Yes, it will wipe all you current progress on your device. The developers FM, have been working on this recently, the cloud save now shows the best progress, so a reset local profile shouldn't overwrite a cloud save with more progress. I would advise you save your progress, while logged into your social profile, then sign out before you clear your data, when your ready to do a restore sign back in, be careful with automatic saves every day (possibly twice per day now). I've also read posts they racers have several different profiles under different social accounts.
