Honest limits

FootprintIQ uses Open-Source Intelligence (OSINT) on public data only. We never bypass authentication, scrape behind logins, or access private accounts. Every result includes a confidence score so you can tell verified matches from likely matches that need human review. Use FootprintIQ for self-audit, authorised investigations, or compliance research — not for harassment, doxxing, or surveillance.
