Welcome to Addessum,

We believe in privacy! Therefore we developed the worldwide, free and secured address directory, where you can find your contacts and manage them in your personalized address book; and only you decide who can see your contact details.

So, what is brilliant about this idea?

You have no more effort in keeping your complete address book up to date! All your contacts update their own details and this information is automatically updated in your address book and your can access your contact details from anywhere in the world and from all your devices!

Never lose any addresses of your family and friends again!
Never lose control of your personal data!
