MultiCalc AI — Privacy Policy

Last updated: October 15, 2026

MultiCalc AI ("we", "our", or "us"), a product of ZuTech Apps, is committed to protecting your privacy. This Privacy Policy explains how our mobile application handles your information. By using MultiCalc AI, you agree to this policy.

1. Introduction

MultiCalc AI is an all-in-one calculator app — everyday math, financial, unit conversion, education, and home/construction calculators, plus calculators you build yourself. It's designed to work entirely on your device. We do not require you to create an account, and we do not collect personally identifiable information (PII).

2. Information We Process

• Your calculations and settings: Calculation history, favorites, app preferences, and any custom calculators you create are stored locally on your device only, using standard Android app storage. We never receive or see this data.
• Optional AI features: MultiCalc AI includes optional features — explaining a result in plain language, drafting a custom calculator from a description, or answering a quick plain-language question — that are turned off by default. If enabled in a future update, the specific text you type for that feature is sent to our server and relayed to a third-party AI provider solely to generate that response. No other app data is included, and the numeric result shown to you always comes from the app's own built-in calculation logic, never from the AI.

3. Third-Party Services

MultiCalc AI integrates the following service to support core features:

• Google AdMob: Used to display advertisements (banner, interstitial, and native ad formats). AdMob collects standard device advertising identifiers (such as Android AAID) and general device/usage signals to deliver ads in compliance with Google policies. Where required, you'll be shown a consent prompt before any personalized advertising is enabled. See Google's Privacy Policy and how Google uses AdMob data.

4. What We Don't Do

• We don't require sign-in or collect your name, email, or account information.
• We don't sell your information — we don't have any of it to sell.
• We don't collect financial account numbers, health information, or government IDs.

5. Children's Privacy

MultiCalc AI does not knowingly collect data from children under the age of 13. The app is rated for general audiences and contains no content inappropriate for children.

6. Changes to This Policy

We may update this Privacy Policy from time to time. We will notify users of changes by updating the date at the top of this page. Continued use of the app after updates constitutes acceptance of the new terms.
