What we collect

To improve the website, we record how it is used: pages visited, buttons and Pihu options tapped, questions typed to Pihu, the time, your browser language, time zone and device type (mobile or desktop). We do not use advertising cookies and we do not record your IP address.

When you book or contact us

When you request a session or send a message, the details you enter (name, email, session, date, time and message) are recorded in our records and sent from your email app to sachintekriwalai@gmail.com. We use them only to reply and arrange your session. They are not sold or shared.

WhatsApp follow-up (optional)

After a few questions, Pihu may ask if you'd like course details on WhatsApp. It is optional. If you agree, your name, mobile number and topic of interest are sent to Sachin's team only when you tap Send, and are used only to contact you about learning.

Learner accounts (learn.sachintekriwal.com)

If you create an account we store your name, email, optional mobile number, country, the courses you enrol in and your learning progress and notes, in Google Firebase. Only you and our teachers can see them. You can ask us to delete your account at any time by writing to sachintekriwalai@gmail.com.

Payments

Payments are handled by Razorpay (India) or our international payment provider on their own secure pages. We never see or store your card or bank details; we only receive the payment reference to confirm your enrolment.

Where it is stored

For now, usage records stay in your own browser as small text entries, and anything you send reaches us by email or WhatsApp. You can clear them anytime by clearing this site's data in your browser.

On your device

Your light/dark choice is saved in your browser and never leaves your device.

Fonts and links

Fonts are loaded from Google Fonts. Links to LinkedIn, YouTube, GitHub, Medium, ORCID and other sites follow those sites' own privacy policies.

Questions

Email sachintekriwalai@gmail.com to ask about, correct or delete any information you have sent us.
