Privacy Policy

Draft — last updated 2026-09-13. This has not yet had formal legal review.

This page describes, in plain language, what NoMathix CalculatAll and CalculatAll Free actually collect and why, based on a direct review of the apps' code. It is written to be accurate, not aspirational — but it is still a draft and should get a legal review pass before being treated as your final, binding policy.

NoMathix CalculatAll and CalculatAll Free ("the app," "we," "us") are operated by Nomatic Studios. This policy covers both versions and explains what information each collects, why, and how you can control it.

There's no account, and nothing is uploaded

Neither version asks you to sign up or sign in. Your calculation history, saved Y= functions, matrices, custom color theme, and any saved polygon cut lists are all stored locally on your device using Apple's on-device storage — none of it is ever sent to us or to anyone else. Uninstalling the app removes all of it. We have no way to see your data, because it never leaves your device.

Advertising (CalculatAll Free only)

CalculatAll Free is supported by ads served through Google's AdMob platform. AdMob may use your device's advertising identifier to serve and measure ads. The first time you open CalculatAll Free, iOS will ask for your permission (App Tracking Transparency) before that identifier is used for personalized ads — if you decline, you'll still see ads, just not personalized ones. NoMathix CalculatAll (the paid version) shows no ads and uses no advertising SDK at all.

What we don't collect

Neither version accesses your location, contacts, photos, camera, or microphone, and neither includes any analytics or crash-reporting SDK. We don't know how often you use the app, what you calculate, or anything else about your usage.

Who we share information with

We don't sell any information, because we don't collect any to sell. The only third party involved is:

Google AdMob — serves and measures ads in CalculatAll Free only.

Your choices

Uninstall the app to remove all locally-stored data.
Decline the App Tracking Transparency prompt in CalculatAll Free to limit ad personalization.
Switch to NoMathix CalculatAll if you'd rather not see ads at all.

Children's privacy

The app doesn't knowingly collect information from anyone, of any age, since there's no account and nothing is transmitted off your device.

Changes to this policy

If this policy changes in a meaningful way, we'll update the date at the top of this page.
