Share your address book or Gmail/iCloud contacts list to find contacts on Wire more easily. When you share your contacts, Wire converts phone numbers and email into fully anonymized versions. These values are kept separate and cannot be associated with each other. Wire does not collect the names in your address book, and does not collect other information, such as notes, birthdays, etc.
On mobile, only the address book or 'Contacts' on your device are shared with Wire.
On Wire for Web, you can choose to share your Gmail or iCloud contacts list.
