Win/Apple subscription

I already have a paid Lumabooth subscription.

I use Lumabooth on a Windows PC for my photo booth. I would like to know if the same subscription can also be used on a Mac or iPad when the Windows PC is not being used at the same time.

I do not need simultaneous use on multiple devices. I only want to use one subscription across different platforms for a single user.

Please clarify whether this is supported.
