Locales

The more ways you can 'slice' the audience, the more unique the fingerprints become. Locales is one way of slicing the audience in smaller pieces by checking the preferred language of the browser as well as its reported time-zone.

Obviously these are quite easy to change, and you might want to exclude them for that reason. But, if what you want is a cookieless way to calculate a fingerprint for users who aren't trying to avoid it, keeping them in are a good idea.

Example

"locales": {
    "languages": "en-GB",
    "timezone": "Europe/Helsinki"
},
