Your mobile smart device address book data will always remain private to you.

However, Kyrylity users will have access to your Kyrylity Business and Kyrylity Social address books if you both of you are on Kyrylity and both of you have saved each other’s mobile phone number to your respective mobile smart device address books.

No one using Kyrylity will have access to your mobile smart device address book data, only your Kyrylity address book data.
