I know cookies are not in accordance with total privacy,
but Proton itself offers to store ones login credentials
(in my case on my very own laptop).

Unfortunately a login, regardless whether made form mail or the calendar, is never stored, requiring one to login again anew next time.

If proton does not like to store cookies it makes sense for me not to do so, but to offer to remember logins in the tickbox below -and then not following up with it, seems frustrating.

So either make those cookies work, or delete the option for it, please.
