Frequently Asked Questions
How does Elfbox protect my medical and psychological privacy?
We believe psychological profiles must never be tracked or sold. In Anonymous Mode, you access your account using 12 secret words. No email, name, or personal tracking is ever required.
Can I use Elfbox for couples therapy or workplace team dynamics?
Yes! The Couple Compatibility Engine was designed specifically to bridge different communication and thinking styles (e.g. between different cognitive rhythms, or two divergent attachment styles). The Shared Operating Manual gives practical protocols for avoiding routine clashes.
Are the test results a formal clinical diagnosis?
Elfbox assessments are validated psychometric screening tools and self-exploration frameworks. They provide rich mathematical profiles and actionable operating manuals, but do not replace a formal neuropsychological assessment by a licensed clinician.
