How to communicate securely with Quartz


We love hearing from readers. You can always reach us at hi@qz.com, but sometimes more secure forms of communication are necessary — for instance, if you’re trying to send us a sensitive news tip. This page describes some methods we suggest in those cases.

Send a letter

A simple way to reach us is through regular, old-fashioned mail. US postal mail without a return address is one of the most secure ways to communicate, since a warrant is required for someone other than the intended recipient to open it. Be sure to mail your package or letter from an unfamiliar sidewalk box instead of going to a post office.

Our mailing address is:

Quartz
News Department
675 Avenue of the Americas, 4th Floor
New York, New York 10011

Send an encrypted email

Many of our reporters accept emails using Pretty Good Privacy (PGP) encryption. While all emails leave traces identifying who sent the message and to whom it was sent, PGP is a good way to prevent others from seeing the main contents of your communications. You can find PGP keys for our reporters by clicking on their bylines.

Use our SecureDrop site

We use a system called SecureDrop that allows anyone to anonymously share information and files with us. SecureDrop both encrypts all of the material sent to us, so other people can’t see what you’re sending, and obscures information about how the material reached our servers, so nobody (including us) can know who sent it.

To use SecureDrop, you’ll need to download software called Tor. But it's fairly easy to use.

For maximum security, you should not visit our SecureDrop site from your home or work, because anyone monitoring the internet connections there will know someone has used the site. You also shouldn't contact us via email or social media, all of which could leave records of your connection to us.

Terms

The Quartz SecureDrop server is designed to provide our sources with greater anonymity and security than with conventional e-mail.

When you visit or use our server at 4v6p5ajkvs54hxow.onion following the instructions provided above, we will not record your IP address or information about your browser, computer or operating system, nor will we embed third-party content or deliver persistent cookies to your browser.

Our SecureDrop servers are under our physical control in a physically and logically segregated area within the Quartz offices.

SecureDrop is designed to be accessed only through a "hidden service" on the Tor system, which is set up to conceal both your online and physical location from us and to offer encryption for your communications with us. This provides a higher level of security and anonymity in your communication with us than does standard e-mail or similar methods.

Though it is our intention to keep you and your information safe, SecureDrop does not provide perfect security — nor does any technology. Among other risks, if someone else gets hold of your computer, any activities, including communications through SecureDrop, could be compromised as well. SecureDrop is regularly audited by independent security experts, but like all software, it could have security bugs that hackers may learn to exploit.

Quartz does not make any warranties or representations as to SecureDrop. Use of the system is on an "as-is" basis. You use the service at your own risk.
