Acceptance of terms
These Terms of Service ("Terms") form a binding agreement between you and Tradewind Ops LLC ("we," "us," or the "Company"), the operator of Redline (the "Service"). By creating an account, signing in, uploading content, or otherwise using the Service, you agree to these Terms. If you do not agree, do not use the Service.
You must be at least 18 years old and have authority to enter into this agreement on your own behalf or on behalf of the entity you represent. If you are using the Service on behalf of an employer or client, you represent that you have authority to bind that party to these Terms.
Description of service
Redline is a web-based tool that uses artificial intelligence to assist licensed professional engineers and engineering staff in reviewing mechanical, electrical, and plumbing (MEP) construction drawings. The Service identifies potential defects, code references, and coordination issues for the user's review.
The Service is offered as a review aid. It does not replace, and is not intended to replace, the professional judgment, sealed review, or independent verification of a licensed engineer. See Section 5 for further important information about the use of AI output.
We may add, modify, or remove features at any time. We may also impose usage limits to protect the Service.
Your account
You are responsible for:
- Keeping your login credentials confidential
- All activity that occurs under your account, whether or not authorized by you
- Providing accurate registration information and keeping it current
- Promptly notifying us if you suspect unauthorized access at support@redline.best
You may not share your account or transfer it to another person. We may suspend or terminate accounts that we reasonably believe to be compromised or in violation of these Terms.
Acceptable use
You agree not to:
- Upload any content you do not have a right to upload, including drawings or files that infringe a third party's intellectual property or violate confidentiality obligations
- Upload malware, viruses, or any code intended to disrupt the Service
- Use the Service to violate any law or regulation, including export-control laws
- Attempt to reverse-engineer, decompile, or extract source code from the Service
- Use automated scraping or scripts to access the Service in ways not permitted by its interface
- Resell, sublicense, or commercially redistribute access to the Service without our written consent
- Use the Service to generate output that would be used to defraud, mislead, or harm any person
- Probe, scan, or attempt to bypass any security or access controls
AI output and engineer responsibility
The Service uses large language models and other artificial intelligence systems to analyze drawings and generate output. AI systems can make mistakes. The output of the Service may:
- Identify defects that are not actually defects (false positives)
- Miss defects that are present in the drawing (false negatives)
- Cite codes or standards incorrectly, including incorrect section numbers or out-of-date editions
- Misidentify the location of issues on a drawing
- Generate confident-sounding but inaccurate explanations
You, the licensed engineer, are solely responsible for the use of any output from the Service. The Service is a review aid only. Nothing produced by the Service constitutes engineering advice, a code-compliance determination, or stamped engineering review. Any drawing that you stamp, sign, or release for construction remains your professional responsibility under your professional engineer license.
You agree to independently verify any output from the Service before relying on it, taking action on it, communicating it to a client, or incorporating it into work product. You agree not to represent any output from the Service as the sole or independent basis for an engineering opinion.
We make no representation that the output of the Service is accurate, complete, fit for any particular purpose, or compliant with any applicable code, standard, or jurisdiction. Accuracy figures, benchmarks, or comparative statistics described elsewhere are aspirational and do not constitute warranties.
The Service is not certified to any specific information-security or engineering-quality standard. The Service is not intended for use in life-safety, medical, nuclear, defense, aviation, or any other high-consequence application where errors could cause death, serious injury, or substantial property damage, except under the independent judgment of a licensed engineer who assumes full responsibility for verification.
Your content and our IP
Your content
You retain all ownership rights in the drawings, project information, and other content you upload to the Service ("Your Content"). By uploading Your Content, you grant us a worldwide, non-exclusive, royalty-free license to host, store, process, transmit, display, and analyze Your Content solely for the purpose of operating and improving the Service.
We will not sell Your Content, use Your Content to train third-party AI models, or share Your Content with third parties except as described in our Privacy Policy.
You represent and warrant that you have the right to upload Your Content and to grant the license described above, and that Your Content does not violate the rights of any third party.
Aggregated and anonymized data
We may generate aggregated, anonymized, or statistical information from Your Content and other usage of the Service. This information does not identify you, your clients, or specific projects, and we may use it without restriction to operate, improve, and describe the Service.
Our IP
The Service, including its software, design, copy, and brand, is owned by us or our licensors and is protected by copyright, trademark, and other laws. We grant you a limited, non-exclusive, non-transferable, revocable license to use the Service in accordance with these Terms. No other rights are granted.
Fees, plans, and billing
The Service is sold as a subscription plan. Each plan includes a set number of drawing reviews per billing period, as published on our pricing page. The plan you select at checkout, together with these Terms, forms your subscription agreement.
Billing and automatic renewal
Subscriptions renew automatically. When you purchase a plan, you authorize us and our payment processor to charge your payment method the then-current plan fee at the start of each billing period, on a recurring basis, until you cancel. Monthly plans renew every month on the anniversary of your purchase date. Annual plans renew every twelve months on the anniversary of your purchase date.
You will be charged the full plan fee at the start of each period, whether or not you use any of the drawing reviews included in that period.
Review pools
Each plan includes a pool of drawing reviews for the billing period. A review is drawn from your pool when a run starts. If a run fails for technical reasons attributable to the Service, it is not counted against your pool. Unused reviews do not roll over and expire at the end of each billing period. Additional reviews purchased beyond your plan pool are billed at the per-review rate published for your plan.
Price changes
We may change plan pricing. We will give you at least thirty (30) days' notice by email before a price change takes effect for your account. A price change applies at your next renewal after the notice period. If you do not accept the new price, you may cancel before that renewal date. Continued use after the change takes effect constitutes acceptance of the new price.
Taxes
Published prices are in U.S. dollars and exclude sales, use, VAT, GST, and other applicable taxes. You are responsible for all such taxes, other than taxes on our net income.
Payment method and failed payments
You must keep a valid payment method on file. If a charge fails, we may retry it, and we may suspend your access to the Service until payment succeeds. Accounts that remain unpaid may be terminated in accordance with the Termination section. You remain responsible for amounts that accrued before termination.
Payments are processed by a third-party payment processor. We do not store your full payment card number. See our Privacy Policy for how billing information is handled.
Refunds and cancellation
Monthly money-back guarantee
If you subscribe to any monthly plan (Starter, Pro, or Firm), we will refund your first payment in full provided that you request the refund within fourteen (14) days of that payment and you have started two (2) or fewer drawing reviews on the account.
This guarantee applies to the first payment on a new subscription only. It does not apply to renewals, to a plan changed from another tier, or to a second subscription created by the same customer or firm. It is available once per customer. Runs that fail for technical reasons attributable to the Service do not count toward the two-review limit. On refund, the subscription is cancelled and access to the Service ends.
To claim it, email support@redline.best from the address associated with the account.
All other fees are non-refundable
Except for the monthly money-back guarantee described above, all fees paid for the Service are non-refundable, except where a refund is required by applicable law. This includes, without limitation:
- Fees paid on annual plans of any tier, which are not refundable on a prorated basis
- Fees for any renewal following your first payment
- Fees for a monthly plan where the fourteen-day window has passed or a third review has been started
- Fees for additional reviews purchased beyond your plan pool, which are consumed on purchase
- Fees for partial billing periods, including where you cancel or your account is terminated part-way through a period
- Fees for drawing reviews that go unused and expire at the end of a billing period
- Fees for periods in which you were subscribed but did not use the Service
How to cancel
You may cancel your subscription at any time from your account billing settings, or by emailing support@redline.best. There is no cancellation fee and no minimum term.
Cancellation takes effect at the end of your current billing period. It stops the next automatic renewal charge. It does not refund the period you are already in. You keep full access to the Service, and to the reviews remaining in your pool, until the end of that period.
Cancellation by us
If we terminate your account for violation of these Terms, no refund is due. If we discontinue the Service entirely, we will refund the unused portion of any prepaid annual plan on a prorated basis for whole remaining months.
Billing errors
If you believe you have been charged in error, contact support@redline.best within sixty (60) days of the charge. We will investigate and, where we confirm an error, correct it. This is separate from the no-refund policy above and applies to duplicate charges, charges after a valid cancellation, and charges at the wrong rate.
Disclaimer of warranties
The Service is provided on an "as is" and "as available" basis without warranties of any kind, whether express, implied, or statutory. To the maximum extent permitted by law, we disclaim all warranties, including implied warranties of merchantability, fitness for a particular purpose, non-infringement, accuracy, and uninterrupted or error-free operation. We do not warrant that the Service will meet your requirements, that defects will be corrected, or that the output of the Service is accurate or reliable.
Limitation of liability
To the maximum extent permitted by law, in no event will we be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, including loss of profits, loss of business, loss of data, loss of goodwill, work stoppage, computer failure, or any other commercial damages or losses, arising out of or related to your use of the Service, even if we have been advised of the possibility of such damages.
Our total cumulative liability arising out of or related to the Service, regardless of the form of action, will not exceed the greater of (a) the amount 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 limitation of certain damages; in those jurisdictions our liability is limited to the maximum extent permitted by law.
Indemnification
You agree to indemnify and hold us harmless from any claim, loss, damage, liability, or expense (including reasonable attorneys' fees) arising out of (a) Your Content, (b) your use of the Service in violation of these Terms or applicable law, (c) your use of the output of the Service in any engineered work product, or (d) your violation of any third-party right. We reserve the right, at our own expense, to assume the exclusive defense and control of any matter for which you are required to indemnify us.
Termination
You may stop using the Service at any time and delete your account by contacting us. We may suspend or terminate your access to the Service at any time, with or without notice, if we reasonably believe you have violated these Terms or applicable law, or to protect the Service or other users.
Sections that by their nature should survive termination, including Section 5 (AI output), Section 6 (IP), Section 8 (Refunds and cancellation), Section 9 (Disclaimer), Section 10 (Liability), Section 11 (Indemnification), and Section 13 (Governing law), will survive any termination.
Governing law
These Terms are governed by the laws of the State of Florida, without regard to its conflict-of-laws principles. Any dispute arising out of or related to these Terms or the Service that is not resolved informally will be brought exclusively in the state or federal courts located in Florida, and you consent to the personal jurisdiction of those courts.
This section does not affect any non-waivable rights you may have under the laws of the state where you reside.
Changes to these terms
We may update these Terms from time to time. When we do, we will revise the "Last updated" date at the top of this page and, for material changes, post a notice in the Service or send you an email. Continued use of the Service after a change indicates your acceptance of the revised Terms. If you do not accept the revised Terms, you must stop using the Service.
