These Terms of Use ("Terms") constitute a legally binding End User License Agreement ("EULA") between you and Product Craft LLC ("Mustr," "we," "us," or "our") governing your use of the Mustr mobile application ("App") and related services (collectively, the "Service"). By downloading, installing, or using the App, you agree to these Terms.

Mustr helps organizers fill games or events by managing invitations to regular participants and substitutes.

2. License Grant

Subject to your compliance with these Terms, Mustr grants you a limited, non-exclusive, non-transferable, revocable license to download, install, and use the App on any mobile device that you own or control, solely for your personal, non-commercial purposes.

You may not: (a) copy, modify, or distribute the App; (b) reverse engineer, decompile, or disassemble the App except to the extent permitted by applicable law; (c) rent, lease, lend, sell, or sublicense the App; or (d) use the App to create a competing product or service.

The App is licensed, not sold, to you. Mustr reserves all rights not expressly granted in these Terms.

4. Accounts

You are responsible for providing accurate information, maintaining the confidentiality of your account credentials, and all activity under your account.

Some features require a paid subscription. Free trial periods may be offered. Unless you cancel before the trial period ends, your subscription will automatically convert to a paid subscription at the then-current rate.

Auto-Renewal: Subscriptions automatically renew at the end of each billing period (monthly or annually, depending on your plan) unless you cancel at least 24 hours before the end of the current period. Your account will be charged for renewal within 24 hours prior to the end of the current period at the then-current subscription rate.

How to Cancel:

Payment Processing: All payments are processed by the Apple App Store or Google Play, depending on your device. Payment is charged to your App Store or Google Play account at confirmation of purchase. Mustr does not directly collect or store your payment information. Refund requests should be directed to the applicable app store per their policies.

You retain ownership of your User Content, but you grant Mustr a non-exclusive, royalty-free license to use it solely to operate, maintain, and improve the Service.

We may update these Terms from time to time. For material changes-such as modifications to data collection practices, subscription pricing, dispute resolution terms, or user rights-we will notify you via email or in-app notification at least 14 days before the changes take effect. Continued use of the Service after such notice constitutes acceptance of the updated Terms.
