Acceptable Use Policy / 可接受使用政策
Effective 2026-09-14. Applies to the official CoStage channels: the CE distribution, subscriptions, source delivery and any official hosted service.
生效日期 2026-09-14。适用于 CoStage 官方渠道：CE 发行版、订阅服务、源码交付与官方托管服务（如有）。
Our standing commitment / 官方立场
CoStage will never ship synthetic voice, face or avatar features — no face swap, no voice cloning, no digital avatars, no real-time identity substitution. AI is limited to assistive teaching: captions, live translation, transcription, class notes, accessibility. We also do not provide anything that removes synthetic-content labels, watermarks or provenance markers.
CoStage 官方产品不提供、也不会添加任何「合成真人声音 / 面容 / 形象」的功能—— 不做换脸、不做换声、不做数字人、不做实时形象替换。AI 仅限辅助教学用途：字幕、实时翻译、语音转写、课堂纪要、无障碍。 我们也不提供"去除合成内容标识、绕过水印或溯源"一类能力。
1 · Prohibited uses / 禁止用途
- Impersonation — pretending to be another person or organisation (family, manager, support staff, teacher, institution, financial advisor).
冒充他人或组织——亲友、领导、客服、教师、机构、投资顾问等。 - Synthetic voice/face — face swap, voice conversion or cloning, digital-human anchors, real-time identity substitution, or integrating CoStage with such tooling.
合成或替换真人声音/面容/形象，或为此类行为提供集成。 - Fraud — telecom/online scams, fake investments, task scams, romance scams, phishing.
电信网络诈骗、虚假投资、刷单、杀猪盘、钓鱼。 - Non-consensual recording or distribution of anyone's likeness or voice; privacy or personality-right violations.
未经同意录制传播他人肖像声音；侵犯隐私与人格权。 - Harm to minors, or falsely claiming teaching credentials or institutional affiliation.
面向未成年人的有害内容；虚构教学资质或冒充机构招生。 - Evading law or platform rules — mass harassment, spam, automated abuse, circumventing identity verification or moderation.
规避法律与平台规则的技术滥用。 - Misusing the CoStage name or logo to imply official origin or endorsement.
冒用名称/标识暗示官方来源。
2 · Relationship to the MIT licence / 与 MIT 许可的关系
The source is MIT-licensed and the licence itself places no restriction on use — that openness is deliberate. This policy is a service- and contract-level commitment: it binds parties who subscribe or use official channels, and does not change the rights anyone already obtained under MIT. Enforcement is service-level: revoking subscription access, stopping updates and support, terminating the relationship. We will not — and cannot — recall code copies already delivered under MIT.
源码采用 MIT 许可，许可本身不限制用途——这种开放是有意选择。 本政策是服务层/合同层约定：约束订阅者与官方渠道使用者，不改变任何人依 MIT 已获得的代码权利。 处置在服务层进行：撤销订阅访问、停止更新与支持、终止服务关系。我们不会也无法收回依 MIT 已交付的代码副本。
3 · Reporting abuse / 举报
Report to abuse@costage.dev with links, timestamps and evidence (screenshots or recordings). We acknowledge within ~5 business days (best effort). If confirmed we revoke the offending subscriber's access, stop updates and support, file takedown requests against brand impersonation, and publish clarifications when warranted. If a scam is in progress, please report to your local police or the hosting platform first — we cannot replace law enforcement, but we cooperate with the records we hold.
举报请发 abuse@costage.dev，附链接、时间与证据（截图/录屏）。 我们 best-effort 在约 5 个工作日内确认收到；核实属实后：撤销涉事订阅者访问、停止更新与支持、 对冒用品牌者提交下架投诉，必要时公告澄清。若诈骗正在发生，请先向当地公安机关或平台举报——我们无法替代执法， 但会配合提供我们持有的记录。
4 · Guidance for deployers / 部署者建议
- Enable access control for public-facing rooms — watch code, whitelist or private mode (
accessMode=private).
面向公众的房间请开启准入（观看码 / 白名单 / 私有房）。 - Turn on viewer watermarks (room id + timestamp): anti-piracy and traceability for forged recordings.
开启观看端水印（房间号 + 时间戳）：防盗录并便于溯源。 - Keep audit logs (
audit_log/ webhooks) for after-the-fact review.
保留审计日志以便事后核查。 - Do not market CoStage as "anonymous, unmoderated, unlimited public broadcasting".
不要以"匿名、无人管、可大规模公开广播"作为卖点。
5 · What we do not promise / 不承诺的事
At our (small-team) scale we do not do content moderation, real-time deepfake detection, or 24×7 response — promising what we cannot deliver is worse than not promising. What we do: ship no synthetic-media features, state the prohibitions publicly, and act (with records) when reported.
以我们的规模，我们不做内容审核、不做实时深伪检测、不提供 7×24 响应—— 承诺做不到的事比不承诺更糟。我们会做的是：官方不提供合成功能、公开明示禁止、收到举报后处置并留痕。
