Privacy policy

Effective 9 November 2026

Zenterra ("Zenterra", "we", "us") is owned and operated by Chiransh Kalra in India. Zenterra provides software that lets fashion stores answer their customers on WhatsApp and other messaging apps with an AI shopping assistant. This policy explains what information we handle, why, and the choices you have.

Who this policy covers

• Stores that use Zenterra (our business customers) and their staff.
• Shoppers who message a store that uses Zenterra on WhatsApp, Instagram, Telegram or the store's web chat.
• Visitors to this website.

Information we collect

From stores

• Account details: email address, business name, address and contact number.
• Messaging account details: the store's WhatsApp Business account and phone number identifiers, and the access tokens Meta issues so we can send messages for the store. Tokens are stored encrypted.
• Catalog: product names, prices, stock, categories, attributes and photos.
• Messages the store's staff send to shoppers from the Zenterra dashboard, or from the WhatsApp Business app on the connected number.

From shoppers, on behalf of the store

• Your profile name and phone number or account ID on the messaging app.
• The messages, button taps and replies you send to the store, and the replies the store and its assistant send you.
• When you order: your name, phone number, delivery address, PIN code, the items and your choice of payment method (Cash on Delivery or online). We don't collect card, UPI or bank details.
• A short shopping profile built from your chats, such as sizes, style preferences, budget, occasion and products you liked, so the assistant doesn't have to ask again. Each fact is dated, and older ones expire.
• If a store connects a number it also uses in the WhatsApp Business app, the app's recent chat history (up to the last 180 days) may be imported, so the store's inbox and the assistant have context.

From website visitors

This website doesn't use cookies, analytics or advertising trackers. Our hosting provider may keep standard server logs, such as IP addresses and the pages requested, for security.

How we use information

• To answer shoppers' messages for the store: understand the question, find matching products in that store's catalog and write the reply.
• To take orders in the chat and show them to the store, and to tell shoppers when the store approves, rejects or delivers an order.
• To hand conversations to the store's staff when needed, and to show the store its chats, orders and shopping profiles in its dashboard.
• To keep the service secure, fix problems and improve the quality of answers.

We don't sell personal information, use it for advertising, or use one store's data for another store.

AI processing

Messages, catalog details and product photos are processed by Google's Gemini AI models to understand questions, describe products and write replies. Replies are generated automatically and can contain mistakes. The store reviews every order before accepting it.

Who we share information with

• The store you are chatting with. It can see your chats, your shopping profile and your orders, and uses them under its own terms and privacy practices.
• Service providers that run the service for us: Meta Platforms (WhatsApp and Instagram messaging), Telegram (Telegram messaging), Google Cloud (AI models and message processing) and our hosting providers. They process the data only to provide their services.
• Authorities, when the law requires it or to protect people's rights and safety.

Stores and shoppers: who decides

For shoppers' information, the store decides why and how it is used, and Zenterra processes it on the store's behalf. Under India's Digital Personal Data Protection Act, 2023, the store is the Data Fiduciary and Zenterra is its Data Processor. Shoppers can send requests to the store or to us; we pass them to the store where needed.

How long we keep information

• Chat messages: up to 12 months, then deleted. The short shopping profile is kept while the store uses Zenterra.
• Orders: while the store's account is active, so the store can look up past orders.
• Store accounts: until the account is closed. We then delete the store's data within 30 days, except where the law requires us to keep it.
• Disconnecting a WhatsApp number deletes its stored access token straight away.

Security

Data is sent over encrypted connections (HTTPS). Stored messaging access tokens are encrypted, and access to our systems and data is limited to people who need it. No system is perfectly secure, but we work to protect your information, and we will tell affected stores of a breach as the law requires.

Your choices and rights

You can ask to see, correct or delete your personal information, or withdraw your consent, by emailing us. Shoppers can also stop messaging the store at any time or block its number in the messaging app. See how to delete your data. We reply within 30 days.

Children

Zenterra is meant for businesses and adult shoppers, and we don't knowingly collect information from children under 18. If you believe a child has shared information through Zenterra, contact us and we will delete it.

Changes to this policy

We will post any change on this page with a new effective date. For significant changes, we will also tell stores by email.
