Privacy Policy

How Greentek collects, uses and protects your information.

Last updated: 11 August 2026

Greentek India Limited ("Greentek", "we", "us") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, disclose and safeguard your information when you visit our website, submit an enquiry or communicate with us through WhatsApp or another messaging channel.

Information we collect

We may collect personal information such as your name, phone number, email address, city and project requirements when you fill out a lead form, request a quote or contact us. We also collect standard web log data and use cookies and similar technologies to improve your experience.

WhatsApp and other messaging channels

When you message us through an official Greentek WhatsApp channel, including our automated assistant on +91 88977 44474, a Chat on WhatsApp button on our website or advertisement, or one of our QR codes, we receive and store:

  • Your WhatsApp phone number and the profile name you have set on WhatsApp.
  • The content of the messages you send us, including any photographs or documents you choose to share, and our replies.
  • The date and time of each message and its delivery status.
  • Where you reached us from an advertisement, the identifier of that advertisement or campaign.
  • The answers you give to our questions about your requirement, for example your city, approximate monthly electricity bill band, roof type and area, sanctioned load, whether you own the premises, and your expected timeline.
  • Your preferred language, so we can reply and call you in it.
  • Whether you have consented to receive updates from us, and the date and time of that consent.

When you message us for the first time from a number we do not recognise, we create an enquiry record so that a member of our team sees your message and can respond. We ask for your consent before we record any further details about your requirement.

Some of our replies are sent automatically by a WhatsApp assistant rather than typed by a person. You can ask to speak to a person at any point by replying with "agent", "human" or "call me", and we will pass the conversation to our team.

What we will never ask for on WhatsApp

We do not ask for, and you should never send us over WhatsApp, your Aadhaar number or a photograph of your Aadhaar, your bank account or card details, or a one-time password (OTP) of any kind. If we need your electricity bill, we ask only for the consumer number, or we collect the bill at the site visit. Anyone asking you for these things on WhatsApp in Greentek's name is not us. Please report it using the details in Contact us.

WhatsApp is operated by Meta Platforms, Inc. Your use of WhatsApp is governed by WhatsApp's own privacy policy, which we do not control.

How we use your information

  • To respond to your enquiries and provide solar consultations.
  • To process proposals, quotations and project documentation.
  • To send service updates, offers and marketing communications with your consent.
  • To analyse website traffic and improve our services.

We use the information you send us on WhatsApp to answer your question, understand what system would suit your premises, arrange and confirm a site assessment, send your proposal and updates on your own installation or service request, and keep a record of your enquiry so that any colleague you speak to later has the context.

We send two different kinds of WhatsApp message, and we treat them differently:

  • Messages about your request: These include messages about your enquiry, appointment, proposal, installation, subsidy application or service ticket. We send these because you asked us for something and we are following through on it.
  • Promotional messages: These may include an explanation of the PM Surya Ghar subsidy or an offer of a free site assessment. We send these only if you have told us we may. We limit promotional WhatsApp messages to a maximum of three per person in any 30-day period, and we stop the sequence as soon as you reply.

We do not use your WhatsApp messages to build advertising profiles, and we do not share them with advertising networks.

Stopping messages from us

You can stop promotional messages from us at any time, at no cost, by replying to any of our WhatsApp messages with STOP. We also recognise UNSUBSCRIBE and equivalents in Hindi and Telugu, including band karo, mat bhejo, ఆపు and వద్దు.

We act on this immediately and automatically. Your number is marked as opted out and removed from every promotional sequence. You do not need to give a reason or speak to anyone.

Opting out does not stop messages about something you have specifically asked us for, such as a booked site visit, requested proposal, subsidy application or service ticket. To stop those as well, or to close your enquiry entirely, write to us using the details in Contact us.

We keep a record of the fact that you opted out, and the number it applies to, for as long as we operate this channel. This record is necessary to make sure we do not message you again.

Sharing your information

We do not sell your personal information. We may share data with trusted service providers, financing partners and regulatory authorities only where necessary to deliver our services or comply with legal obligations.

How long we keep your information

We keep personal data only for as long as we need it for the purpose we collected it for, or for as long as the law requires us to, whichever is longer. In practice:

InformationHow long we keep it
WhatsApp conversations and enquiry records where you did not proceed36 months from your last contact with us, after which they are deleted or anonymised.
Records of customers and completed installationsFor the duration of our contract with you, plus the warranty and maintenance period, plus 8 years, because company law requires us to keep books and records of our transactions.
Records of your consent and any withdrawal of consentFor as long as we hold the data that consent relates to, and for 7 years afterwards, as evidence that we had your permission.
Opt-out recordsIndefinitely, so that we can continue to honour your opt-out.
Website logs and technical records of processing12 months.

Where we are required by law to keep something for longer, we keep it for that longer period and use it for nothing else.

Your rights

You may request access to, correction or deletion of your personal data using the contact details below.

You also have the right to withdraw your consent at any time, as easily as you gave it. Withdrawing consent does not affect anything we did with your data before you withdrew it.

You may nominate another person to exercise these rights on your behalf if you are unable to do so.

If you are not satisfied with how we have handled a request or complaint, you may complain to the Data Protection Board of India.
