What happens to an uploaded list. Scoring runs in your browser. Your supplier list — including annual spend — is not sent to our servers when you use the tool anonymously. If you sign in and save a list, it is stored under your account and readable only by you.
Sanctions screening. To screen against sanctions/UFLPA lists, supplier names and countries (never spend) are sent to our matching service, processed in memory, and not stored.
Spend data is never public. Annual spend is private tenant data. It is never displayed publicly, shared with other users, or used for anything other than computing your scores.
Account data. If you sign in, we store your email address for authentication and product updates about your saved lists. We do not sell personal data.
Third-party data. Risk reference values come from public sources (Transparency International, ITUC, Yale EPI, World Bank); sanctions data comes from OpenSanctions. Match results are a screening aid, not a legal determination.
