Privacy Policy

Effective Date: June 28, 2026

This Privacy Policy applies to the mobile application Hydro Vision Calculator, developed and published by SD CodeLabs.

1. Information We Collect

Hydro Vision Calculator does not require users to create an account and does not directly collect personal information such as name, email address, phone number, or location.

2. Calculation Data

The app allows users to enter hydraulic calculation values such as cylinder diameter, pressure, flow rate, motor displacement, pump data, pipe size, and related engineering parameters. These values are used only to calculate results inside the app.

We do not collect, transmit, or sell these calculation inputs or results.

3. Internet and Third-Party Services

The current version of Hydro Vision Calculator does not require login or cloud synchronization. If third-party services such as ads, analytics, crash reporting, or cloud features are added in future versions, this Privacy Policy will be updated accordingly.

4. Permissions

Hydro Vision Calculator may use only the permissions required for normal app functionality. The app does not request sensitive permissions unless required for a specific feature.

5. Data Sharing

We do not sell, rent, or share user personal data with third parties.

6. Data Security

Since the app does not directly collect personal data, no personal user database is maintained by us. Users are responsible for the engineering values they enter and use in calculations.

7. Engineering Disclaimer

Hydro Vision Calculator is designed as a calculation assistance tool for hydraulic and engineering reference purposes. Users should verify results before using them in real-world industrial, safety-critical, or production environments.

8. Children's Privacy

Hydro Vision Calculator is not intended to collect information from children. We do not knowingly collect personal data from children.

9. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated effective date.
