Privacy Policy

Last updated 26 August 2026

Genzmath has no account, no profile and no analytics. Your history stays on your iPhone. To write an answer, the two words you enter are sent to our answer service and passed to an AI model — and then discarded.

What the app stores on your device

• Your calculations: the words you enter, the results, and anything you mark as a favourite. Saved locally so your history is there when you come back.
• Nothing else. No name, no email, no contacts, photos, location, or device identifiers.

What we collect

There is no account to create, and the app contains no analytics, no crash reporting, no advertising and no attribution software. We do not ask for your name or email, and we do not receive any device or advertising identifier.

The one thing that does leave your iPhone is the pair of words you ask Genzmath to calculate, and only at the moment you press Calculate. We do not write them to a database or a log file, and because nothing identifying travels with them, we could not attribute them to you even if we kept them.

How results are generated

Genzmath has three ways of writing an answer, and it uses the first one available:

• Our answer service. The two words and the operation you chose are sent over an encrypted connection to a service we run, which checks them against a safety filter and asks an AI model from OpenAI to write the phrase and its explanation. OpenAI processes the words to generate that reply. Neither we nor OpenAI receive your name, email, account or device identifier, because the app has none to send. To confirm that you are a subscriber, the app sends the receipt Apple issued for your subscription; it proves a subscription is active and says nothing about who you are.
• Apple Intelligence. On iPhones that support it, the answer can instead be written by Apple's on-device language model. Nothing is sent anywhere in this case.
• The built-in engine. With no connection, answers come from a lexicon compiled into the app. Nothing is sent anywhere in this case either.

Your saved history, your favourites and everything the app has already produced stay on your iPhone throughout. They are never uploaded, under any of the three.

Reporting an answer

If an answer is inappropriate, the app can open a pre-filled email so you can tell us. Nothing is sent unless you press send in your own mail app, and what you send is an ordinary email that we read like any other.

Subscriptions and payment

Subscriptions are purchased and managed through Apple. Payment is handled entirely by Apple and we never see your card details, billing address, or any payment information. We receive only the aggregate, anonymous sales reporting that Apple provides to developers, which cannot be traced back to an individual.

Deleting your information

Clearing your history in the app removes it. Deleting the app removes everything the app has stored. That is the whole of it: your history never leaves your iPhone, we do not store the words sent to the answer service, and there is no account to close.

Deleting the app does not cancel a subscription. Subscriptions are managed by Apple and can be cancelled at any time in Settings → your Apple Account → Subscriptions.

Children

Genzmath is intended for a general audience and is not directed at children. Because we collect no personal information at all, we do not knowingly collect personal information from children.

Changes to this policy

If this policy changes, the revised version will be published here with a new date at the top.
