Privacy Policy
Last updated: 22 October 2026
This Privacy Policy explains how BinaryTrees Academy ("BinaryTrees", "we", "us") collects, uses and protects personal information when you use binarytrees.in, contact us, enrol in a course or attend our classes.
1. Information we collect
We collect only the information we need to run our courses:
- Enrolment and contact details you give us — the student's name, class, school and city, and the parent or guardian's name, phone number and email address.
- Messages you send us by WhatsApp, phone, email or our contact form.
- Payment details — when you pay online, our payment partner Razorpay processes the payment. We receive the transaction ID, amount, status and the contact details entered on the payment page. We never receive your card number, UPI PIN or bank login details.
- Class and learning records — such as the name and email used on Google Classroom or Google Meet, attendance, submitted work and test scores.
2. Website, cookies and analytics
Our website uses the Meta Pixel, a tool from Meta Platforms (the company behind Facebook and Instagram). It sets a cookie and tells Meta which pages of our site are visited and which buttons are used — for example opening a course page, viewing the fee, opening an FAQ, or tapping WhatsApp, call, enrol or pay — along with technical information such as your browser and IP address. It does not send what you type into forms or your answers to the readiness self-check. We use it to measure how well our Facebook and Instagram ads work and to show our ads to people who have visited our website. Meta handles this information under its own privacy policy. You can control ad personalisation in your Facebook / Instagram ad settings, or block cookies in your browser.
We also use Google Analytics, a service from Google, to understand how the website is used — for example how many people visit, which pages they view, how long they stay, and the type of device and approximate location (city or region) they visit from. It uses cookies to tell visits apart. We use these reports only to improve the website; we do not use Google Analytics for advertising. Google handles this information under its own privacy policy. You can opt out using Google's browser add-on (tools.google.com/dlpage/gaoptout) or by blocking cookies in your browser.
We also use Microsoft Clarity, a service from Microsoft, to see how visitors use our pages through heatmaps and recordings of clicks, taps, scrolling and mouse movement. Clarity hides what you type into forms, and we have set it to hide the readiness self-check, so your answers are not recorded. We use it only to fix problems and make the website easier to use, not for advertising. Microsoft handles this information under its own privacy statement. You can block it by blocking cookies in your browser.
We do not use any other analytics or advertising tools on the website.
Like any website, our hosting and security provider automatically processes basic technical information — such as IP address, browser type and the pages requested — to deliver the site and protect it from abuse.
Our contact form does not store your message on our website. It opens your own email app with the message filled in, and you choose whether to send it.
3. How we use your information
We use personal information to:
- Answer enquiries and help you choose a course.
- Confirm enrolments, process payments and send receipts.
- Share class joining details and add students to Google Classroom and class groups.
- Teach classes, run tests and share progress with parents.
- Send course updates, schedule changes and important notices.
- Tell you about future batches or courses — you can opt out at any time.
- Keep the records we are required to keep by law, such as payment and tax records.
4. Children's information
Most of our students are under 18. We collect a student's information from, or with the consent of, their parent or guardian, and we use it only to provide our courses.
Our advertising is aimed at parents and guardians. We do not use the enrolment, class or learning information we hold about students for advertising, and we do not knowingly direct ads at children.
A parent or guardian can ask us at any time to see, correct or delete their child's information by contacting us using the details below.
6. How we protect and keep your information
We use reasonable security measures to protect personal information and limit access to the people who need it to run our courses.
We keep information for as long as the student is enrolled and for a reasonable period after, so we can answer questions and support future enrolments. Payment and tax records are kept for as long as the law requires. After that, information is deleted or anonymised.
7. Your rights
Under Indian data protection law, you can:
- Ask what personal information we hold about you or your child.
- Ask us to correct or update it.
- Ask us to delete it, unless we must keep it by law.
- Withdraw your consent to us using it — this may mean we can no longer provide a course.
- Stop receiving promotional messages, by replying STOP on WhatsApp or emailing us.
- Raise a complaint with us, and if you are not satisfied, with the Data Protection Board of India.
To make any of these requests, email contact@binarytrees.in. We may need to confirm your identity before acting on a request.
8. Links to other websites
Our website links to other services, such as WhatsApp, Google Maps and our social media pages. Their own privacy policies apply when you use them.
9. Changes to this policy
We may update this Privacy Policy from time to time. The latest version will always be on this page with its "Last updated" date.
