Flares are unmistakeable signs of stellar magnetic activity, and a key to our understanding of stellar properties and evolution. They are violent explosions that penetrate all layers of a star's atmosphere, and enhance its overall brightness by up to orders of magnitude within minutes. We observe flares as distinct signatures in time series of stellar photometric observations that we call light curves. Flaring rates and energies provide unique insights into the nature of the stars that produce

Space missions like Kepler (Koch et al., 2010), K2 (Howell et al., 2014), and TESS (Ricker et al., 2014) have collected light curves of tens of thousands of flaring stars, for timespans ranging from several weeks to multiple years. As TESS continues to gather high-cadence data, we developed AltaiPony to aid astronomers who require accurately characterized flare samples for their research. AltaiPony is a toolbox for statistical flares studies on photometric time series from these missions, including flare search and characterization, a framework to determine the algorithm's efficiency, and statistical analysis of flaring rates along with extensive documentation and Jupyter-based tutorials.
