We don't store your free-scan code. It's sent over encrypted TLS to our servers for scoring (including our AI provider), then discarded — we keep only your score and risk profile, never the code. GitHub import fetches only the files you select. If you upgrade to Interactive Code Review, your selection stays in this tab until review begins.
What we keep Your score and risk profile only (domain, §101 level, AI contribution level). Used to alert you if the law changes.
Did you use AI to help write this code?

Optional — sharpens human-contribution scoring. Not forensic proof; practical guidance on inventorship when AI helped.
