Might I suggest an update to the website to make it abundantly clear which features are 'free for personal use' vs. those which must be 'purchased for personal use'.
This page might be a good spot to make the paid vs. free feature set clear (perhaps by adding an "*" to each of the features that require a purchased license:

BTW, the noun 'home' isn't really appropriate. I should be able to use my BRU Personal or BRU Personal+ product anywhere, as long as the objects I'm working with when using BRU are personal. I could be on a plane, a ship, at the Starbucks, even the pub. Home isn't really an applicable noun.
Thanks for reading. Cheers!
