Description

📖 Mumu Diary — Your Own Private Diary

A fully offline encrypted diary — no internet, no uploads, no account required. All your data stays only on your own device. Writing a diary is your quiet time with yourself; Mumu Diary offers a secure, private, and beautifully simple space to record, so every meaningful moment of every day stays safely yours.

【Why Choose Mumu Diary】
✓ Fully Offline — No internet, no account, no data uploaded anywhere
✓ Multi-Layer Encryption — Login password + fingerprint unlock + per-entry encryption (AES-256-GCM)
✓ You Own Your Data — One-tap backup to a file; just import on a new phone to migrate
✓ Rich Recording — Text, photos, voice, weather, mood, location — capture the full moment of each day

【🔐 Strong Encryption, Total Privacy】
Your diary content is protected with military-grade AES-256-GCM encryption. All data is stored only on your local device and never uploaded to any cloud server. Even if your phone is lost, no one can view your entries without your password.

【🔑 Dual Protection, Peace of Mind】
Sign in with a password and unlock quickly with your fingerprint — security and convenience together. For your most private entries, set a separate encryption password for an extra layer of protection — even when signed in, others cannot easily view them.

【📷 Rich Entries, Capture Every Moment】
More than just text: insert photos and audio files into your diary, or record audio directly. Combined with weather, mood, and location tags, every entry becomes rich with detail and feeling.

【✍️ Powerful Editor, Format with Ease】
Bold, italic, underline, font color, font sizes, and more rich text formatting. Supports first-line indent, paragraph alignment, and ordered or unordered lists — give every entry a polished look.

【🔍 Global Search, Find Anything Anytime】
Search across all your diaries by keyword, or quickly filter by date, weather, or mood. Even encrypted entries can be found by date and tag, while their content remains password-protected.

【📤 Data Backup, Worry-Free】
Export all your diaries and media to a backup file. Restore anytime you need — never lose your data when switching phones.

【🗑️ Recycle Bin, Recover Deleted Entries】
Deleted entries are kept in the Recycle Bin for 30 days. Restore them anytime within that period — never worry about accidental deletion again.

【⏱️ Auto-Lock, Protect Your Privacy】
Set an auto-lock timer for inactivity. The app returns to the login screen after the set period, preventing others from peeking when you step away.

【📅 Calendar View, At a Glance】
A month grid shows when you've written entries. Green marks regular entries, amber marks encrypted ones — see at a glance which days hold a story.

Simplified Chinese / Traditional Chinese / English
