Coverage and interpretation
Local metadata only: no external request, call or SMS. Does not verify a subscriber, carrier, active line or physical location. Non-geographic and ambiguous countries remain undetermined. Metadata has a recorded version and may age.
Public observations are not proof of real-world identity. Review candidate records against their cited sources. Saved investigations preserve evidence acquisition times and provider provenance; these timestamps do not establish when a profile or fact first existed.
