We only use first names and last initials along with cities for social proof to show that people are winning.
We do allow you to be completely anonymous from the privacy settings within the app. If you don't want your first name, last initial, and city shown anywhere, you can toggle it off.
We find most people aren't sensitive about the first name last initial thing, and it helps us in terms of social proof. If we get complaints, we could swap to opt-in vs. opt-out.
