CHI processes payments and personal data for live events, so we take security reports seriously and appreciate responsible disclosure.

If you believe you have found a security vulnerability in any CHI product or service (chi.app, web.chi.app, backstage.chi.app, the CHI mobile apps, or our APIs):

• Email: support@chi.app with the subject line SECURITY
• Include a description of the issue, steps to reproduce, and the potential impact
• If possible, include the affected URL/endpoint, request/response samples, and screenshots

Please do not open a public GitHub issue for security reports.

• We will acknowledge your report within 72 hours
• We will keep you informed while we investigate and remediate
• We will credit you for the finding if you would like (and the report is valid)

We ask that researchers:

• Do not access, modify, or delete data that is not their own
• Do not run automated scanners or load tests against production systems
• Do not attempt social engineering, phishing, or physical attacks against CHI staff, customers, or events
• Give us reasonable time to remediate before any public disclosure

Any CHI-operated system is in scope, including web applications, mobile apps, and public APIs. Third-party services we integrate with (payment providers, app stores) are out of scope — please report issues with those directly to the vendor.

Thank you for helping keep event-goers and organizers safe.
