Tips

We offer several ways to get in touch with and provide materials to our analysts. No communication platform is completely secure, but these tools can help you communicate more anonymously. We have outlined each platform below, but please be sure to review the applicable terms and instructions as well. For more general correspondence, visit our contact page.


What makes a good tip?

A good tip will have several components. Documentation or evidence is essential. Speculating or having a hunch does not rise to the level of a tip. A good tip should articulate a clear and understandable issue or problem with real-world consequences. Be specific. Finally, a tip should be newsworthy. While we agree it is sad that elephants are being poached, this is not a newsworthy tip.

Examples of good tips include:

Here is evidence of this government representative breaking the law.

Here is proof that this company is conducting itself unethically.

We review messages regularly, but cannot promise an individual response. Thank you for taking the time to reach out to us.

Email

You may send us encrypted or unencrypted emails. Pretty Good Privacy (PGP) is an encryption software that allows you to send encrypted emails and documents. Mailvelope is a browser extension for Chrome and Firefox that makes it easy to use PGP. The extension will only encrypt the contents of the email you’re sending. Mailvelope will not encrypt metadata such as sender, recipient, subject, or information about when the email was sent. This metadata will be available to your email provider.

Whatsapp

WhatsApp is a free messaging app owned by Facebook that allows full end-to-end encryption for its service. Only the sender and recipient can read messages, photos, videos, voice messages, documents and calls. Though you can limit some account information shared to Facebook, WhatsApp still keeps records of the phone numbers involved in the exchange and the users’ metadata, including timestamps on messages.

Signal

The free and open source messaging app offers end-to-end encryption to send messages, photos, video and calls. Signal retains only your phone number, when you first registered with the service, and when you were last active. No metadata surrounding communications is retained. The app also allow messages to self-destruct, removing them from the recipient’s and sender’s phones (once it’s been seen) after a set amount of time.
