+# JIGAIDO
+
+> Named after Nanami Kento's Cursed Technique restriction. Suppresses power during normal hours, exerts it during overtime.
+
+A lightweight bounty tracker for Telegram groups and individuals. Track obligations, deadlines, and tasks with optional reminders.
+
+## Features
+
+- **Group bounties**: Each Telegram group has its own bounty list
+- **Personal bounties**: Private DM bounty list for individuals
+- **Admin-only posting**: Only group admins can add/update/delete bounties
+- **Universal tracking**: Any member can track bounties to their personal list
+- **Due date reminders**: Daily cron notifies users when bounties are due within 7 days
+- **Free-form dates**: Natural language due dates (`"tomorrow"`, `"in 3 days"`, `"april 15"`)
+- **Link deduplication**: No duplicate links within the same group
+- **Zero infrastructure**: SQLite + Python, deploys on any $5 VPS
