AB  - Recent searches for C P violation in charm-hadron decays at Belle and Belle II are presented. The measurements cover D^+_(s)→ηh^+, D→ππ, D^0→ K_S^0K_S^0, and D^0→π^+π^-π^0, together with the singly Cabibbo-suppressed baryon decays Ξ_c^+→Σ^+h^+h^- and Λ_c^+→ ph^+h^-, where h=π,K. The Belle II analyses use the Run~1 data sample of 428 fb^−1, supplemented by 980 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→ππ, 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.
