01

Why YAJI exists

Orthodontic change is gradual. Scattered photos and memory rarely form a useful timeline. YAJI makes personal documentation lightweight, private, and easier to maintain over time.

02

Privacy is part of the architecture

Core records stay on your iPhone. No YAJI account is required and the current version does not connect to a YAJI server. It includes no advertising, third-party analytics, or cross-app tracking.

03

A record, not a verdict

YAJI organizes photos, tags, notes, degree readings, and dates. It does not diagnose, assess treatment results, recommend care, or publish normal ranges. Treatment decisions belong between you and a qualified clinician.

04

Built and operated by

YAJI is developed and operated by 隆阳区藻峙软件开发工作室. We aim to maintain a restrained, clear, and dependable personal journal for the long term.

From standardized capture to visit preparation, YAJI is designed around the real moments of an orthodontic journey.
