-transferable. Credits are only deducted after a render completes 100% in your browser; zero credits are deducted if a render fails or is interrupted. For any billing assistance, contact billing@jrpcrewlabs.com.
• "AS IS" & "AS AVAILABLE" Disclaimer: Brickmine3D is provided on an "AS IS" and "AS AVAILABLE" basis without warranties of any kind, whether express or implied, including implied warranties of merchantability, fitness for a particular purpose, or non-infringement. Because WebGL performance depends on your local device hardware and browser, we recommend testing your device using the 6 Free Starter Credits provided upon registration before purchasing credit packs.
• Strict Limitation of Liability: To the maximum extent permitted by applicable law, in no event shall JRPCrew Labs or its individual operators be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of profits, data, or goodwill. Our total cumulative liability for any claim arising out of or relating to the platform shall not exceed the total amount (in USD) actually paid by you to JRPCrew Labs during the thirty (30) days immediately preceding the event giving rise to the claim (or $0.00 USD if you have only used free credits).
• Governing Law: These Terms and Privacy Policy shall be governed by and construed in accordance with the laws of the Republic of Singapore, without regard to conflict-of-law principles.
