01Who we are
Sensor Home Automation (“Sensor”, “we”, “us”) designs, installs and services gate automation, home automation and security systems. Our head office is at No.55, P H Road, Nerkundram, Chennai 600107, and our branch is at D.No.88/48, Veeranam Main Road, Ponnamapettai, Salem 636001, Tamil Nadu.
This policy explains what personal details we collect when you use www.sensorhomeautomation.in, contact us on WhatsApp or by phone, or become our customer — and what we do with them. We are the “data fiduciary” for these details under India’s Digital Personal Data Protection Act, 2023.
02What we collect
What you give us. When you fill in an enquiry or support form, message us on WhatsApp, call or email us: your name, mobile number, email address (optional), city or district, the services you are interested in, your property type and anything you write in the message. For a site visit, quotation or installation we may also note your address and details of the site.
How you found us. When you first visit, your browser remembers how you arrived (for example a Google search, an advert, Instagram or a WhatsApp link), the page you landed on and any campaign tags in the link. This stays in your browser for up to 90 days and is sent to us only if you submit an enquiry, so we know which of our adverts and pages are useful.
Technical details. Like every website, our hosting server records your IP address, browser type and the pages requested, for security and to keep the site running. Our enquiry form also uses your IP address briefly to stop spam.
Website analytics (only if switched on). If we turn on Google Analytics or the Meta Pixel, they record which pages are visited and actions such as tapping “Call” or “WhatsApp”, using cookies. We never send your name, phone number or message to these tools.
We do not knowingly collect details from children, and we do not ask for sensitive information such as financial account numbers through the website.
03How we use your details
- to reply to your enquiry, call you back and arrange a site visit;
- to prepare quotations, carry out installation and provide service and warranty support;
- to send you updates about work you have asked for (for example visit timings or service reminders);
- to understand which pages and adverts bring enquiries, and to improve the website;
- to keep our website and systems secure and prevent misuse;
- to meet our legal, tax and accounting obligations.
04Your consent
We use the details you submit because you agree to it when you tick the consent box on our forms or contact us directly. You can withdraw your consent at any time by writing to support@sensorhomeautomation.in or messaging us on WhatsApp. After that we will stop contacting you about new offers, though we may keep records we are required to keep by law or that are needed for an ongoing installation or warranty.
We will only send you promotional messages if you have agreed to receive them, and you can ask us to stop at any time.
06Cookies and browser storage
Our website stores a few small items in your browser. You can clear them at any time from your browser settings.
| What | Why | How long |
|---|---|---|
| How you found us (first visit and this visit) | Sent with your enquiry so we know which pages and adverts work | 90 days / this visit |
| 3D experience settings (tips seen, language, quote picks) | So the walk-through remembers your choices | Until you clear it |
| Google Analytics / Meta Pixel cookies (only if switched on) | Counting visits and actions such as calls and WhatsApp taps | Up to 2 years, as set by Google / Meta |
07How long we keep them
We keep enquiry details for as long as we need them to respond and follow up, and customer records (quotations, invoices, installation and warranty details) for as long as the warranty and service relationship lasts and as required by tax and accounting law. When details are no longer needed we delete them or make them anonymous. You can ask us to delete your enquiry earlier — see “Your rights”.
08How we protect them
Our website is served over an encrypted (HTTPS) connection, enquiry records are kept outside the public part of our web server, and only staff who need your details can see them. No system is perfectly secure, but we take reasonable steps to protect your details, and if a breach affecting you happens we will inform you and the authorities as the law requires.
09Your rights
You can ask us to:
- tell you what personal details we hold about you and how we use them;
- correct or update details that are wrong or incomplete;
- delete your details, unless we must keep them by law or for an ongoing contract or warranty;
- stop using your details for a purpose you consented to.
