By downloading, installing, creating an account for, or using the Craftmetry mobile or web application (the "Service"), you agree to be bound by these Terms of Use. If you do not agree, do not use the Service.
Craftmetry is a reference and quick-sizing toolkit for jobsite professionals (gas, plumbing, electrical, framing). It surfaces values from published codes and manufacturer tables (NFPA 54, NEC, IPC, IRC, and product manuals) along with calculators that apply those values to common sizing problems.
Craftmetry is a reference aid, not engineered design and not a substitute for professional judgment. All work derived from the App must be verified against the governing edition of the applicable code, the actual manufacturer's installation manual, and the requirements of the authority having jurisdiction (AHJ). You are solely responsible for the safety and code-compliance of any work you perform.
You may use the iPhone app's initial preview without an account. The website requires an account before you can open a tool. If you create or sign in to a Craftmetry account, you are responsible for providing accurate information, keeping your credentials secure, and notifying us of unauthorized use. Do not share your account or use another person's account without permission.
A signed-in account can connect eligible Craftmetry Pro access and supported saved calculations or planner layouts between the website and mobile app. Sync is a convenience feature, not a backup service. Keep any independent records you need for your work. You are responsible for the information you save and should not put sensitive personal information in saved work.
You may initiate account deletion inside the iPhone app under About & Support. Deleting your Craftmetry account does not cancel a subscription purchased through Apple or Stripe, and locally stored work remains on your device unless you clear it separately.
Craftmetry offers limited preview access. After the applicable preview or trial, continued access to tools requires an active Craftmetry Pro subscription or other access we expressly provide. Available plans, prices, any applicable tax, trial eligibility, and renewal terms are shown in the App Store or at web checkout before you complete a purchase.
Cancel an iPhone subscription through your Apple ID subscription settings. Cancel a web subscription through the Craftmetry web account's Manage billing link, which opens Stripe's customer portal. Cancellation stops a future renewal but normally does not end access already paid for.
Refunds are handled by the payment provider and applicable law: Apple reviews App Store refund requests, and Stripe-related web billing questions may be sent to us at the contact address below. We do not guarantee refunds except where required by law or a payment provider's policy.
You agree not to:
You retain your rights in the information you enter into calculators and saved layouts. You grant us the limited permission needed to store, transmit, and process that information solely to operate sync and provide the Service.
The App, including its interface, calculators, code, and documentation, is owned by the developer and licensed to you on a personal, non-exclusive, non-transferable, revocable basis for your own professional or personal reference use. Code data referenced inside the App (NFPA, NEC, IPC, etc.) remains the property of its respective publisher.
The App is provided "as is" and "as available" without warranties of any kind, express or implied, including but not limited to warranties of merchantability, fitness for a particular purpose, accuracy, or non-infringement. While we work to keep reference values current and correct, codes are revised periodically and clerical errors are possible. Always verify against the governing code edition and manufacturer documentation before relying on any output.
To the maximum extent permitted by law, in no event shall the developer be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of profits, revenue, data, or business opportunity, arising out of or in connection with your use of the App, even if advised of the possibility of such damages. The developer's total cumulative liability for any claim arising from these Terms or the App shall not exceed the amount you paid for the App in the twelve (12) months preceding the claim.
We may update these Terms from time to time. Material changes will be reflected by updating the "Last updated" date at the top of this page. Your continued use of the App after a change constitutes acceptance of the revised Terms.
These Terms are governed by the laws of the United States and the state in which the developer is domiciled, without regard to conflict-of-laws principles. Questions about these Terms can be sent to support@corvora.app.
