1. Information We Collect

When you create an account, we collect your email address. If you authenticate via third-party providers (Google, Discord, GitHub, X/Twitter), we receive basic profile information (name, email, avatar) as authorized by you through those services.

We collect information about your interactions with the Service, including: text prompts submitted for generation, generation parameters (model, resolution, seed), credit usage and transaction history, and pages visited.

  • NSFW content published from Japan is automatically censored (mosaic) for public display in compliance with Japanese law.

  • You can delete individual generations from your gallery at any time.
  • Upon account deletion, we will remove your personal data within 30 days. Backup copies may persist for up to 90 days.
  • Anonymized, aggregated data (e.g., total generation counts) may be retained indefinitely.

6. Data Security

We implement industry-standard security measures including:

  • TLS encryption for all data in transit
  • Encrypted database connections (Supabase)
  • Row-Level Security (RLS) policies isolating user data
  • API key hashing (SHA-256) for developer tokens
  • Rate limiting and IP-based abuse prevention

While we take reasonable precautions, no system is completely secure. We cannot guarantee absolute security of your data.
