How billing works
Every paid plan is an Autopay subscription, paid in advance through Razorpay by UPI Autopay or card, and it renews by itself until cancelled. You can cancel at any time in Settings; your plan stays until the end of the time you have paid for.
Offer codes are earned (for example, by early members at sign-up), belong to one account and can be used once. After the 6 offer months, we send a link to continue at the full price, which you approve before anything more is charged.
For a limited time, early members can join at an introductory price of ₹2,499 + GST for a full year (365 days) of Plus, paid at the start of the year. After the first 365 days, Plus renews each year by Autopay at ₹4,999 + GST, still well below the monthly price of ₹699. The introductory price is for a family's first Plus payment and ends soon.
Question top-ups can be bought on the Plus plan only, not on Free: ₹199 + GST adds 90 questions, used only after the day's or month's questions run out, and they never expire.
