None that identifies you. Everything you enter into a calculator — loads, wire sizes, bends, meter readings, and so on — is processed on your device and is never sent to us or to anyone else. Your app settings (such as theme and any saved preferences) are stored locally on your device only.
The free version of Voltbox shows a single banner advertisement through Google AdMob. To serve ads, Google may collect and process certain information, which can include your device's advertising identifier, general (non-precise) location inferred from your IP address, device and app information, and ad-interaction data. Google uses this to deliver and measure ads and, where applicable, to serve personalized ads.
Where required by law (for example, under the GDPR), Voltbox uses Google's User Messaging Platform (UMP) to present a consent form the first time you open the app. Your choice determines whether personalized ads are shown. You can change your choice at any time from within the app's consent options.
Voltbox offers a one-time in-app purchase, Voltbox Pro. Payments are processed entirely by Google Play; we never see or receive your payment card, billing address, or other financial details. Google provides us only with the anonymous entitlement status needed to unlock Pro features and to verify or restore your purchase. Google's processing of your payment is governed by the Google Privacy Policy.
Voltbox requests Internet access, which is used only to load ads and to process purchases through the services above. The app does not request access to your contacts, camera, microphone, precise location, files, or other sensitive device data.
We do not sell your personal information. We do not share personal information with third parties except as necessary for the advertising and billing services described above, each acting under its own privacy policy.
Because the app stores your data only on your device, uninstalling Voltbox removes that data. Advertising and purchase data held by Google are retained and deleted according to Google's policies. To request information about data associated with your Google advertising identifier, use your device's Google settings.
Voltbox is a professional trade tool intended for a general audience of electricians, apprentices, and adult hobbyists. It is not directed to children under 13, and we do not knowingly collect personal information from children.
We may update this policy from time to time. Material changes will be reflected by the "Last updated" date above and, where appropriate, noted in the app's release notes.
