FAQ
Frequently asked questions.
About the studio, our apps, and how we work. Looking for questions about the calculator itself? See the app FAQ.
What is VectraCalc?
VectraCalc is an independent app studio. We build focused, offline-first tools that respect your privacy — starting with VectraCalc: All-in-One Calculator for Android: 209 calculators with step-by-step solutions, interactive graphs and 3D.
What apps do you make?
Right now, one: the All-in-One Calculator, coming soon to Google Play. More apps are in the works — follow us on Instagram or X for announcements.
Which platforms do you support?
Our apps currently target Android, distributed through Google Play. Other platforms may follow as the studio grows.
Do your apps really work offline?
Yes — offline-first is our core principle. Every feature works with no connection, no account, and no sign-in. Nothing you enter ever leaves your device.
How do you handle privacy?
We collect no personal data ourselves. Free apps show ads via Google AdMob, and purchases go through Google Play — each app's privacy policy explains exactly what those Google services collect. See the calculator's privacy policy and data deletion page.
Are your apps free?
Yes — free to download and use, supported by ads. An optional Pro upgrade removes ads and unlocks premium features like unlimited step-by-step solutions and graphing.
How do I get support or report a bug?
Use the contact form or email vectracalc@gmail.com. Including your device model and Android version helps us fix issues faster.
Can I suggest a feature or a new app idea?
Please do! Some of our best improvements come from user suggestions. Send ideas through the contact form — pick "Feature idea" as the topic.
