Prompt privacy checklist.

Prompt privacy is not only about secrets. It is about context: names, habits, plans, files, constraints, and fragments that can say more together than they seem to say alone.

1. Remove direct identifiers. Names, addresses, account numbers, ticket references, private URLs, payment details, and internal customer notes rarely need to travel with the whole prompt.

2. Keep the useful shape. Replace personal details with roles, labels, or rough categories when the answer only needs the structure of the problem.

3. Check hidden context. Pasted emails, documents, spreadsheets, screenshots, and transcripts often carry more than the visible question: metadata, side comments, quoted chains, and names from earlier work.

4. Ask what could become memory. If the same detail would feel uncomfortable as a future assumption, it deserves one more look before it is shared.

Ownesis starts from that review moment. The aim is not to make AI harder to use, but to make the boundary easier to see.
