Privacy & Data Protection Framework

Privacy Policy

We believe in radical data transparency. As an interactive 3D platform, we collect specific technical and submission data to operate smoothly. This document details precisely what we collect, our lawful basis, and how you can exercise instant erasure.

Need to erase your collected data?GDPR Art. 17 / CCPA

You can immediately wipe local browser caches and submit a verified server purge request with a single click.

1. Identity of Data Controller

The data controller responsible for the processing of user data through NEXUS.3D is the NEXUS Platform Engineering and Data Governance Division. If you have questions about our data collection practices, you may reach our Data Protection Officer (DPO) at dpo@nexus3d.internal.

2. Categories of User Data We Collect

We explicitly inform users whenever data is collected. Below is our comprehensive registry of data categories, purposes, and retention limits:

1. Project Submission Data

Directly Provided
Data Elements Collected
  • Developer / Creator Name
  • Contact Email Address
  • Project Repository & Live Demo URLs
  • Project Architectural Description & Tags
Processing Purpose

To catalog, attribute, and index your 3D software submission in our public showcase.

Retention Period

Retained until developer requests removal via the Data Deletion Portal.

2. 3D WebGL GPU & Performance Telemetry

Automatically Collected
Data Elements Collected
  • Unmasked GPU Vendor & Renderer string
  • Target frame rate (FPS) and frame drop events
  • Canvas resolution & Device Pixel Ratio
  • Shader compilation error logs
Processing Purpose

To dynamically calibrate 3D scene polygon density, avoid browser GPU context loss, and optimize rendering efficiency.

Retention Period

Aggregated anonymously and purged on a 30-day rolling cycle.

3. Session & Interaction State

Client-side Storage (Cookies & LocalStorage)
Data Elements Collected
  • Category filter preferences
  • Cookie consent status
  • 3D Scene visual mode (wireframe/solid/particle speed)
  • Recent project modal inspection events
Processing Purpose

To preserve user interface preferences and prevent re-prompting consent banners.

Retention Period

Persisted in local browser storage; instant wipe supported via One-Click Local Purge.

3. Lawful Basis for Processing (GDPR Art. 6)

A. Explicit Consent

Applies to project submissions, contact emails, and voluntary telemetry tracking. Users may withdraw consent at any time.

B. Legitimate Interests

Applies to anonymous GPU hardware profiling strictly necessary to prevent WebGL browser crashes and optimize shader rendering.

C. Legal Compliance

Applies to retaining verifiable audit proofs of user deletion requests for regulatory transparency.

4. Your Statutory Privacy Rights

Under international privacy regulations (including GDPR Articles 15-22 and the California Consumer Privacy Act), you possess the following actionable rights:

Right to Erasure ("Right to be Forgotten"):

Request the irrevocable deletion of all your submitted records and telemetry.

Right to Access & Portability:

Obtain an exportable machine-readable JSON copy of any stored personal data.

Right to Rectification:

Request correction of inaccurate project details or updated email addresses.

Right to Non-Discrimination:

Full access to 3D showcases is never denied or restricted for exercising privacy rights.

5. Third-Party Sharing & Security Standards

We do not sell user data. We do not engage with third-party data brokers, ad networks, or behavioral cross-site trackers. Infrastructure subprocessors (such as edge content delivery networks) only process data under strict Data Processing Agreements (DPAs) with standard contractual clauses.

All telemetry and submission records are protected with TLS 1.3 in-transit and AES-256 encryption at rest.
