 - **Tracking**: Users can track any bounty (group or personal) to their tracking list.
 - **Due dates**: Free-form text (`"april 15"`, `"in 3 days"`, `"tomorrow"`) parsed at add time, stored as Unix timestamp. If unparseable, stored as `NULL`.
 - **Links**: Optional. If provided, stored with the bounty.
-- **Informed by**: Every bounty stores the Telegram username of who posted/added it.
+- **Informed by**: Every bounty stores the user ID of who posted/added it.

 ### Storage Design
 
-**File structure (`data/users/{telegram_user_id}.json`):**
+**File: `data/{group_id}/group.json`**
 
 ```json
 {
-  "user_id": 123,

-  "personal_bounties": [

     {

       "link": "https://github.com/example/repo/issues/1",
       "due_date_ts": 1735689600,
-      "group_id": null,
-      "informed_by_username": "alice",
       "created_at": 1735603200
     }
   ],
-  "tracked_bounties": [
-    {"bounty_id": 5, "group_id": -1001, "created_at": 1735600000},
-    {"bounty_id": 3, "group_id": null, "created_at": 1735590000}
+  "next_id": 2
+}
+```
+
+**File: `data/{group_id}/{user_id}.json`**
+
+```json
+{
+  "tracked": [
+    {"bounty_id": 1, "created_at": 1735600000}
   ]
 }
 ```
 
+**File: `data/{user_id}/user.json`**
+
+```json
+{
+  "bounties": [
+    {
+      "id": 1,
+      "text": "Personal task",
+      "link": null,
+      "due_date_ts": 1735689600,
+      "created_at": 1735603200
+    }
+  ],
+  "next_id": 2
+}
+```
+
 **Key design decisions:**
 
-1. **Single file per user** — Personal bounties live in the creator's file. Group bounties also live in creator's file with `group_id` set.
-2. **Bounty IDs are sequential integers per file** — Not global. Each user's file has its own ID counter.
+1. **Group-isolated storage** — Each group has its own directory. No cross-group access.
+2. **Bounty IDs are sequential per group.json** — Not global. Each group's file has its own ID counter.
 3. **Atomic writes** — Uses `tempfile` + `rename` for safe writes.
 4. **No reminders in v1** — Dropped for simplicity.
