+# Privacy Policy — Discord Matrix Bridge
+
+## 1. Purpose and Scope
+
+This Privacy Policy describes how data is handled when using the Discord Matrix bridge (“the Bridge”). The Bridge enables message synchronization between a Matrix room hosted on our infrastructure and a corresponding Discord server or channel.
+
+This policy applies solely to the operation of the Bridge and the Matrix-side infrastructure operated by us. It does not govern Discord’s own services or data handling practices.
+
+## 2. Matrix Side Infrastructure
+
+The Matrix homeserver and bridge services are self-hosted on infrastructure located in South Korea and are operated by us.
+
+We do not collect, analyze, profile, or monetize user data. Data is processed only to the extent technically necessary to provide message delivery between Matrix and Discord.
+
+## 3. Data Processed
+
+The Bridge may transiently process the following data solely for message synchronization purposes:
+
+- Message content
+- Message timestamps
+- Sender identifiers (usernames, IDs, or Matrix IDs as required for bridging)
+- Room or channel identifiers
+
+No additional personal data is intentionally collected.
+
+## 4. Data Storage and Retention
+
+- The Bridge does not retain logs, message content, or metadata beyond what is required for normal Matrix server operation and real-time message delivery.
+- No separate databases, analytics systems, or long-term archives are maintained by the Bridge operator.
+
+Any data stored as part of standard Matrix room history is subject to the configuration and retention policies of the Matrix homeserver.
+
+## 5. Discord Data Handling
+
+Messages that are bridged to Discord are transmitted to Discord’s infrastructure and are thereafter processed in accordance with [Discord’s Privacy Policy](https://discord.com/privacy) and [Terms of Service](https://discord.com/terms).
+
+We have no control over how Discord stores, processes, or retains data once it reaches Discord’s systems.
+
+## 6. Data Sharing
+
+- No data is shared with third parties other than Discord as an inherent function of the bridge.
+- No data is sold, sublicensed, or disclosed for advertising, analytics, or tracking purposes.
+
+## 7. Legal Basis
+
+Data processing performed by the Bridge is limited to what is strictly necessary for the legitimate purpose of enabling cross-platform communication between Matrix and Discord.
+
+## 8. User Awareness
+
+By participating in a bridged room, users acknowledge that:
+
+- Messages sent on Matrix may appear on Discord, and
+- Messages sent on Discord may appear on Matrix, subject to the respective platform’s policies and technical limitations.
+
+## 9. Changes to This Policy
+
+This Privacy Policy may be updated to reflect changes in infrastructure, legal requirements, or bridge functionality. Material changes will be communicated where reasonably possible.
+
+## 10. Contact
+
+For questions or concerns regarding this Privacy Policy or the operation of the Bridge, please contact the server administrators.
