-### Cache Clearing
+### Cache & P2P Data
+
+#### Clear Browser Cache
+- **API/IPC:** `settings.clearBrowserCache()` → invokes `ipcMain.handle('settings-clear-cache')`
+- **Wipes (Chromium session only):**
+  - Cookies
+  - LocalStorage / SessionStorage
+  - IndexedDB
+  - Service Workers
+  - Cache Storage
+  - HTTP cache (`session.clearCache()`)
+- **Does NOT touch:** `ipfs/`, `hyper/`, `ensCache.json`, identity files
+
+#### Reset P2P Data
+- **API/IPC:** `settings.resetP2P({ resetIdentities?: boolean })` → `ipcMain.handle('settings-reset-p2p')`
+- **Default behavior (`resetIdentities: false`):**
+  - Clears P2P caches: `ipfs/` (except `libp2p-key`), `hyper/` (except `swarm-keypair.json`)
+  - Removes `ensCache.json`
+  - ✅ **Preserves identities:** `ipfs/libp2p-key`, `hyper/swarm-keypair.json`
+- **Full wipe (`resetIdentities: true`):**
+  - Deletes **all** P2P data including identity files
+  - New identities will be generated on next launch
 
-- `settings.clearCache()`
-- Wipes:
-  - Electron session (cookies, storage)
-  - P2P caches (`ipfs/`, `hyper/`, `ensCache.json`)
