Posedge Daily is a product of Thinkerfly Labs LLC, 5441 S Macadam Ave, Suite 6863, Portland, OR 97239. We store the email or provider identity you sign in with, your scores and pass-or-fail results, and your discussion posts. Code runs in a throwaway sandbox with no network access and is deleted after each run; we keep the result, not the code. We use Google Analytics for aggregate usage, which never receives your code or email. Contact [email protected].
