10. DrND SolutionLab app for Android

Effective date: 19 October 2026

This section applies to the DrND SolutionLab app for Android (package name com.drndsknowledgehub.solutionlab), published on Google Play by DrND's Knowledge Hub. For the app, this section takes precedence over the rest of this privacy policy. The other sections, including those about cookies, analytics, payments and accounts, describe our website and are not features of the app.

Who the app is for. DrND SolutionLab is a solution-preparation and dilution calculator for school students aged 13 and older, college and university students, educators and laboratory professionals. It is not designed for children under 13.

Information the app collects. The app is designed not to collect personal or sensitive information. It does not intentionally transmit calculator entries or other information to the publisher, and we do not sell or share information from the app. It has no accounts or sign-in, and it does not include advertising, analytics, tracking or crash-reporting software.

What you enter. The app is designed to perform calculations on your device. The values you type are kept in the app's memory while it is open, so your work is not lost when you switch calculators or rotate the screen. The app does not save them to storage, and they are cleared when the app is closed, either by you or by Android. Your keyboard and any autofill service you have chosen are part of your device's system and operate under their own terms. The app's input fields ask Android not to autofill them.

Network use. The calculator is designed to work without an internet connection, and the app does not make network requests of its own. Android's standard internet permission is included as part of the app's framework.

Links to our website. Links such as "Back to DrND's Knowledge Hub", "All tools", "Disclaimer" and "Privacy" open in your device's web browser, outside the app. Your use of our website is covered by the rest of this privacy policy.

Printing and PDF files. "Print worksheet" passes the worksheet shown on your screen to Android's printing system. You choose the printer, or "Save as PDF" and where to save the file. The app is not designed to keep a copy of the worksheet or to send it anywhere. A printing service you choose handles the document under its own terms.

Information stored on your device. The app's framework stores the installed app version in the app's private storage so it can recognise updates. Android's web engine may also keep its own internal working files there. These are not used to store your entries. The app does not set cookies, and Android backup of the app's data is turned off.

Retention and deletion. Because the app is designed not to send us information, we do not hold app data to retain or delete. Uninstalling the app removes the app and the local data it manages in its private storage. PDFs or printouts you saved separately are your own files, and they remain in the location you chose until you delete them.

Permissions. The app does not request access to your location, contacts, camera, microphone, photos, files, calendar or other personal data.

Google Play and Android. Google Play and Android may collect information, such as install, update and app-performance information, under Google's own privacy policy. This is separate from the app.

Security. The app is designed to perform calculations on your device without intentionally transmitting calculator entries to the publisher. If you have a privacy concern, please contact us using the details below.

Changes. If a future version changes how the app handles information, we will update this section and the app's Google Play Data safety information before that version is released.
