FAQ

Your work is already saved. Every change is continuously saved to your device as you work. After restart, just reopen MasterGantt — your project reloads exactly where you left off.

MasterGantt also guards against accidental closure: a warning appears if you try to close the app with changes not yet exported to a file.

Your data is saved in the app's private storage area on your own device. It is never sent to a server, never transmitted to Cloudflare, Google, Microsoft or Anthropic, never indexed by a search engine.

This area is persistent: it is preserved across sessions, restarts and updates. It is only removed if you explicitly choose to clear the application data from settings.

Real-time collaboration (optional, end-to-end encrypted) is the only case where data transits through a relay — and even then: the relay only sees AES-256 blobs that are unreadable without your password.

MasterGantt combines 4 complementary protection layers:

A restore point (snapshot) is a complete photo of your data at a given moment, kept securely on your device. You can create them manually, and MasterGantt creates them automatically before every import, export or major deletion.

Up to 10 restore points are kept (oldest are replaced automatically). Each point shows the date, task/resource/project counts and the creation reason.

You can restore or download any restore point from Settings > Data > History.

Auto-save automatically downloads a copy of your data to your Downloads folder at regular intervals.

Configurable interval: 5, 10, 15, 20 or 30 minutes (default: 10 min).

File format:

Filename is automatically timestamped: mastergantt-2026-04-10-14h35.json

In Free edition, exports are unencrypted:

• JSON — full export, no password
• CSV — by category (tasks, resources, projects), no password

In Pro edition, all exported data is encrypted:

• .mgp — AES-256-GCM encrypted file, password required (4 char. min.)
• License binding — option to tie the file to your license. The file can then only be decrypted by that license holder.
• CSV — also available (tasks, resources, projects)

Import is available in both editions (Free and Pro) and supports all formats:

• .json — direct import (drag & drop or file picker)
• .mgp — password is requested for decryption
• Pasted JSON — paste JSON directly into the text area

Two import modes:

The Reports tab groups all indicators into 5 collapsible sections:

The health score (0 to 100) aggregates 4 dimensions: Planning, Budget, Resources, Quality. Color-coded: 🟢 ≥80, 🟡 60-80, 🟠 40-60, 🔴 <40.

The Gantt displays up to 6 element types, each with a distinct visual rendering:

Visibility toggles in the Gantt toolbar:

• Tasks — active by default
• Purchases — show purchases under each project PRO
• Absences — show resource leave periods PRO
• Workload — bottom section with per-resource workload bars (overload alert ⚡)

Dragging a task to the "Done" column in Kanban triggers an automatic cascade:

• Status → moves to s5 (Done), actual end date recorded
• Dependencies → dependent tasks (FS) are unlocked and move to "To Do"
• Project dates → automatically recalculated (ahead or delayed)
• Program dates → recalculated if the project belongs to a program
• Critical path → alert if the completed task impacts the critical path

A summary toast appears as a single notification:

In the navigation bar, 3 view modes let you filter the entire application by role:

Once activated, a name-based filter bar appears. Click names to refine. The filter applies across all views:

• Gantt — only tasks/absences for selected people
• Kanban — cards filtered by resource
• Task list — filtered table
• Reports — KPIs recalculated on the filtered scope
• Dashboard — weekly todo only for selected people

The Dashboard tab provides a complete weekly overview in 3 columns:

The Hero section at the top shows gamification: tasks completed this week vs last week, with a progress bar and motivational message.

Alerts are automatic: overdue tasks, overloaded resources, leave conflicts, budget overruns, late deliveries.

Click on a resource in the Workload section at the bottom of the Gantt. The planning instantly filters to show only:

• Tasks assigned to that resource
• Leave periods for that resource
• Only items in conflict (overload or leave overlap)

A filter badge 🔍 appears at the top of the Gantt with the resource name and an × button to clear the filter.

Once a conflict is identified (via the resource filter), you have 3 direct actions in the Gantt:

The complete resolution workflow:

The Resources tab PRO provides a complementary view with 3 sub-tabs:
