About Us

Who are we?

G-TAC Software was founded by Carsten Schaefer. We are a small team of software developers distributed over various countries.
We work in a loosely coupled team and try to build products that delight our customers.

What do we do?

We are developing tools for Microsoft Windows® environments and a cloud-based, cross-platform application for organizing and sharing notes, TheNoteTank.
As part of this project, we've developed a variety of tools and components, two of which are DrawerJs and ImagerJs. Because we invested a lot of time crafting those components, we decided to also sell them as separate products.


Additionally, we've developed a NTFS permissions reporter FolderSecuritysViewer to analyze Microsoft Windows® security rights on file systems. We find this tool to be incredibly helpful to analyze NTFS permissions and to generate NTFS permissions reports. We think you might like our FolderSecurityViewer, too.
