twinme private messenger

twinme is a mobile private messaging application allowing to make high definition voice and video calls and exchange content, without providing any personal information: no phone number and no access to your device address book. All end-to-end encrypted exchanges happen in peer-to-peer, with no staging servers storing data in between devices. twinme allows you to define, manage, and revoke, your contact information, which is unique to each of your contacts, not transferable, and not usable by anyone else. You define how you want to interact with each of your contacts, whether a family, a friend, a colleague, or a complete stranger met at a social event. No unsolicited calls, no harassment, no spam: “You” are in control! twinme is freely available on Apple and Android mobile devices.
