Dead Drop

Offers in-app purchases

DeadDrop is a non-instant messaging application focused on complete and perfect privacy. This not only involves proper end-to-end encryption, but also meta-data encryption using Private Information Retrieval.

This means it is impossible to tell who is communicating with whom, even for an attacker that has access to all internet communication or even the Dead Drop servers. Nobody, not even us, are able tell whether you are communicating at all.

All meta-data of every communication is protected not by policies, laws or log removal, but hard cryptography. The time of communication, size of messages, parties involved, even the very existence of the communication is secured.

The application builds on a zero-trust principle. Not even the DeadDrop servers are trusted.

Usage of the application is free for a month, then requires paid subscription!

Because of the computationally expensive cryptography involved, there are some usability trade-offs. Currently the application can only send and receive one message per one hour! Each message is limited to 10KB of text.
