ConcreteCalc — Privacy Policy
Last updated: June 22, 2026
This Privacy Policy describes how ConcreteCalc (the "App") handles your information. The App is a concrete-estimating calculator published by AxelStack (the "Developer"). Your privacy matters, and the App is designed to need none of your personal data.
The short version
ConcreteCalc does not collect, store, transmit, or share any personal information. It works entirely on your device, offline. There are no accounts, no ads, no analytics, and no trackers.
Information we collect
None. The App does not ask for, collect, or transmit any personal or device information. It does not request access to your location, contacts, camera, photos, microphone, or files.
Information stored on your device
Your preferences — such as units (US/metric), theme, currency, default waste factor, truck capacity, and last-used prices — are saved locally on your device only so the App remembers your settings between sessions. This information never leaves your device and is not accessible to the Developer or anyone else. Removing the App deletes it.
Third-party services
The App does not integrate any third-party analytics, advertising, or data-collection SDKs. It does not require an internet connection to function.
Children's privacy
The App does not collect personal information from anyone, including children under the age of 13. It is a general-purpose tool suitable for all ages.
Purchases
ConcreteCalc is a paid app distributed through the Google Play Store. Any payment is processed by Google under its own terms and privacy policy; the Developer does not receive or store your payment details.
Changes to this policy
This policy may be updated from time to time. Material changes will be reflected by updating the "Last updated" date above.
