+## Back up user diary via SensCritique v2 GraphQL API
+
+Set your username in `variables`. The `map` function used in the `jq` command converts the `dateDone` property from UTC to your local timezone.
+
+```sh
+$ curl -s -X "POST" "https://apollo.senscritique.com/" \
+     -H 'Content-Type: application/json; charset=utf-8' \
+     -d $'{
+        "query": "query UserDiary($isDiary:Boolean $limit:Int $offset:Int $universe:String $username:String! $yearDateDone:Int){user(username:$username){collection(isDiary:$isDiary limit:$limit offset:$offset universe:$universe yearDateDone:$yearDateDone){products{id universe category title originalTitle alternativeTitles yearOfProduction url otherUserInfos(username:$username){dateDone rating}}}}}",
+        "variables": {
+                "isDiary": true,
