1. Who this covers
This policy covers heartinz.com, our apps, and our products where they do not publish a policy of their own. Heartinz Technologies Private Limited decides how the information is used. Each product also has its own privacy page: NegoBill privacy.
2. What we collect and why
- When you contact us: your name, email, phone and message, to answer you.
- When you buy a subscription: your name, email, phone, business name, GSTIN and billing address, to make the GST invoice and run the account.
- When you use NegoBill: the data your business enters (bills, products, stock, customers, suppliers, payments). It belongs to your business; we store it to provide the service and never use it for anything else.
- When you use Charge Meter or Network Meter: nothing that identifies you. The readings are taken from the device and shown on the device. Each app’s Data safety section on Google Play lists what it collects and shares.
- On this website: standard server logs (IP address, browser, pages, time) to keep the site running and secure, and only the cookies the site needs to work.
We do not sell or rent personal information, and we do not send marketing you have not asked for.
3. Who we share it with
- Razorpay, our payment gateway: your name, email, phone, order number and amount, to take the payment; for a monthly plan, also the mandate reference and its status (active, paused, cancelled) so we know which debit paid which month. Card and UPI details are entered on Razorpay’s page and never reach us; we hold only the masked form Razorpay returns. Razorpay’s privacy policy.
- Google Cloud (Mumbai region, India), where NegoBill data is stored, and Google Play / Apple App Store, which deliver the apps.
- Authorities, when the law requires it.
Nobody else.
4. How long we keep it
Account and business data: for as long as the account exists, and 30 days after you delete it. Invoices and payment records: for the period tax law requires. Contact-form messages: until the matter is closed.
5. Your rights
You can see, correct and export your data from within the product, and delete your account yourself: NegoBill from Settings → Account (how); the apps through our data deletion page. Email us for anything you cannot do yourself.
6. Security
Data travels encrypted (HTTPS), is stored with access limited to the people who run the service, and is backed up. No system is perfect; if a breach affects you, we tell you.
7. Children
Our products are for businesses and adults. We do not knowingly collect information from children under 18.
