Documentation on how Remember Value option works in exposed filters?

Is there documentation anywhere about how the Remember checkbox works in Views exposed filter settings? (Screenshot attached.) I'm wondering if it's a cookie, or saved in the database, and if it's associated with a specific user or a session. We're hoping to be able to allow users to save their values across browsers and sessions (so if they set a filter at work and then go home and log in on a different computer, the value is still set.) Our tests thus far seem to indicate that it's either a cookie or session variable, as simply logging in to a different browser (as the same user) results in the values not being remembered, although if I close the page in the first browser and go back to it later in the same browser, the value is remembered.
