Terms of Service

By accessing or using the Service, you agree to be bound by these Terms and by our Privacy Policy, which is incorporated here by reference. If you do not agree, you may not use the Service.

You must be at least 16 years old and able to enter a binding contract to use the Service. You agree to provide accurate information when registering and to keep it current. You can create an account with an email sign-in code or by using Sign in with Google.

• You are responsible for maintaining the confidentiality of your account credentials.
• You are responsible for all activity that occurs under your account.
• Notify us promptly at support@costlogic.co if you suspect unauthorized use of your account.

Some features of the Service require a paid subscription. When you subscribe, you authorize us to charge the applicable fees on a recurring basis until you cancel. Plans, features, and pricing may change, and we will provide reasonable notice before a change affects your account.

Payments are processed by Stripe. You enter your card and payment details directly on Stripe's hosted checkout and billing portal, and that information is handled by Stripe under its own terms. We do not receive or store your full card number.

• Subscriptions renew automatically for the same period unless you cancel before the renewal date.
• You can view your plan, update payment details, and cancel at any time through the billing portal in your account.
• Fees are stated exclusive of taxes, and you are responsible for any applicable taxes.
• Except where required by law, payments are non-refundable, and canceling stops future charges rather than refunding the current period.

You agree to use the Service lawfully and responsibly. You will not:

• Violate applicable law or the rights of others.
• Upload content you do not have the right to share.
• Access accounts, data, or systems you are not authorized to access.
• Interfere with or disrupt the Service, including by introducing malware or bypassing usage or rate limits.
• Reverse-engineer or extract source code except as permitted by law.
• Resell or commercially exploit the Service without our written consent.

You retain ownership of the plans, blueprints, files, measurements, estimates, invoices, and other content you upload or create ("Your Content"). You grant CostLogic a non-exclusive license to host, store, process, transmit, and display Your Content solely to operate and provide the Service to you, including through the service providers described below.

You are responsible for Your Content and for ensuring you have the rights needed to use it within the Service.

CostLogic offers optional AI-assisted features that help you work faster. These features are usage-gated, which means they are subject to plan and usage limits. They are turned on only when you choose to use them, and each one sends only the content needed to deliver that specific feature to a third-party AI provider.

What each AI feature sends

• Auto Room, our room and area detection feature, is powered by Tectly. When you run Auto Room, the image of the drawing or plan page you selected is sent to Tectly so it can detect rooms and areas.
• AI page naming is powered by Fireworks AI. When you use it, the text from your plan pages is sent to Fireworks AI to suggest page names.
• Onyx, our AI assistant, is powered by Fireworks AI. When you send Onyx a message, your project, takeoff, and estimate data along with the chat messages you write are sent to Fireworks AI to generate a response.

These providers process the content you submit under their own terms and privacy practices, and we share only what is needed to provide the feature you requested. We do not control how a third-party provider operates its own systems.

AI output can be incomplete or inaccurate. It is a starting point, not professional advice. You are responsible for reviewing and verifying any AI-generated result before relying on it. If you prefer not to send content to these providers, simply do not use the AI features.

To operate the Service, we rely on a set of third-party service providers that process data on our behalf. We share information with them only as needed to provide the Service, and we do not sell your personal information.

• Supabase provides our database, authentication, and file storage, including the plan and blueprint PDFs you upload.
• Vercel provides application hosting and content delivery, and processes your requests in transit.
• Stripe processes payments for CostLogic subscriptions and collects card and payment details directly on its own hosted checkout and portal.
• Tectly powers the Auto Room detection feature, as described in the AI Features section.
• Fireworks AI powers AI page naming and the Onyx assistant, as described in the AI Features section.
• Resend sends transactional and customer-facing emails, such as estimates and invoices, including their PDF attachments.
• Google provides Sign in with Google authentication when you choose to use it.
• Authentication verification emails, such as sign-in and confirmation codes, are delivered through the email provider configured in our Supabase project.

We do not use analytics, advertising, session-replay, or tracking vendors. Your use of a third-party service may be subject to that provider's own terms, and CostLogic is not responsible for third-party services. See our Privacy Policy for more detail on how information is handled.

The Service, including its software, design, and branding, is owned by CostLogic and protected by intellectual-property laws. We grant you a limited, non-exclusive, revocable license to use the Service in accordance with these Terms. These Terms do not transfer any ownership in the Service to you.

We work to keep the Service available, but we do not guarantee uninterrupted access. We may modify, suspend, or discontinue features at any time. We will use reasonable efforts to notify users of changes that materially affect how they use the Service.

The Service is provided on an "as is" and "as available" basis. To the maximum extent permitted by law, CostLogic disclaims all warranties, whether express or implied, including any implied warranties of merchantability, fitness for a particular purpose, and non-infringement.

CostLogic helps you create takeoffs, estimates, and invoices, but professional judgment is required. You are responsible for verifying measurements, quantities, prices, AI-generated output, and any other results before relying on them for bidding, ordering, or construction.

To the maximum extent permitted by law, CostLogic will not be liable for any indirect, incidental, special, consequential, or punitive damages, or for any loss of profits, revenue, or data, arising from or related to your use of the Service. Our total liability for any claim will not exceed the greater of one hundred U.S. dollars ($100) or the amount you paid CostLogic in the twelve months before the event giving rise to the claim.

You agree to indemnify and hold harmless CostLogic and its officers, employees, and agents from any claims, damages, and expenses, including reasonable legal fees, arising from Your Content, your use of the Service, or your violation of these Terms or of applicable law.

You may stop using the Service and delete your account at any time. We may suspend or terminate access if you breach these Terms or to protect the security or integrity of the Service. Provisions that by their nature should survive termination, including ownership, disclaimers, limitation of liability, and indemnification, will survive.

These Terms are governed by the laws of the State of Delaware, USA, without regard to its conflict-of-laws rules. Any disputes will be resolved in the state or federal courts located in Delaware, and you consent to the personal jurisdiction of those courts.

We may update these Terms from time to time. When we do, we will revise the effective date at the top of this page, and we will communicate material changes in-app or by email where practicable. Continued use of the Service after changes take effect means you accept the updated Terms.
