Terms of Service

Last updated: October 28, 2026

Welcome to MathApex! These Terms of Service (“Terms”) govern your use of the MathApex mobile application. By using our app, you agree to these Terms.

1. Acceptance of Terms

By downloading, installing, or using MathApex, you accept and agree to be bound by these Terms. If you do not agree to these Terms, please do not use the app.

2. Use of the App

MathApex is designed to help children learn mathematics. You agree to:

Use the app only for its intended educational purpose
Not attempt to reverse engineer, decompile, or disassemble the app
Not use the app in any way that violates applicable laws or regulations
Supervise children’s use of the app as appropriate

3. Parental Consent

If you are a parent or guardian, you are responsible for monitoring and supervising your child’s use of MathApex. The parent dashboard provides tools to manage your child’s learning experience.

4. Educational Content

The mathematical content and educational materials in MathApex are provided for informational and educational purposes. While we strive for accuracy, we make no warranties about the completeness or accuracy of the content.

5. Purchases and Subscriptions

The app is free to download. The following optional purchases are available:

MathApex Pro is a one-time purchase.
Apex Pass is valid for one month and does not renew automatically.
Worksheets subscription (“Arbeitsblätter”) is an auto-renewing subscription, available monthly or yearly. It starts with a free trial of 7 days (1 month for owners of MathApex Pro); when the trial ends, it converts to a paid subscription. The subscription renews automatically unless it is cancelled at least 24 hours before the end of the current period. Payment is charged to your Apple account (on Android: your Google Play account). You can manage and cancel the subscription in your store settings: on iOS under Settings › your name › Subscriptions, on Android in the Play Store under Subscriptions. Prices are shown in the store; in Germany, for example, EUR 3.99 per month or EUR 24.99 per year. Only one Worksheets subscription can be active per family at a time; Family Sharing is not supported.

Refunds are handled by Apple or Google under their rules. For purchases through the App Store, Apple’s standard Licensed Application End User License Agreement applies: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/. Purchases and restores require the parent PIN.

6. Worksheet from Photo and Handwriting Recognition

The app can create a worksheet from a photo of a printed sheet (iPhone and iPad) and recognize answers that a child writes with a finger. Both run entirely on the device; no third-party AI service and no cloud service is used, and photos are not uploaded. You retain ownership of the worksheets and custom quizzes you create.

7. Third-Party Services

The app uses the Apple App Store and Google Play for purchases, RevenueCat for purchase and subscription status, and, if a parent switches it on, Apple Game Center (iOS). These services have their own terms of service and privacy policies, which we do not control.

8. Intellectual Property

All content, features, and functionality of MathApex, including but not limited to text, graphics, logos, icons, images, and software, are the property of MathApex and are protected by copyright and other intellectual property laws.
