Hi there! We are really glad you like and are using the My Cycles app! Is it in your cloud? When you download it off of your cloud, you have the option to 'get started' (create a new account) OR it says "have an account?". When you click on "have an account", a log in will appear. You will need your user name or email and then your password. If you've forgotten your password, you can click on that and you will receive an email at the account associated with the app (the one you signed up with). Your information should be retained. It walks you through the different steps of setting up a profile that you already completed on your tablet and you'll just be verifying the info. Hope this helps, let us know if you have any further questions!
