DRAFTHALO Sheets End User License Agreement

Version 2.0
Effective November 1, 2026

IMPORTANT - SOFTWARE LICENSE AND PROJECT-FILE RESPONSIBILITY

This EULA governs installation and use of DRAFTHALO Sheets, a sheet-management productivity tool. When directed by you, it can change sheet numbers, sheet titles, properties, and supported sheet set or layout information. Maintain backups and review the affected information before using or issuing project documents.

This End User License Agreement ("EULA") is a legal agreement between the Customer defined below and DRAFTHALO LLC ("DRAFTHALO," "we," "us," or "our") for DRAFTHALO Sheets and related software, updates, documentation, and license credentials (collectively, the "Software").

By affirmatively accepting this EULA through an acceptance process that presents it to you, you agree to be bound by it. If you accept this EULA for a company or other organization, you represent that you are authorized to accept it on that Customer's behalf. The Customer exercises its license through Authorized Users, whose use is subject to this EULA. If you do not agree, do not install, activate, or use the Software.

This EULA governs installation, software use, user-seat and Device rights, project-file operations, and software-specific warranties. The Terms of Service govern website services, purchases, billing administration and support. Section 15 and Terms Section 16 contain the same combined liability allocation; neither creates an additional cap. Section 18 allocates the remaining subjects among the documents.

1. Definitions

For purposes of this EULA:

"Customer" means the individual or organization that purchases the applicable subscription or receives an authorized trial entitlement.

"Authorized User" means the individual person assigned by the Customer to use a purchased DRAFTHALO Sheets Seat or an authorized trial entitlement.

"Seat" means a purchased right for one assigned Authorized User to use the Software, subject to the user and Device limits in Section 3. A Seat is not a Device; authorized trial entitlements are addressed separately.

"Device" means a computer or supported computing environment on which the Software is installed or activated.

"Documentation" means DRAFTHALO-provided user guides, installation instructions, release notes, support materials, and other product documentation.

"Subscription Term" means the paid period during which the applicable license entitlement is active.

"Host Software" means the supported Autodesk software environment with which DRAFTHALO Sheets is designed to operate.

"Order" means the transaction-specific checkout or order record identifying the product, purchased quantity, subscription term, price, and expressly disclosed offer for that transaction. Its effect is subject to the document allocation in Section 18.

2. License Grant

Subject to payment of applicable fees, an active license entitlement, and continued compliance with this EULA, DRAFTHALO grants the Customer a limited, non-exclusive, non-sublicensable license to install and use the Software for internal professional or business purposes during the applicable Subscription Term, exercised through its Authorized Users within the purchased Seat limits. The license is subject to suspension or termination only as provided in Section 16 or applicable law.

Where DRAFTHALO provides a 30-day trial entitlement, the limited license above also permits use by the Customer through its Authorized User during the authorized trial period, subject to this EULA and the applicable trial terms rather than a requirement to purchase a Seat. A trial does not create a perpetual license or determine the terms of any later paid subscription.

The Software is licensed, not sold. No ownership interest in the Software or DRAFTHALO intellectual property is transferred to you.

3. Authorized User, Device Activation, and Transfers

Unless DRAFTHALO expressly states otherwise for a particular plan, each purchased Seat is assigned to one Authorized User and may be active on one Device at a time. A team subscription may use one license key with an adjustable number of purchased Seats; the shared team key does not remove the per-user or one-active-Device-per-Seat limits.

A team license key is an administrative credential for the purchased Seats; it is not an additional Seat and does not authorize unrestricted or concurrent sharing beyond those Seats. Device activation counts do not replace the per-user license restrictions.

The Authorized User may move the license to another Device using DRAFTHALO-supported deactivation, reactivation, or license-transfer procedures. The Customer may reassign a Seat from one employee or individual user to another when reasonably necessary for personnel changes or license administration, provided the Seat is not shared concurrently and the reassignment does not exceed the number of Seats purchased.

System administrators or other personnel authorized by the Customer may assist with installation, deployment, activation, deactivation, or license administration for its purchased Seats or authorized trial entitlement, but administrative access does not create additional user rights. Assistance with installation or license administration does not, by itself, authorize a person to change billing arrangements, accept new contractual commitments for the Customer, or access or disclose project content. Those actions require the Customer's authorization and any necessary permission from the applicable content owner.

Use through virtual machines, remote desktops, cloud-hosted desktops, shared workstations, or similar environments is permitted only where technically supported by DRAFTHALO and where the use remains consistent with the Authorized User and activation limits of the purchased license.

4. Subscription Validation and Offline Use

The Software may periodically communicate with Lemon Squeezy, DRAFTHALO's licensing provider, or DRAFTHALO to activate the Software and validate license, subscription, and activation status.

The current product design generally uses a 24-hour validation cache and, after successful online validation, may permit eligible offline use for up to 14 days. Eligibility and duration remain subject to the license status and subscription or license expiry. The cache and offline grace period do not extend an expired, revoked, or otherwise ineligible entitlement and are not a guarantee of uninterrupted offline access in every circumstance.

After the applicable offline period, licensed functionality may require successful online validation before continued use. Validation may also be required after significant licensing, account, subscription, security, Device, or Software changes.

The Software keeps local license and EULA-acceptance records in Windows-protected storage. The accepted EULA version and date are recorded separately from activation; activation alone is not a substitute for the applicable acceptance process.

DRAFTHALO may reasonably modify licensing and validation mechanisms to address security, fraud, service-provider, technical, or product changes, subject to Section 18. Such a change will not intentionally deprive a valid Customer of material rights purchased for the current paid Subscription Term except where suspension or termination is permitted under Section 16 or applicable law.

5. Permitted Use and Restrictions

Except to the extent applicable law expressly permits otherwise, you may not:

copy, distribute, republish, resell, rent, lease, sublicense, lend, or share the Software or license credentials except as expressly permitted by DRAFTHALO;

use one purchased license concurrently for multiple Authorized Users or Devices in excess of the rights purchased;

circumvent, defeat, interfere with, or attempt to bypass license validation, activation limits, technical protection measures, access controls, or security features;

reverse engineer, decompile, disassemble, or otherwise attempt to derive source code, non-public algorithms, or proprietary implementation details except where applicable law expressly permits that activity notwithstanding this restriction;

modify, adapt, or create derivative works of the Software except as expressly authorized by DRAFTHALO or applicable law;

remove, obscure, or alter proprietary, copyright, trademark, licensing, or attribution notices;

use DRAFTHALO code, documentation, interface assets, or proprietary implementation details through unauthorized copying to create or distribute a competing product; or

use the Software in violation of applicable law or in a manner intended to facilitate fraud, unauthorized access, or unlawful activity.

These restrictions do not prohibit copies reasonably necessary for installation and use expressly authorized by this EULA, or any backup, observation, study, testing, interoperability, or other activity to the extent applicable law does not permit that activity to be restricted by contract. Any applicable third-party license governs the relevant third-party component to the extent required by that license. No additional concurrent user or Device rights are created.

6. Ownership and Intellectual Property

DRAFTHALO and its licensors retain all right, title, and interest in and to the Software, Documentation, DRAFTHALO branding, and related intellectual property, including all copyrights, trademarks, trade secrets, and other proprietary rights, except for third-party components governed by their own licenses.

The Customer and any applicable third-party owners retain their rights in project files and project content. A license key, Seat assignment, or administrative role does not transfer ownership of that content to DRAFTHALO or to an administrator.

If you voluntarily provide product suggestions or feature ideas, DRAFTHALO may use those suggestions or ideas for product development and business purposes without compensation. This permission does not apply to project files, confidential information, personal information, or other customer or third-party content included with a submission; those materials remain subject to the applicable support permissions, any applicable confidentiality commitments, and Privacy Policy. No ownership in those materials is transferred.

7. Updates and Supported Host Software

An active subscription may include updates, bug fixes, compatibility changes, security changes, and feature changes that DRAFTHALO releases generally to customers during the Subscription Term. DRAFTHALO does not promise that every requested feature, fix, or compatibility change will be released.

Supported Autodesk® AutoCAD® and Civil 3D® software versions are identified in the DRAFTHALO release documentation applicable to the Customer's purchase. DRAFTHALO may add or change support for Host Software versions, operating systems, dependencies, or configurations for future purchases and terms, subject to the protections below.

DRAFTHALO will not withdraw support for the Customer's purchased supported configuration during an already-paid Subscription Term where reasonably practicable. If withdrawal during that term is unavoidable and materially prevents licensed use, we will provide a reasonable supported alternative or permit termination of the affected Seats with a pro-rata refund of their unused paid term. This does not promise indefinite support or compatibility with a future Host Software version. Changes remain subject to Section 18.

Autodesk software and other third-party software are licensed separately and are not included with DRAFTHALO Sheets. You are responsible for maintaining valid third-party licenses and supported system configurations required to use the Software.

8. Sheet Information and Verification

The Software manages sheet information. When you direct it to do so, supported operations can read or modify sheet set metadata, sheet numbers, sheet titles, custom properties, sheet set layout references, and physical layout tab names in the associated DST or DWG files. Local logs, recovery backups, and operation history may record these operations. The Software does not perform engineering design calculations or independently validate design content.

You are responsible for determining whether a proposed sheet-management operation is appropriate and for reviewing the preview, warnings, and resulting changes.

You are responsible for maintaining normal project backups, file-history, version-control, document-control, and recovery procedures appropriate to your organization and project. DRAFTHALO Sheets is not a substitute for those procedures.

Before using or issuing affected project documents, verify the sheet numbers, titles, properties, layout names, references, and other information changed by the operation under your normal document-control and quality-control procedures.

DRAFTHALO Sheets may include safeguards such as previews, validation checks, recovery backups, refusal conditions, diagnostics, and DHUNDO-oriented operation history. These safeguards are intended to reduce risk but do not guarantee prevention or recovery of every user error, software error, file conflict, data loss, corruption event, network problem, third-party interaction, or unsupported project condition.

9. Professional Responsibility

DRAFTHALO Sheets is a sheet-management productivity tool. It does not provide engineering or other professional design judgment and does not approve or certify project documents.

You and your organization remain responsible for the accuracy, completeness, suitability, coordination, and professional review of project documents and deliverables, and for compliance with applicable laws, regulations, standards, contracts, licensing requirements, client requirements, and professional obligations.

Nothing in the Software or Documentation should be interpreted as replacing the judgment of a qualified professional or your organization's required quality-assurance and quality-control processes.

10. Customer Project Content and Support Materials

Normal use of the Software is designed so that core CAD and Sheet Set operations occur locally on your Device and do not require uploading your project drawings or Sheet Set content to DRAFTHALO.

If you voluntarily provide project files, screenshots, logs, diagnostics, or other materials to DRAFTHALO for support, you represent that you are authorized to provide those materials. You should provide only information reasonably necessary to investigate the issue and should remove or redact sensitive information that is not needed for support. Diagnostics and logs may contain project names and local or network file paths.

Providing support materials does not transfer ownership of your project files or project content to DRAFTHALO. DRAFTHALO's handling of personal information associated with support is described in the DRAFTHALO Privacy Policy.

The reasonable-care confidentiality and support-material retention duties in Section 8 of the Terms of Service apply to nonpublic materials supplied for DRAFTHALO Sheets support. Those duties survive expiration or termination as provided there. The permission to submit support materials does not authorize unrelated use of confidential information.

11. Third-Party Software and Services

The Software is designed for use with certain third-party products and services, including Autodesk Host Software and licensing or commerce infrastructure provided by third parties such as Lemon Squeezy.

Third-party products and services are governed by their own terms, licenses, availability, system requirements, security practices, and policies. DRAFTHALO does not control third-party products and does not guarantee their uninterrupted availability, continued compatibility, or continued support.

Changes made by a third party to its software, APIs, licensing systems, operating requirements, security controls, or services may affect DRAFTHALO Sheets. DRAFTHALO may make commercially reasonable efforts to adapt supported versions, but does not guarantee compatibility with every third-party change or configuration.

The third-party limitations in this section do not eliminate the supported-configuration protections in Section 7, the covered-unusability remedy in Section 16, or the midterm-change protections in Section 18.

12. International Use and Local Requirements

The Software is developed and distributed by a United States company and is currently provided in English. DRAFTHALO documentation and product support are also currently provided primarily in English.

You are responsible for determining whether installation and use of the Software are permitted and appropriate in your jurisdiction, organization, and professional environment.

DRAFTHALO does not warrant that the Software satisfies jurisdiction-specific engineering, surveying, document-control, professional-practice, procurement, accessibility, cybersecurity, localization, or other regulatory requirements. You remain responsible for compliance with laws, regulations, standards, contracts, and professional obligations applicable to your work.

Nothing in this EULA excludes or limits rights or remedies that applicable law does not permit the parties to exclude or limit.

13. Export and Sanctions Compliance

You may not use, export, re-export, transfer, release, or make the Software or related technical information available in violation of applicable United States export-control, sanctions, or trade laws, or other applicable trade restrictions. You are responsible for compliance with trade restrictions applicable to you and your organization.

Each party remains responsible for export-control and sanctions obligations applicable to its own activities. Nothing in this section transfers DRAFTHALO's legal compliance duties to the Customer or authorizes a prohibited transaction.

14. Warranty Disclaimer

EXCEPT FOR EXPRESS COMMITMENTS IN THIS EULA OR THE APPLICABLE ORDER AND RIGHTS THAT CANNOT LAWFULLY BE EXCLUDED, THE SOFTWARE AND DOCUMENTATION ARE PROVIDED "AS IS" AND "AS AVAILABLE." TO THE MAXIMUM EXTENT PERMITTED BY LAW, DRAFTHALO DISCLAIMS IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT.

DRAFTHALO DOES NOT WARRANT THAT THE SOFTWARE WILL BE ERROR-FREE, UNINTERRUPTED, SECURE, OR COMPATIBLE WITH EVERY DRAWING, SHEET SET, NETWORK ENVIRONMENT, CUSTOMIZATION, THIRD-PARTY PLUGIN, HOST-SOFTWARE VERSION, OPERATING SYSTEM, OR DEVICE CONFIGURATION, OR THAT EVERY ERROR OR FILE CONDITION CAN BE DETECTED, PREVENTED, UNDONE, OR RECOVERED.

GENERAL SUPPORT INFORMATION DOES NOT, BY ITSELF, CREATE AN ADDITIONAL CONTRACTUAL WARRANTY. THIS SECTION DOES NOT NEGATE AN EXPRESS PRODUCT COMMITMENT OR REPRESENTATION THAT APPLICABLE LAW MAKES BINDING, OR ANY NONWAIVABLE WARRANTY OR REMEDY.

Some jurisdictions provide warranties, guarantees, and remedies that cannot lawfully be excluded or restricted. Those rights remain available, and the disclaimers in this section apply only to the extent permitted by applicable law.

15. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, DRAFTHALO WILL NOT BE LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, EXEMPLARY, PUNITIVE, OR CONSEQUENTIAL DAMAGES ARISING OUT OF OR RELATING TO DRAFTHALO SHEETS OR RELATED WEBSITES AND SERVICES. LOST PROFITS, LOST REVENUE, BUSINESS INTERRUPTION, LOSS OF GOODWILL, LOST OR CORRUPTED DATA, PROJECT DELAY, SUBSTITUTE PRODUCTS OR SERVICES, AND DATA OR DOCUMENT RESTORATION, CORRECTION, OR REWORK COSTS ARE EXCLUDED ONLY TO THE EXTENT THEY ARE INDIRECT, INCIDENTAL, SPECIAL, OR CONSEQUENTIAL DAMAGES. OTHERWISE RECOVERABLE DIRECT LOSSES ARE NOT EXCLUDED SOLELY BECAUSE THEY FALL WITHIN ONE OF THOSE CATEGORIES; THEY REMAIN SUBJECT TO THE AGGREGATE CAP BELOW.

TO THE MAXIMUM EXTENT PERMITTED BY LAW, DRAFTHALO'S TOTAL AGGREGATE LIABILITY FOR ALL CLAIMS ARISING FROM THE SAME OR RELATED EVENTS UNDER THE TERMS OF SERVICE AND THE DRAFTHALO SHEETS EULA TOGETHER WILL NOT EXCEED THE GREATER OF (A) THE AMOUNTS THE CUSTOMER PAID FOR THE AFFECTED DRAFTHALO SHEETS SUBSCRIPTION, INCLUDING ALL SEATS UNDER THAT SUBSCRIPTION, DURING THE 12 MONTHS BEFORE THE FIRST EVENT GIVING RISE TO THOSE CLAIMS OR (B) $100. THIS IS ONE COMBINED CAP, NOT A SEPARATE CAP FOR EACH SEAT, DOCUMENT, CLAIM, OR LEGAL THEORY. RECOVERY UNDER ONE DOCUMENT COUNTS TOWARD THE SAME CAP UNDER THE OTHER; THERE IS NO DOUBLE RECOVERY FOR THE SAME LOSS.

THE LIMITATIONS IN THIS SECTION APPLY COLLECTIVELY TO ALL CLAIMS AND ALL THEORIES OF LIABILITY, INCLUDING CONTRACT, WARRANTY, TORT (INCLUDING NEGLIGENCE), STRICT LIABILITY, MISREPRESENTATION, STATUTE, OR OTHERWISE, EVEN IF DRAFTHALO WAS ADVISED THAT DAMAGES WERE POSSIBLE.

Nothing in this agreement excludes or limits liability for DRAFTHALO's fraud or willful injury, or liability for a willful or negligent violation of law to the extent such exclusion or limitation is prohibited. Nothing excludes or limits any other liability or remedy that applicable law does not permit to be excluded or limited. The warranty disclaimers, exclusions of categories of damages, and aggregate liability cap apply only to the extent permitted by law.

This combined liability allocation also applies to the support confidentiality commitment, subject to the nonwaivable exceptions above. It does not reduce an express refund obligation under this EULA, the Terms of Service, or the Refund Policy, or a mandatory legal remedy.

16. Suspension and Termination

This EULA remains effective while your applicable license entitlement is valid unless terminated earlier in accordance with this section.

Ordinary cancellation of future subscription renewal does not itself revoke the current paid entitlement or change the existing license key. Subject to the Terms of Service, Refund Policy, this EULA, and applicable law, licensed access continues through the current paid term and then expires. Refunds, revocation, and suspension or termination for the reasons below are separate from ordinary cancellation.

Trial cancellation and access are governed by the trial offer presented to you; the paid-term continuation described here does not determine trial access.

DRAFTHALO may terminate access for a material breach, subject to the following protections. Before permanently terminating access for an ordinary curable material breach, DRAFTHALO will give the Customer written notice describing the breach and at least 14 calendar days after that notice to correct it. Notice may be sent to the purchase or account email address. DRAFTHALO may immediately suspend only the access reasonably necessary to address fraud, an active security threat, intentional circumvention, unlawful activity, or ongoing material harm. We will restore eligible access when the reason for suspension is resolved. An inherently noncurable material breach does not require a futile cure period. This process does not extend a trial, an expired Subscription Term, or an entitlement for which the required payment has not been made; expiration or temporary loss of access for nonpayment is distinct from permanent termination for breach. Applicable law may require additional notice or protection.

If a failure of DRAFTHALO Sheets or the licensing services required to use it materially prevents use of licensed functionality on a configuration supported for the Customer's current paid Subscription Term, contact support@drafthalo.com with information reasonably necessary to identify the failure. If the verified inability to use that functionality continues for 14 consecutive calendar days after that report and no reasonable workaround restores material functionality, the Customer may terminate the affected Seats and receive a pro-rata refund of their unused paid Subscription Term. Later verification does not restart the 14-day period. The refund is calculated from the amounts paid for the affected Seats and the unused days remaining in that paid term when the Customer requests termination under this provision. The remedy does not apply to an expired or unpaid entitlement, unsupported configurations or modifications, misuse, missing third-party licenses, or a problem confined to the Customer's Device, local network, or internet connection. Time during which eligible offline access or a reasonable workaround permits material use is not time of inability to use. This is a defined termination-and-refund remedy, not an uptime percentage, service-level agreement, or guaranteed response or resolution time. It is additional to the initial-purchase and accidental-renewal refund offers and does not limit mandatory legal remedies.

Expiration or termination ends your right to use licensed functionality. Termination does not require DRAFTHALO to delete or alter your project files and does not transfer ownership of customer project content to DRAFTHALO.

Sections concerning ownership, restrictions that by their nature survive, project responsibility, disclaimers, limitations of liability, governing law and venue, and other provisions that by their nature should survive will survive expiration or termination.

17. Governing Law and Venue

This EULA is governed by the laws of the State of Montana, without regard to conflict-of-law principles, except to the extent applicable nonwaivable law requires otherwise.

To the maximum extent permitted by applicable law, any lawsuit or court proceeding arising out of or relating to this EULA or the Software that is not required to be brought elsewhere shall be brought in a state or federal court of competent jurisdiction located in Montana, and you and DRAFTHALO consent to the personal jurisdiction of those courts.

If you are a consumer, this choice of law and forum does not deprive you of mandatory protections or access to courts that the law applicable to your transaction gives you and does not permit you to waive.

This EULA does not require mandatory arbitration. Nothing in this section prevents either party from seeking appropriate injunctive or equitable relief where available, including relief relating to misuse of intellectual property, unauthorized distribution, or circumvention of licensing controls.

18. General Terms

Entire Agreement and Order of Priority

This EULA, together with applicable purchase terms, the DRAFTHALO Terms of Service, and any policies or checkout terms expressly incorporated into the applicable transaction, governs the subjects they address as allocated below.

The EULA governs installation, software use, user-seat and Device rights, project-file operations, and software-specific warranties. The Terms of Service govern website services, purchases, billing administration and support. The same combined liability allocation in Terms Section 16 and EULA Section 15 applies across both documents, including support confidentiality. The Refund Policy governs the voluntary refund offers and describes additional express refund remedies. Transaction-specific checkout terms in the Order govern the price, quantity, billing interval and expressly disclosed offer for that transaction. The Privacy Policy describes personal-information handling and does not expand software-use rights. These documents do not override nonwaivable law or independent merchant-of-record obligations.

The Privacy Policy is a notice of information practices. Acceptance of the contractual terms does not by itself constitute consent to processing for which applicable law requires separate consent.

If provisions conflict on the same subject, the document assigned that subject above controls. Transaction-specific checkout terms control only the price, quantity, billing interval and expressly disclosed offer for that transaction; they do not, merely by appearing in an Order, amend unrelated software-license restrictions, warranties, or liability provisions.

Severability

If a provision is held unenforceable, the remaining provisions remain in effect to the maximum extent permitted by law, and the unenforceable provision will be interpreted or limited as necessary to make it enforceable where permitted.

No Waiver

A failure or delay by DRAFTHALO to enforce a provision does not waive the right to enforce it later.

Assignment

You may not assign or transfer this EULA or license rights except as expressly permitted by DRAFTHALO, the applicable plan, or Section 3. DRAFTHALO may assign this EULA in connection with a merger, reorganization, financing, sale of assets, or similar business transaction, subject to applicable law.

Changes to This EULA

Materially adverse changes to the commercial terms or material license rights of an already-paid Subscription Term will apply at renewal, not during that paid term. DRAFTHALO will give at least 30 days' advance notice before such a change takes effect and will obtain any consent and provide any additional notice, cancellation, or refund right required by applicable law. If a law requires notice within a particular timing window, we will provide a notice within that window; earlier notice alone does not replace it. During a paid term, DRAFTHALO may make only those materially adverse changes reasonably necessary to comply with law or address a material security risk, with as much advance notice as reasonably practicable. If such a midterm change materially prevents the Customer from using licensed functionality on its supported configuration and no reasonable alternative restores that functionality, the Customer may terminate the affected Seats and receive a pro-rata refund of their unused paid term. Routine fixes and changes that do not materially reduce purchased rights do not require a new agreement, except where applicable law requires it. No change retroactively alters accrued rights or obligations.
