I need a user diagram of the following app specification.

First, the parent will have to register in the app by filling in a form with the necessary information, and they will also have to create a profile for each of their children.

Once the profiles are created, the parents will have to add the device that the child usually uses, the app will ask for the type of device, the brand and the model of the device and once this is done, the parents can start setting the time limits for the use of the devices for each of their children.

The app will also allow the parents to block certain websites, applications and even specific devices, this will ensure that their children are not accessing pages and applications that are not suitable for them.

The app also has a section for tasks, in this section parents can create tasks for their children to do, such as doing the homework, helping at home, reading, etc., and assign a number of points for each task. The children can accumulate these points and exchange them for rewards that the parents decide.

Finally, the parents will have access to the information of the use of the devices of their children, they can see the time of use, the pages visited, the applications used and the tasks carried out. This will allow them to monitor the activities that their children are carrying out with the devices and ensure that they are using them responsibly.
