FAQ

Common questions

Does it really work without the internet?
Yes. GanttOWN is a native desktop app. Once installed it works completely offline. Your project files are saved locally — no cloud sync, no account required after activation.
What does "one-time purchase" mean exactly?
You pay once and own the software. There are no monthly fees, no renewal charges, and no feature lockouts. Your purchase includes free updates for 12 months.
Can my team collaborate on the same file?
Yes. Save your .gantt file to a shared network drive, SharePoint, or OneDrive. Team members open it directly — no server setup required. File locking prevents simultaneous edits.
What's the difference between the tiers?
The tiers differ in both team size and collaboration features. Solo supports up to 5 members and is ideal for individual PMs managing their own projects. Team (up to 20 members) and Business (up to 150 members) unlock the full collaboration suite — PM and member roles with separate passwords, member inboxes, date change request and approval workflows, PM-to-member messaging, project log, and a full audit trail.
Mac or Windows?
Both. Your license key works on either platform. Download the installer for your OS after purchase.
