When you sign up to Habyts you automatically receive a free trial for 14 days. At the end of your 14 days you'll be given the option to sign up or cancel your subscription.
We hope that you'll stay with us! If you decide not to continue, all previous Habyts controls will cease to work and your apps will be available. You don’t need to uninstall the Habyts apps on your kids’ devices (though of course you can do so if you want).
