Your colours, shapes and logo, made in your browser.
A photograph has light and dark patches, and a dark module sitting on a dark patch is invisible to a scanner. The picture is washed toward your background colour to flatten that — the badge above is the real contrast measured off the finished code, not a guess. Keep it at 3.0:1 or better.

Noted — you will hear from us once, when it is live.
The code is drawn in your browser. Your logo and any picture you add stay on your device: they are never uploaded.
A plain code carries your address or text inside the pattern itself. It needs nothing from us to work, so it keeps working for as long as the address does, and it is free.
A re-pointable code (Pulse) holds a short cashcallin.net link instead. You can aim it somewhere else after it is printed, and see how many times it was scanned. We count the scans and keep nothing about the person who scanned.
Not if there is enough error correction. A QR code repeats its data, so part of it can be covered and still read. Level L can lose about 7% of the code, M about 15%, Q about 25% and H about 30%. Leave it on Auto, or pick H for a large logo, and keep the clear space around the logo on.
Scanners look for dark modules on a light background. Strong contrast matters more than colour. If you put a photo behind the code, the studio washes it toward your background colour and measures the real contrast of the finished code: keep that at 3.0:1 or better.
PNG at 512, 1024 or 2048 pixels suits screens and most print. SVG (Pulse) is a vector, so one file prints sharp on a business card or a two-metre banner.
