Construction Calculator collects no data. Every calculation runs on your device. The app requires no permissions, makes no network connections, and contains no account system, analytics, or advertising.
We collect no information whatsoever. Specifically:
When you enter dimensions, tile sizes, waste percentages, or other values, they are used only to compute estimates on your device:
Construction Calculator requests no Android permissions. Not camera, not storage, not network, not location — nothing. The app cannot access any data on your device beyond the values you type in.
The app makes no network connections. It does not require an internet connection and does not send or receive any data over a network. It works identically in airplane mode — ideal for use on a job site with no signal.
Construction Calculator uses no third-party services, SDKs, or libraries that collect user data. No advertising networks, no analytics platforms, no crash-reporting services, no cloud providers.
Construction Calculator provides estimates for material quantities (area, concrete volume, tiles, flooring, and bricks). All results are estimates intended to help you plan and order materials.
Material coverage, bag yields, and brick counts vary by manufacturer, product, and site conditions. The app's default values are approximations. Always verify against your specific products and local practices, and add a safety margin. For structural or load-bearing work, consult a qualified engineer or builder.
Because the app collects no data at all, it complies with the Children's Online Privacy Protection Act (COPPA), the EU General Data Protection Regulation (GDPR), and Google Play's Families Policy. No special handling for any age group is required, since no data is collected from anyone.
Under GDPR (EU/EEA), CCPA (California), and similar laws, you have rights to access, correct, delete, or export your personal data. Because Construction Calculator collects and stores no personal data, there is nothing to access, correct, delete, or export. The right is honored by default through our zero-collection design.
If the app's data practices ever change, this policy will be updated and the "Last updated" date will reflect it. Material changes would be noted in the app's release notes on Google Play. The current version is always available at the URL where you are reading this.
