What this is

A self-paced live polling web app for the Hi-Acts 3rd Network Meeting at DESY Hamburg (10 June 2026).

Attendees scan a QR code, answer 10 questions on their phone, and can view live results afterwards. Results update automatically every 2.5 seconds.

How to run locally (for testing)

cd conference_poll
pip3 install -r requirements.txt
python3 app.py

Then open http://localhost:5001 in a browser.

Deployment instructions

Recommended setup (Bluehost VPS or equivalent)

1. Upload the entire conference_poll/ folder to the server

2. Install dependencies:

   pip3 install -r requirements.txt
   pip3 install gunicorn
   

3. Run with Gunicorn (production-grade server):

   gunicorn -w 2 -b 0.0.0.0:80 app:app
   

   Or on port 443 with SSL if HTTPS is configured.

4. The app will be accessible at the server's public IP or domain.

Before go-live checklist

• Generate a new QR code pointing to the live URL (e.g. https://poll.txproducts.de)
• Replace static/attend_qr.png with the new QR code image
• Update the URL pill in templates/join.html (search for poll.txproducts.de)
• Restrict access to /admin so it is not publicly accessible (basic auth or IP whitelist)
• Consider adding a database for persistent storage (see note below)

---

Important: data persistence

Currently all responses are stored in memory. If the server restarts during the event, all data is lost.

For production, the answers dictionary in app.py should be replaced with a simple SQLite or PostgreSQL database. The relevant section is clearly marked in app.py with the comment "IN-MEMORY DATA STORE".

---

Security notes

• The /admin page has no authentication. Restrict it at the server level before deployment.
• The Flask secret_key in app.py should be changed to a long random string for production.
• The demo routes (/demo/stream, /demo/status, /submit_demo) are safe to leave in but can be removed if preferred.

Changing questions (content owner: TXproducts)

Questions are defined in app.py in the QUESTIONS list. The web dev team does not need to touch these. The TXproducts team manages question content directly.

After any question change, the QUESTIONS array in templates/display.html (inside the <script> tag) must also be updated to match. Both lists are clearly commented.
