Personal Diary
LifestyleFeatured ReleaseA private, offline-first personal diary and journal with biometric security, rich media attachments, voice notes, and encrypted backups.
About Personal Diary
Personal Diary is a private, lightweight personal journal designed for daily reflection, thought organization, and memory preservation. Built with a strict offline-first philosophy, all notes, thoughts, and memories remain stored strictly on your local device.
With support for text formatting, voice audio recordings, and photo attachments, you can capture your daily experiences and feelings in detail. Optional biometric authentication (fingerprint or face unlock) ensures your intimate thoughts remain confidential even if someone else handles your device.
The application includes customizable daily writing reminders, calendar-based browsing, mood and tag classification, and strong cryptographic encrypted backup and restore capabilities so you retain 100% ownership and control over your personal journal archive.
Key Features
100% Offline & Local Storage
All diary entries, moods, and notes are saved directly in an on-device SQLite database. No account is required and no diary data is sent to external servers.
Biometric & PIN App Lock
Secure your journal against unauthorized physical access using device fingerprint, facial authentication, or a passcode.
Rich Media & Voice Notes
Attach photos from your camera or gallery, and record quick audio voice memos directly inside each diary entry.
Encrypted Offline Backups
Create password-encrypted backups of your journal to transfer across devices or archive securely without cloud reliance.
Daily Writing Reminders
Configure localized notification reminders to help you build a consistent and mindful journaling habit.

Frequently Asked Questions
Does Personal Diary store my journal entries on a remote server?
No. All diary entries, photos, and voice notes are stored exclusively on your local device in a private, sandboxed SQLite database.
Can Saurabh Studio recover my forgotten diary password or backup key?
No. Because Personal Diary is 100% offline and zero-knowledge, we do not have access to your device, your passcode, or your backup encryption keys.
How do I transfer my diary entries to a new device?
Use the encrypted backup export feature in the app settings to generate a protected backup file. You can then copy this file to your new device and restore it.
Does Personal Diary require an internet connection?
No. All core journaling, photo attachment, voice recording, and backup features function completely offline.
