Terms of Service
The short version
- Curiosand is free. Use it to learn and to teach, and be kind and lawful.
- Simulations are simplified models for learning, not engineering or safety tools, and not a replacement for your teachers or textbooks.
- Accounts are for ages 13+ (under 18 with a parent's or guardian's agreement).
- Please don't copy or resell the site, attack it, or misuse it.
- Indian law applies; you keep any rights your local consumer law gives you.
1. Agreement
These Terms are an agreement between you and [Operator: full legal name of the owner, or registered business name] ("we", "us"), who operates Curiosand (the "Service"), including the website, simulations, quizzes, challenges and related features. By using the Service you agree to these Terms and to our Privacy Policy. If you do not agree, please do not use the Service. If you are under 18, please read these Terms with a parent or guardian.
2. Who can use the Service
- Anyone may use the simulations without an account.
- To create an account or join our mailing list you must be 18 or older, or 13 to 17 with a parent's or guardian's agreement. Children under 13 must not create accounts.
- A parent or guardian who agrees to a child's account accepts these Terms on the child's behalf and is responsible for the child's use of the account.
3. Your account
- Give accurate information, keep your password secret, and tell us at [email protected] if you think someone else has used your account.
- One person per account; accounts may not be sold or transferred.
- You can close your account at any time by emailing us.
4. Free simulations and teacher trials
All simulations, quizzes and challenges are free for everyone, without advertising. Teacher accounts (for adults aged 18 or over) include extra classroom features, such as live quizzes, with a free 15-day trial. The trial needs no payment details, does not turn into a paid plan automatically, and simply ends after 15 days. Teachers are responsible for using live quizzes appropriately with their students, including asking students to use nicknames rather than full names.
We may add optional paid plans for teachers in the future; if we do, we will publish their prices and terms (including a refund policy) before taking any payment, and existing free features will not be removed without notice.
5. Acceptable use
You agree not to:
- break any law, or use the Service to harass, threaten, bully or harm anyone;
- post or send content that is unlawful, obscene, hateful, defamatory, infringing, or harmful to children, or that impersonates someone else (see also Rule 3(1)(b) of India's IT (Intermediary Guidelines and Digital Media Ethics Code) Rules, 2021);
- attempt to break, overload, probe or bypass the security of the Service, or upload malware;
- scrape, copy, mirror, frame or redistribute the Service or its content in bulk, or use it to train AI models, without our written permission;
- use automated tools to create accounts or submit forms;
- remove copyright or other notices.
We may suspend or close accounts, or remove content, that breaks these rules. Where reasonable we will tell you why and give you a chance to respond.
6. Your content
You own the notes, feedback and messages you create ("Your Content"). You give us a non-exclusive, royalty-free licence to store and process Your Content to provide the Service, and to use feedback and suggestions to improve the Service without owing you anything. Please don't include personal information about other people.
7. Our content and your licence to use it
The Service, its simulations, text, graphics, logos and code belong to us or our licensors (see the Intellectual Property Notice). We give you a personal, non-exclusive, non-transferable, revocable licence to use the Service for learning and non-commercial teaching. Teachers may show the Service in class, project it, and share links with students. Anything else, such as republishing, selling or embedding the Service in another product, needs our written permission.
8. Educational content and accuracy
The Service is a learning aid. Simulations use simplified models, rounded constants and sped-up time, and may contain errors. They are not a substitute for teachers, textbooks, official syllabi or laboratory instruction, and must not be relied on for engineering, medical, safety or other real-world decisions. Never attempt a real chemistry or physics experiment based on the Service without proper supervision and safety equipment. See our Educational Disclaimer.
9. Third-party links and services
The Service may link to other websites. We are not responsible for their content or practices.
10. Availability and changes
We work to keep the Service available but cannot guarantee it will always be uninterrupted or error-free. We may change, suspend or discontinue features, and will give reasonable notice of significant changes where we can.
11. Disclaimer of warranties
To the extent permitted by law, the Service is provided "as is" and "as available", without warranties of any kind, express or implied, including fitness for a particular purpose, accuracy and non-infringement. Nothing in these Terms limits any rights you have under consumer protection laws that cannot be excluded, including India's Consumer Protection Act, 2019.
12. Limitation of liability
To the extent permitted by law, we are not liable for indirect, incidental, special or consequential losses, or for loss of data, marks or opportunities, arising from your use of the free Service. Our total liability for any claim relating to the Service is limited to ₹1,000 (or the amount you paid us in the previous 12 months, if higher). Nothing in these Terms excludes liability for fraud, or for death or personal injury caused by negligence, or any other liability that cannot be excluded by law.
13. Responsibility for misuse
If you are an adult and you misuse the Service or break these Terms, you agree to compensate us for reasonable losses and legal costs that result from that misuse.
14. Ending these Terms
You can stop using the Service and close your account at any time. We may suspend or close accounts that seriously or repeatedly break these Terms, or where the law requires. Sections 6, 7, 11, 12, 13 and 16 continue to apply afterwards.
15. Changes to these Terms
We may update these Terms. If a change is significant, we will show a notice on the site and email account holders at least 14 days before it takes effect (unless the change is required by law sooner). If you keep using the Service after that, the new Terms apply; if you don't agree, you can close your account.
16. Governing law and disputes
These Terms are governed by the laws of India. Please contact us first: most problems can be solved quickly through our grievance process. Any dispute that cannot be resolved will be subject to the exclusive jurisdiction of the courts at [City for courts, e.g. Bengaluru], India, except that if you are a consumer living elsewhere, you keep any right to bring proceedings in your local courts and the protection of your local mandatory laws.
17. General
If any part of these Terms is found unenforceable, the rest remains in effect. Our not enforcing a right is not a waiver of it. These Terms, together with the policies they refer to, are the whole agreement between you and us about the Service.
