Delete your data

How to ask

Any one of these is enough. Please contact us from, or quote, the mobile number on your FilterXpert account — that number is how we know it is really you.

• Email [email protected] with the subject “Delete my data”.
• WhatsApp the word DELETE to us from your registered number.
• Call +91 90739 08901 and ask.
• Write to 27/56, Attapara Lane, Sinthi, Baranagar, Kolkata 700050.

How long we take

We acknowledge your request as soon as we see it and complete it within 30 days. If anything is going to take longer we will tell you why before the 30 days are up, not after.

What gets deleted

• Your name, phone number, email address and postal address, and the map pin for it.
• The record of the machines at your premises and their service history.
• Photographs taken during visits, and the signature you gave on the technician’s phone.
• The messages between us, on WhatsApp, SMS and email, including anything you sent us.
• Notes and internal ratings our staff recorded about your account.
• Your feedback, reviews and survey answers.
• Your customer portal sign-in, and any browser notification permission.

We also tell the companies that process data on our behalf — listed in the privacy policy — to do the same.

What we cannot delete, and why

Invoices, receipts and payment records. Indian tax law requires us to keep them for a set number of years, and that obligation outlives your request. We will delete them when the law allows, and not before. We say so here rather than promise a clean sweep and quietly keep them.

What you lose

Deleting your information ends the service relationship. Without your address and the history of your machine we cannot honour an AMC, process a warranty claim, or send a technician who knows what is already fitted. If you only want us to stop messaging you, ask for that instead — reply STOP on WhatsApp, and we will keep your service record but stop the reminders and offers.

If we get it wrong

Our Grievance Officer is the Head of Operations, Twinsons Water Technologies, at [email protected] or +91 90739 08901. If you are still not satisfied you may complain to the Data Protection Board of India. Your full rights are set out in the privacy policy.
