How would you save the "reject all" selection without using a cookie for that user's session?

[starbugs]

The cookie for saving the preference is technically required. Hence, it doesn't need consent.

It's not PII so you can just use a cookie.

I think you don't need a cookie for that. You can use localStorage which is local to the user's device.

[starbugs]

It doesn't matter what method you use. Saving the information on the user's device and making them potentially identifiable is what counts.
