Terms & Conditions
Last updated 15 October 2026
These Terms govern your use of Viditra (“the Service”), a software product that gives teachers interactive, accurate simulations to teach with in class. By creating an account or using the Service, you agree to these Terms.
1. The Service
Viditra provides a library of interactive simulations for Class 11–12 physics, chemistry and mathematics, built on India’s NCERT syllabus, and a live teaching surface for teachers. New simulations and features are added regularly. The Service is provided on an “as is” and “as available” basis.
2. Your account
You are responsible for keeping your login credentials secure and for all activity under your account. The Service is intended for teachers and educators. One account is for one teacher; please do not share your login. Notify us promptly of any unauthorised use.
3. Free access, plans & billing
- Every teacher can use the Service free until 31 March 2027, with no card required. You will never be charged automatically: if we introduce a paid plan for individual teachers after that date, we will tell you by email before it starts, and you pay only if you choose it.
- Schools, institutes and colleges are quoted per campus — those terms are set out in the written agreement for that institution.
- Paid subscriptions taken out before free access began remain valid at their locked rate for as long as they stay active.
- Payments are processed securely by our payment partner, Razorpay. A paid subscription continues month to month until you cancel.
- Cancellation and refunds are covered in our Refund & Cancellation Policy.
4. Acceptable use
You may use the simulations for teaching your own students — in your classroom, online, or on a projector. You may not resell, redistribute, scrape, copy, or reverse-engineer the simulations or any part of the Service, or use it in a way that infringes the rights of others or breaks the law.
Publishing the simulations in public content (YouTube, social media, recorded courses) requires a separate content licence — contact us. We grant these; we just need to agree the terms first, including how Viditra is credited.
5. Intellectual property
All simulations, content, designs, and software in the Service are owned by Viditra. While your account is active, you have a limited, non-exclusive, non-transferable licence to use them for teaching your own classes. This licence ends when your access ends.
6. Disclaimer & limitation of liability
Viditra is a teaching aid. While we work hard to keep the physics accurate, we do not warrant that the Service will be uninterrupted or error-free, or fit for a particular purpose. To the fullest extent permitted by law, our total liability to you is limited to the fees you paid us in the month before the claim arose.
7. Changes
We may update the Service and these Terms from time to time. If we make a material change, we will notify you by email. Continued use after a change means you accept the updated Terms.
8. Governing law
These Terms are governed by the laws of India, and any disputes are subject to the courts of Telangana, India.
