1. Who we are
Heartinz Technologies Private Limited (“Heartinz”, “we”) is a software company registered in India, at 111 R G St, Coimbatore, Tamil Nadu 641001. These terms cover this website and everything we sell. By using the website, buying from us or creating an account in one of our products, you accept them.
2. What we sell
- NegoBill (negobill.com): billing, stock and customer-dues software for retail shops in India, sold as a yearly subscription on the web, iPhone and Android. NegoBill’s own pages state its product rules and apply together with these terms: Terms, Privacy, Refund policy, Cancellation policy, Delete your account.
- Charge Meter and Network Meter: free Android apps on Google Play. They are provided as they are; their readings are estimates made by the device.
- Software services: custom development, delivered under a written quote that sets the scope, price, schedule and ownership.
3. Prices and payment
Prices are in Indian Rupees; subscription prices include GST. See Pricing. A subscription is paid either yearly, as a one-time payment for the year, or monthly, where a monthly plan is offered, through Razorpay on the product’s own website; your card and bank details are entered on Razorpay’s secure page and never pass through us. A GST invoice is issued in Heartinz’s name for every payment, and a plan is switched on only after the payment is confirmed. A running period is never repriced.
Monthly plans and UPI Autopay. A monthly plan is paid by an automatic mandate — UPI Autopay, or a saved card — that you authorise once in your UPI app or bank. Before you authorise, you see the plan, the amount, the frequency (monthly) and the first debit date. Each month the amount is debited on the due date; your UPI app or bank notifies you before the debit as NPCI rules require. If a debit fails, we retry and tell you; the plan stays open for 7 days of grace and then locks until a payment goes through. You can pause or cancel the mandate at any time from Billing & Plans or from your UPI app or bank; the month already paid runs to its end and nothing more is debited. A change to the monthly price needs your fresh consent; we never raise the mandate amount on our own.
4. Cancellation, refunds and delivery
Software is delivered online the moment payment is confirmed; nothing is shipped. A yearly subscription runs for a year and does not renew by itself, so not renewing is the cancellation; a monthly subscription renews by its mandate until you cancel the mandate. The first yearly payment for a plan can be refunded within 15 days less a ₹199 processing charge, and the first monthly debit in full within 7 days; renewals, later monthly debits, add-ons and promotional purchases are not refunded; mistaken or duplicate payments are refunded in full within 7 to 10 working days. Full details: Refund Policy, Cancellation Policy, Shipping & Delivery.
5. Your account and your data
Keep your login private and give staff only the access they need. Use our products for your own lawful business; do not copy, resell, reverse engineer or disrupt them. Data you enter into a product belongs to you; how we handle personal information is in our Privacy Policy, and each product lets you delete your account and its data.
6. Our responsibility
We aim to keep our products available at all times, with planned maintenance announced in the product, and we support you by email and phone on working days. Our products record what you enter; the correctness of your invoices, taxes and business decisions stays with you. To the extent Indian law allows, our liability for any claim is limited to what you paid us in the twelve months before it.
7. Law and contact
These terms are governed by the laws of India, with the courts of Coimbatore, Tamil Nadu having jurisdiction. Questions and complaints: support@heartinz.com or +91 770 8343 523 (Mon–Sat, 10am–6pm IST). Grievance Officer: Maria Kiran, Director and CEO, same address and email. We may update these terms; the date at the top says when, and a change that affects a running subscription is announced in the product first.
