Privacy Policy for StressFlow

Last Updated: August 18, 2026

StressFlow ("we," "our," or "the app") is committed to protecting your privacy. This Privacy Policy explains our data practices and confirms our compliance with Google Play Developer Program Policies.

1. Information Collection and Use

StressFlow is designed with privacy by design:

• No Personal Data Collection: We do not collect, process, store, or transmit any Personally Identifiable Information (PII), such as names, email addresses, phone numbers, or physical addresses.

• No User Accounts: You can access all features of the application without registration, account creation, or login credentials.

• No Tracking or Analytics: The application does not integrate third-party analytics SDKs, advertising frameworks, or persistent identifiers used for behavioral tracking.

2. On-Device Processing

• All structural engineering calculations, simulations, and data modeling are executed entirely locally on your device hardware.

• No simulation data, inputs, or generated outputs are uploaded to external servers, cloud storage, or remote databases.

3. Device Permissions & Local Storage

StressFlow requests minimal device access strictly necessary for core offline functionality:

• Local Storage / App Preferences: Used exclusively to store user-selected configurations locally on the device (e.g., UI theme preferences, unit systems).

• Restricted Permissions: The app does not request or access sensitive device permissions, including Location, Camera, Microphone, Contacts, Phone State, or External Media.

4. Third-Party Disclosures

Because we do not collect any user data, we do not sell, trade, rent, or transfer any information to third parties, advertising networks, or data brokers.

5. Children’s Privacy & Families Policy Compliance

StressFlow does not collect personal data from any user, including children under the age of 13 (or the applicable age limit in your jurisdiction). The app complies fully with Google Play’s Families Policy and the Children's Online Privacy Protection Act (COPPA).

6. Disclaimer & Educational Purpose

StressFlow provides structural simulations intended solely for educational, academic, and demonstrative use. Output data should not be used as a substitute for certified professional engineering analysis or safety-critical structural design.

7. Changes to This Privacy Policy

We may update our Privacy Policy periodically to reflect app updates or legal requirements. Any modifications will be posted on this page with an updated revision date and made accessible within the application settings.
