baban9999ytr/LifeDiary — reverse-engineered prompt

Build me a private Android diary app that feels polished and simple to use. I want it to be fully local on the device, with no cloud sync, no ads, and no tracking. It should support multiple accounts on one phone with local sign in, and every diary entry should stay private unless the user chooses to export it.

Each entry should support text, a cover photo, multiple photos or videos, voice notes, and even a little drawing canvas for freehand sketches. When someone creates an entry, it should be able to add city level location, current weather, and step count info from Google Fit. I also want hidden entries, plus the option to lock specific entries with a password.

Make the writing experience customizable with different fonts and text colors. If possible, include optional streaks and simple writing stats like longest streak, weekly word counts, and a yearly view of writing days, with those features being toggleable per user.

Please make it feel like a real everyday diary app, clean, private, and reliable. Look up current Android docs online if you need to.
