WhatsApp is a free encrypted messaging app, which means only the sender and receiver can read the messages. The app allows you to send text messages, images, videos, audio and text documents. In case messages are intercepted by third parties, they cannot be read because of the encryption the app uses.

However, because some information about you as a user is stored on WhatsApp servers (phone numbers, certain types of metadata, including timestamps on messages), the app is not completely anonymous. Furthermore, WhatsApp is owned by Facebook, and certain types of data is shared with Facebook, although this does not include actual message content.

If you use WhatsApp to contact us, be aware that you also share your phone number with us.

Signal is a free messaging app similar to WhatsApp, but it stores less information about its users. Signal only registers your phone number and the last time you used the app. Other metadata like timestamps on messages are not recorded.

Signal also offers the option to send messages that self-destruct after a set time after the message is seen. You will disclose your phone number with us when you send a message.

If you choose to contact us via phone, Signal is the preferred way.


Secure Drop

SecureDrop is an encrypted submission system that is highly recommended if you value both confidentiality and anonymity and can only be access using the Tor browser.

Because it uses the Tor network, your identity, location and other information will be protected. SecureDrop allows us to communicate while keeping both parties completely anonymous from each other.

To ensure the security and anonymity of our sources, the I-Unit’s address is posted here:

To use SecureDrop, you must:

– Download and install software to access the Tor network: (if this web page is blocked in your country, you can send an email ( or a direct message on Twitter to @get_tor to get a direct download link.

– Once you load the Tor browser, copy and paste one of the addresses above  into the Tor address bar. You will then find additional instructions on how to submit files to Al Jazeera.

– A randomly generated, unique code name will be assigned to you. If Al Jazeera wishes to contact you, we will do so in your SecureDrop. These messages can only be accessed using your code name.

– Using the Tails operating system is recommended to increase security.

– More information on the Tails operating system can be found here.
