Last updated: 2026-10-12

1. Introduction

Bulin 47 AI Video ("we", "us", or "our") respects your privacy. This Privacy Policy outlines how we collect, store, and process your information when you use our website, upload portrait photos, generate AI videos, and manage your credits.

By accessing or using our services, you acknowledge that you have read and understood this Privacy Policy.

2. Information We Collect

  1. Account Details — When you sign up or log in, we collect your name, email address, and authentication identifiers through our secure authentication providers.
  2. Uploaded Portrait Photos — When you generate a video, you upload a portrait photo (JPG, PNG, or WebP format, up to 15MB).
  3. Generated Videos — We temporarily host and deliver the resulting 15-second MP4 video files generated by our AI pipeline.
  4. Credit & Transaction Records — We record your credit allocations, deductions per video resolution, and refund history. Payment card details are processed directly by our payment processor and are never stored on our servers.
  5. Technical Logs — We collect standard technical telemetry (IP address, browser type, timestamps) necessary for rate limiting, system diagnostics, and security monitoring.

3. How We Process and Store Your Data

  • AI Model Processing — Uploaded images are transmitted securely to our AI compute partner (KIE WAN 3.0 API) solely for the purpose of executing the requested video generation task.
  • Storage Infrastructure — Uploaded photos and rendered video outputs are stored securely in Cloudflare R2 object storage to enable video preview and MP4 downloading. Self-service deletion is currently not automated; you may request deletion of your uploaded photos and generated videos by contacting support.
  • No Model Training on User Photos — We do not use your personal portrait uploads to train or fine-tune public foundation AI models without your explicit consent.
  • Likeness Protection — We require all users to confirm that uploaded photos portray themselves or an adult with explicit permission. Uploads of minors or unauthorized public figures are strictly prohibited.

4. Third-Party Service Providers

We utilize trusted enterprise infrastructure providers to deliver our service:

  • Cloudflare — DNS, edge routing, Workers compute, and R2 object storage.
  • KIE — Generative AI compute infrastructure for WAN 3.0 video synthesis.
  • Payment Gateways — PCI-compliant third-party payment processing.
