Terms of Service

CubeSolver AI · Effective 2026-05-01

These Terms of Service (the “Terms”) govern your use of the iOS application CubeSolver AI (the “App”), operated by Ganzhou Xiaomai Information Technology Co., Ltd. (“we”, “us”, “our”). By downloading, installing, or using the App you agree to these Terms. If you do not agree, do not use the App.

1. Description of Service

CubeSolver AI is an iOS mobile app that lets users scan a Rubik’s Cube using the device camera and obtain step-by-step solving instructions. Some features (extended formula library, advanced solving modes) are gated behind an auto-renewing subscription described below.

2. License Grant

Subject to your compliance with these Terms, we grant you a limited, non-exclusive, non-transferable, revocable license to download and use the App on Apple-branded devices that you own or control, solely for your personal, non-commercial use.

3. Acceptable Use

You agree not to:

• Reverse-engineer, decompile, or attempt to extract source code from the App, except as expressly permitted by applicable law;
• Modify, adapt, or create derivative works of the App;
• Remove or obscure any proprietary notices on the App or related materials;
• Use the App to violate any law, infringe any rights of others, or transmit malicious code;
• Interfere with the App’s normal operation or attempt to gain unauthorized access to our backend systems.

4. Subscription Plans

The App offers paid auto-renewing subscriptions sold exclusively through Apple’s In-App Purchase system. Localized prices displayed at the point of purchase are determined by Apple StoreKit based on your Apple ID country or region; the reference USD prices below are indicative and may differ in your local currency.

5. Billing and Auto-Renewal

• Payment on purchase. Payment is charged to your Apple ID account at confirmation of purchase.
• Automatic renewal. Your subscription automatically renews for the same duration at the then-current price unless auto-renewal is turned off at least 24 hours before the end of the current period.
• Renewal charge timing. Your Apple ID is charged for the renewal within 24 hours prior to the end of the current period.
• No mid-period cancellation. Once a subscription period has been paid for, it cannot be cancelled for the remainder of that active period.
• Price changes. We may change prices from time to time. Apple will notify you and obtain your explicit consent before any increased price takes effect.

6. Free Trial

The Weekly plan includes a 3-day free trial for first-time subscribers. Auto-renewal at the regular Weekly price begins immediately when the trial ends. The Yearly plan does not include a free trial.

Turning off auto-renewal during the free trial will end the trial at its scheduled end date and no charge will be made. Any unused portion of the trial period will be forfeited if you upgrade or change plans during the trial.

7. Managing and Cancelling Your Subscription

Subscriptions are billed and managed through your Apple ID. You can cancel at any time before the next renewal date to prevent further charges. The steps below are provided by Apple and take less than a minute.
