Data Defender funktioniert nicht

The program allows you to create random, secure passwords that are very difficult to crack or guess due to the additional combination of upper and lower case, numbers and special characters.  Data Defender helps you securely store all your passwords and other personal information.  The only thing you need to do is remember the master password to enter the application.  The app is 100% secure as it does not have access to your recordings and uploads them to the Internet.  To unlock all features, you must purchase a premium membership.  The application has the function of blocking sites and ads in Safari.  It can be used as a parental control system or as a distraction reduction tool.  This makes your device safer for your kids and for everyday use.  Each subscription period is offered with a 3-day free trial. - Payment will be charged to iTunes Account at confirmation of purchase (after a free trial, if offered). - Subscription automatically renews unless auto-renew is turned off at least 24 hours before the end of the current period. - Account will be charged for renewal within 24 hours prior to the end of the current period and will indicate the cost of the renewal. - Subscriptions can be managed by the user and auto-renewal can be turned off by going to User Account Settings after purchase.
