After leaked emails dominated the 2016 presidential election, Washington is trying to find new ways to keep its messages safe.

Confide is becoming an increasingly popular communication tool among Republican operatives, according to Axios. The app, which uses an end-to-end encryption method, deletes messages from Confide's servers after they are read by the recipient. (Think: Snapchat, but just for messaging.) What differentiates the messaging app from others is that it also makes it difficult to take screenshots, since it doesn't display the entire message at once. Users must swipe their screens to read the next portion of text.

A GOP operative who spoke with Axios said that since the Democratic National Committee's email servers were hacked during the 2016 election, political operatives are on edge. "For folks that are on the inside in this city, it [Confide] provides some cover."

Confide was founded in 2014 by four tech veterans, including Howard Lerman, the current CEO of Yext, a startup that helps businesses manage local listings. He is also the chairman of Confide. So far, the startup has raised $3 million from investors, including Google Ventures.
