1Who we are
This app, VectraCalc — All-in-One Calculator ("the app", "we", "us"), is published by VectraCalc. This policy explains what information is and isn't collected when you use the app, and your choices. By using the app, you agree to this policy.
2Information the app itself collects
None that identifies you. VectraCalc does not require an account, sign-in, name, email, or phone number to work. Everything you do in the calculators happens on your device.
The following is stored only on your device (in the app's local storage) and is never transmitted to us:
- Your calculation history
- Saved calculations and favorite calculators
- App settings and preferences (theme, decimal places, angle unit, and similar)
You can clear any of this at any time from the app's Settings, and all of it is removed if you uninstall the app.
3Advertising (Google AdMob)
To keep the app free, VectraCalc shows ads using Google AdMob. Serving ads requires an internet connection, and Google (as our advertising partner) may collect and process limited information for this purpose, which can include your device's advertising identifier, general device information, approximate location derived from your IP address, and app-usage signals used to select and measure ads.
We do not receive this advertising data ourselves and do not use it to identify you. Google's handling of it is governed by Google's own policies:
- How Google uses information from apps that use its services: policies.google.com/technologies/partner-sites
- Google Privacy Policy: policies.google.com/privacy
4Purchases (Google Play Billing)
If you buy VectraCalc Pro (Monthly, Yearly, or Lifetime), the purchase is processed entirely by Google Play. We never see or store your payment card details. Google confirms to the app only whether you own a valid purchase, so the app can unlock Pro features.
Your Pro entitlement is tied to your Google account, which is how it restores automatically after you reinstall the app or sign in on another device. Purchases are subject to the Google Play terms and privacy policy.
5Information we do not collect
- We don't collect your name, email, phone number, or contacts.
- We don't collect the values you type into calculators.
- We don't track you across other apps or websites ourselves.
- We don't sell or rent any personal information.
6Children
VectraCalc is a general-audience utility and is not directed at children under 13. We do not knowingly collect personal information from children. If you believe a child has provided information through the advertising or purchase services, please contact us and we'll help direct the request appropriately.
7Your choices & rights
- Ads: reset your advertising ID or opt out of personalized ads in your device settings, or remove ads entirely by upgrading to Pro.
- On-device data: clear history, saved items, and favorites from the app's Settings, or uninstall to remove everything.
- Purchases: manage or cancel subscriptions in Google Play → Payments & subscriptions.
Depending on where you live (for example, under the GDPR or CCPA), you may have additional rights regarding data processed by Google. Please refer to Google's privacy policy linked above, as that data is controlled by Google.
8Data security & retention
Because your app data lives on your device, its security is tied to your device. We recommend keeping your device protected with a screen lock and up-to-date software. On-device data is retained until you clear it or uninstall the app.
9Changes to this policy
We may update this policy as the app evolves or as required by law. When we do, we'll change the "Last updated" date above and post the new version at this page. Significant changes may also be noted in the app or its store listing.
