Website Privacy Policy
What Dvaitam does — and deliberately does not do — with your information on dvaitam.com, including the solar booking tool at dvaitam.com/book.
Who this policy covers
This policy explains how Dvaitam Ventures LLP ("Dvaitam", "we", "us") handles information about you on dvaitam.com: the public website, the solar booking tool at dvaitam.com/book and the staff platform at dvaitam.com/app. The Dvaitam Solar mobile app (com.dvaitam.solar) has its own privacy policy.
We are a solar and clean-energy engineering contractor in Jaipur, Rajasthan, and the data fiduciary for everything described here. We are not an advertising or data business: we collect what is needed to answer an enquiry, size and price a solar system and deliver a project, and nothing that exists only to be monetised.
The booking tool and the mobile app share one backend, so a booking made on the website and one made in the app are stored and handled the same way. Where this page and the app policy describe the same thing, they say the same thing.
The enquiry form, email, phone and WhatsApp
The enquiry form asks for your name, company, email address, phone number, the service you are interested in, your site location and a description of your project. Only the fields marked as required must be filled in.
The form does not post to our server. It is checked in your browser and then opens WhatsApp with your enquiry pre-filled as a message, which you send yourself. Your enquiry therefore reaches us through WhatsApp and is handled under WhatsApp's privacy policy as well as this one. If you would rather not use WhatsApp, email or call us using the details at the end of this page.
If you contact us by email, phone or WhatsApp without the form, we hold whatever you send us in that message — typically your name, contact details and the details of your project, along with any drawings, bills or site photographs you choose to attach.
The solar calculator on the website runs entirely in your browser. The bill amount and roof details you type are not sent to us unless you go on to make an enquiry or a booking.
The solar booking tool (dvaitam.com/book)
The booking tool lets you size and price a rooftop system, book a cleaning or maintenance visit and ask about solar finance. Browsing it, using the calculator and reading the brand list need no account. You sign in with your mobile number and a one-time code only when you book, upload a file or open your profile; the first successful code creates your account. There are no passwords.
Everything in the table below is collected only when you enter it, and each booking step shows what will be sent before you submit.
| Data | When | Why | Shared with |
|---|---|---|---|
| Mobile number (verified by one-time code) | When you sign in | To create and find your account and to call you about a booking | No one |
| Name, email (optional), address (house, locality, city, state, PIN) | When you edit your profile or book | To prepare your quote and arrange the visit | No one, unless you ask us to pass a finance enquiry to a partner bank |
| Site address, landmark and up to five contact people (name and mobile) | When you book | So the survey or visit reaches the right roof and person | No one |
| Electricity bill amount, period, units, DISCOM; roof and system preferences | Calculator and new-solar booking | To size and price the system and estimate subsidy | No one |
| Finance preferences (lender, loan amount, tenure) | Only if you choose solar finance | To show indicative EMIs and prepare a finance enquiry | A partner bank, only when you ask us to forward it |
| Files you attach: electricity bill (photo or PDF), property-tax receipt, roof video | Only when you attach them | To verify the bill and plan the installation | An AI text-extraction provider, for bill images only, to pre-fill the bill figures |
| Inverter brand, model, serial number, nickname | Only if you register an inverter | To identify your plant for service | No one |
| Support queries and replies; referral code entered or shared | When you use those features | To answer you; to credit the person who referred you | Whoever you share your code with |
A sign-in token and your unsubmitted booking drafts are kept in your browser's local storage so a reload does not lose your place. On a shared computer, sign out when you finish; it removes the token. Drafts are sent to us only when you submit.
Information collected automatically
- Server logs — our hosting provider records the IP address, browser user agent, requested page, referring page and timestamp of each request, and our API records the same for each call from the booking tool and the app. These exist for security, rate limiting and troubleshooting and are kept for up to 90 days.
- Cookies and local storage — the public website sets no cookies of its own. Google Tag Manager and Google Analytics, described next, set their own measurement cookies. The booking tool and the staff platform use browser local storage, not cookies, for the sign-in token and drafts.
- Analytics — the website loads Google Tag Manager (container GTM-WMT8FGPB), which delivers our Google Analytics 4 measurement tag. It reports aggregate usage: pages viewed, approximate region, device type, and events such as "enquiry form submitted" or "WhatsApp button clicked". Those events carry only the service and page involved — never a name, phone number, email, address or message text. The tags are loaded only after you first interact with the page (or after eight seconds), and they are not linked to Google advertising products.
- Fonts and images are served from our own site; no font request is made to Google.
How we use your information
- Responding to your enquiry, arranging a site survey and preparing a proposal or quotation.
- Sizing and pricing a solar system, estimating the PM Surya Ghar subsidy and showing indicative EMIs from partner banks. Every figure on the site is an estimate until a survey confirms it.
- Designing, procuring, building, commissioning, cleaning and maintaining the system you engage us for, and sharing what is necessary with the suppliers and subcontractors working on it.
- Showing you the status of your bookings, documents, referrals and transactions in the booking tool, and answering your support queries.
- Maintaining project records — calculations, test results, as-built drawings and correspondence — as evidence of what was delivered, and for warranty and after-sales support.
- Meeting legal, tax, statutory and subsidy-scheme obligations.
- Keeping the website and API secure, and understanding in aggregate which pages and services people find useful.
The basis on which we process your data
Under India's Digital Personal Data Protection Act, 2023, we process your personal data on the basis of the consent you give when you send an enquiry, create a booking-tool account or engage us for a project, and for the legitimate uses that Act permits — performing a contract with you and complying with the law. If you contact us from outside India, the equivalent grounds under your local law apply.
You can withdraw your consent at any time. Withdrawing it does not affect processing already carried out, and it may mean we can no longer progress an enquiry or support work already delivered.
Who we share information with
We do not sell, rent or trade personal information, and we do not share it for anyone else's advertising. It leaves our systems only in the cases below.
- WhatsApp (Meta) — when you send an enquiry through the form or a WhatsApp button, the message is transmitted and stored by WhatsApp under its own terms.
- Our hosting provider — which serves the website, runs the API and database behind the booking tool and the app, stores uploaded files privately, and keeps the server logs described above, all on our behalf under contract.
- Google — Google Tag Manager and Google Analytics receive the aggregate usage data described above. Google Play and the App Store distribute the mobile app and report aggregated install statistics to us under their own policies.
- An AI text-extraction provider (the Anthropic API) — when you attach an electricity bill in the booking tool or the app, the image is sent so the bill amount, period and units can be pre-filled for you to confirm. The provider processes the image only to return that result; under its commercial API terms it does not use the content to train its models. Type the figures instead if you prefer; the result is the same.
- Partner banks — only if you asked for solar finance and, after we have spoken to you, you ask us to forward your enquiry. We do not pass your details to any lender without telling you first.
- Suppliers, subcontractors and equipment vendors — limited to the details a specific project needs, such as a delivery address or a site contact.
- Government bodies, DISCOMs and scheme portals — where a subsidy application, grid connection or statutory approval requires it, and otherwise only where the law obliges us.
- Legal and professional advisers, auditors and insurers, under confidentiality.
Government subsidy information
Pages on this site explain the PM Surya Ghar: Muft Bijli Yojana rooftop solar subsidy and estimate what you may receive, using the slabs published at https://www.pmsuryaghar.gov.in and https://mnre.gov.in. The subsidy application is made by you on the official portal; we help you prepare it.
Dvaitam Ventures LLP is a private company. It is not a government body, is not affiliated with any government entity and does not represent one.
How long we keep it
- Enquiries that do not lead to a project: only as long as they are useful for follow-up, after which they are deleted.
- Booking-tool and app accounts — profile, bookings, uploads, queries, inverters and referral history: for as long as the account exists. Ask us to delete the account and it is gone within 30 days; in the mobile app you can delete it yourself instantly.
- Records of projects we deliver: for the life of the installation and for as long as tax, statutory, warranty and subsidy-scheme obligations require — up to eight years for accounting records under Indian law.
- Server and API logs containing your IP address: up to 90 days. Database backups are overwritten on a rolling basis and deleted data is gone from them within 30 days.
- Analytics data is held by Google for the retention period set in our Google Analytics property and is aggregate in any case.
How we protect it
- The website, the booking tool and the API are served only over HTTPS, so traffic between your device and our systems is encrypted in transit.
- Uploaded files are stored in a private area of our server that is never publicly reachable and are served only to the account that uploaded them and to our staff.
- Booking-tool sign-in uses a one-time code sent to your phone, with a short expiry, a limit on attempts and rate limiting by number and address. The resulting token is revocable and limited to your own data.
- The staff platform at /app is for Dvaitam employees only. Staff sign in with individual accounts, see only what their role allows, and every change they make to a booking is logged.
- We do not collect payment card details, bank credentials or government identity numbers through the website, the booking tool or the app. If a project needs such documents, they are collected through a separate, agreed channel — never through a web form.
- No system is perfectly secure. We take reasonable technical and organisational measures appropriate to the sensitivity of what we hold, and we limit access to the people who need it to do the work.
Your rights and how to exercise them
You can ask us at any time to tell you what personal data we hold about you and how it is used, to correct anything inaccurate or incomplete, to erase data we no longer need to keep, or to withdraw consent you have given. You may also nominate another person to exercise these rights for you in the event of death or incapacity.
To make a request, email dvaitamventures@gmail.com or call +91 91193 17319 with enough detail for us to find your records — for a booking-tool account, the mobile number you signed in with. We respond within 30 days. Deleting a booking-tool or app account is described step by step on our account deletion page. If you are not satisfied with how we have handled a privacy concern, you may raise it with the Data Protection Board of India.
Children
Our services are sold to businesses, institutions and property owners, and neither the website, the booking tool nor the app is directed at anyone under 18. We do not knowingly collect personal data from children. If you believe a child has sent us personal data, contact us and we will delete it.
Links to other sites
The website links out to third-party destinations — our social media profiles, WhatsApp, government subsidy portals, partner banks and manufacturer documentation. We are not responsible for the privacy practices of those sites, and we encourage you to read their policies before submitting anything to them.
Changes to this policy
We update this page when the website, the booking tool or our data practices change in a way that affects your privacy — a new third-party service, a new kind of data, a change to how long we keep it. The date at the top always reflects the current version, and material changes are described here rather than made silently.
