PRIVACY AND ADS
No account is required. Expressions, calculation history, and preferences stay on your device. The date of birth entered on first launch is used only in memory to derive an age group, then discarded without being stored or transmitted. Only the derived group stays on the device, and that local value itself is not sent to Google; child-directed-treatment and under-age-of-consent advertising booleans derived from it are sent to Google. Every age group gets the same features. The first launch is ad-free. Starting with the second launch, a Google AdMob banner may appear at the bottom of the calculator. Requests for users age 17 or under, or whose age is unknown, are non-personalized, G-rated, Families-compliant, and do not transmit the advertising ID. Adult ads also have a maximum G rating and apply regional privacy choices. See the Privacy Policy for details.

Whether you are studying math, science, or engineering, NumiGraph keeps the calculation and graph tools you need close at hand.
