Switch Accounts: Clicking this option will log you out of Speedify, so that you can switch accounts.
Manage Subscription: By clicking this option you are taken to a page on the store where you can choose to edit your subscription or cancel your subscription. Depending on whether you purchased from the Speedify site, the App Store or the Play Store, you will be sent to the appropriate location.
Change Password: You can change your Speedify password here.
Share: Opens your web browser and gives you the option to share Speedify on select social media sites.
