  The LHCb Collaboration has recently measured the difference of
time-integrated $CP$ asymmetry in $D^{0}\rightarrow K^{+}K^{-}$ and
$D^{0}\rightarrow \pi^{+}\pi^{-}$ decays, more precisely. The reported value is
$ \Delta A_{CP}=-0.10 \pm 0.08 (\text{stat}) \pm 0.03 (\text{syst})\% $ which
indicates no evidence for $CP$ violation. We consider the possible unparticle
physics contribution in this quantity and by using the LCHb data try to
constrain the parameter space of unparticle stuff.
