Holstein Inc. DBA Zerva · New York · Effective: on acceptance · Last updated October 12, 2026
1. Agreement. These Terms are a contract between Holstein Inc. DBA "Zerva" ("Zerva," "we") and the business that subscribes ("Customer," "you"). By completing signup or using the Service, you accept these Terms on behalf of your business and represent you are authorized to do so.
2. The Service. Zerva provides cloud-based booking and operations software for restaurants and service businesses, which may include floor management, a waitlist, reservations and appointments, customer SMS messaging, a website, and other modules you subscribe to (the "Service").
2.1 Where the Service is accessed. The Service is accessed at zrv.app, Zerva's platform domain. You and your staff sign in to the Service only on your own subdomain of zrv.app (for example, yourbusiness.zrv.app/admin); we will never ask you to sign in to the Service anywhere else. Your guest-facing pages and the links in the texts we send for you are also served from your zrv.app subdomain, or from a domain of yours that we host for you. Zerva's other official domains are getzerva.com (information and pricing) and signup.getzerva.com (signup and billing).
3. Subscription, modules & term. The Service is sold as one or more monthly module subscriptions selected at checkout. Your subscription begins on signup and automatically renews each billing period until canceled.
4. Fees, founding rate & auto-renewal.
5. Payment authorization. By providing a card or bank account, you authorize Zerva and its processor (Stripe) to charge that method on a recurring basis per Section 4. Failed payments may result in suspension after notice.
6. Cancellation & refunds. You may cancel any time from your account or by emailing support@getzerva.com; cancellation takes effect at the end of the current paid period. Fees are non-refundable except where required by law.
7. Your data; guest data. You retain ownership of your business data and your guests' data entered into the Service. You are the controller of your guest data and are responsible for the necessary consents (including SMS consent) to collect and message your guests.
8. SMS / messaging. You are solely responsible for obtaining lawful consent (TCPA/CTIA) from guests before messaging them through the Service, and for the content of those messages.
8.1 Messaging registration; limited agency. Carrier rules (10DLC and toll-free messaging) require that the business whose name appears in a text message be registered with The Campaign Registry ("TCR") and the mobile carriers. You appoint Zerva as your limited agent for the sole purpose of that registration, and authorize Zerva to: (a) submit your business's legal name, EIN or tax identifier, registered address, website, and an authorized contact to TCR, the mobile carriers, their aggregators, and any identity-vetting provider they require; (b) create, maintain, amend and withdraw messaging brands and campaigns on your behalf, and associate telephone numbers used for your account with them; and (c) use your business name, trade name and logo solely as needed to complete and maintain that registration.
You represent that the information you provide for this purpose is accurate and complete, that you are authorized to provide it and to bind the business it describes, and that you will notify Zerva within ten (10) days of any change to your legal name, EIN, address or ownership, since carriers may suspend messaging on registration data that no longer matches.
This appointment is limited to messaging registration. It creates no other agency, does not authorize Zerva to enter agreements or incur obligations in your name, and does not transfer your responsibilities under Sections 7 and 8: obtaining lawful consent from your guests and controlling the content of your messages remain yours.
Registration and vetting fees charged by TCR, the carriers or their vetting providers are passed through to you at cost and disclosed before they are incurred. Approval, message throughput, per-day limits and message filtering are determined by the carriers, not by Zerva; we do not guarantee that a registration will be approved, or that any message will be delivered.
This appointment ends when your subscription ends, and Zerva may then withdraw the registrations made under it and release the associated telephone numbers.
9. Acceptable use. No unlawful, infringing, or abusive use; no reselling the Service; no attempts to breach security.
10. Availability & support. We aim for high availability but do not guarantee uninterrupted service, and provide commercially reasonable support.
11. Disclaimers. THE SERVICE IS PROVIDED "AS IS" WITHOUT WARRANTIES OF ANY KIND TO THE FULLEST EXTENT PERMITTED BY LAW.
12. Limitation of liability. TO THE FULLEST EXTENT PERMITTED BY LAW, ZERVA'S TOTAL LIABILITY IS LIMITED TO THE FEES YOU PAID IN THE 12 MONTHS BEFORE THE CLAIM; NO INDIRECT OR CONSEQUENTIAL DAMAGES.
13. Governing law. New York law governs; venue in New York.
14. Changes. We may update these Terms on notice to your billing email; continued use after the effective date constitutes acceptance.
