Create an account before Polar
A DiskPast account keeps your license key where you can find it later. Use the same email you will enter on Polar. Paying still happens on Polar; this step does not charge you.
Polar’s tax receipt does not include the DP- key. An account is the reliable way to recover it.
You can skip, but you will need the key from the success page (or Polar checkout email for support). Account recovery is easier. Continue without an account
