Every customer of Comb is given an Account so they may access their scans from the Comb Portal. Every Comb Account is linked to a specific iPhone device. After you login on a specific device, you can only transfer your account between devices once every 90 days.
Once you're logged in, all your scans will be uploaded to the Comb Portal. To access and download your scans, simply login to you Comb Account on any desktop.
