TrussLab is provided as a web application, used in your browser, for structural engineering workflows, including modeling, analysis, optimization, and related tasks.

The Software may include:

• Use of the web application in your browser on authorized devices
• Project files, exports, and outputs you generate and save on your device
• Account sign-in, subscription, and license validation through our online services
• Subscription-based features and limits as described in your plan
• Connection of third-party AI services you authorize

We reserve the right to modify, suspend, or discontinue any part of the Software or related services at any time.

TrussLab offers free trials and paid subscription plans (monthly, yearly, and enterprise or team plans where applicable). Features and limits vary by plan.

4.2 Payment processing

All payments, subscriptions, taxes, and refunds for online subscriptions are processed by Dodo Payments, which acts as the Merchant of Record for those transactions.

• TrussLab does not store or process payment card details

4.3 Renewals

Subscriptions automatically renew unless canceled before the renewal date, as described at purchase or in your account.

You may cancel your subscription at any time through your account or Dodo Payments' customer flows. Cancellation typically takes effect at the end of the current billing period, unless stated otherwise by Dodo Payments or applicable law.

4.5 Refunds and consumer cancellation

Online purchases are processed by Dodo Payments as Merchant of Record. Refunds, consumer cancellation rights, and related terms are governed by Dodo Payments' buyer terms and applicable law.

For details, see Dodo Payments Buyer Terms.

5. Enterprise / Team Accounts (If Applicable)

For enterprise or team subscriptions:

• One or more administrators may manage seats and users
• Administrators can invite, remove, and manage members
• You are responsible for all activity within your organization account
• Seat limits must not be exceeded. Additional seats may require an upgraded subscription.

6. Acceptable Use

• Reverse engineer, decompile, or attempt to extract source code from the Software, except where mandatory law allows
• Bypass subscription limits, license checks, or technical safeguards
• Use any connected service to bypass subscription limits or technical safeguards

7. Project Data and User Content

7.1 Ownership

You retain full ownership of your project data, models, and files you create or store with the Software, and of exported outputs you generate.

7.2 Processing of your models

Projects held in browser storage may be lost if browser data is cleared or the device is changed. TrussLab holds no copy of your projects and cannot recover them. You are responsible for maintaining backups, for example by downloading project files.

7.3 Account and license connectivity

The Software and website may connect to TrussLab or authorized third parties for account sign-in, subscription or license validation, trial activation, checkout, password recovery, support, or optional updates. Those connections may transmit technical and account-related information needed to provide those features—for example, authentication tokens, license status, or a device identifier used for entitlement—not your project files for cloud-based solving.

7.4 No AI or ML training on your engineering content

We do not collect your project data, models, analysis results, or other engineering content for the purpose of training machine-learning or artificial-intelligence models, and such content is not used to improve generalized AI systems. A material change to this practice would require an update to these Terms (or a dedicated notice) and, where required, your consent.

7.5 Responsibility

YOU ARE FULLY AND SOLELY RESPONSIBLE FOR:

• Verifying the accuracy of all outputs before use in any project
• Ensuring full compliance with all applicable engineering standards, building codes, and regulations
• Thoroughly reviewing and validating all analysis results, designs, and documentation
• Conducting independent engineering analysis to confirm the suitability of outputs for your specific project
• All consequences of using TrussLab outputs in actual construction or design projects

7.6 Third-party AI services

The Software permits you to connect third-party AI services of your choosing. Where you elect to do so:

• Such services act on your instruction and under your account. All actions they perform, including changes to models, designs and settings, and any consumption of plan allowances, are deemed to be performed by you.
• TrussLab does not control, endorse or warrant any third-party AI service, and accepts no liability for its actions, outputs or availability.
• Your use of any such service is governed by the provider's own terms of service and privacy policy, which you should review before connecting it.
• Outputs produced with the assistance of any such service are subject to Section 7.5 and must be independently verified in the same manner as all other outputs of the Software.

8. Intellectual Property

You are granted a limited, non-exclusive, non-transferable license to use the Software in accordance with these Terms and your active subscription or license, where applicable.

To the maximum extent permitted by law, we disclaim all warranties, including:
