Educate me why activity tracker is used in clans?

[LEVIATHAN GRANDZILLA]

Hello all, I want to understand:

1) Why activity tracker exists?

2) how it's actually used?

3) why is there reset option for activity tracker? —I guess it applies for fame received data too?
also I never ever pressed reset button neither was in ally before so I wanna know why.

(Genuinely)

Thanks for reading!

É um sistema do jogo. É meio óbvio.
