Privacy policy

Last updated 26 October 2026

Yantrika (operated by Atul Rai) operates yantrika.shop. This policy explains what we collect and why.

What we collect

• Your wish and the name you engrave, to make and deliver your Yantrika.
• Your touch readings (contact size, pressure, tremor and hold time) and the time, used in the calculation.
• Your location, only if you choose to share it. It is rounded to about 1 km before it is used or stored. Without it, your time zone is used.
• Payment details from Razorpay: payment id, email and phone number, for receipts and support. We never receive card, UPI or bank details.

Before payment, a Yantrika is calculated on your device; nothing is stored on our server until you choose to buy. On this device we keep a short list of designs you have seen and your cycle marks, in your browser’s storage.

How we use it

Only to create, deliver and support your Yantrika and to meet legal and accounting obligations. We do not sell your data, show advertising, or use tracking cookies.

Who processes it

Cloudflare hosts the site and its database; Razorpay processes payments. Both act under their own privacy and security commitments.

How long we keep it

Paid Yantrikas are kept so your private link keeps working. Ask us at contact@yantrika.shop to delete yours, and we will do so within 30 days, except records we must keep by law.

Your rights

You may ask to access, correct or delete your data under India’s Digital Personal Data Protection Act, 2023. Write to contact@yantrika.shop.
