These terms cover your use of Book Builder, operated by [LEGAL ENTITY], [ADDRESS]. Creating an account means you accept them.
Book Builder reads material you upload, interviews you, and writes and typesets a book from what it finds. Paid plans let you export the finished book as a file.
You need a working email address, and you're responsible for what happens under your login. One account is for one person; don't share credentials. You must be old enough to enter a contract where you live.
You keep ownership of everything you upload. You confirm you have the right to use that material — don't upload someone else's work you have no licence to, and don't upload personal data about other people that you aren't entitled to process.
You grant us only the permission needed to run the service for you: to store your material, and to pass it to the AI providers listed in the privacy page so your book can be written. Nothing more.
The book is yours. Use it, sell it, print it, publish it — no royalty is owed to us.
Two honest limits. AI writing can be wrong, and it can produce passages resembling text it was trained on: read what it writes before you put your name on it. And identical prompts can produce similar output for different users, so we can't promise your text is unique.
Don't use Book Builder to produce material that is illegal, that harasses or defames someone, or that infringes copyright. Don't try to break, overload or reverse-engineer the service, and don't resell access to it. Accounts doing these things can be suspended.
Paid plans are billed in advance through Stripe, monthly or yearly, and renew automatically until cancelled. Cancel any time from the billing page; your plan then runs to the end of the period you've paid for and stops. Prices may change, but never for a period you have already paid.
If something goes genuinely wrong — the service didn't work and you couldn't use what you paid for — write to [CONTACT EMAIL] and we'll sort out a refund. Consumers in the EU have a statutory right of withdrawal; note that by starting to generate a book during that period, you ask us to begin the service immediately.
Plan limits are counted in pages per calendar month and per book. Where a request exceeds a limit, the service tells you rather than charging you more.
We aim to keep the service running and your work safe, but it is provided as-is: no promise of uninterrupted availability, and no guarantee against loss. Keep your own copy of anything you can't afford to lose — on a paid plan, export it.
To the extent the law allows, our liability for any claim connected to the service is limited to what you paid us in the twelve months before it arose. Nothing here limits liability for death, personal injury, fraud, or anything else that cannot legally be limited — including consumers' mandatory rights.
You can stop and ask for deletion at any time (see the privacy page). We may suspend or close an account that breaks these terms, and will say why unless prevented by law.
If these terms change materially you'll be told before the change takes effect. They are governed by the law of [JURISDICTION], with the courts of [JURISDICTION] competent — without depriving a consumer of the protection of their home country's mandatory law.
