Privacy Policy

Effective Date: August 22, 2026

This Privacy Policy explains how VoltCalc ("VoltCalc", "we", "us", or "our") handles information when you use the VoltCalc Android application.

1. Information We Collect

VoltCalc does not directly collect personal information such as your name, email address, phone number, home address, contacts, photographs, microphone recordings, or precise location.

VoltCalc does not require you to create an account or register with us.

VoltCalc's core calculation functionality is designed to operate offline. Calculation inputs, saved projects, and calculation history may be stored locally on your device so that the application can provide its features.

We do not use those locally stored calculations to build a personal profile about you or sell your information to third parties.

2. Information Stored on Your Device

Depending on the features you use, VoltCalc may store information locally on your Android device, including:

• Saved calculation inputs and results
• Saved project names and project-related calculation information
• Application preferences and settings
• Calculation history

This information is used solely to provide the application's features. VoltCalc does not transmit this locally stored information to its own servers.

3. Advertising

VoltCalc uses Google AdMob to display advertisements to users of the free version of the application.

AdMob is a third-party advertising service operated by Google. Google may process information such as device identifiers, IP address, approximate location, advertising-related identifiers, and information related to ad requests, delivery, measurement, and personalization, subject to Google's policies and the settings applicable to your region and device.

VoltCalc does not directly receive or store your personal advertising profile from Google.

More information is available in Google's documentation:

4. Advertising Consent and Regional Privacy Choices

Depending on your location, Google may request consent or provide privacy choices before personalized advertising is shown.

For users in regions covered by applicable privacy regulations, VoltCalc may use Google's consent-management mechanisms to present relevant choices regarding advertising and related data processing.

5. Google Play Billing

VoltCalc offers a one-time lifetime purchase through Google Play Billing. This purchase unlocks the applicable premium features of the application.

Payments are processed through Google Play. VoltCalc does not receive or store your credit card number, debit card number, bank account information, or other payment credentials used to complete a Google Play purchase.

Google may process purchase-related information as necessary to complete, verify, restore, and manage your purchase.

6. Third-Party Services

VoltCalc currently uses the following third-party services:

• Google AdMob — advertising and ad measurement
• Google Play Billing — processing of in-app purchases

These services are operated by Google and may process information according to Google's policies.

VoltCalc does not sell your personal information to advertisers, data brokers, or other third parties.

7. Data Sharing

VoltCalc does not operate a personal-data database or sell personal information to third parties.

However, third-party services integrated into the application, such as Google AdMob and Google Play Billing, may independently process information required to provide advertising, measurement, payment, fraud prevention, and related services.

8. Data Security

Because VoltCalc does not operate a backend account system for its core features, most calculation information remains on your device.

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

9. Children's Privacy

VoltCalc is a professional electrical calculation utility and is not specifically directed toward children.

We do not knowingly collect personal information directly from children.

10. Your Choices

You can choose whether to use VoltCalc's premium lifetime purchase. Purchasing premium features is optional.

You can also manage certain advertising and privacy choices through Google's available settings and consent mechanisms.

You may remove locally stored VoltCalc information by deleting the application's local data or uninstalling the application, subject to Android's system behavior and any information separately maintained by Google for advertising or purchase purposes.

11. Changes to This Privacy Policy

We may update this Privacy Policy from time to time to reflect changes in VoltCalc, applicable law, or the third-party services used by the app.

When changes are made, the updated policy will be published at the same privacy-policy URL and the effective date will be updated.

13. Governing Principles

VoltCalc is designed with a privacy-minimizing approach. The application does not require an online account for its core calculation features and does not operate a backend system intended to collect or profile users.

Third-party services integrated into the application remain subject to their own privacy policies and terms.
