It seems that this field that we have available for a long time in the information of our contacts will be modified or rather restricted in the next version of iOS. Apple ends the possibility that users have privacy issues in this section for recording important information that third-party applications may obtain without us noticing.
Really and personally speaking I do not have any contact in my agenda in which I have added a comment in Notes, so I suppose I will not be the only one. Obviously other users will use this option to add additional data to the contact and this data can be seen by any application installed on our iPhone or device that asks permission to access the contacts, so Apple took care of remove access to "Notes" in the next version of iOS.
Many applications ask permission to access our contacts
From WhatsApp to Skype through Telegram, Uber, Facebook, among many other applications. All of them ask us for permission to access our contacts and once accepted all of them can see the complete information that we have in the contact, from the email to the "Notes" that we have listed in this section. That is why Apple limits access to the field to avoid possible problems with the privacy of our contacts.
If you want to save important data of your contacts, the best thing you can do is create the iCloud keychain directly, an app like 1Password or even the application itself Apple notes with access password to save sensitive data. In this way, you will avoid unexpected problems and prevent other users from being affected when a third-party app asks you for access to your contact list. While iOS 13 does not arrive, the best thing you can do if you have sensitive data in this section is to move it to a more secure site.
