Deep check messages the app isn't sure about, in Settings: When a message is rated Suspicious, send it for a Deep check automatically, hidden the same way as when you check one yourself. Uses your plan's Deep checks. Off by default.
It's off until you turn it on, and works only on a phone linked to an account whose plan includes Deep check.
What's sent is exactly what you'd see when checking a message yourself: the text with numbers, e-mail addresses, your name and link details hidden, the sender's type and country, and the app's reasons.
What it changes: like a manual Deep check, the result can only raise a message's risk and add reasons; it never moves a message to your inbox or deletes anything.
Each automatic check uses one of your plan's monthly Deep checks. The website's overview shows how many are left.
