If Speedify crashes, a report with a "stack trace" and other debugging information is sent to us via either Crashlytics or Raygun. These services help us find the source of any bugs so that we can fix them and get a new release out. This feedback loop is very important, and has helped us keep the quality of Speedify high. If you do not wish to participate in this process, you can turn Crash Reports off, and we will no longer be sent any data should Speedify crash on your system.
