Privacy Policy

1. Data Collection

3DMold (the "App") only collects the 3D model files (STL format) that you actively upload for geometry calculation services. We do not collect your name, phone number, physical address, or any other sensitive personal information.

We collect an anonymous User ID solely to verify your subscription status and link your cloud calculation tasks. Additionally, metadata related to the 3D content associated with your account (Other User Content) may be processed to ensure proper content delivery and App functionality. This data is linked to your account for functional purposes only and is not used for tracking or third-party marketing.

2. Data Processing & Retention Strategy

● Upload Phase

The original 3D models uploaded by users are used exclusively for cloud-based mold generation. Once the calculation task begins, the original model is removed from the processing pipeline.

● Storage Phase

The generated mold results are temporarily stored in a protected cloud storage (Cloudflare R2), accessible only by the user via the App.

● Automatic Destruction (Burn-After-Reading)

- Immediately after the user completes the download, the system marks the file for deletion.
- If not downloaded within 24 hours, the system performs an automated cleanup task to physically delete the file and permanently invalidate the download link.

● No Other Use

We strictly protect your intellectual property. We do not use uploaded models for AI training, secondary distribution, or any form of persistent retention.

3. Third-Party Services

To provide global network distribution and high-performance computing, we use the following trusted third-party services:

Cloudflare: Used for global network acceleration (Workers) and object storage (R2).
DigitalOcean / Ubuntu: Used for deploying our high-performance geometry engine.

These providers act strictly as infrastructure suppliers and have no access to your model content.

4. Your Rights

Since we do not collect personally identifiable information (PII), there is no requirement for account deletion. You can terminate the service at any time by deleting the App. If you have any questions regarding data security, please contact us via the Support page.
