This page explains what kdpbookai stores about you, why, and how to get a copy or delete it.

What we store

  • Your Google sign-in: email address, name and profile picture.
  • Your books: settings, text, pictures, covers, listings and the planning chat.
  • Photos you upload to guide a character drawing.
  • Your character library and series.
  • Credits you received and spent, payments and your subscription. We never see your card number.
  • Sign-in sessions with the browser name, so you can see and end them in Settings.
  • Signals to stop people opening many free accounts: a keyed hash of your network (not your full address), a device cookie and your Google account id.

Why

  • To make and store your books, which is the service you asked for.
  • To charge for paid steps and keep accounting records.
  • To keep the service safe: stop abuse, block content that breaks our content policy and fix errors.

Who helps us

These companies process data for us, only to run the service:

  • Google Firebase: sign-in.
  • OpenRouter and the AI model providers it routes to: your book text, prompts and reference pictures are sent to make text and pictures.
  • Cloudflare R2: file storage for pictures and print files.
  • Lemon Squeezy: payments, taxes and invoices.
  • Resend: emails we send you.
  • Sentry: error reports, which may include the page you were on.

How long we keep it

  • Books, pictures and photos: until you delete them. Deleted books and pictures are removed from storage after a grace period of about 30 days.
  • Sign-in sessions: 30 days from your last visit.
  • Abuse signals: 365 days.
  • Payment and credit records: as long as tax law asks, without your name or email after you delete your account.

Your choices

  • Download all your data as a file: Settings, Account, Download my data.
  • Delete your account: Settings, Account, Delete account. Your books, pictures, characters, series and profile are deleted.
  • Ask us anything about your data by email.

Photos of people

Upload a photo only if you took it or have the right to use it. For a photo of a child you must be their parent or guardian or have their permission. The photo only guides the drawing and is deleted with the book or your account.
