Terms of Service

Last updated: 2026-09-02

PLEASE READ SECTION 16 CAREFULLY. IT REQUIRES DISPUTES TO BE RESOLVED BY INDIVIDUAL BINDING ARBITRATION AND WAIVES YOUR RIGHT TO A JURY TRIAL AND TO PARTICIPATE IN A CLASS ACTION. YOU MAY OPT OUT OF SECTION 16 WITHIN 30 DAYS.

1. Who we are

Twilvi is a service of Slateford LLC, a New Mexico limited liability company. In these Terms, "Twilvi," "we," "us," and "our" mean Slateford LLC, and "you" means the person who agrees to these Terms. "Service" means the Twilvi website and the products and features available through it.

By creating an account or using the Service, you agree to these Terms and to our Privacy Policy. If you do not agree, do not use the Service.

2. Eligibility

You may use the Service only if all of the following are true:

  • You are at least 18 years old.
  • You are located in the United States.
  • You are not located in Illinois or Texas.

The Service is not offered to anyone in Illinois or Texas, and is not offered to anyone outside the United States. If you do not meet every requirement in this section, you are not permitted to use the Service, and we may suspend or terminate your account at any time. Sections 13 through 18 continue to apply to any use of the Service, whether or not you were eligible to use it.

3. Your account

You agree to provide complete and accurate account information and to keep it current so that we can communicate with you about your account. We may need to email you about your account, about changes to these Terms or our Privacy Policy, or about legal inquiries or complaints we receive concerning your use of the Service.

We may limit your access to the Service until we are able to verify your account information.

You are solely responsible and liable for your use of the Service and for all activity under your account, including maintaining the security of your account and your credentials. Do not share or misuse your credentials. Notify us immediately of any unauthorized use of your account or any other breach of security. If we believe your account has been compromised, we may suspend or disable it.

4. Your photographs

You keep ownership. You retain all rights you already have in the photographs and other material you upload ("Your Content"). These Terms do not transfer ownership of Your Content to us.

The permission you give us. You grant us a non-exclusive, worldwide, royalty-free license to host, store, copy, reproduce, modify, adapt, crop, analyze, display, and transmit Your Content, and to sublicense these rights to our service providers so that they may do so on our behalf, solely for the purpose of operating and providing the Service to you, including producing, printing, and shipping any product you order. This license ends when Your Content is deleted from the Service, except for copies already made in the ordinary operation of the Service and copies incorporated into a product you have ordered.

We do not sell Your Content. We do not sell your photographs, and we do not license them to anyone for advertising, marketing, or any purpose other than providing the Service to you.

What you promise us. You represent and warrant that, for every photograph and other material you upload:

  • You own it or otherwise have all rights necessary to upload it and to grant the license in this section; and
  • You have obtained the consent of every identifiable person appearing in it, and of the parent or legal guardian of any such person who is a minor, for that person's image to be uploaded to and processed by the Service as described in these Terms and in our Privacy Policy.

You are fully responsible for Your Content and for any harm resulting from it. We have not reviewed, and cannot review, all of the material uploaded to the Service.

5. Face grouping

The Service groups photographs by the people who appear in them. To do this, it generates and stores data derived from faces in the photographs you upload. The Service will not perform this processing unless you affirmatively consent to it. If you do not consent, the Service is not available to you. There is no alternative version of the Service that operates without this processing.

What is collected, how it is used, and how long it is kept are described in our Privacy Policy and, for Washington residents, in our Consumer Health Data Policy.

6. Products and purchases

Fourthwall, not Twilvi, is the seller of all products available through the Service. Fourthwall, Inc. is the merchant of record. All purchases are governed by Fourthwall's terms of service and privacy policy, which are linked on our checkout pages, and all payment, fulfillment, shipping, delivery, cancellation, refund, and tax matters are between you and Fourthwall. We are not a party to that transaction and have no responsibility or liability for it.

7. Acceptable use

You represent and warrant that your use of the Service:

  • Will comply with these Terms and with all applicable laws and regulations;
  • Will not be for any unlawful purpose or in furtherance of any unlawful activity;
  • Will not infringe or misappropriate the intellectual property, privacy, or publicity rights of any person;
  • Will not overburden, interfere with, disrupt, or attack the Service or any network or system we use;
  • Will not involve uploading or distributing malware or other harmful code;
  • Will not involve reverse engineering, decompiling, disassembling, or otherwise attempting to derive the source code of the Service; and
  • Will not involve renting, leasing, selling, reselling, or otherwise commercializing the Service or any data obtained from it.

8. Copyright

We respect the intellectual property rights of others and expect you to do the same.

Notices of claimed infringement. If you believe material on the Service infringes your copyright, send a notice under the Digital Millennium Copyright Act to our designated agent:

  • Designated agent: Copyright Agent
  • Slateford LLC
  • Address: 1209 Mountain Road Pl NE, Ste R, Albuquerque, NM 87110
  • Telephone: (505) 302-5125
  • Email: support@twilvi.com

Your notice must contain all of the elements required by 17 U.S.C. § 512(c)(3), including a physical or electronic signature, identification of the copyrighted work claimed to be infringed, identification of the material claimed to be infringing and information reasonably sufficient to permit us to locate it, your contact information, a statement that you have a good faith belief that the use is not authorized, and a statement, under penalty of perjury, that the information in the notice is accurate and that you are authorized to act on behalf of the copyright owner.

Repeat infringers. We will, in appropriate circumstances, terminate the accounts of users who are repeat infringers.

9. Our intellectual property

These Terms do not transfer any of our intellectual property or any third party's intellectual property to you. All right, title, and interest in and to the Service remains, as between you and us, solely with us. "Twilvi" and our logos are our trademarks. Using the Service does not grant you any right or license to reproduce or otherwise use any of our trademarks.

10. Third-party services

The Service relies on third parties, and you may access or purchase third-party services through it. Third-party services are not vetted, endorsed, or controlled by us. Your use of them is at your own risk and is governed by that third party's own terms and privacy policy. We are not responsible or liable for any third-party service.

11. Changes to these Terms

We may modify these Terms from time to time. If we do, we will post the amended Terms and update the "Last updated" date above, and, if we consider the changes material, we may notify you through the Service or by email. Changes apply going forward and, unless we say otherwise, are effective immediately. By continuing to use the Service after the amended Terms are posted, you agree to be bound by them. If you do not agree, stop using the Service.

12. Termination

We may terminate or suspend your access to all or any part of the Service at any time, with or without cause or notice, effective immediately. We may also remove any material that, in our reasonable opinion, violates these Terms or is otherwise harmful or objectionable. We have no obligation to provide a refund of any amount previously paid.

We may change, suspend, or discontinue the Service, or any part or feature of it, at any time and without notice.

You may stop using the Service at any time.

Sections 9, 10, and 13 through 18 survive termination, as does any license granted in Section 4 that by its terms continues.

13. Disclaimers

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE." TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, WE AND OUR SUPPLIERS AND LICENSORS DISCLAIM ALL WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING WITHOUT LIMITATION THE IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. WE MAKE NO WARRANTY THAT THE SERVICE WILL BE UNINTERRUPTED, TIMELY, SECURE, ERROR-FREE, OR THAT ANY MATERIAL WILL BE PRESERVED OR RECOVERABLE. YOU USE THE SERVICE AT YOUR OWN DISCRETION AND RISK.

14. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, WE AND OUR SUPPLIERS, PARTNERS, AND LICENSORS WILL NOT BE LIABLE, UNDER ANY THEORY OF CONTRACT, NEGLIGENCE, STRICT LIABILITY, OR OTHERWISE, FOR: (i) ANY INDIRECT, SPECIAL, INCIDENTAL, CONSEQUENTIAL, PUNITIVE, OR EXEMPLARY DAMAGES; (ii) LOSS OF PROFITS, GOODWILL, OR DATA; (iii) THE COST OF SUBSTITUTE PRODUCTS OR SERVICES; OR (iv) ANY AMOUNT IN THE AGGREGATE EXCEEDING THE GREATER OF ONE HUNDRED U.S. DOLLARS ($100) OR THE AMOUNTS YOU PAID US IN THE TWELVE (12) MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM. This applies even if we have been advised of the possibility of such damages. We are not liable for any failure or delay caused by matters beyond our reasonable control.

Nothing in these Terms limits liability for gross negligence, willful misconduct, or fraud, or any other liability that cannot be limited or excluded under applicable law.

15. Indemnification

You agree to indemnify, defend, and hold harmless Slateford LLC and its members, managers, officers, employees, contractors, and agents from and against any and all claims, demands, losses, liabilities, damages, costs, and expenses, including reasonable attorneys' fees, arising out of or related to: your use of the Service; Your Content; your breach of these Terms; or your violation of any law or of the rights of any person, including any claim brought by a person appearing in a photograph you uploaded.

16. Dispute resolution, arbitration, and class action waiver

PLEASE READ THIS SECTION CAREFULLY. IT AFFECTS YOUR LEGAL RIGHTS.

16.1 Informal resolution first. Before starting an arbitration, you agree to send us a written description of the dispute at support@twilvi.com and to try in good faith to resolve it for 60 days after we receive it.

16.2 Binding individual arbitration. Except as stated in Sections 16.5 and 16.6, you and we agree that any dispute, claim, or controversy arising out of or relating to these Terms or the Service will be resolved by binding individual arbitration, and not in court. The arbitration will be administered by JAMS under its Streamlined Arbitration Rules and Procedures and its Consumer Arbitration Minimum Standards, which are incorporated by reference. The arbitrator will issue a written decision. Judgment on the award may be entered in any court having jurisdiction. The Federal Arbitration Act governs the interpretation and enforcement of this Section 16.

The arbitration will be conducted by telephone, by videoconference, or on written submissions, or, if an in-person hearing is required, in the county where you reside.

16.3 Class action waiver. YOU AND WE AGREE THAT EACH MAY BRING CLAIMS AGAINST THE OTHER ONLY IN AN INDIVIDUAL CAPACITY, AND NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY PURPORTED CLASS, COLLECTIVE, CONSOLIDATED, OR REPRESENTATIVE PROCEEDING. The arbitrator may not consolidate more than one person's claims and may not preside over any form of class or representative proceeding. The arbitrator may award relief only in favor of the individual party seeking it and only to the extent necessary to provide relief warranted by that party's individual claim.

16.4 Jury trial waiver. YOU AND WE EACH WAIVE ANY RIGHT TO A JURY TRIAL in any proceeding arising out of or relating to these Terms or the Service.

16.5 Small claims. Either party may bring an individual action in small claims court for any dispute within that court's jurisdiction, instead of arbitration.

16.6 Your right to opt out. You may opt out of this Section 16. To do so, send written notice to support@twilvi.com within 30 days after you first agree to these Terms, stating your name, the email address on your account, and that you are opting out of arbitration. Opting out will not affect any other part of these Terms, and we will not terminate your account for opting out. If you opt out, Section 17 governs.

16.7 Severability. If the class action waiver in Section 16.3 is found to be unenforceable as to any claim or request for relief, then this entire Section 16 is void as to that claim or request for relief, and it must be brought in court under Section 17. The class action waiver in Section 16.3 is not severable from the rest of this Section 16. If any other provision of this Section 16 is found unenforceable, that provision is severed and the remainder of Section 16 stays in force.

16.8 Survival. This Section 16 survives termination of your account and of these Terms.

17. Governing law and venue

These Terms and any dispute arising out of or relating to them or to the Service are governed by the laws of the State of New Mexico, without regard to its conflict of law rules. For any dispute not subject to arbitration, you and we consent to the exclusive jurisdiction and venue of the state and federal courts located in Bernalillo County, New Mexico, and waive any objection to that forum.

18. Miscellaneous

These Terms, together with our Privacy Policy and our Consumer Health Data Policy, constitute the entire agreement between you and us concerning the Service, and supersede any prior agreement on that subject. If any part of these Terms is held unlawful, void, or unenforceable, that part is severable and does not affect the validity or enforceability of the rest. A waiver of any term or of any breach, in any one instance, does not waive that term or any subsequent breach. We may assign our rights and obligations under these Terms without condition; you may not assign yours without our prior written consent. Nothing in these Terms creates any third-party beneficiary right.
