When modeling dark matter in particle physics it is generally assumed that its decay into SM particles is protected by (ad hoc) stabilizing symmetries. The impact of gravity is however neglected. In this talk I will explore a scenario in which dark matter is allowed to decay into the SM through (non-minimal) interactions to gravity. I will show that this gravitational portal turns out to be very predictive and, based on current observations, also rather constrained.
