Terms & Conditions
What you agree to when you use the Dvaitam Solar app or the booking tool: how bookings, estimates, subsidy help and finance work, and which documents and details we collect, why, and with your consent.
1. These terms and your agreement to them
These Terms & Conditions govern the Dvaitam Solar mobile app (com.dvaitam.solar) and the booking tool at dvaitam.com/book (together, "the app"), both operated by Dvaitam Ventures LLP ("Dvaitam", "we", "us"). By installing or using the app, and again each time you tap "Confirm booking" or "Submit", you agree to these terms and to the collection and use of your information described in section 5 and in our privacy policy.
If you do not agree, do not use the app; you can still contact us by phone, WhatsApp or email and nothing in these terms applies to that conversation beyond our privacy policy.
You must be at least 18 years old and, when you book work on a property, either own it or have the owner's authority to arrange the work.
2. Who we are
Dvaitam Ventures LLP is a solar and clean-energy engineering contractor registered in Jaipur, Rajasthan, India, at P.No. L-170, Ganesh Vihar, Nangal Purohitan Road, Rajawas, Sikar Road, Jaipur, Rajasthan 303704. We design, supply, install, clean and maintain rooftop solar systems and help customers arrange finance and subsidy applications for them.
We are a private company. We are not a government body, we are not affiliated with any government entity and we do not represent one.
3. What the app does, and what it does not
- It estimates the size, price, subsidy, savings and EMI of a rooftop solar system from the figures you enter. Every number it shows is an indicative estimate until our engineer has surveyed the roof and we have issued a written quotation. An estimate is not an offer and not a price we are bound by.
- It lets you book a site survey for a new system, a cleaning visit, a maintenance visit or a finance enquiry. A booking is a request. It becomes a contract only when we confirm it and you accept our written quotation.
- It shows the status of your bookings, your documents, your referral code and any support replies.
- It takes no payment. We never ask for card numbers, bank credentials or government identity numbers through the app; if a project needs such documents, we collect them through a separate, agreed channel.
4. Your account
The mobile app creates an account for your device the first time it opens, without a sign-in, and keeps its access token in the device's secure store. The booking tool on the website signs you in with your mobile number and a one-time code. In both cases the account is personal to you: keep your device locked and do not let others book in your name.
You can delete the account and everything under it at any time from Profile → "Delete my account & data", or by following the account deletion page on our website. We may suspend an account that is used to make false bookings, to upload unlawful content or to interfere with the service.
5. Information and documents we collect, and your consent
To size a system, prepare a quotation and carry out a visit we need certain details from you. This section lists them, says why we ask, and records what you consent to when you submit. It is a summary of our privacy policy, which has the full detail and prevails if the two differ.
| What | Why we need it | How it is used |
|---|---|---|
| Your name and mobile number | To identify your booking and call you about it | Contact for the survey, quotation and visit; shown to our engineer |
| Email address (optional) | To send you the quotation and documents | Correspondence about your booking only |
| Site address, landmark and PIN code | To send the surveyor or technician to the right roof, and to apply the right state's prices and subsidy slabs | Scheduling the visit; subsidy and DISCOM lookup |
| Other contact people you add (name, mobile) | So the visit can be coordinated when you are not available | Called only about this booking |
| Electricity bill figures: amount, period, units, DISCOM | To size the system and estimate savings | Sizing and pricing; part of your quotation |
| Electricity bill photo or PDF, property-tax (Vera) receipt image, roof video | To verify the bill, confirm ownership for subsidy paperwork and plan the installation | Reviewed by our engineer; a bill image may be read by an automated text-extraction service to pre-fill the figures for you to confirm |
| System and roof preferences (segment, panel type and brand, size) | To quote the system you actually want | Quotation |
| Finance preferences (lender, loan amount, tenure) | To show indicative EMIs and prepare a finance enquiry | Shared with a partner bank only when you ask us to forward it |
| Inverter brand, model and serial number | To identify your plant for service | Service records |
| Support messages and referral codes | To answer you and credit referrals | Support and referral records |
Everything in this table is entered by you, in a step that shows it before you submit. Nothing is read from your device without your action: photos and files come only through the camera or picker you choose.
How it is stored and protected
Your details and files are stored on Dvaitam's own server with our hosting provider in a database and a private file area that are not publicly reachable. Traffic between the app and the server is encrypted (HTTPS only). Files are served only to your account and to Dvaitam staff whose role needs them, and every staff change to a booking is logged. The production app blocks screenshots and screen recording of its screens, keeps its access token in the device's secure store and opts out of device backups.
How long we keep it
For as long as your account exists. If you delete the account, your profile, bookings, files, queries, inverters and referral history are deleted immediately. Records of a project that became a signed contract are also held in our accounting records for the period Indian tax and company law requires (up to eight years). Server logs are kept for up to 90 days and backups purge deleted data within 30 days.
Your consent, and withdrawing it
By submitting a booking you consent to Dvaitam collecting the information above for the purposes stated, to its being seen by the staff and the service providers named in our privacy policy, and to being contacted by phone, WhatsApp or email about the booking. You confirm that the details are accurate, that any bill or receipt you upload relates to the property you are booking for, and that anyone whose number you add has agreed to be contacted about it.
You can withdraw consent at any time by cancelling the booking in the app, deleting an attachment before submission, deleting your account, or emailing us. Withdrawal stops future use; it does not undo work already done or remove records we must keep by law.
6. Bookings, surveys, quotations and cancellation
- After you book, we call to confirm a survey or visit time. There is no charge for a new-solar survey. Cleaning and maintenance visits are quoted after we have seen the site photos or spoken to you; we tell you the price before the visit.
- A written quotation follows the survey. It states the price, what is included, the panels and inverter offered, the timeline and the warranty, and it is valid for the period printed on it. The contract is formed when you accept that quotation, not when you book in the app.
- You can cancel a booking in the app at any time before we confirm a visit, at no cost. After a visit is confirmed, let us know as early as you can; if a technician has already travelled to a site for a cancelled cleaning or maintenance visit, we may charge the visit fee quoted to you.
- We may decline or cancel a booking where the site is unsuitable, outside our service area, or the details given were inaccurate. We tell you why.
7. Subsidy information
The app explains the PM Surya Ghar: Muft Bijli Yojana rooftop solar subsidy and estimates what you may receive using the slabs published at https://www.pmsuryaghar.gov.in and https://mnre.gov.in. The application is made by you on the official portal; we help you prepare and submit it. The subsidy is granted and paid by the Government, not by Dvaitam, and eligibility and amounts are decided by the scheme's rules, which can change. Dvaitam does not represent any government entity.
8. Solar finance
Dvaitam is not a lender and does not provide loans. The finance section shows indicative interest rates and EMIs from partner banks so you can compare options; the bank sets the actual rate, decides whether to lend and runs any credit check under its own terms. We forward your enquiry to a bank only after speaking to you and only when you ask us to. Nothing in the app is financial advice.
9. Your responsibilities
- Give accurate details, and update them if they change before the visit.
- Upload only documents that relate to the property you are booking for and that you are entitled to share.
- Add other people's contact numbers only with their agreement.
- Do not use the app to make bookings you do not intend to keep, to probe or overload our systems, to upload unlawful or harmful content, or to copy or resell the app or its content.
10. Content and intellectual property
The app, its design, text, calculations, images and the Dvaitam name and mark belong to Dvaitam or its licensors. Manufacturer logos shown in the panel-brand list belong to those manufacturers and appear only to identify the verified module catalog. You may use the app for your own booking and nothing else; you keep ownership of the documents and photos you upload and grant us permission to use them for your booking.
11. Availability and changes
We aim to keep the app available but do not promise uninterrupted service; it depends on your connection and on our hosting provider. We may change, suspend or withdraw features, prices shown as indicative, lender lists and the panel catalog at any time. We will update these terms when the app or our practices change, move the date at the top, and the app always links to the current version.
12. Liability
Estimates in the app are produced from the figures you enter and from published tariffs, yields and subsidy slabs; they are a guide, and we are not liable for decisions you take on an estimate before a survey and written quotation. For work we carry out, our liability is as set out in the quotation and the warranty, and in any case is limited to the amount you paid us for that work, except where Indian law does not allow such a limit — for example for death, personal injury, fraud or rights under the Consumer Protection Act, 2019, which these terms do not reduce.
13. Governing law and disputes
These terms are governed by the laws of India. We would rather resolve any disagreement by talking to you first; write to the address below. Failing that, the courts at Jaipur, Rajasthan have jurisdiction, without prejudice to your right to approach a consumer forum under the Consumer Protection Act, 2019.
14. Contact
Questions about these terms, a booking or your data: dvaitamventures@gmail.com or +91 91193 17319. Our privacy policy explains your rights over your data; our account deletion page explains how to remove everything.
