The short version
You don't need an account and we don't ask for your name. The books are sold by Amazon, so we never see payment details.
Ask a question
Your questions are sent to an AI service (Anthropic) to write the answer. We don't save your conversation. Please don't type personal details into it.
Quote checker
The quote you upload is sent to Anthropic to be read. If you tick the box to help improve the checker, we keep a private copy of the quote and the result. We use it only to improve the checker's judgement, it is never published, and we don't share it. If you don't tick the box, nothing is kept. Quotes can contain a business's name and contact details, so cover anything you don't want to share before uploading.
Anthropic's handling of data sent through its service is described at anthropic.com/legal/privacy.
Other things
To stop misuse, each visitor has a daily limit, worked out from their internet address. That count is temporary and isn't linked to anything else. The site is hosted by Cloudflare, which keeps standard security logs. Links to other websites, including Amazon, are covered by those sites' own privacy policies.
If you'd like a stored quote removed, tell us the date you uploaded it and the business name on it.
