Terms of Service

Last updated May 28, 2026

1. Acceptance of These Terms

These Terms of Service ("Terms") are a binding legal agreement between you and Plus One, operated by Wrong Door Labs LLC, doing business as Plus One Labs ("Plus One", "we", "us", or "our"), and govern your access to and use of the Plus One platform, websites, applications, APIs, and related services (collectively, the "Services"). By creating an account, accessing or using the Services, clicking to accept these Terms, or submitting information on a Plus One guestlist or RSVP page, you agree to be bound by these Terms. If you do not agree, you may not use the Services.

If you use the Services on behalf of an organization, you represent and warrant that you have the authority to bind that organization to these Terms, and "you" and "Organizer" refer to that organization. You must be at least 18 years old and legally capable of entering into a contract to use the Services.

2. Definitions

  • "Organizer" means a curator, promoter, venue, brand, or other party that creates an account to use the Services to run events.
  • "Guest"means an individual who interacts with an Organizer's pages or receives communications sent through the Services on the Organizer's behalf.
  • "Organizer Content" means any content, data, contact information, branding, and materials an Organizer uploads, imports, or submits to the Services.
  • "Guest Data" means personal information relating to Guests that is collected or processed through the Services.

3. The Services

Plus One provides software that lets Organizers build event pages, manage guestlists and a guest CRM, send communications by email and SMS for guestlist purposes, run door check-in, and access related tools. Guests interact with Plus One primarily through Organizer-built pages and through messages sent on an Organizer's behalf. We may add, change, suspend, or discontinue any part of the Services at any time, with or without notice.

4. Accounts and Security

Organizers must provide accurate, current, and complete information when creating an account and keep it up to date. You are responsible for safeguarding your credentials and for all activity that occurs under your account, whether or not authorized by you. You must notify us promptly of any unauthorized use or security breach. We may suspend or terminate accounts that we reasonably believe have been compromised or are being used in violation of these Terms.

5. Fees and Payment

Certain features of the Services are offered for a fee. By selecting a paid plan or feature, you agree to pay all applicable fees, which are non-refundable except as required by law or expressly stated by us. Payments are processed by third-party payment providers (such as Stripe), and your use of those services is subject to their terms. Unless otherwise stated, fees are exclusive of taxes, and you are responsible for all applicable taxes. Subscription fees recur until cancelled, and we may change pricing prospectively upon reasonable notice. If you owe amounts that are past due, we may suspend the Services and pursue collection.

6. Organizer Responsibilities (Imported and CRM Contacts)

When an Organizer uploads, imports, syncs, or otherwise adds contact information to Plus One — including phone numbers — that did not originate from a Plus One guestlist or RSVP page, the Organizer represents and warrants that:

  • Each contact has given the Organizer prior express consent to receive event-related communications from the Organizer, including SMS where a mobile phone number is provided;
  • The Organizer is authorized to provide each contact's information to Plus One for the purpose of delivering those communications on the Organizer's behalf;
  • The consent obtained is sufficient under applicable law (including the TCPA and analogous state and international laws) for the category of communications the Organizer intends to send; and
  • The Organizer maintains records of consent and will honor opt-out requests (including STOP replies and any direct opt-out received outside of Plus One) promptly across all of its messaging.

Plus One may require Organizers to confirm these representations at the point of import or send, and may refuse, throttle, or remove any contacts or messages at our discretion. Organizers remain solely responsible for the lawfulness of the contacts they bring to the Services and the content of messages they send.

7. Acceptable Use

You agree not to use the Services to:

  • send unsolicited messages or otherwise violate applicable telecom and consumer-protection laws (including the TCPA, CAN-SPAM, CTIA messaging principles, and equivalent rules in your jurisdiction);
  • upload or message contacts you did not obtain valid consent for;
  • send content involving SHAFT categories (sex, hate, alcohol to minors, firearms, tobacco/cannabis) where prohibited, or any unlawful, fraudulent, deceptive, harassing, defamatory, or infringing content;
  • impersonate any person or misrepresent your affiliation;
  • attempt to gain unauthorized access to, probe, scrape, reverse engineer, or disrupt the Services or their underlying systems;
  • resell, sublicense, or provide the Services to third parties except as we expressly permit; or
  • use the Services in any manner that could damage, disable, or impair our infrastructure or interfere with any other party's use.

We may investigate suspected violations and cooperate with law enforcement. Violation of this section is a material breach of these Terms.

8. SMS Messaging Terms (Guestlist Use)

Plus One uses SMS to support event guestlists. The following terms apply to text messages sent through the Services:

  • Consent.By submitting your mobile number on a Plus One guestlist or RSVP page, you consent to receive SMS messages from Plus One on the Organizer's behalf for that event. Messages are used for guestlist purposes only — confirmations, event details, reminders, changes or cancellations, door check-in, and Organizer follow-ups.
  • Frequency.Message frequency varies by event and by the Organizer's communications.
  • Costs. Message and data rates may apply, depending on your wireless plan.
  • Opt out. Reply STOP to any Plus One SMS to stop receiving further messages. Reply HELP for help, or email hello@useplusone.com.
  • Carriers. Carriers are not liable for delayed or undelivered messages. Delivery is not guaranteed.
  • No marketing resale. We do not use your phone number for marketing unrelated to the event you signed up for, and we do not share or sell it with third parties for their own marketing.

9. Organizer Content and Data

As between you and Plus One, Organizers retain ownership of Organizer Content. You grant Plus One a worldwide, non-exclusive, royalty-free license to host, store, reproduce, modify (for formatting and display), transmit, and display Organizer Content as necessary to provide, secure, and improve the Services, and to create de-identified or aggregated data that does not identify you or any Guest. You are solely responsible for Organizer Content and represent that you have all rights necessary to grant this license. Plus One's handling of personal information is described in our Privacy Policy.

10. Data Protection

With respect to Guest Data, the Organizer is the controller and Plus One acts as a processor (or service provider) processing such data on the Organizer's behalf and on its documented instructions, solely to provide the Services. The Organizer is responsible for providing all required notices to and obtaining all required consents from Guests, and for the lawful basis of any processing it directs. Where required, the parties will enter into a separate Data Processing Addendum, which is incorporated into these Terms by reference when executed.

11. Plus One Intellectual Property

The Services, including all software, designs, text, graphics, the "+1" mark, and other materials (excluding Organizer Content), are owned by or licensed to Plus One and are protected by intellectual property laws. We grant you a limited, revocable, non-exclusive, non-transferable license to access and use the Services for your internal business purposes during the term, subject to these Terms. All rights not expressly granted are reserved. You may not copy, modify, distribute, sell, or create derivative works of the Services except as permitted by law.

12. Feedback

If you provide suggestions, ideas, or feedback about the Services, you grant Plus One a perpetual, irrevocable, worldwide, royalty-free license to use and incorporate it without restriction or obligation to you.

13. Third-Party Services

The Services integrate with or rely on third-party services (for example, payment, messaging, email, hosting, and analytics providers). We are not responsible for third-party services, and your use of them may be subject to their separate terms. Third-party services are provided "as is" and we disclaim all liability arising from them.

14. Confidentiality

Each party may receive non-public information of the other ("Confidential Information"). The receiving party will use Confidential Information only to perform under these Terms, protect it with reasonable care, and not disclose it except to those who need to know and are bound by similar obligations. This does not apply to information that is public, independently developed, or rightfully received from a third party, or that is required to be disclosed by law.

15. Suspension and Termination

You may stop using the Services at any time. We may suspend or terminate your access immediately and without liability if you breach these Terms, create risk or legal exposure for us, fail to pay fees when due, or if we discontinue the Services. Upon termination, your right to use the Services ceases, and we may delete Organizer Content after a reasonable period, subject to legal retention requirements. Sections that by their nature should survive termination (including ownership, fees accrued, disclaimers, limitation of liability, indemnification, and dispute resolution) will survive.

16. Beta Notice

Some features may be offered on a beta, preview, or evaluation basis. Such features are provided "as is", may change, break, or be removed without notice, and are excluded from any service commitments or warranties.

17. Disclaimer of Warranties

THE SERVICES ARE PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, OR STATUTORY, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE SERVICES WILL BE UNINTERRUPTED, SECURE, OR ERROR-FREE, THAT DEFECTS WILL BE CORRECTED, OR THAT ANY MESSAGE WILL BE DELIVERED. SOME JURISDICTIONS DO NOT ALLOW CERTAIN DISCLAIMERS, SO SOME OF THE ABOVE MAY NOT APPLY TO YOU.

18. Limitation of Liability

TO THE FULLEST EXTENT PERMITTED BY LAW, PLUS ONE AND ITS AFFILIATES, OFFICERS, EMPLOYEES, AND SERVICE PROVIDERS WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, REVENUES, DATA, GOODWILL, OR BUSINESS INTERRUPTION, ARISING OUT OF OR RELATED TO YOUR USE OF (OR INABILITY TO USE) THE SERVICES, WHETHER BASED IN CONTRACT, TORT, OR ANY OTHER THEORY, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

IN NO EVENT WILL PLUS ONE'S TOTAL AGGREGATE LIABILITY ARISING OUT OF OR RELATED TO THESE TERMS OR THE SERVICES EXCEED THE GREATER OF (A) THE TOTAL AMOUNTS YOU PAID TO PLUS ONE FOR THE SERVICES IN THE TWELVE (12) MONTHS PRECEDING THE EVENT GIVING RISE TO THE CLAIM, OR (B) ONE HUNDRED U.S. DOLLARS ($100). THESE LIMITATIONS ARE AN ESSENTIAL BASIS OF THE BARGAIN BETWEEN THE PARTIES.

19. Indemnification

Each Organizer agrees to defend, indemnify, and hold harmless Plus One and its affiliates, officers, employees, and service providers from and against any claims, damages, liabilities, fines, penalties, losses, costs, and expenses (including reasonable attorneys' fees) arising out of or related to: (a) the Organizer's breach of these Terms, including the representations in the "Organizer Responsibilities" section above; (b) the Organizer's collection, upload, or use of contact information without appropriate consent; (c) the content of messages or Organizer Content the Organizer sends, uploads, or causes to be sent through the Services; (d) the Organizer's events themselves; or (e) the Organizer's violation of any applicable law, including telecom and consumer-protection laws such as the TCPA, CAN-SPAM, analogous state laws, GDPR, and CCPA. Plus One may, at its option, assume the exclusive defense and control of any matter subject to indemnification, and the Organizer agrees to cooperate with that defense.

20. Dispute Resolution; Arbitration; Class Action Waiver

Please read this section carefully — it affects your legal rights. Except for claims that may be brought in small-claims court and claims for injunctive relief relating to intellectual property, any dispute arising out of or relating to these Terms or the Services will be resolved by final and binding arbitration on an individual basis, administered under the rules of a recognized arbitration provider, seated in California. YOU AND PLUS ONE WAIVE THE RIGHT TO A TRIAL BY JURY AND THE RIGHT TO PARTICIPATE IN A CLASS, COLLECTIVE, OR REPRESENTATIVE ACTION. If the class-action waiver is found unenforceable, the remainder of this section will not apply to that dispute. You may opt out of arbitration by emailing us within 30 days of first accepting these Terms.

21. Governing Law

These Terms are governed by the laws of the State of California, without regard to its conflict-of-laws rules. Subject to the arbitration section above, the state and federal courts located in California will have exclusive jurisdiction over any disputes not subject to arbitration, and you consent to personal jurisdiction there.

22. Force Majeure

Plus One will not be liable for any delay or failure to perform resulting from causes beyond our reasonable control, including acts of God, outages, carrier or third-party failures, labor disputes, or governmental action.

23. Changes to These Terms

We may update these Terms from time to time. If we make material changes, we will provide reasonable notice (for example, by email or in-product notice). Your continued use of the Services after changes take effect constitutes acceptance of the updated Terms.

24. General

These Terms, together with any policies and addenda referenced herein, constitute the entire agreement between you and Plus One regarding the Services and supersede all prior agreements. You may not assign these Terms without our prior written consent; we may assign them freely, including in connection with a merger, acquisition, or sale of assets. If any provision is held unenforceable, the remaining provisions remain in effect. Our failure to enforce any right is not a waiver. There are no third-party beneficiaries. Notices to you may be provided through the Services or by email; notices to us must be sent to the contact below.
