Software licence summary

This page summarises how we intend to license FlowtheraSI software. The full end-user licence agreement will be published before the first public release, and that agreement will govern.

Free tier

Each product has a free Community tier that you may use at no cost, for personal or commercial purposes, without an account.

Paid licences

• Subscriptions (monthly or yearly) unlock paid features for as long as the subscription is active, plus a short grace period.
• One-time licences unlock paid features permanently for the version you buy, and include updates for 12 months. After that, the version you have keeps working with its paid features; newer versions run as the free tier unless you renew updates.
• Offline use. Licences are signed files checked on your own machine. They work without an internet connection.
• No hidden switch. We will not remotely disable software you have paid for. If a subscription ends, the software returns to the free tier; your data stays where it is.

Devices

A personal licence will cover a small number of your own devices. Team and server licences are counted per seat or per machine.

Open-source components

Our software includes open-source components under their own licences. See open-source notices.
