1. Parties
This Agreement is between you and CQUELLE GmbH only, and not Apple, Inc. ("Apple"). Notwithstanding the foregoing, you acknowledge that Apple and its subsidiaries are third party beneficiaries of this Agreement and Apple has the right to enforce this Agreement against you.

2a. Free use and Flashside Plus
Learning with the App is free of charge. Flashside Plus is an optional auto-renewable subscription sold through Apple's in-app purchase system under the App Store Terms of Service. Apple charges the price shown in the App Store before you confirm, and you manage renewal and cancellation in the subscription settings of your Apple Account. Nothing is charged without your consent. What Plus includes, its fair-use limits and free monthly uses, and the use of AI-generated content are described in section 3 of the Flashside Terms of Service.
3. Limited License
CQUELLE GmbH grants you a limited, non-exclusive, non-transferable, revocable license to use the App for your personal, non-commercial purposes. You may only use the Flashside App on Apple devices that you own or control and as permitted by the App Store Terms of Service.

Your access to the Flashside App may be terminated without warning if CQUELLE GmbH believes, in its sole discretion, that you are under the age of 17 years and have not obtained verifiable consent from a parent or legal guardian. If you are a parent or legal guardian and you provide your consent to your child's use of the Flashside App, you agree to be bound by this Agreement in respect to your child's use of the App.
