Abstract
We review the Belle~II measurements related to the \textit{CP} violation which are based on Belle~II data collected between 2019-2022 and corresponding to $365\,\textrm{fb}^{-1}$.
The data were taken in the $e^+e^-$ collisions at the $\Upsilon(4S)$ resonance energy $\sqrt{s} = 10.58\,\textrm{GeV}$.
The discussed results include the time-dependent measurements of the $\sin 2\phi_1$ parameter in tree-dominated and loop-dominated $B^0$ decays, as well as measurements contributing to the global fit of $\phi_2$.
All of the presented measurements are statistically limited and are expected to improve with future data taking.
