+# Code of Conduct
+
+## Our standard
+
+Planer welcomes constructive participation. Contributors are expected to communicate professionally, critique ideas rather than people, respect differing experience and viewpoints, and keep technical discussions focused on improving the project.
+
+Unacceptable behavior includes harassment, discrimination, threats, deliberate disruption, publication of private information, or sustained personal attacks.
+
+## Scope
+
+This policy applies to repository issues, pull requests, reviews, discussions, and other spaces where a participant represents the Planer project.
+
+## Enforcement
+
+Report conduct concerns privately to the repository owner through their GitHub profile. Reports will be reviewed in confidence. Project maintainers may edit or remove content, reject contributions, restrict participation, or ban participants when behavior conflicts with this policy.
+
+Enforcement decisions will consider context, severity, recurrence, and impact on the community and project.
