We do not log IP addresses, sites, or data that you send or receive through the Speedify service.
This allows data about what internet connections you used and what kind of performance you saw to be collected and analyzed. We use this information for performance tuning, answering questions like "Where do we need more servers?" If you do not wish to share such information, you can turn off this setting.
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.
