  We use high accuracy photometric data obtained with the Kepler satellite to
monitor the activity modulations of the Kepler-210 planet host star over a time
span of more than four years. Following the phenomenology of the star's light
curve in combination with a five spot model, we identify six different
so-called spot seasons. A characteristic, which is common in the majority of
the seasons, is the persistent appearance of spots in a specific range of
longitudes on the stellar surface. The most prominent period of the observed
activity modulations is different for each season and appears to evolve
following a specific pattern, resembling the changes in the sunspot periods
during the solar magnetic cycle. Under the hypothesis that the star exhibits
solar-like differential rotation, we suggest differential rotation values of
Kepler-210 that are similar to or smaller than that of the Sun. Finally, we
estimate spot life times between 60 days and 90 days, taking into consideration
the evolution of the total covered stellar surface computed from our model.
