What is sent to AI, and when?

Only when a feature that reads something runs, and only what it needs: a CV when it's read, a screening call or video interview when it's analysed, your website when you match its look, and a job description when you ask for draft questions, a question you type into Ask Masthead, and the week's activity for organisational memory. Masthead uses Claude, by Anthropic, for reading and analysis.
