How to get Siri to not call you by name
It's easy to make Siri forget your name by creating a sacrificial contact:


Open Contacts and tap the plus sign to create a new entry. Enter any text you like for the name. Tap 'Done'.
Open the Settings app and go to Siri's options under the 'General' tab. Tap on "My Info" and change the contact from you to the one you just created.
Go back to the Contacts app. Select the new contact, tap on 'Edit', scroll down until you see 'Delete Contact', and tap on it.


That's it—you're done. Siri's settings will now show "None" next to "My Info".
