We only use FB and Twitter for easy sign-up/sign-in. We'll be introducing posting to FB wall / tweeting workouts/achievements soon, but that will be totally optional. We'll never post to your social network accounts without your explicit permission.

Email addresses are a concern as well, of course. We won't email you unless you authorize us to do so in your account settings.

Add something like that to the signup process then. I doubt that I'm the only one that just didn't dare to hand out Twitter access to ~something unknown~. Especially with the social media abuse we've lately discussed in several posts on this board.

Something like 'We never post something without your consent but might allow you to share your achievement in the future' or a more eloquent version might have relaxed me enough to hit 'yes'..
