Privacy Policy

Last updated June 4, 2026

Overview

Plus One ("Plus One", "we", "us") provides event-organization software for curators, promoters, venues, and brands ("Organizers") to manage guestlists, page builders, communications, and door check-in. This policy describes what personal information we collect from Organizers and from guests who interact with Organizer pages, how we use it, and the choices you have.

Information We Collect

When you use Plus One, we may collect:

  • Account information for Organizers: name, email address, organization name, and login credentials.
  • Guest information that an Organizer collects or enters about you (for example on an RSVP page, a guestlist, or a personalized invite link): name, email address, mobile phone number, and any additional fields the Organizer chooses to collect (for example company, role, dietary preferences, +1 details). To help Organizers manage their lists, some fields (such as a likely-gender suggestion) may be generated automatically from the information provided; Organizers can edit or clear these.
  • Event interaction data: RSVP status, check-in time at the door, message history with the Organizer, and whether you opened or clicked the Organizer's email and SMS messages (so the Organizer can see whether their messages are reaching guests).
  • Technical data: IP address, device and browser type, and cookies used to keep you signed in and to measure aggregate usage. For Organizer accounts we also keep a sign-in history (the date, IP address, and device of successful logins) to help secure the account and let account administrators review recent activity. For Organizers who use our iOS app and turn on notifications, we also store a device push token and their notification preferences so we can send (and let them control) push notifications.
  • Prospect information you submit through our contact or early-access forms: your name, email address, phone number, organization, and what you tell us about your events, so we can follow up with you.

Text Messaging for Guestlist Purposes

Phone numbers collected through a Plus One guestlist or RSVP page are used to deliver SMS messages related to that event, including: RSVP confirmations, event details (address, start time, dress code), day-of reminders, changes or cancellations, door check-in coordination, and follow-ups from the Organizer. By submitting your phone number on an Organizer's page, you consent to receive these messages from Plus One on the Organizer's behalf.

Message frequency varies by event. Message and data rates may apply. You can opt out at any time by replying STOP to a message you have received; you can also reply HELP for assistance, or email hello@useplusone.com. Opting out of SMS will not affect other event-related communications you have separately agreed to, such as email.

We do not use phone numbers collected for one Organizer's event to send messages on behalf of a different Organizer, and we do not sell phone numbers or share them with marketers. SMS messages are delivered through trusted third-party carriers and messaging providers (such as Twilio and Infobip), who act as data processors on our behalf.

How We Use Information

We use the information we collect to:

  • Operate and improve the Plus One platform.
  • Enable Organizers to communicate with their guests by email and SMS for guestlist purposes, as described above, and show Organizers whether those messages were delivered, opened, or clicked.
  • Provide check-in functionality at the door and reconcile RSVPs with attendance.
  • Send push notifications to Organizers on their iOS devices when they have turned them on.
  • Detect and prevent fraud, abuse, and security incidents.
  • Comply with legal obligations.

Sharing

We share guest information with the Organizer whose page was used to collect it. We share information with service providers (hosting, analytics, email and SMS delivery, and mobile push notification delivery) under contracts that require them to protect the data and use it only for the services they provide to us. To send push notifications to an Organizer's own devices in our iOS app, we use Apple's Push Notification service, which receives the device's push token and the notification content. We may disclose information if required by law or to protect the rights, safety, or property of Plus One, our users, or others.

Retention

We retain account and guest information for as long as the Organizer's account is active and for a reasonable period afterward to support audit, dispute resolution, and legal requirements. Device push tokens are kept until you turn off notifications, Apple invalidates the token, or your account is deleted. You may request deletion at any time by emailing hello@useplusone.com.

Your Choices

You can opt out of SMS at any time by replying STOP. You can request access to, correction of, or deletion of your personal information by contacting us. Depending on where you live you may have additional rights under applicable law (for example, the GDPR or CCPA).
