Your logo shows up at the top of your booking page. The favicon is the tiny version that shows in browser tabs. You can upload both from one screen.
Upload your logo
Sidebar → Branding. Drag a file into the Logo box, or click and pick one. PNG, JPG, SVG, or WebP all work. Files up to 5 MB.
Don't have a logo?
Skip the logo. Callisto falls back to a clean text version of your business name in your brand color, which looks polished enough for v1.
Favicon
The favicon should be square. If you upload one that isn't, we'll crop it from the center. PNG or SVG, ideally 256×256 or bigger.
