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, and any insurance certificate you add, is sent to Anthropic to be read. The "help stop committees being overcharged" box is ticked when the page opens. If you leave it ticked, we keep a private copy of the files and the result, and they become part of the checker's own pricing records, which belong to committeehandbooks.com. We use them to improve the checker and to build pricing information about Australian trade work, such as typical prices by job type, state and year. We never publish or sell an individual quote. We may publish or share pricing figures built from many quotes, with names and contact details taken out. If you untick 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.

The site remembers which state you picked, in your own browser only, so the next page opens on it.
