Your Google account, read-only
You sign in with Google and pick the channel you stream with. Marathon-Timer only asks for read access: it never posts, never moderates, and never reads your private messages. You can revoke it at any time from your Google account or from the Connections page.
Super Chats and Super Stickers by amount
A Super Chat or a Super Sticker adds time according to its amount, with your own rate per unit of currency, exactly like a donation. A small message and a large one are not worth the same, and your rate card decides how much.
Memberships, including gifted ones
Every new member adds time. When a viewer gifts memberships, the whole batch is credited to the person who gave them, so a gift of twenty counts twenty times, and once. Milestone messages from existing members add nothing: they are not a payment.
Your live stream, found on its own
When your timer is running, Marathon-Timer finds your live stream and starts reading its chat. YouTube also notifies us when your channel goes live, so the reading starts without you pasting any link.
YouTube next to Twitch and Kick
Streaming on YouTube and Twitch at the same time? Super Chats, memberships, subs and bits all land on the same countdown, so your viewers on both platforms push the same clock.
