If you got Browsec Premium on iTunes, Browsec will work in Premium mode on all devices with the same Apple account.
Also, you can use Browsec Premium on all other supported devices (up to 5 in total), and a Browsec account will help you with that. You can create it here.
Open Browsec on your iOS device, tap for menu, then tap 'Sign in':
Enter your email address and tap 'Continue':
Enter the password for your Browsec account and tap 'Sign in':
You can reset your Browsec password anytime here.
Once you've signed in, Browsec Premium will get linked to your Browsec account. Sign in to use Browsec Premium with any other devices and desktop/laptop browsers:
Note: if you were signed in on any device before getting Premium or linking it to your Browsec account, please sign out and back in. Browsec does all the linking and checks for Premium on sign-in.
