DearDiary is a mindful, AI-assisted journaling app built with Expo and React Native. It helps people capture their thoughts, track emotional patterns, and build a consistent reflection practice in a calm, private space.
DearDiary is under active development and is being prepared for an Android release.

Journal content is sensitive by nature. The project keeps privileged credentials out of the mobile client, provides local privacy controls, and routes protected operations through server-side services. Public environment variables must never contain private or administrative credentials.
DearDiary is not yet a finished public release. Features, screenshots, and behavior may change as development continues.
