Privacy Policy

Last updated: September 19, 2026

This Privacy Policy applies to the K Calculator mobile application developed by Vishnu Ugale.

Privacy

K Calculator does not require users to create an account or provide personal information such as their name, email address, phone number, address, contacts, photos, or financial information.

K Calculator itself does not operate a server or database to collect or store users' personal information.

However, the app uses Google AdMob to display advertisements. The Google Mobile Ads SDK may automatically collect and share certain information as described below.

Advertising

K Calculator uses Google AdMob to display advertisements, including banner and interstitial advertisements.

Google AdMob may automatically collect and share certain information from your device and your use of the app. This may include:

• IP address, which may be used to estimate approximate location.

• Advertising or device identifiers.

• Information about interactions with the app and advertisements.

• Diagnostic and performance information.

This information may be used by Google for advertising, analytics, fraud prevention, security, and related services.

For more information, please see Google's Privacy Policy:

Data Sharing

We do not sell or rent users' personal information.

Information collected through Google AdMob may be processed or shared by Google and its advertising partners as necessary to provide advertising, analytics, fraud prevention, and related services.

Data Security

K Calculator does not maintain a database containing users' personal information.

Data handled by Google's Mobile Ads SDK is subject to Google's security and privacy practices. Google states that data collected by the Mobile Ads SDK is encrypted in transit.

Data Deletion

K Calculator does not provide user accounts and does not maintain a database containing users' personal information. Therefore, the developer does not provide a separate mechanism for users to request deletion of personal information stored by the app.

Data handled by Google AdMob is subject to Google's applicable privacy policies and controls.

Children's Privacy

K Calculator does not knowingly collect personal information directly from children.

If the app is used by children, advertising and data handling are subject to the applicable Google Play and AdMob requirements.
