Most age verification tools force users through ID uploads,
selfies, or identity walls — killing conversion and storing
sensitive data. A3 is different. We use passive signal-based
age estimation across web, iOS, and Android with one API
call. No PII is stored. No friction. Users never leave your
flow. Built for US regulations like AB 1043 and COPPA, A3
keeps you compliant without sacrificing UX or taking on data
liability.
