Kincaid Personal Assistant is a private app. Its owner is its only user.
The app has read-only access to the owner's Gmail, granted by the owner. It reads the sender, subject and a short preview of recent unread email to answer the owner's questions. It cannot send, change or delete email.
Email details are sent to the AI service that powers the assistant so it can answer. Data is not sold, is not used for advertising, and is not shared with anyone else.
The app stores the owner's conversations with the assistant on a private server. It does not store full email text. The owner can delete stored conversations at any time, and can remove the app's Gmail access at any time from their Google Account.
