Terms of Service

These Terms of Service (“Terms”) apply when you use StudyFlow, which is operated by 21st Century Network Technology Service Studio (“we”, “us”). By using StudyFlow, you agree to these Terms. If you don’t agree, please don’t use the service. How we handle personal information is described in our Privacy Policy.

1. The service

StudyFlow is an AI study assistant. It imports your documents and web pages, turns them into study cards, creates practice questions, checks your answers and suggests when to review and what to learn next.

2. Who can use StudyFlow

You must be at least 13 years old to use StudyFlow. If you are under 18, or under the age of majority where you live, you need permission from a parent or guardian, who accepts these Terms on your behalf.

3. Your account

Keep your login details secure and tell us right away if you think someone else has used your account. You are responsible for activity under your account.

4. Plans and payment

Paid plans are billed monthly in US dollars at the price shown on our website when you subscribe, and renew each month until you cancel. Taxes may be added depending on where you live. If we change the price of your plan, we will tell you at least 30 days before the new price applies. Refunds and cancellations are covered by our Refund Policy.

5. Your content

You keep all rights to the materials you import and to the cards and notes created from them. You allow us to store and process your materials only as needed to provide StudyFlow to you. You must have the right to use everything you import.

6. Acceptable use

When you use StudyFlow, you agree not to:

• import files or web pages you don’t have the right to access or use;
• bypass logins, paywalls or other access controls when you import a web page;
• use StudyFlow to break the law, infringe anyone’s rights or share content you are not allowed to share;
• disrupt or overload the service, or try to access it in ways we don’t allow;
• share your account or resell access to it.

Importing content into StudyFlow doesn’t give you any extra right to copy or share it.

7. AI-generated content

Summaries, cards, questions, answers and suggestions are generated by AI and can be incomplete or wrong. Check important information against your original materials. StudyFlow is a study aid and doesn’t guarantee any particular grade, exam result or learning outcome. You can change or ignore any review plan or suggestion.

8. Our intellectual property

StudyFlow, including its software, design and name, belongs to us. These Terms let you use the service but don’t give you any other rights to it.

9. Changes to the service

We work to keep StudyFlow available and reliable, but we can’t promise that it will always be available or free of errors. We may add, change or remove features. If a change significantly reduces what your paid plan includes, we will tell you in advance.

10. Suspension and termination

You can stop using StudyFlow and cancel your plan at any time. We may suspend or close your account if you seriously or repeatedly break these Terms, or if the law requires us to. Where possible, we will tell you first and give you a chance to export your materials.

11. Disclaimer

StudyFlow is provided “as is” and “as available”. To the extent the law allows, we make no other promises about the service, including that it is suitable for a particular purpose.

12. Limitation of liability

To the extent the law allows, we are not liable for indirect or consequential losses, such as lost data, profits or opportunities. Our total liability for any claim related to StudyFlow is limited to the amount you paid us in the 12 months before the claim. Nothing in these Terms limits liability that cannot be limited by law.

13. Governing law and disputes

These Terms are governed by the laws of the People’s Republic of China, excluding the laws of Hong Kong, Macao and Taiwan. If a dispute arises, please contact us first so we can try to resolve it together. If we can’t resolve it within 30 days, either side may take it to the competent court where we are located. This doesn’t affect any mandatory consumer rights you have under the law of the country where you live.

14. Changes to these Terms

If we update these Terms, we will change the “Last updated” date at the top. If the changes are significant, we will also tell you by email or on our website before they take effect. If you keep using StudyFlow after that, the updated Terms apply.
