Effective Date: September 5, 2026
This Privacy Policy explains how Concrete Calculator (“the App”, “we”, “us”, or “our”) handles information when you use our application.
We respect your privacy and are committed to handling information responsibly and transparently.
Concrete Calculator is primarily a calculation and estimation tool.
You may enter information such as:
Length
Width
Height
Depth
Diameter
Quantity
Measurement units
Other values required to perform concrete calculations
This information is used to generate calculation results.
Unless otherwise stated within the App, calculation data entered into the App is processed for the purpose of providing the requested calculation functionality.
We do not require you to provide your real name, physical address, phone number, or other direct personal identification information simply to use the basic calculation features of the App.
Depending on the version of the App and the services used to operate it, limited technical information may be processed automatically, such as:
Device type
Operating system version
App version
Language or region settings
General device information
Crash logs
Diagnostic information
Performance information
Anonymous or pseudonymous usage information
This information may be used to maintain the App, diagnose technical problems, improve performance, understand feature usage, and improve the user experience.
We do not use this information to determine concrete calculation results.
Measurements and other values entered into the calculator are used to provide the calculation functions requested by you.
Where calculations are performed locally on your device, the entered values do not need to be transmitted to our servers solely to perform those calculations.
Certain information may remain on your device if the App provides calculation history, saved projects, preferences, or similar features.
Removing the App may remove locally stored information, depending on your device settings and operating system behavior.
If the App offers subscriptions or in-app purchases, payments are processed through Apple's App Store.
We do not directly collect or store your complete credit card or bank account information.
Apple may process information relating to your purchase, subscription status, transaction, and Apple ID in accordance with Apple's own privacy policies and terms.
We may receive limited transaction-related information necessary to determine whether you have access to paid features, such as:
Subscription status
Product purchased
Purchase or renewal status
Transaction identifiers
Expiration information
We may use third-party analytics, crash reporting, subscription management, or infrastructure services to help us understand how the App performs and to diagnose problems.
Depending on the services integrated into the App, these providers may process limited technical or usage information on our behalf or under their own applicable privacy terms.
We aim to limit such processing to information reasonably necessary to operate, secure, analyze, and improve the App.
Information processed in connection with the App may be used to:
Provide calculation and estimation features;
Save user preferences or calculation history where applicable;
Provide and verify premium features or subscriptions;
Maintain and improve the App;
Identify bugs, crashes, and technical problems;
Improve performance and usability;
Prevent fraud, abuse, or security incidents;
Respond to customer support requests;
Comply with applicable legal obligations.
We do not sell your personal information for monetary consideration.
We do not share personal information with third parties except where reasonably necessary for purposes such as:
Operating and maintaining the App;
Processing purchases and subscriptions;
Providing analytics or crash reporting services;
Preventing fraud or security incidents;
Complying with legal obligations;
Protecting our rights, users, or services.
Third-party service providers may have their own privacy policies governing how they handle information.
If you use the App on an Apple device, certain information may be processed by Apple in connection with:
App downloads
App Store purchases
Subscriptions
Device services
Crash reporting
App Store functionality
Apple's handling of such information is governed by Apple's own privacy policies and terms.
We retain information only for as long as reasonably necessary for the purposes described in this Privacy Policy, unless a longer retention period is required or permitted by law.
Information stored locally on your device may remain there until you delete it, clear the relevant data, or uninstall the App.
Technical, transaction, or diagnostic information processed through third-party services may be retained according to the applicable provider's retention practices.
We use reasonable technical and organizational measures designed to protect information associated with the App.
However, no electronic storage or transmission method is completely secure, and we cannot guarantee absolute security.
The App is not specifically directed toward children under the minimum age required to consent to data processing under applicable law.
We do not knowingly seek to collect personal information from children through the basic calculation functionality of the App.
If you believe a child has provided personal information to us inappropriately, please contact us so that we can review the matter.
Depending on where you live, you may have certain rights regarding your personal information under applicable privacy laws.
These rights may include the right to:
Request access to personal information;
Request correction of inaccurate information;
Request deletion of certain information;
Object to or restrict certain processing;
Withdraw consent where processing is based on consent;
Request information about how your data is processed.
Some rights may be subject to legal exceptions or may not apply where we do not possess information that can reasonably be linked to you.

Some service providers used by the App may operate in countries or regions other than the one in which you live.
As a result, limited information may be processed in other jurisdictions, subject to applicable legal requirements and appropriate safeguards where required.
We may update this Privacy Policy from time to time to reflect changes to the App, our practices, technology, legal requirements, or third-party services.
When this Privacy Policy is updated, we will revise the effective date shown at the top of this document.
We encourage you to review this Privacy Policy periodically.
