Who we are and what this covers
Carved Stone Interactive operates Construction Calculator for Android (package com.constrcalc.jorsoftpr) and its free edition, Construction Calculator Lite (package com.constrcalculator.jorsoftpr). Contact us at carvedstoneinteractive@gmail.com about privacy. Both are offline estimators for concrete, tile, block, paint and pipe offsets. They have no accounts, no sign-in, no purchases and no cloud save.
Information used by the apps
- Device data: the last numbers you entered in each estimator, so they are there next time. They stay on your device and are never sent to us.
- We do not collect your name, email, contacts, photos, precise location or any account information, and we run no server for these apps.
Construction Calculator (the paid edition) has no ads and makes no network requests. We do not request camera, microphone, contacts or location access in either edition.
Advertising in Construction Calculator Lite
Lite shows one banner at the bottom of the screen, provided by Google AdMob. When ads operate, Google's ad SDK processes IP-derived approximate location, device identifiers such as the advertising ID, ad interactions and diagnostic information for advertising, measurement and fraud prevention.
Where required, consent is requested before ads are shown, and you can decline personalization or change your choice later under Privacy options in the menu. If consent is unavailable or an ad cannot load, the calculator keeps working without ads. Android also offers advertising-identifier controls in its privacy settings.
We do not sell personal data for money. Ad-related sharing for personalized advertising may be considered sale or sharing under some privacy laws; use the consent choices offered or contact us.
Google's privacy information is available at Google Privacy Policy and Google advertising services.
Age
These apps are intended for adults, ages 18 and older.
Retention and deletion
Your entries remain on your device until you clear the app's data or uninstall it. Because we hold no data about you, there is nothing for us to delete on a server. Google applies its own retention to advertising data; see its policies above. For questions or requests, email us; we never ask for passwords or codes.
Changes
We update this page when practices change and revise the date above. Contact: carvedstoneinteractive@gmail.com.
