Terms of Service

Effective 2026

These terms govern your use of Diomgis at diomgis.com and in the Diomgis app (together, the "Platform"), and every course, programme or other service you use or buy through it, including mentoring. The Platform is owned and operated by Sigmoid Vedanta Technologies ("we", "us"), a micro enterprise registered in Kerala, India (Udyam UDYAM-KL-12-XXXXXXX), 5/2197, CHERUVICKAL, SREEKARYAM - 695017. By creating an account or buying a service you agree to these terms. If you do not agree, please do not use the Platform.

1. Accounts and eligibility

You must be 18 or older to create an account. You agree to give accurate details, keep your password private, and use the account yourself; accounts may not be shared. You are responsible for activity under your account and should tell us at once if you suspect misuse. You can delete your account at any time from your account page.

2. What we provide

The Platform offers live online courses taught in cohorts, programmes made up of several courses, mentoring by screened practitioners (open to every member; each mentor sets their own price per session, and some offer sessions with no payment), learning materials (lesson notes, labs, quizzes, flashcards and similar) and AI-assisted learning tools. Each course page states its learning outcomes, workload, schedule and assessment, and each cohort open for enrolment states its fee. You pay for a seat in a course cohort, or for a mentoring session at the price the mentor sets; there are no memberships or subscriptions. We may improve or change the Platform, but we will not materially reduce a course you have already paid for.

3. Prices, payment and enrolment

  • Prices are shown in Indian rupees on the pricing page and on each course page, and include applicable taxes unless stated otherwise. The price you pay is the one shown at checkout.
  • Payments are processed by Razorpay Software Private Limited. We never see or store your full card number, UPI PIN or banking password.
  • Your enrolment is confirmed when payment succeeds and we send a confirmation email. If money leaves your account but the payment fails, the payment provider normally reverses it automatically within 5 to 7 working days; contact us if it does not.
  • The amount for a mentoring session is set by the mentor and shown to you before you pay. When you pay for a mentoring session through the Platform, we collect the payment on the mentor's behalf, and the session is confirmed when the mentor confirms it, as section 6 describes.
  • We may change prices for future purchases. A change never affects a purchase you have already completed.
  • If a price is shown in obvious error, we may cancel the order and refund you in full.

4. No subscriptions

We do not sell subscriptions, memberships or credit packs, and nothing renews or is charged again automatically. Each payment is a one-time payment for a seat in a course cohort or for one mentoring session. If we ever offer a subscription, we will update these terms before it goes on sale.

5. Live sessions and schedules

  • Courses are delivered online through video-conferencing services such as Zoom or Google Meet, and community channels such as Discord. You need a suitable device and internet connection.
  • The cohort schedule is published before the cohort starts. Session times are set in Indian Standard Time and shown in your chosen time zone.
  • If we have to cancel or move a session, we will give as much notice as we can and either reschedule it or make a recording available. If we cancel a cohort or delay its start by more than 14 days, you may choose a full refund or a place in another cohort.
  • Group sessions may be recorded and shared only with your cohort. If you do not want to appear in a recording, keep your camera and microphone off and use the chat. You must not record sessions yourself.

6. Mentors and mentoring

Mentors are experienced practitioners whose applications we have screened and approved. Any member can ask a mentor for mentoring through the Platform, with or without a course seat, and the mentor decides whether to accept. A mentor who accepts schedules sessions on the Platform. Sessions take place on a video service the mentor chooses, such as Google Meet, Zoom or Microsoft Teams, through the link they give you; that service's own terms and privacy policy apply to the call. Mentoring sessions are not recorded unless both you and the mentor agree.

  • Prices: each mentor sets their own price per session, and some offer sessions with no payment. When a mentor schedules a session, they can change its amount or set it to nothing to pay. You see the amount before you pay.
  • Paying through Diomgis: if the mentor accepts payments through the Platform, you pay on the Diomgis website by card, UPI, net banking or wallet, through Razorpay. We collect the payment on the mentor's behalf and take no commission. The mentor receives the amount less Razorpay's fee on that payment (as Razorpay reports it, including GST), which we tell the mentor up front. We record what we owe each mentor and pay it by bank transfer or UPI.
  • Paying the mentor directly: if the mentor accepts direct payments, you pay them using the payment instructions they give, such as a UPI ID, payee name or payment link, which you see while a session is awaiting your payment. You then mark the session as paid on the Platform, with the payment reference and, if you like, a screenshot or PDF as proof. The mentor confirms the payment, or rejects it with a reason; if they reject it, you can send it again. A direct payment is between you and the mentor: we do not hold, handle or refund it. If a mentor asks you for a payment that is not for a session scheduled on the Platform, please tell us through the contact form.
  • Confirmation: a session with an amount to pay is awaiting payment until you pay and the mentor confirms it. Until then, either of you can propose a different time or cancel it on the Platform. A session with no payment is scheduled straight away, and either of you can propose a different time or cancel it. Payment deadline: the mentor sets how long before a session payment is due (6, 12, 24, 48 or 72 hours; 24 unless they choose otherwise), and you see the exact deadline in your own time zone. A session scheduled closer to its start than that is due as soon as possible: one hour after it is scheduled, and never after it starts. We remind you before the deadline. If the payment is not made through Diomgis, or you have not told the mentor you paid them directly, by the deadline, the session is released: it is cancelled with the reason "not paid by the deadline", and both of you are told.
  • No changes or refunds after confirmation: once the mentor confirms a session, it cannot be changed or refunded. We tell you this before you pay. If you cancel a confirmed session, you lose it and are not refunded, and the mentor is still paid.
  • One emergency change: once in the life of your account, across all mentors, you may ask to move a confirmed session for an emergency, with a reason and a proposed new time. If the mentor accepts, the session moves and your emergency change is used. If the mentor declines, the session stays as it was and your emergency change is not used. Once it is used, it is gone.
  • If a mentor cannot attend: a mentor who cannot make a confirmed session must propose a new time; they cannot cancel it. You can accept the new time, or tell us through the contact form. There are no automatic refunds: we look at each case. A move the mentor starts does not use your emergency change.
  • Cancelled before confirmation: if a session you paid for through Diomgis is cancelled before the mentor confirms it, by either of you, or because the mentoring ends or the mentor leaves, we refund the payment in full to the original payment method. If you paid the mentor directly for such a session, the mentor should return the payment; we cannot do that for them, but please tell us through the contact form if a mentor does not.
  • Testimonials: after a completed session you may write one testimonial for each mentorship, with a rating from 1 to 5 if you wish. It is shown on the mentor's public profile under your first name and last initial, or as "a mentee", as you choose. You can edit or delete it at any time. The mentor can report a testimonial to us, and we may hide one that breaks these terms.

7. Assessment and certificates

A certificate is issued when you meet a course's published assessment requirements. Your work must be your own; where AI tools are allowed, you must say how you used them. We may withhold or withdraw a certificate obtained through plagiarism, cheating or impersonation. Diomgis is not a university or an accredited higher-education institution. References to EQF levels and ECTS credits describe the level and workload of a course for transparency; they are not academic credit, and we do not guarantee that any employer or institution will recognise a certificate.

8. AI features

Where the Platform offers AI-assisted tools, their answers are generated automatically and may be wrong or incomplete. They support your learning and do not replace professional advice or your own judgement. Use of AI features may be subject to fair-use limits shown in the Platform. Do not enter other people's personal data or confidential information into them. Each answer can be reported to us from the Platform.

9. Acceptable use

You agree not to: share your account or course materials with people who have not enrolled; copy, resell or publish course materials or recordings; harass, threaten or discriminate against anyone; post unlawful or infringing content; attempt to access systems or data you are not authorised to access, or disrupt the Platform; or use automated tools to scrape it. We may remove content and suspend or close accounts that break these rules, and in serious cases without refund.

10. Intellectual property

Course materials, recordings, software and the Diomgis name belong to Sigmoid Vedanta Technologies or its licensors. When you enrol you receive a personal, non-transferable licence to use the materials of that course for your own learning for as long as you have access to it. Work you submit remains yours; you allow us and your mentors to use it to assess you and give feedback, and we will ask before showcasing it anywhere.

11. Access period

You can use the materials and recordings of a course for 12 months after your cohort's last session, unless the course page says otherwise. Certificates you have earned remain verifiable after that.

12. Cancellations and refunds

Cancellations and refunds are governed by our Cancellation and Refund Policy, which forms part of these terms. For mentoring sessions, see its Mentoring section and section 6 above.

13. No guarantee of outcomes

We teach carefully and support you through the course, but learning outcomes depend on your own effort. We do not promise any job, placement, promotion, salary or examination result.

14. Our responsibility to you

We will provide our services with reasonable care and skill. Nothing in these terms limits your rights under the Consumer Protection Act, 2019 or any other law that cannot be limited by agreement. Otherwise, and to the extent the law allows, we are not liable for indirect or consequential loss, and our total liability to you for any claim is limited to the amount you paid us for the service concerned in the 12 months before the claim arose.

15. Suspension and closure

You can stop using the Platform and delete your account at any time. We may suspend or close an account that breaches these terms, or where the law requires us to, and will tell you why unless the law prevents it.

16. Third-party services

Payments, video sessions and community channels are provided through third parties, including Razorpay, Zoom, Google and Discord, whose own terms also apply to your use of their services.

17. Changes to these terms

We may update these terms. For significant changes we will email registered users at least 14 days before they take effect. The effective date at the top shows the current version. Changes do not apply to purchases completed before they take effect.

18. Governing law and disputes

These terms are governed by the laws of India, and the courts at Thiruvananthapuram, Kerala have jurisdiction. This does not affect your right to approach a consumer disputes redressal commission, or any mandatory consumer protections of the country where you live. Please contact us first: most problems can be solved quickly.

19. Grievances and contact

Questions and complaints can be sent to us with the contact form, or by phone on +91 77367 53888. Our Grievance Officer is Sigmoid (email contact@diomgis.com), who acknowledges complaints within 48 hours and resolves them within one month; to complain, choose a complaint to our Grievance Officer on the contact form. Our email address is contact@diomgis.com and our postal address is Sigmoid Vedanta Technologies, 5/2197, CHERUVICKAL, SREEKARYAM - 695017.
