Data Management and Security

Even in corporate environments with strict cloud policies, Ploto can be deployed without complex security assessments.

🔒

Local-First Architecture

All data is saved in a local file (.ploto) on your PC. It never transmits schedule data or task descriptions to external servers, making it ideal for closed intranets and confidential projects.

🏪

Microsoft Store Secure Distribution

The app is signed and distributed via Microsoft Store after rigorous security scans. Unlike unofficial installers, it simplifies procurement approval from internal IT departments.

👤

No Account Creation or Sign-in

No email registration, logins, or corporate domain details are needed. Just install and run immediately in an isolated offline environment.

Solve Your Excel Frustrations with Simple Features

Ploto is designed to eliminate the tedious repetitive tasks commonly found in spreadsheet-based management.

3-Color Health Status Alert

Automatically highlights tasks as red (overdue), yellow (delayed), or green (on track). Quickly spot bottlenecks without manual checks.

Holidays & Company Calendars

Configure custom holidays and work schedules. Weekend dimming and holiday highlighting ensure accurate capacity planning matching your real schedule.

Recover from Mistakes with Ctrl+Z

Just like Excel, you can undo (`Ctrl+Z`) or redo (`Ctrl+Y`) operations like drag-and-drops, creations, or deletions. No fear of misclicks.

Offline Storage for Strict Data Protection

All data is stored directly on your PC as standard files (.ploto). Because no cloud connections are established, confidential project data never leaves your environment.

See It In Action
