> “Disable chat logs in whatever program you’re using, Gmail or
> Skype,” says Soltani. In Gmail, that means switching chats to “off
> the record.” In Skype, it means turning off the feature that
> automatically saves your chats to anywhere you log in. (Added privacy

> sexy chat you had on your home computer.)
> If you need to keep a record of a chat, save it as a Word file on your
> own computer, and encrypt it.
> “Don’t keep emails around for years and years,” says Soltani.
> “Practice better data hygiene.”
> Soltani says journalists and sources might consider setting up temporary
> email accounts to communicate about a story, and then to delete the

> communications with someone not be compromised, it’s worth it. This
> means your emails will appear as gibberish to anyone you don’t want
