If you are going to be collecting a lot of data with this plugin you may want to save your data to your server after each trial and not wait until the end of the experiment to perform a single bulk upload. You can reduce the amount of data generated by turning off storage of the individual stroke data ( save_strokes: false) or storage of the final image ( save_final_image: false) if your use case doesn't require that information. Each trial can easily add 500kb+ of data to a final JSON output.
