How donations work

Flow version 1.x is donation-ware. Visit the donation site to contribute. Donors receive a licence file that unlocks dark mode and the iLogic Rules module.

Place the .lic file in your shared configuration folder. Every workstation is licensed automatically — no per-user activation, no internet required for daily use.

Team licensing

For teams, drop the licence file into your shared network folder alongside the configuration XML. All workstations pointing to that folder are licensed on next restart. One file. Your entire team.

Offline verification

Flow verifies licences locally — no internet connection is ever required during normal use. Only the initial download and optional donation transaction need connectivity.
