Terms of Service

MagicGourd is provided by DeepFlywheel Hong Kong Limited (“we”), helping you save, annotate, and organize reading materials, and use AI to assist with understanding and writing. These Terms explain your rights and responsibilities and ours when you use the browser extension and official website. For questions or requests, please contact support@deepflywheel.com.

Using the Service

Please accept these Terms before using the service; if you do not agree, please stop using it. If you have not reached the legal age to enter into contracts independently where you live, please use the service with your guardian's consent and guidance.

Please provide valid account information, safeguard your email account, verification codes, and sign-in credentials, and do not impersonate others. If you discover unauthorized use of your account, please contact us promptly. You are responsible for your own use of the service; losses caused by us will be handled under applicable law.

Your Content

Your rights to your original notes and other content you own remain unchanged. Rights to third-party materials, such as source webpages, documents, and images, remain with their respective rights holders; saving, highlighting, or using AI does not change those rights. Please ensure you have the right to use materials in the relevant manner, and comply with applicable law and third-party rights when exporting or sharing them with others.

You authorize us and the service providers we engage to store, copy, transmit, and process relevant content only as necessary to provide the features you request. This authorization does not transfer ownership of the content or permit us to use it separately for advertising, public distribution, or model training. The authorization is valid only within the scope and for the period needed to provide the relevant features; the Privacy Policy explains deletion and legally required retention.

Our software, brand, and the website's own content are protected by intellectual property rights; these Terms grant you only the right to use the service as agreed. See the Privacy Policy for how we handle your personal information and content.

AI Features

AI answers, enhanced notes, and citations may contain errors, omissions, or outdated information. Please check the source materials before using them. For important judgments involving matters such as health, law, or finances, please seek appropriate professional advice.

You may use AI outputs subject to applicable law and third-party rights; we do not claim ownership of those outputs from you merely because we provide the service. We do not guarantee that outputs are unique, necessarily protected by copyright, or free of third-party rights.

Acceptable Use

Do not use the service to engage in unlawful conduct, infringe others' rights, upload malicious software, access accounts or data without authorization, disrupt the service, or bypass access or usage limits. Do not crack, copy, or distribute our software except as permitted by law.

If you discover suspected infringement or abuse, you may provide us with the relevant details and supporting evidence. We will address the matter according to applicable law and the circumstances, and take proportionate restrictive measures.

Fees and Subscriptions

Before you use paid features, we will show you the price, service period, feature scope, and applicable renewal, cancellation, and refund rules. Please confirm this information before purchasing; browsing pricing or clicking subscribe does not grant paid access without a completed purchase.

Automatic renewal must be clearly disclosed at purchase; you may cancel future renewals, and cancellation should be as easy as subscribing. Canceling renewal and refunding fees already paid are separate matters. Refunds are handled under the rules disclosed at purchase and applicable law.

We will give advance notice of material changes to prices or paid benefits, and will not retroactively change the agreed terms for a service period already purchased. These Terms and the terms on the purchase page do not exclude your statutory consumer rights.

Service Changes and Termination

We may update features or perform maintenance, and do not guarantee uninterrupted service or compatibility with every webpage. Where reasonably practicable, we will give advance notice of material changes affecting purchased benefits or the availability of your materials.

You may stop using the service, export content, or delete your account in settings. Account deletion is irreversible; account and content deletion are handled under the Privacy Policy. If you have a subscription, please also cancel its renewal.

We may restrict or terminate the service for serious violations of these Terms, unlawful conduct, or security risks. Unless prohibited by law or immediate action is needed, we will explain the reason and provide a contact channel. If we discontinue operations in the ordinary course, we will give advance notice and a reasonable opportunity to export content before closure; unfulfilled paid services will be handled under applicable law and the purchase terms.

Service Responsibilities

We will take reasonable measures to maintain the service's security and availability, and make efforts to fix failures and reduce their impact. Please keep backups of important content; this recommendation does not relieve us of our legal responsibilities.

If events such as force majeure prevent performance of the service, the parties' responsibilities will be determined by law, and we will still take reasonable measures to mitigate the impact. These Terms do not exclude or limit liability that cannot legally be excluded or limited.

Changes to These Terms and Disputes

We will notify you of material changes to these Terms through in-product notices, email, or website announcements, and state when they take effect; we will obtain your consent again where required by law. If you do not agree to a change, you may stop using the service; purchased benefits will be handled under the purchase terms and applicable law.

These Terms are governed by the laws of the Hong Kong Special Administrative Region, without excluding consumer protections that cannot legally be excluded where you live. If a dispute arises, please first contact us at support@deepflywheel.com to seek a resolution; if no agreement is reached, you may seek resolution in a court with lawful jurisdiction. The invalidity of an individual provision does not affect the validity of the other provisions.
