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.
