This policy covers paid Standard and Premium subscriptions on StemPy Lab. The Free plan has no charge and nothing to refund.
Paid plans are prepaid for one month or one year at a time and never renew automatically, so there is nothing to cancel and you are never charged without choosing to pay. When the period you paid for ends, your account moves to the Free plan. We remind you before that happens, and you can renew whenever you like.
If this is your first time buying a paid plan and you're not satisfied, you can request a full refund within 7 days of that payment by contacting us at the email below. This one-time window applies to your first paid-plan purchase only, not to later purchases or renewals.
Outside the money-back window above, payments for plan time are non-refundable. Buying the same plan again before it ends adds the new time onto your current end date, so renewing early never wastes days. Upgrading from Standard to Premium starts Premium straight away, and your unused Standard days are converted into extra Premium days in proportion to the two plans' monthly prices. You can't move down from Premium to Standard while Premium is active; it simply ends at its end date.
Separately from your subscription tier, an individual piece of content (a problem, quiz, lab, mock test, question set, course, resource, or note) can itself be tagged Standard or Premium by an admin, restricting who can open it regardless of who authored it. If your plan lapses, is downgraded, or reverts to Free (including at the end of a refunded plan), you lose access to any content tagged above your current tier immediately, the same way a Free account would. This isn't a separate charge or refundable item on its own. It follows your subscription tier automatically.
If a payment fails, you aren't charged and your plan doesn't change; you can simply try again. If money left your account but your plan didn't update within a few minutes, or you believe you were charged in error, contact us first. We aim to resolve billing issues directly rather than through a card network dispute, which takes longer for everyone.
Approved refunds are issued to your original payment method and typically reflect within 5-7 business days, depending on your bank or card issuer's own processing time. When a payment is refunded, the plan time it bought is removed from your account at the same time.
This policy is governed by the laws of India, without regard to conflict-of-law principles. Any dispute arising from this policy or a billing matter is subject to the exclusive jurisdiction of the courts at Arambagh, District Hooghly, West Bengal (and, where the value or nature of a claim requires, the District Court at Chinsurah, Hooghly), and the Calcutta High Court on appeal.
