Privacy

Your information, explained.

This page describes the information the current C9 registration platform collects, where it goes, and how it is used to run an event.

Current as of 22 July 2026

1. Who handles your information

C9 Run Club is the event organizer operating this registration and ticketing platform. Privacy questions and requests can be sent to c9runclub@gmail.com.

2. Information the platform collects

When you register, the platform records the details entered for each runner:

  • full name, email address, WhatsApp number, area or city, and an optional Instagram username;
  • per-runner transactional WhatsApp choice and the separate optional marketing choice;
  • required agreement choices; and
  • permission from the primary booker when information is submitted for additional runners.

It also records operational information created by the service, including booking and payment status, booking references, ticket codes and status, check-in records, email and WhatsApp delivery status, provider event identifiers, and organizer audit records.

3. How the information is used

The current platform uses this information to create and manage registrations, enforce event capacity and checkout holds, verify payment status, issue individual QR tickets, deliver ticket emails and requested transactional WhatsApp confirmations, support entry check-in, and give authorized organizers the operational records needed to run the event.

Transactional WhatsApp consent and optional marketing consent are stored separately from the agreements required to register. Declining WhatsApp does not prevent registration or email delivery.

4. Payment information

C9 does not receive your card or UPI credentials.

Razorpay Checkout handles the payment interface. C9 stores the Razorpay order and payment identifiers, amount, currency, payment status, and limited processing records needed to verify and reconcile the booking.

5. Services used to operate the platform

The application currently uses Razorpay for checkout and payment verification, Supabase for protected application data, authentication, storage, and server functions, Resend for transactional ticket email, Meta WhatsApp Cloud API for requested transactional WhatsApp messages, and Vercel to run the website and application routes. Each provider processes the information needed for its part of the service.

7. Information about another runner

If you register another runner, the form requires you to confirm that you have permission to submit their information and request transactional delivery for them. Each runner receives an individual ticket by email and, when selected, at the WhatsApp number provided for them.

8. Retention and requests

Runner accounts include an in-app deletion control. A public deletion guide is also available at c9runclub.com/account-deletion for people who cannot access the app.

To ask C9 to access, correct, or delete information associated with a guest registration, email c9runclub@gmail.com with the event name, booking reference if available, and the registered email address. Do not send card details, a UPI PIN, an OTP, or a secure ticket link by email.
