Why can’t I log out from my account?

If you navigate to Menu ( or your avatar) > Profile and can’t find the Log out option, it means that you’re using the app anonymously without registration. To avoid losing your logged information, please log in to your existing account or register a new one: Menu ( or your avatar) > Profile (Android users only) > Continue or Sign up. 

When your Flo account is registered, the Log out button will appear in your profile.
