About Rebranding Again

Good afternoon. My question is:

Is there any way to hide alerts, marketing messages , invitations to seminars etc. on applications made with ZOHO creator . I am a freelance programmer I'm starting to work with ZOHO seriously , I upgraded my account to enterprise , and I would like to offer my work without customers know what my methodology and what my economic gains , since it could easily deduce at your price list. Is there an alternative to further consider ZOHO creator as my work tool ?
I have seen that within the known issues , is the impossibility of rebranding in mobile applications , something very important to get to like my clients . I look forward to your quick response .

thanks in advance.
