Privacy Policy
Effective October 9, 2026
Privacy Policy
Trellis Stack LLC ("Trellis Stack," "we," "us") builds and operates Ivy, a membership and event management platform used by private clubs, event venues and private parties ("Venues"). This policy explains how we collect, use and protect personal information through trellisstack.com and Ivy.
Our role
When you apply to or join a Venue that uses Ivy, the Venue decides what information it collects from you and how it uses it. Trellis Stack processes that information on the Venue's behalf to operate the service, and the Venue's own privacy policy also applies to you.
When you contact us through trellisstack.com, or when a Venue's staff use Ivy, we handle that information for our own business as described here.
Information we collect
- Account and profile information: your name, email address, mobile phone number, date of birth, and the membership details you or your Venue provide.
- Membership and transaction records: applications, membership status and renewal dates, ticket and membership purchases, and event check-ins.
- Payment information: payments are processed by our payment processor. We do not store full payment card numbers.
- Messaging records: the text messages we send, their delivery status, and replies such as STOP and HELP. We also keep records of your consent to receive texts, including the exact consent wording you agreed to and when you agreed to it.
- Contact information you send us: submissions through the contact form on trellisstack.com.
- Technical information: IP address, device and browser type, and server log data.
How we use information
- To provide and operate Ivy for Venues and their members, including accounts, sign-in, memberships, ticketing, check-in and payments.
- To send account text messages, as described below.
- To respond to support requests and contact form submissions.
- To secure the service, prevent fraud and abuse, and verify age where a Venue requires it.
- To comply with the law and keep the records needed to show that we have.
Text messaging
Ivy sends account text messages on behalf of Venues to their members, applicants and staff. Each message begins with the name of the Venue it concerns. How each person opts in is described in the Text Messaging section of our Terms of Service and on our text message opt-in page.
These messages are limited to:
- one-time sign-in codes you request on a Venue's sign-in screen;
- application and membership status updates;
- purchase receipts and ticket confirmations;
- notices that an event you hold a ticket for was cancelled or moved;
- membership renewal and activation notices;
- account setup links for Venue staff;
- links to messages from a Venue's staff.
A mobile number is entered by you, by the Venue that adds you as staff, or by the applicant who lists you as a partner on a joint application. We never buy or rent phone numbers, and phone numbers are never obtained from third parties.
Trellis Stack does not send marketing text messages. A Venue may send its own event and promotional texts, but only to people who separately opted in to receive them. Those texts are governed by that Venue's own terms and privacy policy.
Message frequency varies. Msg & data rates may apply. Reply HELP for help or STOP to cancel. Full program terms are in the Text Messaging section of our Terms of Service.
Mobile information will not be shared with third parties or affiliates for marketing or promotional purposes. Sharing of information is allowed solely with subcontractors providing support services, such as customer service.
How we share information
We do not sell personal information. We do not sell or share your SMS opt-in data or personal information with third parties for marketing purposes. We share it only:
- with the Venue you applied to or joined;
- with service providers that run parts of Ivy for us — hosting, payment processing, text message and email delivery, and customer support — who may use it only to provide those services to us;
- when required by law, or when needed to protect the rights, safety and security of our users, Venues or the public.
All the above categories exclude text messaging originator opt-in data and consent; this information will not be shared with any third parties, other than the Venue the consent was given to and the carriers and providers that deliver the text messages.
How long we keep information
We keep account and transaction records for as long as a Venue uses Ivy, and afterward as needed for legal, tax and accounting purposes.
Records of text message consent and opt-out are kept permanently, so that we can always show which messages you agreed to receive and when you opted out.
Your choices
- Text messages: reply STOP to a Venue's account texts to stop them. Each Venue sends from its own number, so STOP ends that Venue's account texts, including sign-in codes, and no other Venue's. Reply START to that Venue's number to resume.
- Your information: you can update your details in your Ivy account, or contact your Venue or us to access or correct your information. Depending on where you live, you may have additional rights. Contact us to exercise them.
Security
We use reasonable technical and organizational measures to protect personal information against unauthorized access, loss or alteration. No system is perfectly secure.
Children
Ivy is not directed to anyone under 18, and we do not knowingly collect personal information from anyone under 18.
Changes to this policy
When we update this policy, we will post the new version here with a new effective date. If a change is material, we will also notify Venues and affected users.
