Terms of Service

1. Eligibility and Accounts

To use Structure, you must be at least 18 years old and capable of forming a binding contract. By registering, you represent that the information you provide is accurate, that you have the authority to bind any organization on whose behalf you are using the Service, and that your use of the Service complies with all applicable laws.

You are responsible for maintaining the confidentiality of your account credentials and for all activity that occurs under your account. Notify us immediately at support [at] usestructure.com if you suspect unauthorized access.

You may not share your account, transfer it to another person, or create accounts using automated means.

2. Description of the Service

Structure provides tools for property owners, landlords, hosts, and property managers to organize properties, manage projects, store documents and inventory, communicate with guests and collaborators, and access AI-assisted features. The Service may include free and paid tiers, and we may add, remove, or modify features, or change product package grouping of features and/or offerings at any time.

Some features rely on shared access mechanisms — guest portals, professional invitations, and shareable read-only links — which allow third parties to view or contribute information you designate. You are responsible for understanding what each sharing mechanism exposes and to whom.

3. Subscriptions, Fees, Payments and Refunds

Structure offers a free tier and one or more paid subscription tiers. Pricing, included features, and limits for each tier are described on our pricing page and may change from time to time. We will provide reasonable notice of material changes affecting your active subscription.

Paid subscriptions renew automatically at the end of each billing period unless canceled the day before the renewal date. You authorize us to charge your payment method on file for each renewal. Credit card, debit card, EFT and/or processing fees are non-refundable except where required by law or expressly stated by us in writing.

If a payment fails, we may suspend or downgrade your account until the balance is resolved. You remain responsible for any taxes applicable to your subscription.

You can cancel a Subscription at any time with effect from the end of your current billing period. Your cancellation will take effect at the end of your current billing period, and you will not be charged again after that. You can cancel your Subscription through the Support widget, in your logged in account or you can email your cancellation request to support [at] usestructure.com. Refunds will be processed within 10 business days of notice of cancellation.

Note, refunds may take 4-6 weeks to be received based on bank/credit card processors, which is not in our control.

4. Your Content and Responsibilities

"User Content" means any data, files, photos, project details, guest information, messages, inventory records, notes, or other material that you, your collaborators, or your guests submit to the Service.

You retain ownership of your User Content. By submitting User Content, you grant Sigma7 Group Inc a worldwide, non-exclusive, royalty-free license to host, store, reproduce, modify (for technical purposes such as formatting and resizing), display, and transmit that content solely as needed to operate, improve, and provide the Service to you and the people with which you share it.

You are solely responsible for:

• The accuracy, completeness, legality, and quality of all User Content you submit
• Ensuring you have the right to upload any document, photo, or piece of information you provide, including content about properties, guests, contractors, co-owners, or other third parties
• Obtaining any consents required to share guest details, contact information, or other personal data with Structure or with collaborators you invite
• Backing up any User Content that is critical to you — Structure is not a substitute for independent backup
• All decisions you make based on information stored in or generated by the Service, including project schedules, expense records, repair estimates, and AI-generated suggestions

Structure does not verify the accuracy of User Content, and inaccurate or outdated information you store with us is your responsibility to correct.

5. Acceptable Use

You agree not to use Structure to:

• Submit content that is unlawful, defamatory, harassing, fraudulent, infringing, or that violates the privacy or rights of others
• Upload malware, viruses, or any code intended to disrupt or harm the Service
• Attempt to access accounts, data, or systems you are not authorized to access
• Reverse engineer, scrape, or otherwise extract data from the Service except through features we expressly provide
• Use the Service to send unsolicited communications or spam
• Misrepresent your identity, your relationship to a property, or your authority over a guest's information
• Resell, sublicense, or commercially exploit the Service except as expressly permitted
• Interfere with the Service's operation, security, or other users' ability to use it

Our Right to Review and Remove Content

We reserve the right — but are not obligated — to review, monitor, and remove any User Content that we believe, in our sole discretion, violates these Terms, applicable law, or the operational, ethical, or quality standards we set for the platform. We may suspend access to specific content, features, or accounts where we deem it necessary to protect the Service, our users, or third parties.

We will make reasonable efforts to notify you when we remove content you uploaded, except where notification would be impractical, unsafe, or legally restricted.

6. Access to Your Data

To operate, maintain, secure, and improve the Service, we reserve the right to access, review, and process User Content stored in your account. This includes, without limitation:

• Investigating suspected violations of these Terms or applicable law
• Responding to support requests, technical issues, or abuse reports
• Complying with legal process, court orders, or regulatory obligations
• Detecting and preventing fraud, security incidents, or unauthorized use
• Operating, training, and improving Service features, including AI-assisted features, in accordance with our Privacy Policy

Access to your User Content by Structure personnel is limited to authorized employees and contractors with a legitimate operational reason. Our handling of your data is further described in our Privacy Policy.

7. AI-Assisted Features

Structure includes AI-assisted features, including Mason, our in-product AI assistant. These features may generate summaries, suggestions, cost estimates, draft text, search results, and other outputs based on your User Content and on third-party information.

You acknowledge that:

• AI outputs may be incomplete, inaccurate, outdated, or unsuitable for your specific situation
• AI outputs are not professional advice — including legal, financial, tax, real estate, contractor, insurance, or engineering advice — and should not be relied upon as a substitute for consulting a qualified professional
• Cost estimates, project recommendations, and similar outputs are illustrative only and may differ materially from actual prices, timelines, or outcomes
• You are responsible for reviewing AI outputs before acting on them or sharing them with others
• To provide AI features, your User Content may be processed by Sigma7 Group Inc's systems and by third-party AI service providers we engage; details are in our Privacy Policy

We may modify, restrict, or discontinue AI features at any time.

8. Sharing, Collaborators, and Guests

Structure lets you share information with co-owners, professionals, guests, and others through invitations, role assignments, and shareable links. When you share content:

• You are responsible for choosing the right recipients and access level
• Recipients may view, download, or in some cases edit the content you share, depending on the role you grant
• Recipients of shareable links may include anyone who obtains the link; therefore treat link sharing accordingly
• You are responsible for revoking access when it is no longer appropriate
• Information you share with guests through guest portals (such as Wi-Fi codes, door codes, or check-in details) is your responsibility to manage and update

Guests and other invited parties who use Structure are also bound by these Terms with respect to their access.

9. Third-Party Services and Professionals

Structure may integrate with third-party services or display information from third parties (such as price ranges, location data, or content provided by professionals you invite). We do not endorse and are not responsible for third-party services, websites, or contractors you engage through or based on information from the Service.

Any agreement, transaction, or relationship between you and a third party — including any professional you invite to view a project — is solely between you and that third party.

10. Intellectual Property

The Service, including its software, design, branding, "Structure" and "Mason" names, logos, and all related materials, is owned by Sigma7 Group Inc or its licensors and is protected by intellectual property laws. We grant you a limited, non-exclusive, non-transferable, revocable license to use the Service in accordance with these Terms.

You may not copy, modify, distribute, sell, or create derivative works of the Service or any part of it, except as expressly permitted.

11. Feedback

If you provide suggestions, ideas, or feedback about the Service, you grant us a perpetual, irrevocable, royalty-free license to use that feedback for any purpose, without obligation to you.

12. Beta and Early Access Features

Some features may be offered as beta, preview, or early access ("Beta Features"). Beta Features are provided "as is," may be unstable, may change without notice, and are not subject to the same support or service-level expectations as the rest of the Service. We may discontinue Beta Features at any time.

13. Suspension and Termination

You may close your account at any time through your account settings or by contacting us. We may suspend or terminate your access to the Service, with or without notice, if:

• You violate these Terms or applicable law
• Your account poses a security, legal, or operational risk to the Service or others
• Your payment fails and is not resolved within a reasonable period
• We are required to do so by law or legal process
• We discontinue the Service or any portion of it

Upon termination, your right to use the Service ends immediately. We may delete your User Content after a reasonable retention period, as described in our Privacy Policy. Sections of these Terms that by their nature should survive termination — including ownership, disclaimers, limitation of liability, indemnification, and dispute resolution — will survive.

14. Disclaimers

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE," WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, AND ACCURACY. WE DO NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, ERROR-FREE, OR SECURE, OR THAT ANY DATA, AI OUTPUT, OR INFORMATION PROVIDED THROUGH THE SERVICE WILL BE ACCURATE OR RELIABLE.

YOUR USE OF THE SERVICE IS AT YOUR SOLE RISK.

15. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, SIGMA7 GROUP INC AND ITS OFFICERS, DIRECTORS, EMPLOYEES, CONTRACTORS, AND AFFILIATES WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, CONSEQUENTIAL, SPECIAL, PUNITIVE, OR EXEMPLARY DAMAGES, OR FOR ANY LOSS OF PROFITS, REVENUE, DATA, GOODWILL, OR BUSINESS OPPORTUNITIES, ARISING OUT OF OR RELATED TO THESE TERMS OR THE SERVICE, EVEN IF WE HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

OUR TOTAL AGGREGATE LIABILITY FOR ALL CLAIMS ARISING OUT OF OR RELATED TO THESE TERMS OR THE SERVICE WILL NOT EXCEED THE GREATER OF (A) THE AMOUNTS YOU PAID US IN THE TWELVE MONTHS PRECEDING THE EVENT GIVING RISE TO THE CLAIM, OR (B) ONE HUNDRED U.S. DOLLARS ($100).

Some jurisdictions do not allow certain limitations, so portions of this section may not apply to you.

16. Indemnification

You agree to defend, indemnify, and hold harmless Sigma7 Group Inc and its affiliates, officers, directors, employees, and agents from any claims, damages, liabilities, losses, and expenses (including reasonable attorneys' fees) arising out of or related to (a) your User Content, (b) your use of the Service, (c) your violation of these Terms, (d) your violation of any applicable law or third-party right, or (e) information you share with guests, collaborators, or professionals through the Service.

17. Governing Law, Arbitration, and Class Action Waiver

17.1 Governing Law

These Terms are governed by the laws of the Commonwealth of Massachusetts, without regard to its conflict of laws rules. The Federal Arbitration Act ("FAA") governs the interpretation and enforcement of this Section 17.

17.2 Informal Resolution

Before filing any formal claim, you and Sigma7 Group Inc agree to first try to resolve the dispute informally. Send a written notice describing the dispute, the relief sought, and your contact information to support [at] usestructure.com. We will do the same for any claim we have against you. If the dispute is not resolved within sixty (60) days after the notice is received, either party may proceed to arbitration.

17.3 Binding Individual Arbitration

Except for the carve-outs in Section 17.5, you and Sigma7 Group Inc agree that any dispute, claim, or controversy arising out of or relating to these Terms or the Service will be resolved exclusively through final and binding individual arbitration, not in court.

The arbitration will be administered by the American Arbitration Association ("AAA") under its Consumer Arbitration Rules (or, for non-consumer disputes, its Commercial Arbitration Rules), as modified by these Terms. The AAA's rules are available at www.adr.org. The arbitration will be conducted by a single neutral arbitrator.

The seat of arbitration is Boston, Massachusetts. Arbitration may be conducted in person, by phone, by video, or based on written submissions, at the election of the party seeking relief, subject to the arbitrator's discretion. If you are an individual consumer and travel to Boston would be a hardship, the arbitrator may direct that hearings be held remotely or in a location closer to you.

The arbitrator's decision is final and binding, and judgment on the award may be entered in any court of competent jurisdiction.

17.4 Class Action Waiver

You and Sigma7 Group Inc 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 action. The arbitrator may not consolidate claims of more than one person and may not preside over any form of representative or class proceeding. If a court or arbitrator determines that this class action waiver is unenforceable as to a particular claim or remedy, then that claim or remedy (and only that claim or remedy) must be brought in court rather than in arbitration; all other claims will proceed in arbitration.

17.5 Carve-Outs

Notwithstanding the above, either party may:

• Bring an individual action in small claims court for any claim within that court's jurisdiction
• Seek injunctive or other equitable relief in court to protect intellectual property rights, confidential information, or to prevent unauthorized access to the Service
• Pursue enforcement actions, validity determinations, or claims arising from or relating to theft, piracy, or unauthorized use of intellectual property in a court of competent jurisdiction

For any claim not subject to arbitration under this Section, the parties consent to the exclusive jurisdiction of the state and federal courts located in Massachusetts.

17.6 30-Day Right to Opt Out

You may opt out of this arbitration agreement and class action waiver by sending written notice to support [at] usestructure.com within thirty (30) days of first accepting these Terms. Your notice must include your full name, the email associated with your account, and a clear statement that you wish to opt out of arbitration. Opting out will not affect any other part of these Terms. If you opt out, disputes will be resolved in the Massachusetts courts identified in Section 17.5.

17.7 Costs and Fees

The allocation of arbitration filing fees, administrative fees, and arbitrator compensation will be governed by the applicable AAA rules, except that Sigma7 Group Inc will pay any portion of those fees that exceeds what you would have paid to file the same claim in court, where required by AAA rules or applicable law. Each party is otherwise responsible for its own attorneys' fees and costs, except where the arbitrator awards them under applicable law.

17.8 Severability of This Section

If any portion of this Section 17 (other than the class action waiver in Section 17.4) is found unenforceable, that portion will be severed and the remainder will continue in effect. If the class action waiver is found unenforceable, the entirety of Section 17 will be void with respect to the affected claims, and those claims will be resolved in the Massachusetts courts identified in Section 17.5.

17.9 Survival

This Section 17 survives termination of these Terms and your relationship with Sigma7 Group Inc.

18. Changes to These Terms

We may update these Terms from time to time. If we make material changes, we will notify you by email or through the Service before the changes take effect. Your continued use of the Service after the effective date constitutes acceptance of the updated Terms. If you do not agree, you must stop using the Service.

19. General

These Terms, together with our Privacy Policy and any other policies referenced here, constitute the entire agreement between you and Sigma7 Group Inc regarding the Service. If any provision is found unenforceable, the remaining provisions remain in effect. Our failure to enforce any provision is not a waiver of that provision. You may not assign these Terms without our consent; we may assign them freely.
