Terms of sale and use

Last updated: 6 November 2026

1. Who we are

VivaKit are sold by Vishwanath Reddy B, trading as VivaKit, India ("we", "us"). Contact: [email protected]. Payments are processed by our payment partner; we never see your card or UPI details.

2. What you buy

A digital download ("kit") containing source code, a demo application, trained model weights, reference results, a learning guide, a setup script, tests and a dataset download script. Datasets are not included; the kit downloads them from their original public sources under their own licences (CC BY 4.0).

3. Licence

• One purchase covers one academic project team of up to four students at the same institution.
• You may use, study and modify the kit and submit it as part of your own academic project.
• You may not resell, share, upload or publish the kit or substantial unmodified parts of it, or use it to provide paid project services to others.
• The full licence text is in LICENSE.txt inside each kit and prevails over this summary.
• Every copy is personalised: it carries the buyer's name, e-mail, order number and a unique fingerprint, so copies shared or resold in breach of the licence can be traced to the order. A licence breached this way ends immediately, without refund, and we may request removal of shared copies from any website, group or channel.

4. Academic integrity

Kits are learning material. We do not write project reports, theses, synopses, presentations or assignments, and we do not provide plagiarism-evasion services. You are responsible for following your institution's rules, acknowledging the kit and citing the datasets, and for writing your own report about your own work.

5. Not a medical device

The kits and their models are for education only. They are not intended for diagnosis, treatment or any clinical decision-making and must not be used on real patients.

6. Results and compatibility

Metrics shown on this website were measured on our own computer (Windows 11, NVIDIA RTX 5070 Laptop GPU) on the held-out test splits described in each kit. Your results may differ slightly. Supported platform: Windows 10/11 64-bit with Python 3.10-3.12. We do not guarantee any grade or academic outcome.

7. Support

We help by e-mail with installation problems on supported systems. The learning guide in each kit explains the concepts, the code and how to plan your extension.

8. Refunds

See the refund policy.

9. No warranty and limitation of liability

Kits are provided "as is", without warranty of any kind. To the maximum extent permitted by law, our total liability is limited to the amount you paid for the product concerned.

10. Governing law

These terms are governed by the laws of India.
