[Koha] definition of "default" patron privacy

[Steve Campbell]

Folks,

In Koha 3.8 a patron has a "my privacy" tab. On that page the patron can set their reading list privacy policy to one of three values. One possible value is "Default." The explanation says "the library will keep your reading history for the duration permitted by local laws."

Where is this value defined? I cannot find any system preference where "local laws" are defined.
