Vovsoft Desktop Diary: A Private, Password-Locked Journal That Stays on Your PC
Desktop Diary is a $19 Windows journal program from Vovsoft: a calendar on top, a formatted entry for each day below, and a password on each user account, with everything kept offline on your own computer. The $19 is a one-time lifetime license, and there's a free trial.
It's for people who want to keep a daily diary or log on the computer without handing their private thoughts to an online journaling service.

Overview
Log in to your account and you see three months of calendar across the top, with days that have entries in bold. Click a day and write in the editor below, with a toolbar for alignment, lists, bold, italic, underline, strikeout, colors, highlighting and pictures. A search box finds old entries, and Print sends an entry to the printer. The status bar shows who's logged in and the date you're writing for.
A diary entry with a heading, a picture and text on a patterned dark theme, under a three-month calendar with filled days in bold.
Features
Password-protected accounts
Desktop Diary keeps each person's diary behind their own password, so several people can share a PC without reading each other's entries. Nothing is ever sent online.
A calendar that doubles as an index
Desktop Diary's calendar shows which days have entries, lets you jump to any date, and works as a place to note appointments as well as memories.
Formatting, pictures and themes
Desktop Diary formats text like a small word processor and inserts pictures into an entry. Its many color themes and background images (JPEG, PNG, GIF or BMP) change the look, and any installed font can be used. Entries can be loaded from DOCX, RTF or TXT files.

Encrypted backups
Desktop Diary exports your diary to an encrypted backup file and imports it again, which is how you move it to a new computer or recover after a crash.
Real-World Uses
- Keeping a private daily journal that nobody else in the house can open.
- A health log for symptoms, medication and doctor visits, searchable when the doctor asks when something started.
- A work log of what you did each day, ready for a performance review.
- A gratitude or travel diary with photos pasted into each day.
Who It's For, and Who Should Skip It
It suits Windows users who want a simple, private, calendar-based diary on one computer, including people who miss old desktop journals like Parsons' Daily Journal.
Skip it if you want to write on your phone or have the diary sync between devices: it's Windows-only and offline. It also has no reminders or alarms, no time slots for appointments and no journal groups, so it's not a substitute for a calendar app.
Usage Guide
- Download and run the installer, then start Desktop Diary.
- Create a user account and set a password.
- Click a day on the calendar and write your entry. Use the toolbar for formatting and pictures.
- Pick a theme or background under Customize.
- Export an encrypted backup from the Backup menu regularly, and keep it somewhere safe.
Before you buy
The password locks the account in the program, and backups are encrypted, but users have asked for the diary's own database to be encrypted too, which it isn't yet. Keep your exported backups, since forgetting the password or losing the PC are the real risks. One license covers one person on any number of their own computers. Vovsoft's general policy is no refunds once the key is delivered, since a free trial comes first (accidental orders are generally refunded, at its discretion, and PayPro Global has the final say on its orders).
Where it falls short
- No search by date, journal groups (home, work) or spell checker. These are the most requested features.
- No reminders or alarms, and no time column for appointments.
- No portable edition, no mobile app and no sync.
- The calendar opens with the current month on the right, which some users find backwards.

Comparisons
Desktop Diary vs online journaling apps
Apps like Day One sync to your phone and add maps and weather, usually with a subscription and your entries on their servers. Desktop Diary is offline and one-time $19, but stays on one Windows PC.
Desktop Diary vs Vovsoft Tree Notes
Tree Notes organizes notes by topic in a folder tree. Desktop Diary organizes entries by date on a calendar, with password-locked accounts. Both come under Vovsoft's $99 Universal License.

Conclusion

The reason not to: no phone app, no sync and no reminders, so anyone who writes on the go needs a different app.
