Terms of Use

Version 2026-09-02 · Effective September 2, 2026

These Terms of Use ("Terms") govern your access to and use of TerraCalc.app ("TerraCalc"), which is operated by Livio Technologies ("Livio Technologies," "we," "us," or "our").

By accessing or using TerraCalc, including calculators available without an account, you agree to these Terms. If you create an account, you may also be required to affirmatively indicate your acceptance of these Terms through the account-creation interface.

If you access or use TerraCalc on behalf of a company, employer, or other organization, you represent that you have authority to bind that organization to these Terms, and "you" includes that organization where applicable.

If you do not agree to these Terms, do not access or use TerraCalc.

1. Planning Estimates and Professional Responsibility

TerraCalc provides calculators, estimates, and related information for general planning and informational purposes only.

TerraCalc does not provide engineering, architectural, surveying, construction, structural, geotechnical, safety, code-compliance, permitting, purchasing, financial, or other professional advice.

Construction calculators, including concrete, rebar, wire mesh, and similar calculators, estimate material quantities based on information and assumptions you provide. They do not determine structural design requirements, required reinforcement, load capacity, slab or footing design, reinforcement spacing, lap or development lengths, code compliance, or whether a particular construction method is appropriate for a project.

TerraCalc calculations and estimates may depend on information supplied by you, material assumptions, product specifications, package sizes, site conditions, waste factors, rounding, regional practices, supplier information, and other factors that may vary or be inaccurate.

TerraCalc does not guarantee that any calculation, estimate, quantity, measurement, material recommendation, cost estimate, or other result is accurate, complete, current, or suitable for your particular project or intended use.

TerraCalc does not inspect project sites or independently verify measurements, site conditions, materials, product information, or other information supplied by users or third parties.

You are solely responsible for independently verifying measurements, assumptions, quantities, material requirements, structural requirements, site conditions, applicable laws and codes, permitting requirements, product specifications, supplier information, prices, and costs before purchasing materials, beginning construction, or relying on any TerraCalc result.

For projects involving structural, safety, regulatory, engineering, architectural, surveying, or other professional requirements, you should consult an appropriately qualified and licensed professional.

Do not rely on TerraCalc as the sole basis for a construction, purchasing, structural, safety, or other material decision.

2. Accounts

Some TerraCalc features require an account.

You are responsible for maintaining the security of the email account and authentication methods associated with your TerraCalc account and for activity occurring through your account, except to the extent caused by Livio Technologies' violation of its legal obligations.

You are responsible for providing accurate information when creating an account and for keeping account information reasonably current.

You must not share account credentials in a manner that compromises account security or use another person's account without authorization.

You should promptly notify us if you believe your account has been compromised.

3. Projects and User Data

You retain your rights in project information and other content that you submit to TerraCalc ("User Data").

You grant Livio Technologies and its service providers a limited, non-exclusive, worldwide license to host, store, reproduce, transmit, process, display, and otherwise use User Data solely as reasonably necessary to provide, maintain, secure, troubleshoot, support, and improve the TerraCalc features you request and to comply with applicable law.

This license continues for as long as reasonably necessary to provide the applicable service and thereafter only to the extent reasonably necessary to complete deletion, maintain security, comply with legal obligations, resolve disputes, prevent fraud or abuse, or maintain backup and disaster-recovery systems.

When User Data is deleted in accordance with our deletion practices, Livio Technologies will no longer use that User Data for ordinary operation of TerraCalc, except as permitted or required by applicable law or as described in our Privacy Notice.

Livio Technologies may create and use information that has been aggregated or de-identified so that it does not reasonably identify you, your account, or your projects.

We may use aggregated or de-identified information to operate, analyze, secure, test, develop, and improve TerraCalc, including its calculators, calculation logic, material information, features, performance, reliability, and user experience.

We will not intentionally publish your project names, contact information, or identifiable individual project records as public examples without your permission.

Nothing in these Terms transfers ownership of your User Data to Livio Technologies.

You are responsible for maintaining independent copies of important project information. TerraCalc is not a substitute for your own records or backups.

4. Acceptable Use

You may not:

We may investigate suspected violations and may suspend or restrict access when reasonably necessary to protect TerraCalc, our users, our systems, or the public.

5. Service Availability and Changes

TerraCalc is evolving software. We may correct errors, modify features, change calculation assumptions, update material catalogs, impose reasonable usage limits, suspend features, or discontinue portions of the service.

Material catalogs, supplier information, calculation assumptions, and other information may change over time.

Saved estimates may retain version information where available, but we do not guarantee that historical calculations will remain reproducible indefinitely.

Cloud-project availability is provided on a reasonable-efforts basis. We do not guarantee uninterrupted availability, error-free operation, or permanent preservation of cloud projects.

We may modify, suspend, or discontinue the service or particular features at any time, subject to applicable law.

6. Account Suspension and Termination

You may stop using TerraCalc or delete your account at any time using available account controls.

We may suspend or terminate an account or access to TerraCalc if:

Where reasonably practicable, we will provide notice before suspension or termination. We may act without prior notice when reasonably necessary to protect the service, users, or public.

Account termination does not eliminate obligations or rights that by their nature should survive termination. Following account termination, access to User Data may cease and User Data may be deleted in accordance with our deletion and retention practices, subject to applicable law.

7. Intellectual Property

TerraCalc, including its software, interface, design, branding, text, graphics, calculation logic, databases, and other original content, is owned by or licensed to Livio Technologies and is protected by applicable intellectual-property laws.

Except as expressly permitted by these Terms or applicable law, you may not copy, reproduce, modify, distribute, sell, lease, reverse engineer, or create derivative works from TerraCalc or its proprietary components.

Your use of TerraCalc does not grant you ownership of TerraCalc or its underlying technology.

8. Third-Party Services

TerraCalc may rely on third-party services for hosting, authentication, database storage, email, analytics, advertising, security, site delivery, and other infrastructure.

Third-party services may be subject to their own terms and privacy policies.

Livio Technologies is not responsible for the independent acts, omissions, availability, security, or policies of third-party services that are outside Livio Technologies' reasonable control.

9. Security

Livio Technologies uses reasonable administrative, technical, and organizational safeguards designed to protect TerraCalc and information processed through the service.

These measures may include access controls, encrypted transport, monitoring, and other technical and organizational safeguards appropriate to the nature of the service and information processed.

However, no internet service, transmission, authentication method, storage system, database, or security control can guarantee complete security.

You are responsible for maintaining reasonable security of your account, email account, authentication methods, and devices.

If Livio Technologies becomes aware of a security incident affecting personal information, we will take reasonable steps to investigate, contain, remediate, and provide notifications required by applicable law.

Nothing in these Terms limits any liability or obligation that cannot legally be limited or excluded.

10. Disclaimers

TO THE MAXIMUM EXTENT PERMITTED BY LAW, TERRACALC AND ALL SERVICES, CALCULATIONS, ESTIMATES, CONTENT, MATERIAL INFORMATION, AND FEATURES ARE PROVIDED "AS IS" AND "AS AVAILABLE."

LIVIO TECHNOLOGIES DISCLAIMS ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING WARRANTIES OF ACCURACY, MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, NON-INFRINGEMENT, AVAILABILITY, RELIABILITY, AND THAT THE SERVICE WILL BE ERROR-FREE OR UNINTERRUPTED.

WE DO NOT WARRANT THAT CALCULATIONS, ESTIMATES, MATERIAL INFORMATION, PRODUCT INFORMATION, OR OTHER CONTENT WILL BE ACCURATE, COMPLETE, CURRENT, OR SUITABLE FOR YOUR PARTICULAR PROJECT.

YOU ASSUME RESPONSIBILITY FOR VERIFYING INFORMATION BEFORE RELYING ON IT.

No oral or written information or advice provided by Livio Technologies or through TerraCalc creates a warranty unless expressly stated in these Terms.

Nothing in these Terms excludes or limits a warranty or right that cannot legally be excluded or limited.

11. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, LIVIO TECHNOLOGIES AND ITS OWNERS, OFFICERS, DIRECTORS, EMPLOYEES, CONTRACTORS, AFFILIATES, LICENSORS, AND SERVICE PROVIDERS WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, EXEMPLARY, CONSEQUENTIAL, PUNITIVE, OR SIMILAR DAMAGES, OR FOR LOSS OF PROFITS, REVENUE, BUSINESS, DATA, GOODWILL, OR OPPORTUNITY, ARISING OUT OF OR RELATING TO:

TO THE MAXIMUM EXTENT PERMITTED BY LAW, THE TOTAL AGGREGATE LIABILITY OF LIVIO TECHNOLOGIES AND ITS OWNERS, OFFICERS, DIRECTORS, EMPLOYEES, CONTRACTORS, AFFILIATES, LICENSORS, AND SERVICE PROVIDERS ARISING OUT OF OR RELATING TO TERRACALC OR THESE TERMS WILL NOT EXCEED THE GREATER OF (A) THE AMOUNT YOU PAID TO LIVIO TECHNOLOGIES FOR TERRACALC DURING THE TWELVE MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM OR (B) ONE HUNDRED U.S. DOLLARS ($100).

These limitations apply regardless of the legal theory on which a claim is based and even if Livio Technologies has been advised of the possibility of the damages.

Nothing in these Terms limits liability that cannot legally be limited or excluded.

12. Indemnification

To the maximum extent permitted by law, you agree to defend, indemnify, and hold harmless Livio Technologies and its owners, officers, directors, employees, contractors, affiliates, licensors, and service providers from and against third-party claims, liabilities, damages, losses, and reasonable expenses arising from:

This provision does not require you to indemnify Livio Technologies for Livio Technologies' own negligence, willful misconduct, or other liability to the extent such indemnification is prohibited by applicable law.

13. Governing Law and Venue

To the maximum extent permitted by applicable law, these Terms and any dispute arising out of or relating to TerraCalc or these Terms will be governed by the laws of the State of North Carolina, without regard to its conflict-of-law principles.

To the maximum extent permitted by applicable law, any action or proceeding arising out of or relating to these Terms or TerraCalc will be brought in the state or federal courts located in the North Carolina county in which Livio Technologies maintains its principal place of business, and you consent to the personal jurisdiction and venue of those courts.

Nothing in this section limits rights or remedies that applicable law requires to remain available to consumers or other protected persons.

14. Informal Dispute Resolution

Before filing a formal legal action, you and Livio Technologies agree to make a good-faith effort to resolve the dispute informally. A party seeking to raise a dispute should provide the other party with written notice describing the nature of the dispute and the requested resolution. Notices to Livio Technologies should be sent to hello@terracalc.app.

The parties will have 30 days after receipt of the notice to attempt to resolve the dispute informally, unless they mutually agree in writing to extend that period. If the dispute has not been resolved within that period, either party may pursue any remedies otherwise available under these Terms or applicable law.

This informal resolution requirement does not prevent either party from seeking emergency, temporary, preliminary, or other injunctive or equitable relief when reasonably necessary to protect intellectual property, confidential information, security, or other legally protectable interests, or from taking action reasonably necessary to preserve a claim or comply with an applicable statute of limitations or other filing deadline.

15. Entire Agreement

These Terms and any supplemental terms expressly incorporated into them constitute the entire agreement between you and Livio Technologies concerning your use of TerraCalc and supersede prior or contemporaneous agreements, understandings, or representations concerning that subject. Our Privacy Notice describes how Livio Technologies collects, uses, and protects personal information.

16. Severability

If any provision of these Terms is determined to be unlawful, invalid, or unenforceable, that provision will be enforced to the maximum extent permitted by law, and the remaining provisions will remain in full force and effect.

17. Waiver

A failure by Livio Technologies to enforce any provision of these Terms does not constitute a waiver of its right to enforce that provision later.

A waiver must be express and applies only to the specific instance for which it is given.

18. Assignment

You may not assign or transfer your rights or obligations under these Terms without Livio Technologies' prior written consent.

Livio Technologies may assign these Terms, in whole or in part, in connection with a merger, acquisition, corporate reorganization, sale of assets, financing, or similar transaction.

19. Force Majeure

Livio Technologies will not be responsible for delay or failure to perform caused by events outside its reasonable control, including natural disasters, failures of telecommunications or hosting infrastructure, internet outages, power failures, cyberattacks, labor disputes, governmental actions, war, civil unrest, or other events beyond its reasonable control.

20. Changes to These Terms

We may update these Terms as TerraCalc, our business, or applicable legal requirements change.

We will identify changes by publishing a new version and effective date.

For material changes to these Terms, we may require you to affirmatively accept the updated Terms before you continue using account-based features. Notice may be provided through the service, by email, or through another reasonable method.

If affirmative acceptance is required and you do not accept the updated Terms, you may stop using TerraCalc and may use available account controls to export or delete your account information, subject to applicable law and our retention obligations.

For non-material changes, continued use of TerraCalc after the effective date may constitute acceptance to the extent permitted by applicable law.

We may retain a record of the version of the Terms you accepted and the date and method of acceptance.

21. Electronic Acceptance

When you create a TerraCalc account, you may be required to affirmatively indicate your agreement to these Terms through the TerraCalc account-creation interface.

Electronic acceptance, including selecting an acceptance checkbox and submitting the account-creation form, constitutes your electronic signature and agreement to these Terms to the extent permitted by applicable law.

You may be required to accept updated Terms before continuing to use certain account-based features when we determine that affirmative acceptance is appropriate.

22. Survival

Provisions that by their nature should survive termination will survive, including provisions concerning User Data, intellectual property, disclaimers, limitations of liability, indemnification, governing law, dispute resolution, and other provisions intended to survive termination.
