My Diary - Journal with Lock

My Diary is a free, private diary app with lock to record your daily diary, secret thoughts, moods, and memories. It's a diary app with photos and doodles that supports tags, moods, stickers, and fonts — making your personal diary journal, diary book, and daily journaling more organized, vivid, and secure. Unlike other diary apps, My Diary works 100% offline — no account, no internet, no cloud required, so your private journal never leaves your phone.
Why keep a diary?
A diary is a good place to vent your emotions when you feel no one is listening. Keeping a journal helps you relive your memories — reading old entries lets you see how far you've come. Regular diary writing helps you express yourself, understand your moods, and reduce anxiety. Start small: a few sentences a day is enough. In a year, you'll love reading it back.
