Is there a way to hide Plan Details if installing Squirrly on a client’s site?

Yes, you can remove the user information and the plan details by using the Web Dev Kit from Squirrly.

Our Web Dev Kit is created for Developers and Agencies. It comes with plugin customizations and the option to restrict the users from seeing the Cloud information.

Please take a look at this page, in the section where we compare the Web Dev Kit to the classic Agency plan we sell for more details.
