Privacy Policy

1.1 Covered Websites and Services. This Privacy Policy applies to any website operated by Company, including but not limited to theslabdesigner.com (the Company's corporate website) and slabs.design (where our software application, known as Slabs, is hosted), together with any subdomains of those domains and any other website, application, or service operated by Company that links to this Privacy Policy (collectively, the "Website"). The software application is referred to as the "Application." Collectively, the Website, the Application, and all related services we provide are referred to as the "Services."

1.2 Geographic Availability. The Services are intended for use by professionals located in the United States and select international markets. The Services are not directed to and are not intended for residents of the European Economic Area (EEA), the United Kingdom, or Switzerland. We do not knowingly collect personal information from individuals in those regions. If you are located in the EEA, UK, or Switzerland, please do not use the Services or provide us with personal information. If you nonetheless use the Services from those regions, Section 9 of this Privacy Policy describes your rights under applicable law and the limited basis on which we process your information.

We collect the following categories of information:

2.1 Information You Provide Directly. When you register for an account, request access, or use the Services, we collect information you provide to us, which may include:

Contact information (required):

• Name
• Company
• Job title
• Work email address
• Phone number
• City, state, and country

Professional credentials (optional):

• States or countries in which you are licensed to practice
• Engineering discipline (e.g., Civil, Structural, Geotechnical, Pavement, Other)
• Years of professional experience

Business relationship information (optional):

• Contractors and owners you currently work with
• Contractors and owners you would like to work with

You may choose not to provide the optional professional credentials and business relationship information. If you do not provide the required information (such as your email address and name), we may not be able to provide you with access to the Services.

2.2 Project and Design Data ("Inputs" and "Outputs"). When you use the Application, you enter engineering design parameters, project locations, and other project-related information (collectively, your "Inputs"), and the Application generates design results, calculations, and reports (collectively, "Outputs"). Inputs and Outputs may include:

• Project names, descriptions, and addresses
• Design parameters (slab dimensions, load conditions, soil properties, materials, etc.)
• Calculations, results, and reports generated by the Application

You acknowledge that Inputs and Outputs may include sensitive, proprietary, or project-specific engineering information. While we take commercially reasonable steps to protect such information, the Services do not create any professional duty of confidentiality between you and Company. We may use aggregated and de-identified Inputs and Outputs to improve the Services as described in Section 3(f).

2.3 Automatically Collected Information. When you access the Services, we and our service providers automatically collect certain information, which may include:

• Pages viewed and features used
• Authentication logs (login events, session information)

2.4 Cookies and Similar Technologies. We and our service providers use cookies and similar technologies (such as session storage and local storage) to operate and secure the Services, remember your preferences, and analyze how the Services are used. You can control cookies through your browser settings. If you disable cookies, some features of the Services may not function properly.

We use the information we collect for the following purposes:

1. to create and manage your account, authenticate you, and provide you with access to the Services;
2. to operate, maintain, secure, monitor, and improve the Services;
3. to respond to your requests, inquiries, and support needs;
4. to verify your professional credentials when relevant to the Services we provide you;
5. to communicate with you about the Services, including service announcements, updates, security notices, and administrative messages;
6. to analyze usage of the Services, develop new features, and improve our proprietary technology, including our neural network models (using aggregated or de-identified data only);
7. to identify potential business introductions that may benefit you, based on the professional credentials and business relationship information you choose to provide. We will contact you before making any introduction, and you may decline or remove this information at any time;
8. to detect, prevent, and respond to fraud, abuse, security incidents, and other harmful activity;
9. to comply with applicable laws, regulations, and legal obligations; and
10. to enforce our Terms of Use and other agreements.

We do not currently send marketing communications, and we do not sell your personal information to third parties.

We share your information only in the following circumstances:

4.1 Service Providers. We share information with third-party service providers who perform services on our behalf. These providers are authorized to use your information only as necessary to provide services to us and are contractually obligated to protect it. Our primary service providers include:

4.2 Business Introductions (With Your Consent). If we identify a potential business introduction based on the optional professional credentials and business relationship information you provide, we will contact you first and obtain your consent before sharing your information with the other party.

4.3 Legal Requirements. We may disclose your information if required to do so by law, regulation, subpoena, court order, or other legal process, or if we reasonably believe disclosure is necessary to (a) protect the rights, property, or safety of Company, our users, or others; (b) investigate or prevent fraud, abuse, or security incidents; or (c) enforce our Terms of Use.

4.4 Business Transfers. If Company is involved in a merger, acquisition, financing, reorganization, bankruptcy, or sale of assets, your information may be transferred as part of that transaction. We will notify you by email or a prominent notice on the Website if such a transfer occurs and your information becomes subject to a materially different privacy policy.

4.5 With Your Direction. We may share your information with third parties when you direct us to do so or when you publicly post information through a Service feature.

5.1 Storage Location. Your account and authentication data are stored by Auth0. Your project data (Inputs and Outputs) is stored by Supabase. Our primary infrastructure is hosted in the United States. Data may be processed or stored in other countries where our service providers operate.

5.2 Security Measures. We use commercially reasonable administrative, technical, and physical safeguards to protect your information against unauthorized access, use, alteration, and destruction. These include encryption of data in transit, access controls, and authentication requirements. No method of transmission or storage is 100% secure, however, and we cannot guarantee absolute security.

5.3 Data Breach Notification. In the event of a data breach that affects your personal information, we will notify you and applicable regulators as required by law.

We retain your information for as long as your account is active or as needed to provide the Services. If you delete your account, we will retain your information for up to one (1) year after deletion for the following purposes:

• To resolve disputes or enforce our agreements;
• To comply with legal and regulatory obligations;
• To maintain backups in accordance with our standard data-retention practices; and
• For security and fraud-prevention purposes.

After this retention period, we will delete or de-identify your information. Notwithstanding the foregoing, we may retain Inputs, Outputs, and related records for a longer period to the extent necessary to defend against or resolve any actual or threatened claim arising from or relating to an Output generated during your use of the Services or any facility or structure designed, constructed, or maintained based on such Output, for the full duration of any applicable statute of limitations or statute of repose. De-identified and aggregated data that cannot reasonably be linked to you may be retained indefinitely for analytics and product improvement purposes.

7.1 Access and Update. You may access and update your account information at any time by logging into the Application.

7.2 Deletion. You may request deletion of your account by contacting us at info@theslabdesigner.com. We will process your request within a reasonable time, subject to the retention period described in Section 6.

7.3 Opt-Out of Business Introductions. You may opt out of receiving potential business introductions at any time by updating your profile or contacting us at info@theslabdesigner.com.

7.4 Communications. You may opt out of non-essential communications by following the unsubscribe instructions in those communications. You cannot opt out of service-essential communications (such as security notices or account updates) while you maintain an active account.

7.5 Do Not Track. Some browsers offer a "Do Not Track" signal. Because there is no industry-standard interpretation of this signal, the Services do not currently respond to Do Not Track signals.
