Guide: importing contacts
Conquish previews every import before saving, shows which entries will be merged with existing contacts, and never uploads your phone book anywhere else.
Open ContactsAndroid
Choose Import from phone. Supported Android browsers open your phone's own contact selector, where you pick one or many contacts. Nothing is read until you choose.
iPhone
Apple does not let a website read the iPhone address book. Instead, open Contacts on the phone, select the people you want, share them as a vCard, then choose that .vcf file in Conquish. The app walks you through it.
Computer
Export a .vcf or .csv from Outlook, Google Contacts or Apple Contacts and choose the file. Empty records are skipped and duplicates are matched on name, phone and email.
