Why does CrookCatcher need access to my Gmail account?

Unlike other security applications, CrookCatcher does not rely on a third-party server for sending emails. Privacy is important, so CrookCatcher instead uses Google's authorization system OAuth2.0 to safely send emails directly from your device. This will not give CrookCatcher access to your email addresses or contacts. CrookCatcher will only use this permission to send security alert emails from your Gmail account to the email address defined by you from within the app. If you still feel uncomfortable with it, you can always create a new Gmail account just for CrookCatcher.

Can I get CrookCatcher for iPhone?
