If you need to change your phone use the export and import options in csv format that will allow you to keep the information.
If you need to share information to your doctor then please use the export option in pdf format that allows you to generate a pdf with the details and print it out.
The app as it shows publicity uses a publicity id but no data related to you is being stored from my side.
In case you have any recommendation on improving the application please send an E-mail to m821926@gmail.com so we can take this into account.
