Xeo Disposition: Big Five

Xeo Disposition is a 120-question Big Five personality inventory that runs entirely on your phone. No accounts. No servers. No tracking. No analytics SDKs. Your answers never leave your device unless you choose to export them.

WHAT IT MEASURES
The Big Five model is the most extensively researched framework in personality psychology. The five traits — Openness, Conscientiousness, Extraversion, Agreeableness, and Neuroticism (OCEAN) — describe broad, stable patterns in how people think, feel, and act.

WHAT YOU GET
• Five-axis radar chart of your trait scores
• Plain-language commentary on each trait
• 30 facet scores (six per trait) for finer detail
• PDF export you can save to Files, AirDrop, email, or print
• Resume support — kill the app, come back, pick up where you left off

PRIVACY POSTURE
• Zero network requests. The app makes no internet connection.
• No analytics, no crash reporters, no advertising frameworks, no third-party SDKs.
• iCloud backup excluded — your answers don't sync across devices. • One Settings → Reset action wipes everything from local storage.
• A plain-language privacy policy is built into the app.

ACADEMIC BASIS
The 120 items are drawn from the International Personality Item Pool (IPIP, ipip.ori.org), placed in the public domain by Lewis Goldberg. The specific 120-item set (IPIP-NEO-120) was developed by John A. Johnson as a public-domain emulation of the proprietary NEO-PI-R; this app uses IPIP wording, not NEO-PI-R wording. The NEO-PI-R items themselves are proprietary to PAR Inc. and are not used in this app. Attribution appears in the in-app About screen.

NOT MEDICAL ADVICE Xeo Disposition is for personal exploration, reflection, and conversation. It is not a clinical instrument, not a diagnosis, and not a substitute for professional psychological assessment.
