A: Hello FunkyPineapple,

Thank you for your email and your interest in TidyCal!

You would not be able to pay once and have multiple domain installs; instead, you will want to get an individual license for each client on their behalf! :)
All users of TidyCal are currently seeing our subtitle branding, and there is no option that will allow removal of the same.

We trust this will help, and if you have any further questions, feel free to email the support team at support@tudycal.com, and we will happily assist further!

Have a wonderful weekend and kind regards from the Team Originals!
