Private Diary

Your diary should be yours. Not a company's, not a cloud's, not anyone's. Private Diary keeps every entry on your phone, encrypted, behind a PIN. No account. No sign-up. No ads. Nothing to sync because there's nothing to leak — we couldn't read your diary if we wanted to.

Features

• PIN lock — it re-locks the moment you leave the app
• Every entry encrypted on the device (AES-256)
• Unlimited entries in your first notebook
• Calendar view, full-text search, tags and mood markers
• Seven themes, including the Oakencode navy & gold
• Backup export and import — free, always. Your backup is free. Your words are yours.

Pricing

Free for one notebook — unlimited entries, calendar, search, tags, moods, and backup export included; the lock and the encryption are never paywalled. One-time $4.99 Pro unlock in the Play version: multiple notebooks, photo attachments in entries, sealed time-capsule entries that won't open until a date you choose, a print-ready PDF journal book, and a decoy notebook with its own duress PIN.
