LinkUzz app for iPhone and iPad

LinkUzz…
• Hugely supports you in keeping your iOS address book up-to-date.
• Instead of maintaining the data of all your contacts, you create an address book entry for yourself and just keep that one up-to-date. Once being linked with other users, you can share arbitrary parts of your contact information with them, and vice versa. The exchange of the shared data happens automatically.
• Thanks to the utilization of modern end-to-end cryptography, this synchronization takes place in such a way, that neither Privazzy – as the operator of LinkUzz – nor any third party has access to your unencrypted contact information.
• Where possible, your account is automatically connected with other LinkUzz users in your address book. By using one-way hash functions (basically a cryptographic fingerprint), this is possible without transferring any unencrypted data. Such a link will only be established, if two users already know each other (i.e. both already have an email address or telephone number of each other in their respective address books). Alternatively, you may also manually invite your family, friends and colleagues via email or messenger.
