Privacy Policy

Last updated: May 3, 2026

Structural Design Kit respects your privacy. This policy explains how the Structural Design Kit mobile app and website handle information.

1. No required sign-in

The app does not require you to create an account or sign in to use the main calculation tools.

2. Calculation inputs and reports

Design inputs and calculation results are used to generate results and PDF reports. Project inputs are processed for the purpose of app functionality. Avoid entering unnecessary personal information in project fields.

3. PDF files

PDF reports generated by the app may include the design inputs, outputs, drawings, and notes you choose to generate. You are responsible for reviewing reports before saving, sharing, or relying on them.

4. Analytics

The app may use Firebase Analytics or similar analytics services to understand app usage, feature interactions, calculation completion, PDF generation, purchase events, and general performance. This helps improve reliability and future features.

5. Advertising

The app may use Google Mobile Ads / AdMob to show banner ads or rewarded ads. Advertising providers may collect or receive device identifiers, IP address, app activity, diagnostics, and similar data to provide, measure, and improve ads according to their own policies and applicable consent requirements.

6. In-app purchases and subscriptions

The app may offer premium subscriptions or in-app purchases. Payment processing is handled by Apple App Store or Google Play, depending on your device and purchase method. We do not directly collect or store your full payment card details.

7. Third-party services

The app may use third-party services for analytics, advertising, crash/performance diagnostics, app distribution, and purchase processing. These services process data under their own privacy policies.

8. Data selling

We do not sell your personal information.

9. Children

The app is not directed to children under 13. If you believe a child has provided personal information, contact us so we can take appropriate action.

10. Security

We use reasonable safeguards for information handled through the app and website. No method of transmission or storage is completely secure.

11. Engineering disclaimer

Structural Design Kit provides calculation assistance and reporting tools. It is not a substitute for professional engineering judgment, applicable codes, site-specific investigation, or review by a qualified/licensed engineer where required.

12. Changes

We may update this Privacy Policy from time to time. Updated versions will be posted on this page with a revised date.
