Terms of Service
Last updated: October 7, 2026
The service
ZeroCast is a zero-install browser screen-sharing tool: the sender shares from a browser and viewers watch via a link. Video is transported over encrypted peer-to-peer connections.
Accounts
Some features require an account. You are responsible for safeguarding your credentials; activity under your account is treated as yours. Contact us immediately if your account is compromised.
Free and paid plans
Guests receive 720p and 15 casting minutes per day; free registration unlocks 1080p HD and a total of 40 minutes per day. Both include one viewer and a watermark. Normal and invited casting count toward the screen sharer's daily allowance; watching does not. Time already used carries over after registration. Allowances reset at 00:00 Beijing time (UTC+8). Pro and Premium unlock voice talk; Premium unlocks camera video calls. The room creator's plan (the inviter for invited sharing) unlocks calls for both participants. Other paid benefits include multiple viewers, no watermark, unlimited duration, room passwords and recording. Cancel anytime; benefits last until the end of the current billing period.
Acceptable use
You agree not to use the service to distribute unlawful, infringing, pornographic or violent content, or to violate others' privacy or intellectual property. We may suspend or terminate service for violations and cooperate with authorities as required by law.
Disclaimer
The service is provided “as is”. Given the variability of networks we cannot guarantee connection success or quality in every environment. To the maximum extent permitted by law, we are not liable for indirect losses arising from use or inability to use the service.
Changes to these terms
We may revise these terms from time to time; material changes will be announced prominently on the site. Continued use means acceptance of the revised terms.
