72H Bomb Pad โ€” End-to-End Encrypted Collaborative Notepad

The 72H Bomb Pad is a browser-based collaborative notepad that self-destructs exactly 72 hours after the last edit. It uses AES-256-GCM end-to-end encryption so that not even the site owner can read your content. The encryption key exists only in the URL hash (#) and is never sent to the server โ€” the database stores only an encrypted blob. Multiple users can edit simultaneously via Supabase Realtime, with changes reflected instantly on every connected screen. It is ideal for trip planning, group shopping lists, short team sprints, and urgent meeting notes. If nobody writes anything for 72 hours, the pad automatically self-destructs.

Common Use Cases

๐Ÿ•๏ธ
Trip Planning
Share travel plans, restaurant lists, and packing checklists in one collaborative pad instead of a group chat. Every time someone adds an item, the 72-hour timer resets automatically.
๐Ÿ›’
Group Shopping Lists
Create a shared shopping list with family or roommates that updates in real time for all viewers. The pad auto-expires when the list is no longer needed, keeping things tidy without manual deletion.
๐Ÿ’ก
Short Team Sprints
Freely share and co-edit brainstorming ideas with teammates during a short sprint period. When the project ends, the pad self-destructs automatically without leaving behind stale content.
๐ŸŽฏ
Urgent Meeting Notes
Organize time-sensitive agendas and action items that need a resolution within 72 hours. Download the notes after the meeting, then let the pad expire on its own.

How to Use

  1. 1
    Open the pad
    Opening this page automatically generates a unique pad ID and AES-256 encryption key embedded in the URL. No login or installation is required โ€” the pad is ready to use instantly.
  2. 2
    Share the full URL
    Copy the entire URL including the # part and send it to your collaborators. Only those with the same full link can access and decrypt the pad content.
  3. 3
    Collaborate in real time
    Any edit is encrypted and synced via Supabase Realtime, reflected instantly on every connected screen. Each edit also resets the 72-hour countdown timer from the beginning.
  4. 4
    Evacuate before 1 hour remains
    When less than 1 hour remains, a warning banner appears. Click the download button to save the content as a text file before the pad self-destructs permanently.
