1. Information We Collect

When you use Nebula, we may collect the following types of information:

  • Account Information: If you sign in via Google or GitHub, we receive your name, email address, and profile picture from those providers.
  • Generated Prompts: Prompts you generate are stored privately and associated with your account. Prompts you contribute to the community are stored publicly.
  • Uploaded Images: Reference images you upload are sent to Cloudinary for hosting and to our AI model for analysis. Images attached to community contributions are stored persistently.
  • Usage Data: Standard server logs including IP addresses, browser type, and pages visited, retained for up to 90 days.

2. How We Use Your Information

  • To provide and improve the Nebula AI prompt generation service
  • To sync your private prompt history across devices (signed-in users only)
  • To display your community contributions to other Nebula users
