- [Refunding Beams](https://guide.ci.me/en/viewer-guide/donation-guide/refunding-beams.md): CI.ME Beams can be refunded from My Page only within 7 days of purchase, if none from that purchase have been spent, and if it was not an in-app payment.
- [Chat Donations](https://guide.ci.me/en/viewer-guide/donation-guide/chat-donations.md): Send CI.ME Beams with a message TTS can read aloud or keep anonymous. Donations of 100,000 Beams or more unlock special animations and border effects.
- [Video Donations](https://guide.ci.me/en/viewer-guide/donation-guide/video-donations.md): Play a YouTube video or CI.ME clip on stream with a chosen start and end point. Cost equals segment seconds times the streamer's per-second Beam rate.
- [Mission Donations](https://guide.ci.me/en/viewer-guide/donation-guide/mission-donations.md): CI.ME viewers set a challenge of up to 50 characters with a 10-second to 48-hour limit. A failed mission still pays the streamer at least 1,000 Beams.
- [Cheer Donations](https://guide.ci.me/en/viewer-guide/donation-guide/cheer-donations.md): Pick a concert or gaming cheer effect on CI.ME, which sends after about 3 seconds if unconfirmed. Up to 100 items per cheer, and anonymous sending is off.
