Charm physics probes flavour mixing among up-type quarks and thus has a unique role in flavour physics. But decay amplitudes of charmed hadrons are difficult to predict from first principles. Especially the theory predictions for CP asymmetries vary by orders of magnitude and give no clue of the expected size of the yet unmeasured CP violation in D decays. I present an analysis of D-meson decays into two pseudoscalar mesons, which exploits the approximate SU(3) flavour symmetry, and show how the Standard Model can be tested through correlations of CP asymmetries, which can be predicted in a better way than the individual CP asymmetries.
