Overview

Who's In? ("we", "us", "our") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, and safeguard your personal information when you use our event coordination platform.

We follow data minimization principles and comply with applicable global data protection laws including:

  • General Data Protection Regulation (GDPR) - European Union
  • California Consumer Privacy Act (CCPA) - United States
  • Personal Data Protection Law (UU PDP) - Indonesia
  • Personal Data Protection Act (PDPA) - Singapore
  • Other applicable regional privacy regulations

Information We Collect

We collect only the minimum information necessary to provide our services:

Account Information

  • Email address: Required for account creation and event notifications
  • Name: Displayed to organizers and optionally to other attendees (as "First L.")
  • Phone number: Optional, for WhatsApp notifications if you enable them
  • Country: Optional, for time zone purposes

Event Data

  • Events created: Event details you provide (title, description, location, date/time)
  • RSVP history: Events you've registered for and attendance status
  • Check-in data: If enabled by organizer, arrival confirmations

Technical Data

  • Device information: Browser type, operating system (for compatibility)
  • Usage analytics: Anonymous, aggregated data about feature usage
  • Error logs: Technical errors to improve service reliability

What We Don't Do

  • We never sell your personal information to third parties
  • We never share your data for advertising or marketing
  • We never use your data for profiling or targeted ads
  • We never track your location without explicit consent
  • We never show ads — not now, not ever

AI Agent Access

NEW

Who's In? is "AI Agent Ready," meaning AI assistants (like ChatGPT, Claude, and Gemini) can discover and interact with public events through our API.

What Information AI Agents Can Access:

  • Public event details only: Title, description, date, time, location, and capacity
  • Real-time availability: Number of spots left and waitlist status
  • No attendee information: AI agents never see who's attending your event

Human-in-the-Loop Safety:

When an AI agent initiates an RSVP on behalf of a user, that user must explicitly confirm via email before the RSVP is processed. AI agents cannot RSVP without human confirmation. This protects against AI errors and ensures user consent.

Private Events:

Only events marked as "Public" are discoverable by AI agents. Private events remain completely hidden from AI agent discovery and our public API.

For technical details about our AI agent integration, see our AI Agent Integration blog post or our OpenAPI specification.

Data Sharing & Recipients

We share your information only in these limited circumstances:

Event Organizers

When you RSVP to an event, organizers can see:

  • Your name and RSVP status

  • Check-in status (if enabled)

If attendee list visibility is enabled:

  • Your name displayed as "First L." (privacy-preserving format)
