  "abstract": "Recent searches for $C\\!P$ violation in charm-hadron decays at Belle and Belle II are presented. The measurements cover $D^+_{(s)}\\toηh^+$, $D\\toππ$, $D^0\\to K_S^0K_S^0$, and $D^0\\toπ^+π^-π^0$, together with the singly Cabibbo-suppressed baryon decays $Ξ_c^+\\toΣ^+h^+h^-$ and $Λ_c^+\\to ph^+h^-$, where $h=π,K$. The Belle II analyses use the Run~1 data sample of $428\\,\\mathrm{fb}^{-1}$, supplemented by $980\\,\\mathrm{fb}^{-1}$ of Belle data for the $K_S^0K_S^0$ measurements. We report preliminary results for the $ηh^+$ modes, complementary tests of the isospin structure of $D\\toππ$, and an application of inclusive charm-flavor tagging. The first individual decay-rate asymmetries in these three-body charmed-baryon modes also provide tests of $U$-spin symmetry. All reported asymmetries are consistent with $C\\!P$ symmetry within the present precision.",
