Short, because there isn't much to say.

When someone scans a code

We record the time, the device type, the referrer if there is one, which rule was active, and the country and city when those are known. The IP address is used to work out the country and is then discarded. It isn't stored, and there's no column to store it in.

The redirect is temporary by design, so we never tell a browser or a network to remember a destination.

When you have an account

We keep your email address, a hashed password, the codes and rules you create, and a record of the devices you're signed in on so you can sign them out. Deleting your account archives your codes first, so anything already printed shows a retired message rather than an error, and then removes you.

There's no analytics script on the app. This marketing site has none either.
