Information Collection

0

No personal user data is collected or retained by Michelberger Bau through normal use of WhiteCalc Productivity. The app does not require your name, email address, phone number, location, password, account, or profile.

App Data & Local Storage

Calculations, recent history, favorites, labels, and app preferences may be stored locally on your own device so the app can provide its functions. This local app data is not maintained by Michelberger Bau as a remote user profile or cloud calculation database.

Website Data

This privacy page is a static website. It contains no account system, forms, analytics scripts, advertising trackers, or custom database. Your browser and hosting/network providers may process ordinary technical request information as required to deliver the page, but this site does not intentionally build personal profiles from that information.

Third-Party Services

WhiteCalc Productivity does not share app-generated personal data with third parties because normal app use does not collect personal data for Michelberger Bau. If you follow an external link such as Google Play, that external service operates under its own terms and privacy practices.

Security

Because WhiteCalc Productivity is designed around local processing and does not maintain a normal-use personal user database, the amount of personal information exposed to remote systems is minimized. You remain responsible for protecting access to your own device and any local app data stored on it.

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, a server-side calculation-history database, or server-side favorite calculations for normal app use.

Any calculation history, favorites, or preferences saved by the app remain locally on the device unless you remove them.

Data Deletion

Because Michelberger Bau does not maintain a cloud user database for normal use of WhiteCalc Productivity, there is normally no server-side personal profile to delete.

Local app data can be removed using available in-app controls, by clearing the app's local data where supported by the operating system, or by uninstalling the app. If you voluntarily contact Michelberger Bau by email, you may request deletion of personal information contained in that correspondence where legally applicable.

Children

The app is not intended to collect personal information from children. Since normal use does not create an account or transmit personal user data to Michelberger Bau, the app is not designed to build profiles about children. Parents or guardians should supervise device and app use as appropriate.

Policy Changes

This Privacy Policy may be updated when the app, website, or applicable requirements change. The current version will be published on this page with an updated effective date when appropriate.

Effective date: October 21, 2026.
