Terms of Service

These Terms of Service ("Terms") are an agreement between you and Somdeb Mandal, trading as Grinkif, Kolkata, West Bengal, India ("Grinkif", "we", "us"), for the use of the Grinkif learning app and the website grinkif.com (together, the "Service"). By creating an account or buying a plan, you agree to these Terms, our Privacy Policy and our Cancellation & Refund Policy. Please read them carefully.

1. Who can use Grinkif

Grinkif is a learning service for children in Classes 1–5. Accounts may only be created by an adult (18 or over) who is the parent or lawful guardian of the children they add ("you"). Children use Grinkif through a child profile inside your account, under your supervision. You are responsible for your children's use of the Service and for making sure these Terms are followed.

2. Your account

• Give accurate information and keep your sign-in details private. You are responsible for activity on your account.
• You can add up to 2 child profiles per parent account. A third child needs a separate parent account.
• You can protect Parent Zone with a PIN. Please do so if your child uses the same device.
• Tell us straight away at support@grinkif.com if you think someone else has accessed your account.

3. The free trial

• Each new parent account may have one free trial: 14 days, for 1 child and 1 subject you choose (all its topics or the topics you select), with every feature, including 3 school-format and 3 Olympiad-style full-length mock tests in that subject (for Hindi, Bengali and Moral Science, which have no Olympiad, 3 Challenge mock tests instead).
• You can create an account without starting the trial. The trial starts on the day you choose to start it in the app (day 1) and ends at 11:59 pm IST on day 14. We remind you in the app on day 10.
• No payment details are needed for the trial, and you will not be charged when it ends.
• When the trial ends, your child's learning (lessons, practice and mock tests) locks until you buy a plan. Parent Zone, progress and reports stay available to you.
• Creating extra accounts to get more free trials is not allowed. We may refuse or end trials that we reasonably believe are repeats.

4. Plans, prices and payment

• All prices are in Indian rupees and include GST where applicable. The price you'll pay is shown before you confirm.
• Each plan is for one child. Every child who uses a paid plan needs their own plan.
• Sibling discount: both children are on one family subscription with one billing period. The second child gets 20% off, applied to the cheaper of the two plans. If a child is removed, the discount ends at the next renewal.
• "All subjects" means every subject Grinkif offers for your child's class and board at the time. The list of subjects and topics may change as we add or improve content.
• Payments are processed by Razorpay (UPI AutoPay, debit or credit card, or net banking). Razorpay's terms also apply to the payment. We never see or store your full card number or UPI PIN.
• Razorpay emails a receipt for each payment.
• Price changes: if we change prices, the new prices apply to new subscriptions. Existing subscribers keep their price for as long as their subscription continues without a break.

5. Auto-renewal

• Paid plans are subscriptions that renew automatically at the end of each billing period (monthly or yearly) until you cancel. By subscribing, you authorise us, through Razorpay, to charge the plan price, less any Grinkif Credit you choose to use, to the payment method or mandate you set up (UPI AutoPay or card mandate) on each renewal date. We show the exact amount in the app 3 days before each charge.
• You can instead choose to pay by hand each period. If a manual payment isn't made by the end date, the grace period below applies.
• Your bank or UPI app may send you a pre-debit notification before a renewal, as RBI rules require for recurring payments.
• If a renewal payment fails, you get a 3-day grace period with a notice in the app. If payment still hasn't gone through, your child's learning locks (progress and reports are kept) until payment is made, and the subscription resumes when it is.

6. Cancelling

• You can cancel any time in Parent Zone → Plan & billing, or by emailing support@grinkif.com from your account email. If you pay by UPI AutoPay, cancelling the mandate in your UPI app also stops renewals.
• Cancelling turns off the next renewal. Your plan stays active until the end of the period you have already paid for, and then ends. Your child's progress is kept, so you can resubscribe later.

7. Refunds

No refunds once a plan is purchased. The 14-day free trial lets you try every feature before paying. Payments for monthly and yearly plans are not refundable, in whole or in part, including for unused time, unused subjects or early cancellation. The only exceptions are duplicate charges and charges for payments that failed, which we refund in full. The full rules are in our Cancellation & Refund Policy, which forms part of these Terms. Nothing in these Terms limits any right you have under Indian consumer protection law that cannot be excluded.

8. Changing plans

• Upgrade from 1 subject to all subjects: access opens straight away, and you pay the pro-rated difference for the rest of the current period.
• Downgrade from all subjects to 1 subject: takes effect at your next renewal.
• Monthly to yearly, or yearly to monthly: takes effect at your next renewal.
• Changing the subject on a 1-subject plan: allowed once per billing period. Progress in the previous subject is kept.

9. Referral rewards

• You can share your personal invite link or code from Parent Zone. You must share it yourself, honestly, and only with people who would welcome it. No spam, and no paid ads that use our brand name.
• A referral qualifies when a new family (a new parent account that has never had a trial) signs up with your link or code, completes its free trial and makes its first successful payment.
• For each child the referred family pays for, you get ₹100 Grinkif Credit. It shows as pending for 7 days after the friend's payment, then joins your balance. Grinkif Credit can be used only to pay for Grinkif plans. It is never paid as cash or refunds, has no cash value and can't be transferred.
• There is no limit on how many families you can refer. Unless you switch it off in Plan & billing, your balance is used on your next payment, whether you renew automatically or pay by hand. If the balance covers the whole payment, nothing is charged that period and the rest carries over. If you aren't subscribed when credit is earned, it waits for your first payment. If you cancel, your balance is kept for 6 months after your paid period ends and then expires.
• No reward is given if the referred account shares your email (including variants of the same address), phone number, payment method or device, or if the friend's payment is refunded or charged back (credit already in your balance is then removed, never below ₹0), or if we reasonably believe the referral is not genuine. The friend receives the normal free trial and no additional reward.
• We may change or end the referral programme for future referrals by giving notice in the app. Rewards already earned will be honoured.

10. Acceptable use

You agree that you and your children will not:

• share one child's plan between several children, or use one account for children outside your family;
• use Grinkif for a tuition centre, coaching class, school or any other business, for example by using it with many students, projecting it to a class, or reselling access, without a separate written agreement with us;
• share your sign-in details with people outside your household;
• copy, download in bulk, scrape, republish or sell our questions, lessons, mock papers, answer keys, illustrations or other content;
• try to get around locks, payments, plan limits or the free-trial rules, or interfere with the security or running of the Service;
• reverse-engineer the app, except where the law allows it;
• upload anything unlawful, harmful or that you don't have the right to share;
• use the Service in a way that breaks any law.

We may look for unusual use (for example, many devices at the same time, or very long daily use) to protect fair use, and contact you or take action if needed.

11. Learning content and AI

• Grinkif follows the CBSE and ICSE syllabus for Classes 1–5 as closely as we can, but it is practice and revision alongside school, not a replacement for school or teachers. Grinkif is not affiliated with or endorsed by CBSE, CISCE or the Science Olympiad Foundation (SOF). Olympiad names are used only to describe the format of our practice papers.
• We work hard to make content accurate. Mistakes can happen; please use Report a mistake and we will fix confirmed errors.
• Some hints, explanations, practice questions and writing feedback are generated with AI (see our Privacy Policy). Correct answers are decided by our own checked content.
• We don't promise any particular marks, grades, ranks or exam results. Results depend on many things outside our control.

12. Intellectual property

Grinkif, the Grinkif logo, the Chikiti character and friends, and all content in the Service (including lessons, questions, mock papers, illustrations, text, design and software) belong to us or our licensors and are protected by law. We give you a personal, non-exclusive, non-transferable, revocable licence to use the Service for your own family's learning while your account is in good standing. You may print mock papers and answer keys for your own child's use only. Anything your child writes in the app remains yours; you let us store and process it to provide the Service.

13. Availability and changes

We aim to keep Grinkif available and improving, but it may sometimes be unavailable for maintenance or reasons outside our control. We may change, add or remove features and content. If we make a change that significantly reduces what you've paid for during a paid period, we will tell you and, where fair, offer a remedy such as extra time.

14. Suspension and termination

You may stop using Grinkif and delete your data any time. We may suspend or close an account that seriously or repeatedly breaks these Terms, misuses the Service or is used fraudulently (for example, chargebacks made in bad faith), after giving notice where reasonable. If we close your account, we will refund the unused part of your current paid period to the original payment method (less any amount already returned to you through a chargeback).

15. Disclaimers

Apart from what these Terms expressly say, the Service is provided "as is" and "as available". To the extent the law allows, we don't give any other promises or warranties, including that the Service will be uninterrupted or error-free, or that it will meet a particular educational outcome.

16. Limitation of liability

To the extent the law allows: (a) we are not liable for indirect or consequential loss, or loss of opportunity, data or goodwill; and (b) our total liability to you for all claims relating to the Service is limited to the amount you paid us in the 12 months before the event giving rise to the claim. Nothing in these Terms limits liability that cannot be limited by law, including for fraud or for death or personal injury caused by negligence.

17. Governing law and disputes

These Terms are governed by the laws of India. Please contact us first, and we will try to resolve any concern quickly and fairly. If a dispute can't be resolved, the courts at Kolkata, India will have exclusive jurisdiction, without affecting your right as a consumer to approach a Consumer Disputes Redressal Commission under the Consumer Protection Act, 2019.

18. General

• We may update these Terms. For important changes we will tell you in the app or by email before they take effect. If you keep using Grinkif after that, the new Terms apply; if you don't agree, you can cancel.
• If any part of these Terms is found invalid, the rest remains in force.
• You may not transfer your account. We may transfer these Terms to a business that takes over Grinkif, with the same protections for you.
• These Terms, the Privacy Policy, the Cancellation & Refund Policy and the Delivery Policy are the whole agreement between us about the Service.
