WHITECALC PRODUCTIVITY / PRIVACY

Privacy Policy

Last updated: October 2026

Privacy Overview

WhiteCalc Productivity is a local-first calculator designed to work on your device. Normal use does not require an account or an internet connection.

Information Collection

Michelberger Bau does not collect personal user information through normal use of WhiteCalc Productivity. The app does not require a name, email address, phone number, password or user profile.

App Data

Calculations, calculation history, favorites and app preferences are intended to remain on the user’s device. They are not maintained by Michelberger Bau in a server-side calculation database.

Local Storage

History, favorites and preferences may be stored locally by the app on the device so the user can reuse results and settings.

Website Data

This static website does not provide user accounts, login, registration or a profile system. Michelberger Bau does not use this website to create a personal user database.

Third-Party Services

The website links to Google Play. When you follow that link, Google’s own terms and privacy practices apply to your interaction with Google Play.

Security

The local-first design reduces the need to transmit calculation data to Michelberger Bau. Users should still protect their own device and operating-system access.

Data Retention

No personal user data is retained by Michelberger Bau through normal use of WhiteCalc Productivity. Michelberger Bau does not maintain user profiles, cloud account data, calculation-history databases or server-side favorite calculations for normal app use.

Data Deletion

Because Michelberger Bau does not maintain a cloud user-profile database for normal app use, there is normally no server-side personal profile requiring deletion. Local app data can be removed using available app controls or by uninstalling the app, where applicable. If you voluntarily contact Michelberger Bau by email, you may request deletion of information contained in that correspondence where legally applicable.

Children

WhiteCalc Productivity is a general utility and is not designed to create accounts or profiles for children.

Policy Changes

This policy may be updated when the product or legal requirements change. The revision date on this page will be updated when changes are published.
