Logo, colour, background, and how the links you send look.
The studio's logo and colour go in Settings → Branding. The colour is used on buttons and accents, both in the app and on the client pages.
There you also enter the address, phone, website and social networks, shown in the footer of the client pages.
Confirmations, reminders, deposits and invitations each have a preview card: the logo, the studio's name and a short line about what it is (for example the date and time of the appointment).
If you have set your own background, the card uses it too.
The background appears in the app, on the client pages and on the preview cards, so everything looks the same.
You choose how the photo is placed, how blurred it is and how dark, so the text stays easy to read.
