About SecretDiary
SecretDiary is a private journal for iPhone, iPad, and Mac. Write personal notes, daily reflections, travel memories, study logs, or work journals in a calm SwiftUI interface designed for long-term writing.
Your diary stays local on your device. SecretDiary does not upload your diary text or password to external servers. A local password lock helps protect private writing, and the data management tools let you export readable JSON backups when you want to keep your own copy.
