What we collect

• Your GitHub name, email address and profile picture, when you sign in.
• The prompts you write. The images you make are saved to a Prospero folder in your own Google Drive and kept in your browser; we don’t keep a copy. A reference image you add is sent to our image model provider with your prompt and isn’t stored.
• Permission from your Google account to save files to your Drive. It only covers files Prospero creates; we can’t see anything else in your Drive.
• Your IP address, approximate location (country and city) and browser, for each visit, sign-in and image request. We use these to stop abuse, enforce one free trial per person, and keep the service secure.
• If you make free images without signing in, a cookie with a random ID so we can count them. Those images are kept only in your browser.
• Payment status from Dodo Payments. We never see or store your card details.

How we use it

Only to run Prospero: making your images, keeping your balance, preventing abuse and fixing problems. We don’t sell your data or use it for advertising.

Who processes it

GitHub (sign-in), Google (saving your images to your Drive), our image model provider (prompts and images), and Dodo Payments (payments).

Your choices
