+# Safety Standards
+
+## Child Sexual Abuse and Exploitation (CSAE) Policy
+
+Coho is a fast, offline-first Mastodon client designed to connect users to the Fediverse. As a client application, Coho does not host any user-generated content directly. However, we are deeply committed to maintaining a safe environment and strictly prohibit any use of our application to facilitate, distribute, or access Child Sexual Abuse Material (CSAM) or any form of Child Sexual Abuse and Exploitation (CSAE).
+
+### Zero Tolerance Policy
+
+We have a zero-tolerance policy against CSAE. Any use of the Coho app to promote, facilitate, or share content related to the sexual abuse or exploitation of children is strictly prohibited. 
+
+### Content Moderation and Reporting
+
+Because Coho connects to third-party Mastodon servers, content moderation is primarily handled by the administrators of those individual servers. However, Coho enforces safety at the client level by:
+
+- **Blocking Known Offending Instances**: Coho reserves the right to block connections to any Mastodon instances that are known to host or tolerate CSAM or other forms of CSAE.
+- **Reporting Mechanisms**: Users are encouraged to report any instances of CSAE encountered on the Fediverse. These reports should be directed to:
+  1. The administrator of the instance hosting the content.
+  2. The appropriate law enforcement agencies, such as the [National Center for Missing & Exploited Children (NCMEC)](https://www.missingkids.org/) in the United States, or local equivalent authorities.
+  3. Coho developers at jgw9617@gmail.com, so we may evaluate whether the offending instance should be disconnected or blocked from the client.
+
+### Enforcement
+
+Violations of this policy will result in immediate action, which may include:
+- Blocking access to the offending instances from within the Coho app.
+- Cooperating fully with law enforcement and reporting authorities in any investigations related to CSAE.
+
+### User Responsibility
+
+Users of Coho are expected to adhere to the rules and policies of the Mastodon instances they connect to, as well as local and international laws. Engaging in any activity involving CSAE is a severe criminal offense and will not be tolerated.
+
+For more information on our community standards and how we ensure a safe environment, please refer to our [Code of Conduct](./CODE_OF_CONDUCT.md).
