Privacy policy

Last updated: 11 November 2026

This policy explains what information K2 Karakoram collects, why it is used and how it is protected.

1. What we collect

• Without sign-in: nothing is sent to us. Progress and settings stay only on your phone (in the browser).
• When you sign in with Google: name, school name, village/city, class, board, chosen exams, email (from the Google account), test results and concept-wise progress.
• Teachers and institutes: teacher code, classes, tests they create, and the institute's name and place.
• Devices used with your account: when you are signed in, the app notes roughly once a day which phone or computer is using the account: a random number made by the app for that browser, the type of device and browser (for example "Android · Chrome"), and the date. We use this only to notice if one paid account is being shared by many people. We do not record your location or phone number.
• When you buy a plan: the plan, amount, date, the Razorpay order ID and payment ID, and the payment status. The plans you bought and their end dates are saved with your sign-in account.

We do not receive or store card numbers, UPI PIN, net-banking passwords or bank account details. These are handled by Razorpay on its secure payment page.

2. Why we use it

To keep the student's progress, restore it on a new phone, show teachers which concepts are weak, show the teachers' institute (school / coaching class) the results of their classes, open the plans you bought, answer help and refund requests, and keep our accounts records. The data is not used for advertising and is not sold.

3. Where it is stored and who can see it

Data is stored on Google Cloud (Firebase). The app is hosted on Cloudflare and payments are made through Razorpay. Only the student, the authorised teachers of their school/class, and the institute (school / coaching class) those teachers have joined can see it. The institute sees only the names and test results of students in those teachers' classes and cannot change anything. We (the publisher) look at your information only when it is needed for help or a refund.

4. Ranking (optional)

Only if a student gives consent and chooses "Join the ranking", their first name, school name, village/city, class, number of tests solved and points are shown to other signed-in students of the app. The surname, email and details of wrong answers are not shown. A student can leave at any time with "Leave the ranking", which removes their entry from the list.

5. Access codes

An access code can be used only after signing in. The code is sent to our server only to check it. If it is valid, only the date until which it is valid is saved with the student's sign-in account. The code itself is not stored.

6. Payments

Plans are paid for on the secure page of Razorpay, a payment company. Razorpay's own privacy policy applies to the details you enter on that page. Razorpay tells us only whether the payment succeeded, the amount, the date and the payment ID. If a student gets an access code from the publisher instead, the money is paid from the student's own UPI app under the rules of that app and bank.

7. Children and parental consent

Students under 18 need a parent's or guardian's consent to sign in. The consent tick shown at sign-in records this. A parent can withdraw consent at any time. Payments for students under 18 should be made by a parent or guardian.

8. How long we keep data

Learning data is kept until you delete it or ask us to delete it. Payment records are kept for as long as accounting and tax laws require.

9. Your choices and rights

• See, correct or delete your information: use the "Delete my online data" button in the app, or write to support.k2karakoram@gmail.com.
• A parent can withdraw consent at any time.
• You can leave the ranking at any time.

We reply to such requests within 30 days.

10. Security

Sign-in is through Google, online data is protected by access rules, and all communication uses HTTPS. Even so, no online method is 100% secure.

11. Other services we use

Google (Firebase sign-in and database, fonts), Cloudflare (hosting) and Razorpay (payments) handle information under their own policies.

12. Grievance officer

Ranjeet Anil Sawant · support.k2karakoram@gmail.com · +91 76661 20535. We acknowledge a complaint within 48 hours and resolve it within 30 days.

13. Changes
