Privacy Policy for Calzero

Last updated: September 21, 2026

This Privacy Policy explains how Calzero handles information when you use the Calzero Android application.

Calzero is a calculator and conversion application designed to provide calculation tools while keeping its core functionality available without requiring an account or an internet connection.

1. Information You Provide

Calzero does not require you to create an account, sign in, or provide your name, email address, phone number, or other account information to use its calculator features.

Values entered into calculators are used to perform calculations on your device and are not intentionally transmitted by Calzero to a developer-operated server.

2. Information Stored on Your Device

Calzero stores a limited amount of application data locally on your device to support features such as:

• favorite calculators;

• recently used calculators; and

• advertising frequency controls.

This information is used to provide application functionality and manage the frequency of advertisements.

Calzero does not operate its own server for storing this application data.

3. Advertising

Calzero uses Google Mobile Ads to display advertisements.

Advertisements may include banner ads and interstitial ads.

Google Mobile Ads may automatically collect and process information such as:

• IP address, which may be used to estimate general location;

• interactions with the application and advertisements;

• diagnostic and performance information; and

• device and account identifiers, including the Android advertising ID where available.

Google may use this information for purposes including advertising, analytics, and fraud prevention.

The collection and processing of information by Google are governed by Google's applicable privacy policies and advertising policies.

4. Consent and Privacy Choices

Calzero uses Google's User Messaging Platform (UMP) to manage advertising consent where required.

Depending on your location and applicable requirements, you may be presented with a consent message regarding the use of personal data for advertising.

Where required, Calzero also provides access to privacy choices that allow you to review or change applicable advertising privacy preferences.

5. Internet Access

Calzero's core calculator functionality is designed to work without an internet connection.

An internet connection is used by third-party advertising and consent services, including Google Mobile Ads and Google's User Messaging Platform.

If advertising services are unavailable or an advertisement cannot be loaded, the core calculator functionality remains available.

6. Third-Party Services

Calzero uses services provided by Google for advertising and consent management.

These services may collect and process information according to their own terms and privacy policies.

Relevant Google services include:

• Google Mobile Ads;

• Google User Messaging Platform; and

• Google Play services and related components used by the advertising SDK.

You can learn more about Google's privacy practices through Google's Privacy Policy and Google's advertising/privacy documentation.

7. Advertising Identifiers

Google Mobile Ads may use device identifiers such as the Android advertising ID where available and permitted.

Android provides controls that may allow you to reset or delete your advertising ID or otherwise manage advertising-related privacy settings.

Availability of these controls depends on your Android version and device.

8. Data Sharing

Calzero does not intentionally sell personal information.

Information processed through Google Mobile Ads and related Google services may be transmitted to and processed by Google for purposes including advertising, analytics, service delivery, security, and fraud prevention.

Calzero does not independently operate an advertising-data server or user-profile database.

9. Data Security

Data transmitted by the Google Mobile Ads SDK is protected in transit using industry-standard transport encryption provided by the SDK.

Calzero keeps its own Favorites, Recent Calculators, and advertising-frequency information locally within application storage, subject to Android's application security mechanisms and applicable device backup behavior.

No method of electronic storage or transmission can be guaranteed to be completely secure.

10. Data Retention and Deletion

Calzero's locally stored application preferences remain on your device until they are removed through normal application or Android data-management mechanisms, such as clearing the application's data or uninstalling the application, subject to applicable Android backup and restore behavior.

Information processed by Google services is subject to Google's applicable data retention and deletion practices.

Calzero does not maintain user accounts and therefore does not maintain a developer-operated account database requiring a separate account-deletion process.

11. Children's Privacy

Calzero is a general-purpose calculator application and is not specifically designed or directed toward children.

Advertising and data handling may be subject to additional requirements depending on the target audience selected for Calzero in Google Play.

The application's Google Play target-audience configuration should be considered together with this Privacy Policy.

12. Changes to This Privacy Policy

This Privacy Policy may be updated when Calzero's functionality, advertising configuration, third-party services, or applicable requirements change.

When the policy is updated, the "Last updated" date at the top of this page will be revised.
