Toka keeps language and location as separate choices, so a family can live in one country and read Toka in another's English. Both are on your profile.
Choose your language
Under Language, pick English (US) or English (UK). It saves straight away, and the page reloads in your choice.
Your language sets the wording and spelling you see, along with how dates and numbers are written. It's your own setting — a co-parent can choose differently.
Set your family's location
Click the pencil beside your name — Edit profile.
Under Location, choose your Country first.
Choose or type your Region, then type your City.
Click Save.
Location belongs to the family, so a co-parent sees the same place. It can appear on your public profile only if you allow it; see control what others see.
