Short, plain, and honest. Like everything else here.

Last updated: September 2026. This policy applies to zerotodev.in and everything sold through it.

What we collect

When you DM us or email us, we receive what you send: your name, your Instagram handle or email address, and your message. When you pay, your payment is processed by UPI through your own payment app. We see the payment confirmation and the name or ID attached to it. We never see and never store your UPI PIN, card numbers or bank login.

Why we collect it

One reason only: to deliver your workbook, send you updates you are entitled to as a buyer, and support you if something goes wrong. If you message us asking for the free sample, we use your contact to send the sample and nothing else.

What we never do

We do not sell, rent or trade your information. We do not share it with advertisers. We do not send marketing you did not ask for. If you bought the workbook, you may occasionally get a genuine product update, and every one of those messages will tell you how to stop them in one line.

Cookies and analytics

This site runs no advertising cookies of its own. If we later add privacy-respecting analytics to understand which pages help people, this section will be updated before that happens, and the update date at the top will change.

Data deletion

Want your data deleted? One message to hello@zerotodev.in or a DM to @zerotodev with the word DELETE. We remove your contact details within 7 days and confirm it back to you, except the records we must keep for accounting and refund obligations under Indian law.
