After reviewing combined solutions of flavor anomalies with the singlet and triplet scalar leptoquarks S1 and S3, I will present possible connections to Kaon physics observables. By assuming a flavor structure for the leptoquark couplings dictated by a minimally broken U(2)5, we find that bound on Br(K+→π+νν) from NA62 puts already some tension in the model, while the present limits on Br(KL→μ+μ−) and μ→e conversion in nuclei can be saturated. Relaxing instead the flavor symmetry assumption we study what values for Br(K+→π+νν), as well as for Br(KL→π0νν) and Br(KL,S→μ+μ−), are viable compatibly with all other phenomenological constraints.
