Privacy, in plain words

Sparkship is in a small, invite-only test. This is what we keep, why, and what you can do about it.

What we keep

• Your email address, to sign you in (no passwords).
• Your projects: what you asked for, the conversation with the builder, and every saved version of your app.
• Replies people send through forms on your apps, so you can read them.
• Files you attach in the chat (pictures, PDFs, documents), in your project’s workshop, so the builder can read them. They are never published unless you ask for a picture to be on your page.
• How many requests you make to the builder and what they cost us, to keep the test affordable.
• Anything you send us with the Feedback button.
• If you ask for an invitation on our front page: your name, your email and what you’d like to create, until we answer. Then we delete the request.

Who else sees it

We use a few trusted services to run Sparkship: Vercel (hosting, in Frankfurt), Neon (our database, in Frankfurt), Anthropic (the AI that builds your apps; it sees your requests, the files you attach and your app, not your email) and Resend (sign-in emails). We never sell your data and never use it for advertising.

Your choices

You can delete your account and everything in it at any time on your account page. Your published apps are taken off the internet at the same moment. Questions? Use the Feedback button or write to the person who invited you.
