Hello,
If you have bought the auto-renewable subscription, you can restore it by following the steps below:
1. Go to your iPhone/iPad Settings
2. Go to App "App an iTunes Stores"
3. Login with the same Apple ID you used to buy your subscription (this is crucial to make it work)
4. Open SecureLine
5. Go to the Settings > Subscription
6. Tap "Restore Subscription" on the top and wait until your purchase is found and validated
If don't get your subscription code after that, please send the receipt of your purchase to our support. It's the email with the receipt you receive from iTunes after you buy the subscription. You should get your subscription code after that.
Regards,
Jobert
