We consider a secluded dark sector exclusively interacting with leptons via either a (leptophilic) scalar or vector mediator. These interactions will therefore influence leptonic decays and deform the energy spectra. We first study the Michel decay of muons, $\\mu^+\\rightarrow e^+\\nu_e \\bar{\\nu}_\\mu$, which allow us to constrain the parameter space reasonably well. Secondly, the rare $\\pi^\\pm$, $K^\\pm$, $D^\\pm$ and $D_s^\\pm$ decays to $e\\nu$ will be considered.
