Is LmGmail safe?

Question

Is LmGmail safe?

Accepted Answer

LmGmail is high risk. When you use Lockmagic Gmail Encryption, the extension receives a LockMagic authentication token from www.lockmagic.com/usersignin.aspx. The confirmed behavior stores that token in Gmail page localStorage, which is page storage for mail.google.com or inbox.google.com rather than extension-private storage. When you use Lockmagic Gmail Encryption in Gmail, the extension retrieves a LockMagic contact list and saves contact email data into a cookie on the Gmail page origin. That places contact-list storage in page cookies instead of extension-private storage, using the LockMagic contacts endpoint and the mylockmagiccontacts cookie described in the reviewed rows.
