Terms and conditions
Last updated: 28 October 2026
These terms apply to the Arka Glycan software, licences bought from us, and this website. Arka Glycan is provided by Vaibhav Singh ("we", "us"), Professor Colony, Budaun 243601, Uttar Pradesh, India. By buying a licence or using the software you agree to them.
1. Licence
- A licence lets the licensee use Arka Glycan under the tier and type bought: academic licences for research and teaching at academic or non-profit institutions; industry licences at one site of the licensee's organisation.
- A subscription licence runs for the paid period. A perpetual licence lets you use the versions released during its update period indefinitely.
- A licence key may be activated on the number of computers stated with it. Licence keys are personal to the licensee and may not be shared, sold or published.
- The software is licensed, not sold. You may not copy it for others, remove its notices, or circumvent its licence checks.
2. Trial and beta
The 30-day trial and the beta are provided free of charge and as they are, to evaluate the software. Beta versions may contain errors and may change.
3. Research use
Arka Glycan is a research tool. It is not a medical device and must not be used for diagnosis, treatment or other clinical decisions. Glycan assignments are computational and should be checked by a qualified scientist before you rely on them.
4. Your data
Arka Glycan processes your data on your own computer. We do not receive your spectra or results, and you remain responsible for them. See the privacy policy.
5. Third-party components
Arka Glycan includes open-source components under their own licences, listed with the software. The optional Thermo .raw converter is downloaded from its publisher only after you accept Thermo's licence terms, which then apply to it.
6. Payment, delivery and refunds
Prices are shown on the pricing page; applicable taxes are added. Delivery is digital, as described under shipping and delivery; refunds follow the refund and cancellation policy.
7. Warranty and liability
We will make reasonable efforts to fix reported defects during a paid licence period. Apart from that, and to the extent the law allows, the software is provided without warranties of any kind, and our total liability for any claim relating to it is limited to the amount you paid for the licence in the twelve months before the claim. We are not liable for indirect or consequential losses, including lost data, results or profits.
8. Ending a licence
If you seriously breach these terms, we may end your licence after telling you in writing. You may stop using the software at any time. Your data stay yours in every case.
9. Changes and law
We may update these terms; the version on this page at the time of purchase applies to that purchase. These terms are governed by the laws of India, and the competent courts in India have jurisdiction.
