Each purchase's terms, including refunds, are the ones Gumroad shows you at checkout: legal notice.
Our software never sends your trades or your accounts to any server: it only sends your license key to Gumroad to check it (Prop Firm Lab at most once every 3 days, NT8-MCP Pro at most once a week). If you connect NT8-MCP to a cloud AI, what you ask it and what it reads from your accounts does go to that AI.
