QUANTUM RINGS TERMS OF USE

Last Updated: October 06, 2025

Effective Date: October 06, 2025

These Terms of Use (“Agreement”) govern your access to and use of the Quantum Rings software development kit (“SDK”), Python library, APIs, simulation services, Open Quantum platform, and related documentation (collectively, the “Services”) provided by Quantum Rings, Inc. (“Quantum Rings,” “we,” or “us”). The Services include quantum circuit execution features, which may involve public or private modes as described below. By creating an account, accessing, or using the Services, you (“Customer,” “you,” or “your”) agree to be bound by this Agreement and our Privacy Policy (available at www.quantumrings.com/privacy), which is incorporated herein by reference. If you are using the Services on behalf of an organization, you represent and warrant that you have authority to bind that organization, and “Customer” will mean both you and that organization.

If you do not agree to these Terms, you may not access or use the Services.

1. Definitions

Authorized Users means individuals who access the Services under your account credentials and associated License Keys.

Customer Data means all information, code, and content that you upload, submit, or process through the Services, including but not limited to quantum circuits and results (subject to our Privacy Policy).

Documentation means written materials and guides provided by Quantum Rings to help you use the Services.

License Key means the alphanumeric key provided by Quantum Rings that enables access to specific tiers or features of the Services.

Usage Data means information we collect about how the Services are used, such as telemetry, performance metrics, or feature utilization. Usage Data does not include Customer Data and is governed by our Privacy Policy.

Intellectual Property Rights means all worldwide intellectual property rights, including but not limited to copyrights, patents, trademarks, trade secrets, and related rights.

Beta Features means any pre-release, experimental, or trial functionality made available by Quantum Rings for testing.

2. Access and Use of the Services

2.1 License Grant. Subject to your compliance with this Agreement, payment of all applicable fees, and agreement to our Privacy Policy, Quantum Rings grants you a limited, non-exclusive, non-transferable, non-sublicensable right to install the SDK, access and use the Services, and apply the corresponding License Key solely for your internal purposes in accordance with this Agreement and the Documentation.

2.2 License Keys. Each License Key is personal to you and may not be shared, transferred, or used by more users than permitted under your subscription tier. You agree not to use unauthorized License Keys or attempt to bypass Quantum Rings’ access control mechanisms. Quantum Rings may revoke or deactivate a License Key if it believes the key has been compromised, misused, or obtained without authorization.

2.3 Restrictions. You may not, and you agree not to allow others to: (a) copy, modify, or create derivative works of the Services; (b) reverse engineer, decompile, or attempt to extract the source code of the Services, except to the limited extent permitted by applicable law; (c) resell, lease, distribute, or otherwise make the Services available to third parties without prior written consent; (d) interfere with or circumvent security or access controls, including License Key restrictions; or (e) use the Services in violation of applicable law or our Privacy Policy.

2.4 Installation and Updates. You are responsible for installing the SDK and ensuring your environment meets the necessary technical requirements. Quantum Rings may provide updates, patches, or new versions of the SDK from time to time, and you agree to install such updates promptly to maintain continued access to the Services.

2.5 Accounts and Credentials. You are responsible for maintaining the confidentiality of your account credentials and for all activities under your account. You must notify Quantum Rings immediately of any unauthorized use or suspected compromise of your account or License Key.

2.6 Usage Data. Quantum Rings may collect and use Usage Data to operate, maintain, improve, and secure the Services, as described in our Privacy Policy. We may also create aggregated and anonymized data sets from Usage Data and use them for research, analytics, and business purposes.

2.7 Beta Features. From time to time, Quantum Rings may make Beta Features available for testing. Beta Features are provided “as-is,” may contain bugs or errors, and may be discontinued at any time. Your use of Beta Features is voluntary and at your own risk.

3. Customer Obligations

3.1 Compliance. You agree to use the Services only in accordance with this Agreement, the Documentation, our Privacy Policy, and all applicable laws and regulations.

3.2 Security. You are responsible for: (a) maintaining the confidentiality of your account credentials and License Keys; (b) ensuring only Authorized Users access the Services; and (c) promptly notifying Quantum Rings if you become aware of unauthorized access or use. Quantum Rings will implement commercially reasonable technical and organizational measures designed to secure the Services against unauthorized access and disclosure.

3.3 Acceptable Use. You may not use the Services to: (a) attempt to interfere with or disrupt the integrity or performance of the Services; (b) gain unauthorized access to Quantum Rings’ systems or networks; (c) upload or transmit malicious code; or (d) engage in any activity that is unlawful, fraudulent, or harmful to others, including but not limited to violations of data protection laws as outlined in our Privacy Policy. When submitting quantum circuits to Open Quantum, you must select the appropriate mode (public or private) based on the confidentiality of your data. Public mode broadcasts circuits to a decentralized network for execution by independent third parties, and you acknowledge that such circuits will not remain confidential. Private mode routes circuits to trusted third-party quantum hardware providers with reasonable measures to maintain privacy.

3.4 Dependencies. You are responsible for obtaining and maintaining any hardware, software, and third-party services needed to install and use the SDK. Quantum Rings is not responsible for failures caused by your environment.

4.1 Free Access. Quantum Rings may provide a free License Key that grants limited access to the Services (“Free Tier”), including basic quantum circuit execution in public mode. Use of the Free Tier remains subject to this Agreement and our Privacy Policy. Quantum Rings reserves the right to modify or discontinue the Free Tier at any time.

4.2 Paid Subscriptions. Certain features or expanded usage of the Services require payment of subscription fees. By purchasing a subscription, you agree to pay the applicable fees displayed at the time of purchase.
