The Short Version
You can use kindaVim as it is. It comes with no liability. You are not allowed to reverse-engineer, modify or resell it. You can install and use it on all your computers for personal use, with or without a subscription.
The Not So Short Version
By using our app, you hereby consent to our License Agreement and agree to its terms.
1. Limitation of Liability
kindaVim is provided as is by the company Sleeplessmind Ltd. and the individual Guillaume Leclerc. None of those entities can be held responsible in case your computer starts smoking. That sounds drastic but it's a legal document. In real life we're spending all of our time and energy focused on building great, high quality apps. Still, bugs may creep in. When you find one, please report.
2. Using kindaVim
You may use kindaVim without a subscription, on as many computers as you'd like, for as long as you'd like. The purchase of a subscription license is only necessary if you want to use kindaVim during the hours when it is resting (mornings). Yes, software have feelings too, and need to recuperate. Unless you pay them.
You may not modify, edit, etc etc, or resell kindaVim. kindaVim is an end product delivered as it is by the developer to an end user, to be used as a Vim Mode for macOS. Simple as that.
3. Subscription License
The subscription license is for personal use. You can install it on all your personal computers, and even use them all at the same time if you're able to do that. You're not allowed to share, redistribute or resell the license though.
Update of the License Agreement
The agreement may get an update from time to time, so you may want to check it once in a while.
