A conversation can last for as long as a translator is willing to help. We reach out to translators with an expectation of 15 minutes, but we have found translators might stay well past 60 minutes if they are truly helping someone in need. We recommend informing our volunteer translators of the estimated time they will be needed before beginning a session.
If a conversation is not ended manually, it will automatically end after 720 minutes (12 hours) of inactivity from either side. This is to open up the translator to help others.
