+# Cache System
+
+LunaticChat includes a system that automatically caches phrases from Japanese romanization conversion to both memory and disk.
+
+For information on Japanese romanization conversion, see [here](../player/japanese-romanization.md).
+
+## Memory Cache
+
+LunaticChat caches converted phrases in memory, allowing for fast responses when the same phrase is requested again.
+
+This cache is temporary and is saved to disk cache at server restart or at configured intervals.
+
+## Disk Cache
+
+LunaticChat periodically saves the contents of the memory cache to disk. This allows the cache contents to be retained even after server restarts.
+
+The file used for disk cache can be [changed in the configuration](configuration.md#cachefilepath).
+
+## Cache Release
+
+Memory cache is automatically released by the JVM's garbage collection after being cached to disk.
+
+Disk cache can be released by manually deleting the file. LunaticChat will recreate the cache file on restart.
+
+::: warning About Purge Functionality
+
+LunaticChat does not implement a cache purge feature.
+
+This is because allowing players to manipulate the host's file system is not desirable from a security perspective.
+
+:::
+
+## Cache Version
+
+The file used for disk cache includes a `version` field, which handles changes to the cache format due to LunaticChat version updates.
+
+If the version does not match, LunaticChat recognizes the cache file as **an old format cache**, ignores its contents, and recreates it in the new format.
+
+```json
+{"version":"1","entries":{}}
+```
