Privacy Policy for AS SampleCalc

Effective Date: September 19, 2026

AS SampleCalc is a statistics sample size calculator developed to help users perform sample size calculations using various statistical methods.

This Privacy Policy explains how AS SampleCalc handles information when you use the AS SampleCalc Android application and its associated R Shiny web application.

1. Information We Collect

AS SampleCalc does not require users to create an account, sign in, or provide personal information to use the sample size calculator.

The app does not intentionally collect information such as your name, email address, phone number, contacts, photographs, or precise location.

When you use the calculator, the statistical values and parameters that you enter may be transmitted to the R Shiny web application in order to perform the requested calculations and display the results.

Users should avoid entering personally identifiable, confidential, or sensitive information into the calculator fields.

2. Automatically Processed Technical Information

Because AS SampleCalc connects to a web-based R Shiny application, standard technical information may be processed by the web hosting or infrastructure used to operate the service. This may include information such as IP address, browser or device information, timestamps, and technical request information, depending on the hosting service and its logging practices.

This information is used for purposes such as operating, maintaining, securing, and troubleshooting the web service.

AS SampleCalc does not intentionally use such information to identify individual users.

3. How Information Is Used

Information submitted through the calculator is used to:

• perform statistical sample size calculations;

• generate and display calculation results;

• maintain and operate the calculator;

• troubleshoot technical problems and maintain service security.

AS SampleCalc does not sell users' personal information.

4. Data Storage and Retention

AS SampleCalc does not provide user accounts or a personal data storage facility.

Calculation inputs are submitted to the R Shiny application to perform calculations. AS SampleCalc does not intentionally maintain a personal profile or database of individual users.

Technical logs, if generated by the hosting infrastructure, may be retained according to the policies and practices of the service provider hosting the R Shiny application.

5. Third-Party Services

AS SampleCalc uses an R Shiny web application to provide its sample size calculation functionality.

The Android application connects to the web application to provide the calculator interface and functionality.

The web application may be hosted using a third-party hosting service. Such service providers may process technical information necessary to operate and secure the service in accordance with their own policies.

6. Children's Privacy

AS SampleCalc is not specifically directed toward children under the age of 13, and the app does not knowingly collect personal information from children.

7. Data Security

Reasonable measures are used to protect the application and its associated web service. However, no method of transmission over the internet or electronic storage can be guaranteed to be completely secure.

8. External Websites and Services

AS SampleCalc may connect to its associated R Shiny web application to provide calculator functionality.

This Privacy Policy applies to AS SampleCalc. Third-party services connected with or used to host the web application may have their own privacy policies and terms.

9. Changes to This Privacy Policy

This Privacy Policy may be updated from time to time to reflect changes to the application, its services, or applicable requirements.

Any updated version will be published at the same privacy policy webpage.
