Privacy Policy

Last updated: 18 June 2026

1. Who we are

PratiPariksha ("we", "us", "our") is a learning platform operated by ChemYukti, India. You can reach us any time at chemyukti@gmail.com or pratipariksha@gmail.com. This policy explains what we collect when you use pratipariksha.com and our related apps and services.

2. What we collect

• Information you give us: your name, email, phone number and message when you ask for help, request a school demo, register for CHET, or create an account (username + password).
• Practice & learning activity: the grade, subject and exam you choose, questions served, answers, and quiz/game scores — so we can run the practice engine and show your progress.
• A device identifier ("fingerprint"): a code generated from your browser/device (and stored in your browser) so we can apply free-question limits, remember purchases, and prevent abuse — without forcing you to log in.
• Technical data: IP address, approximate country/region (from your network), time zone, language and browser type.
• Chat data: messages you send to PratiBot, our study assistant, so it can reply and so we can improve it.
• Payment data: when you buy something, payment is processed by Razorpay. We receive a payment/order ID and status — we never see or store your full card, UPI or bank details.

3. How we use it

• To run the service — serve practice questions, games, resources and the CHEA path.
• To enforce free limits, unlock paid features, process payments and issue refunds.
• To respond to your help requests and school/demo enquiries.
• To keep the platform secure and prevent cheating or abuse.
• To understand usage and improve PratiBot and our content.

4. Cookies & local storage

We use a small session cookie to keep you signed in, and your browser's local storage to hold your device identifier, theme choice and referral code. We do not use third-party advertising cookies beyond Google AdSense (below). You can clear these any time from your browser settings.

5. Third parties we share with

We do not sell your personal data. We share the minimum necessary with service providers who help us operate:

• Razorpay — to process payments (governed by Razorpay's own privacy policy).
• Cloudflare — which powers PratiBot's AI responses.
• Google AdSense — if ads are shown, Google may use cookies to serve relevant ads. See Google's ads policy.
• Email/SMTP providers — only to deliver your support or enquiry messages to our team.

6. Children's privacy

PratiPariksha is built for students, including those under 18. We collect only what is needed to provide learning features and we do not knowingly use children's data for advertising profiling. If you are a parent or guardian and want a child's data removed, email us and we will act promptly.

7. Data retention

We keep your data only as long as needed to provide the service and meet legal/accounting requirements. You can ask us to delete your account data at any time (see below).

8. Your rights

You can ask us to access, correct or delete your personal data, or to stop processing it. Email chemyukti@gmail.com and we will respond within a reasonable time.

9. Security

We use HTTPS, hashed passwords, server-side enforcement of all paid logic, and httpOnly session cookies. No system is perfectly secure, but we take reasonable measures to protect your information.

10. Changes

We may update this policy from time to time. The "last updated" date above will always reflect the current version. Significant changes will be highlighted on the site.
