Terms of Service

These Terms are a contract between you and DrawStack, Inc. ("DrawStack", "we") covering drawstack.ai, the DrawStack application and our public tools. By creating an account or using the service you accept them. If you do not accept them, do not use the service.

If you are agreeing on behalf of a company, you confirm you are authorised to bind it, and "you" means that company. Our Privacy Policy is part of this agreement.

DrawStack is construction draw management software. It helps general contractors and developers build a schedule of values, assemble draw requests, attach invoices and waivers, run an AI review, and produce a lender-ready packet in the AIA G702 and G703 format. Lenders and subcontractors can receive and act on what you send them without holding an account.

DrawStack is a document and workflow tool. To be unambiguous about it:

• We are not a lender, broker, escrow agent or payment processor for your draws. No construction loan money moves through DrawStack. Your lender funds your draws on its own terms and timetable.
• We do not give financial, legal, accounting or engineering advice. Nothing DrawStack produces is a certification, an audit opinion, or a substitute for your own professionals.
• We do not decide whether a draw is approved. Your lender does.
• Lien waivers, notices and retainage rules are jurisdiction-specific. The templates and calculations in DrawStack are a starting point. Confirm them against the law of the state you are building in.

• You need an account to use the product. Keep your credentials confidential — you are responsible for what happens under your account.
• Your data lives in an organization. Whoever creates it controls it, decides who joins, and sets each member's role. Members can see the organization's projects according to that role.
• When you invite a lender, subcontractor, owner or inspector, you are directing us to give that person access to the specific record you shared. You are responsible for who you send links to, and for having the right to share what is in them.
• You must be 18 or older and legally able to enter a contract.
• Tell us promptly at support@drawstack.ai if you think someone has gained unauthorised access to your account.

Do not use DrawStack to:

• Break the law, or help anyone else break it.
• Upload content you do not have the right to upload, or that infringes someone else's rights.
• Submit information you know to be false in a draw request, invoice or waiver.
• Upload malware, or attempt to breach, probe or overload our systems or another customer's data.
• Reverse engineer the platform, scrape it, or resell access to it.
• Use the service to build a competing product.
• Upload sensitive categories we do not ask for — government identification numbers, health records, payment card numbers or biometric data.

We may suspend access immediately if we believe conduct is causing harm, and we will tell you why.

• You own your project data, draw applications, financial records and uploaded documents. Using DrawStack does not transfer ownership of any of it.
• You grant us a limited licence to host, copy, transmit, format and process that content — only as far as is needed to operate the service for you, keep it secure, and comply with the law. The licence ends when you delete the content or close the account.
• We do not sell your data, and we do not use your project or financial data to train AI models.
• You can export your data at any time while your account is open, and for 90 days after it closes. How long we keep things is set out in the Privacy Policy.
• We may use aggregated, de-identified statistics — figures that cannot identify you, your projects or your counterparties — to operate and improve the service.

DrawStack uses AI to parse invoices, audit draws, compare bid scopes and draft correspondence. Those features send the documents you run them on to third-party model providers, described in the Privacy Policy.

• AI output is a draft and can be wrong. It may miss a problem or flag one that is not there.
• You are responsible for reviewing anything before you send it to a lender, a sub or an owner, and for the accuracy of what you submit.
• An AI draw audit is not an approval, a certification, or professional advice.
• As between you and us, output generated from your content is yours, subject to these Terms.

We aim to keep DrawStack available, but we do not promise uninterrupted service. Maintenance, provider outages and events outside our control all happen.

The product changes. We add features, and occasionally we remove one. If we remove or materially reduce a feature you rely on, we will give you at least 30 days' notice by email where practical. Features labelled beta, preview or early access may change or disappear without notice, and are provided as-is.

The DrawStack platform, software, design, brand and documentation belong to DrawStack, Inc. and are protected by intellectual property law. You get a non-exclusive, non-transferable right to use the service under these Terms — nothing more. Do not copy the platform, create derivative works from it, or use our name or logo without written permission. If you send us feedback, we may use it without obligation to you.

DrawStack runs on third-party infrastructure and connects to third-party services, each listed in the Privacy Policy. We choose them carefully and hold them to contractual terms, but we do not control them and are not responsible for their acts or omissions. If you connect an external service to DrawStack, your use of it is governed by that provider's terms.

TO THE MAXIMUM EXTENT PERMITTED BY LAW, THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE", WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, SECURE OR ERROR-FREE, OR THAT ANY OUTPUT — INCLUDING AI OUTPUT, CALCULATIONS AND GENERATED DOCUMENTS — WILL BE ACCURATE OR COMPLETE. Some jurisdictions do not allow the exclusion of certain warranties, so parts of this section may not apply to you.

TO THE MAXIMUM EXTENT PERMITTED BY LAW, NEITHER PARTY IS LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL OR PUNITIVE DAMAGES, OR FOR LOST PROFITS, LOST REVENUE, LOST DATA, LOST BUSINESS OR LOSS OF GOODWILL, ARISING OUT OF OR RELATING TO THE SERVICE, EVEN IF ADVISED OF THE POSSIBILITY.

TO THE MAXIMUM EXTENT PERMITTED BY LAW, DRAWSTACK'S TOTAL AGGREGATE LIABILITY ARISING OUT OF OR RELATING TO THESE TERMS OR THE SERVICE WILL NOT EXCEED THE GREATER OF (A) THE FEES YOU PAID US IN THE TWELVE MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM, OR (B) ONE HUNDRED US DOLLARS.

These limits do not apply to a party's fraud, wilful misconduct, or gross negligence, to your obligation to pay fees, or to anything that cannot be limited by law. Some jurisdictions do not allow these limitations, so parts of this section may not apply to you.

You will defend and indemnify DrawStack against third-party claims, and the reasonable costs and damages that come with them, arising from your content, your use of the service in breach of these Terms or the law, or your sharing of a record with someone who should not have received it. We will tell you promptly about any such claim, let you control the defence, and cooperate with you at your expense.

• You can close your account at any time from your settings.
• We may suspend or terminate an account for a material breach of these Terms, for non-payment, or where we are required to by law. Except in an emergency or where the law prevents it, we will give you notice and a reasonable chance to put it right.
• Exporting your data: your data stays available for export for 90 days after the account closes. After that it is deleted on the schedule in the Privacy Policy. Ask for an export at any time at support@drawstack.ai.
• Sections that by their nature should survive termination do — ownership, disclaimers, liability limits, indemnification and governing law.

We may update these Terms. When we do, we change the effective date at the top of this page. For material changes we will give account holders at least 30 days' notice by email before they take effect. If you keep using DrawStack after that date, the updated Terms apply. If you do not accept them, close your account before the date and tell us — we will refund any prepaid fees for the period you will not use.

These Terms are governed by the laws of the Commonwealth of Massachusetts, without regard to its conflict-of-law rules. The state and federal courts of Massachusetts have exclusive jurisdiction, and both parties consent to venue there. Before filing anything, email support@drawstack.ai — most disagreements are faster to resolve in a conversation.
