Koutei Systems ("we", "our", "us") operates the Koutei PDF service. This Privacy Policy explains how we collect, use, and protect your information when you use our PDF and image generation platform.

2. Information We Collect

Account Information: When you sign up, we collect your email address and, if you use Google OAuth, your Google profile information (name and email). Authentication is handled by Supabase Auth.

Usage Data: We track your credit usage, API key creation, and generation history to provide the service and enforce usage limits.

Payment Information: Payment processing is handled by Paystack. We do not store your credit card or bank details. Paystack's privacy policy governs how your payment data is processed.

Document Data: Template variables and data you submit for PDF/image generation are processed in real-time and are not stored after generation completes.

We use the following third-party services to operate our platform:

  • Supabase — authentication and database hosting
  • Vercel — frontend hosting and analytics
  • Railway — backend engine hosting

Each of these services has its own privacy policy governing data processing.
