A: Hello Larsbfk,

Thank you for your email!

To add a logo to the booking page, you may use your profile image and set the logo using that image placement feature.
If you have an idea of some other place where you would like to see your logo, such as booking header, you may add your request or idea here: https://roadmap.TidyCal.com/ideas
The more upvotes an idea gets, the better your chances are...
