Privacy Policy

Effective 1 November 2026 · Trinevia Technologies Private Limited

In short: we don't have a database, and your bills never reach our servers.

Everything you type into Trinevia Billing, including your business details, customers, items and bills, is saved only on your own phone or computer. We cannot see it, and there is no account to sign up for.

1. What you enter, and where it is kept

When you use Trinevia Billing you may enter your business name, address, GST/VAT number, PAN, phone and email, logo, signature, bank and UPI details, your customers' details, items, prices and bills.

All of this is stored only on your device: in your browser's local storage on the website, or in the app's own folder on your computer if you use the Windows app. It is not sent to us or to any server of ours. We do not run a database.

  • If you clear your browser data, uninstall the app, or use a different browser or device, these details will not be there. We cannot recover them for you.
  • To keep a copy of a bill, download its PDF, or use Settings → Export invoice to save it as a file you can Import again later.
  • Anyone who can use your device and browser can open your saved bills. Protect your device with a screen lock.

2. PDFs, printing and sharing

PDFs, images and prints are created on your device. When you share a bill on WhatsApp, email or another app, it is sent by that app under its own privacy policy, not by us.

3. Free tools

Our free tools, such as the GST calculator and the amount in words converter, work entirely in your browser. The numbers you type are not sent to us and are not saved, not even on your device. They are gone when you close the page.

4. What we receive automatically

Like every website, some basic technical information reaches the companies that deliver the site:

  • Hosting (Vercel): our site is served by Vercel. To deliver pages, Vercel processes standard request data such as your IP address, browser type and the page requested, under its own privacy policy.
  • Visitor statistics (Vercel Web Analytics), only if you allow it: when you click Accept on the privacy banner, we count page views to understand which pages are useful. This is anonymous, aggregated and does not use cookies, and it never includes anything you type into the app. If you click Decline, it does not run. You can change your choice any time with Cookie settings at the bottom of every page.
  • Country pre-fill: on your first visit, the country shown on the setup screen is suggested from your approximate location (based on your IP address, provided by our host). It is used once to pre-select the country and is not stored by us. You can change it at any time.

5. What we do not do

  • No accounts, logins or passwords.
  • No database of your business, customers or bills.
  • No selling, renting or sharing of your information.
  • No cookies at all: no advertising, tracking or analytics cookies. Your privacy choice and your bills are kept in your browser's own storage on your device.

6. Offline use

If you install Trinevia Billing on your phone or computer, your device keeps a copy of the app's files so it works without internet. This copy contains the app itself, not your data from anyone else.

7. Children

Trinevia Billing is a business tool and is not directed at children.

8. Changes to this policy

If we ever add accounts, cloud backup or sync, we will update this policy before that feature goes live, and we will ask for your permission before any of your data leaves your device. The date at the top shows when this policy last changed.
