It would be nice to be able to also use registration parameter tracking, also without creating a cookie / session / temp store, just using the parameters.
For example for GDPR reasons the module might be interesting without storing cookie information.
1. Add documentation what happens, if both
are left empty (add a sentence to the description like "Leave empty to disable GET parameter persistent tracking."
2. Add a none option for the storage and explain that it might be useful for tracking the registration request parameters without storing parameters persistently.
