What this policy covers
This policy explains what the Dvaitam Solar mobile app (Android package and iOS bundle com.dvaitam.solar) collects, why, where it goes, how long we keep it and how you delete it. It covers the app only. Our website has its own privacy policy.
Dvaitam Ventures LLP ("Dvaitam", "we") is a solar and clean-energy engineering contractor in Jaipur, Rajasthan, India. We are the data fiduciary for everything described here. We are not an advertising or data business: nothing you give the app is sold, rented or used to build an advertising profile.
The app is built for adults in India who want a rooftop solar system, a panel cleaning or maintenance visit, or solar finance from a partner bank. Reading the home screen, the brand list and the price calculator asks nothing of you; the data described below is collected only when you book a service or use your profile.
Summary of our data practices
The table below is the same set of answers we give in the Google Play Data safety section and the App Store privacy label. The rest of this policy explains each row.
| Data | When it is collected | Why | Shared with |
|---|---|---|---|
| Device account identifier | Automatically, on first launch | To keep your bookings and profile together without a sign-in | No one |
| Name, mobile number, email (optional), city, state, PIN code | When you set your location, edit your profile or book a service | To prepare your quote, arrange the visit and call you about it | No one, unless you ask us to pass a finance enquiry to a partner bank |
| Site address and landmark | When you book a service | To send a surveyor or technician to the right roof | No one |
| Other contact people (name and mobile) you add to a booking | When you add them | So the site visit can be coordinated with them | No one |
| Electricity bill details (amount, period, units, DISCOM), roof and system preferences | When you use the calculator or book new solar | 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 |
| Photos, PDFs and videos you attach (electricity bill, 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 amount |
| Inverter brand, model, serial number and nickname | Only if you register an inverter | To identify your plant for future monitoring and service | No one |
| Support queries (subject and message) | When you write to us from the app | To answer you | No one |
| Referral code you enter or share | If you use the referral feature | To credit the person who referred you | Whoever you choose to share your code with |
| IP address, request time and app platform (server logs) | Automatically, with every request to our server | Security, abuse prevention and rate limiting | No one |
The app contains no analytics, advertising, crash-reporting, tracking or attribution software, requests no location, contacts, SMS or call-log access, runs nothing in the background and sends no push notifications.
Your device account — no sign-in, one identifier
The app has no login screen. The first time it opens, it asks our server for an account and receives a random access token, which it keeps in the device's secure store (Android Keystore or iOS Keychain). That token is the only thing that links this installation to your bookings. It is not an advertising identifier and it is not shared with any third party.
Because the account belongs to the device, an app that is uninstalled on Android loses the token and the next install starts a fresh, empty account. Your earlier bookings still exist on our side; contact us with your mobile number and we will tell you their status or delete them on request.
Until you type a name and mobile number — in your profile, in the location sheet or in the first booking — the account holds no personal information at all.
Information you give us
Everything in this section is collected only when you enter it, and each booking step shows you exactly what will be sent before you submit.
- Profile: your name, mobile number (Indian number, stored in international format), optional email address and address (house or plot, locality, city, state, PIN code).
- Location: city, state and PIN code, saved to the same profile so every booking form is pre-filled and so prices and subsidy slabs use the right state.
- Booking contacts: the name and mobile number of up to five people who should be contacted about the visit. When you add someone else, please make sure they are happy for us to call them about your booking.
- New solar: your electricity bill amount and billing period, estimated monthly units, DISCOM, roof and segment (home, housing society, factory or solar park), chosen panel type and brand, and whether you want finance.
- Cleaning and maintenance: the site address, the service you want, a description of the problem and, if you have one, the Dvaitam project the visit relates to.
- Solar finance: the partner bank you are interested in, the loan amount, tenure and the project it finances. We do not run credit checks and we are not a lender.
- Inverter registration: brand, model, serial number, a nickname and plant size.
- Support: the subject and text of queries you send us, and your replies.
- Referrals: a referral code you enter when booking, and your own code if you share it.
Files you attach: camera, photos and documents
Some booking steps let you attach an electricity bill (photo or PDF), a property-tax receipt and a short video of your roof. Every attachment is optional and nothing is read from your device unless you pick it.
On Android the app opens the system camera and the system photo and file pickers, which hand back only the item you choose. It therefore declares no camera, storage or media permission at all — the only permission in its manifest is internet access. On iOS the first use of the camera or photo library shows the standard Apple prompt, which you can decline.
Uploaded files are stored in a private area of our server that is never publicly reachable; the app and our staff platform fetch them through authenticated requests only. You can remove an attachment from the app until the booking is submitted, and deleting your account removes every file.
When you attach an electricity bill in the calculator, the image is also sent to an AI text-extraction service (the Anthropic API) so the bill amount, period and units can be pre-filled for you to confirm or correct. 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. If you would rather not have a bill scanned, type the figures instead — the result is the same.
How we use your information
- To size and price a solar system, estimate the PM Surya Ghar subsidy and show indicative EMIs. Every figure in the app is an estimate until a site survey confirms it.
- To arrange and carry out the survey, installation, cleaning, maintenance or finance enquiry you booked, and to contact you about it by phone, WhatsApp or email.
- To show you the status of your bookings, your documents, your referrals and your transactions inside the app.
- To answer your support queries.
- To keep the service secure: rate limiting, abuse prevention and fixing faults.
- To meet legal obligations, such as tax and accounting records for work we actually carry out.
Who we share information with
We do not sell personal information and we do not share it with advertisers or data brokers. It leaves our systems only in the cases below.
- Our hosting provider, which runs the server and database the app talks to. It stores data on our behalf under contract and does not use it for its own purposes.
- The AI text-extraction provider described above, for electricity-bill images only, when you attach a bill.
- A partner bank, 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.
- WhatsApp, Apple or Google, when you choose to open a chat, share your referral code or call us — those actions leave the app and are governed by those companies' own policies.
- Our own staff, who see bookings in the Dvaitam platform to plan and deliver the work, and who are bound by confidentiality.
- Government bodies or courts, only where the law requires it.
Government 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 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. Official information is always available from the portals above.
How we store and protect it
- All traffic between the app and our server is encrypted with HTTPS; the production app refuses plain-text connections.
- Your access token lives in the Android Keystore or iOS Keychain, not in ordinary app storage, and the app opts out of Android device backups.
- Drafts of bookings you have not submitted are kept on the device only, so you can finish them later; they are not sent to us until you submit.
- Uploaded files are stored privately and served only to the account that uploaded them and to our staff.
- The production app blocks screenshots and screen recording of its screens, so bill images and personal details are not captured by other apps.
- Access to the staff platform is limited to Dvaitam employees with a role that needs it, and every change to a booking is logged.
How long we keep it
- Your profile, bookings, uploads, queries, inverters and referral history: for as long as your account exists, so the app can show them to you.
- Server logs containing your IP address: for up to 90 days, for security.
- Records of a project that became a signed contract — the quotation, invoice and warranty details — are also held in our accounting records and kept for the period Indian tax and company law requires (up to eight years), even if you delete your app account.
- Backups of our database are overwritten on a rolling basis and deleted data is gone from them within 30 days.
Deleting your account and data
Open the app, go to Profile → "Delete my account & data" and confirm. Your profile, bookings, uploaded files, queries, inverters and referral history are deleted from our server immediately, and the app starts again with an empty account. You can also request deletion without the app at dvaitam.com/delete-account/.
The in-app deletion is complete and immediate; there is no waiting period and nothing you need to send us. The only thing we keep is what the previous section says the law obliges us to keep for work we actually carried out, and even then only in our accounting records, not in the app.
If you no longer have the app, or cannot open it, the web page linked above explains how to ask for the same deletion by email. We act on those requests within 30 days and confirm when it is done.
You can also delete individual attachments from an unsubmitted booking, delete unsubmitted drafts, remove a registered inverter and cancel a booking, all inside the app.
Permissions the app uses
- Android: INTERNET only. Photographs and videos go through the system camera app and files through the system picker, which need no permission of their own. The app declares no camera, storage, location, contacts, SMS, phone, microphone or advertising-ID permission.
- iOS: Camera and Photo Library, each requested by Apple's standard prompt the first time you choose to take or attach a photo or video. Nothing else.
- Opening WhatsApp, the phone dialler, the share sheet or dvaitam.com hands you to that app; nothing is read back.
What the app never does
- No analytics, measurement or crash-reporting software of any kind.
- No advertising, no advertising identifier, no device fingerprinting, no tracking across other apps or websites, no profiling.
- No access to your location, contacts, calendar, messages, call log or microphone.
- No background activity and no push notifications; the in-app notifications list is simply the status of your own bookings and queries, fetched when you open it.
- No selling, renting or trading of personal information with anyone, for any purpose.
Your rights
Under India's Digital Personal Data Protection Act, 2023, you have the right to know what personal data we hold about you, to have it corrected or updated, to have it erased, to withdraw consent you have given, and to nominate someone to exercise these rights for you. Most of this you can do yourself in the app: edit your profile, delete attachments, cancel bookings, or delete the whole account.
For anything else, email dvaitamventures@gmail.com or call +91 91193 17319; we respond within 30 days. If you are not satisfied with how we have handled a concern, you may complain to the Data Protection Board of India.
Children
The app is for adults arranging work on property they own or manage and is not directed at anyone under 18. We do not knowingly collect personal data from children; if you believe a child has given us data through the app, contact us and we will delete it.
Changes to this policy
If a future version of the app collects something new, requests a new permission, adds a third-party service or changes how long we keep data, this page is updated before that version is released and the date at the top changes. Material changes are described here rather than made silently, and the app always links to the current version from Profile → Privacy policy.
