+## Reading user feedback
+
+Users can submit feedback from the **Feedback** link in the nav (visible when logged in).
+Submissions are stored as JSON on the server:
+
+```
+/var/bincio/data/_feedback/
+  {handle}.json       ← one file per user, array of submissions
+  {handle}/           ← attached images
+```
+
+To read all feedback:
+
+```bash
+cat /var/bincio/data/_feedback/*.json | python3 -m json.tool
+```
+
+Per-user only:
+
+```bash
+cat /var/bincio/data/_feedback/pres.json | python3 -m json.tool
+```
