Privacy policy
Last updated: 4 November 2026. This policy covers Gayatri Calculator for Android (com.navarth.gayatricalc, and the earlier version com.bridginex.gayatri.calc), published by VUMP App solution.
In short: your bills, products, customers and areas are saved on your phone. They are copied to our server only if you accept the notice in the app. You can use the app without accepting, and you can ask us to delete your data at any time.
What is saved on your phone
The app saves your shop details, products, customers, areas and bills on your phone so it can work without the internet. It stays on your phone, even if data is also copied to our server. If Google backup is on, Android may also include it in your own Google backup.
What we collect if you accept the notice
The app shows a notice before anything is uploaded. If you tap Accept, the app copies this to our server:
| Information | What it includes |
|---|---|
| Shop details | Shop name, address, phone number, GST number and currency |
| Products and areas | Product names, prices and the areas you add |
| Customers | The names and phone numbers you enter for your customers |
| Bills | Items, quantities, prices, totals, dates, area and customer on each bill |
| Device details | Phone make and model, Android version, app version and language |
| Account ID | A random ID created for you, so your data can be kept together and restored |
| Google account | Your Google email and name, only if you choose to protect your data with Google |
| Notification ID | An ID from Firebase Cloud Messaging, used to send notifications to your phone |
If you tap Decline, none of this is uploaded and you can keep using the app on your phone.
If you send feedback
If you use Send feedback in the app, we receive your message, any phone number or email you add, your app version and your phone model. This works even if you declined the notice. If backup is on, we can see which account sent it. We use it only to fix problems, improve the app and reply to you. Feedback is deleted with your account, or when you ask us.
If you signed up in the earlier version
The earlier version of the app (com.bridginex.gayatri.calc) let you create an account with a username, email address, phone number and password. If you did, we keep those details, with your password stored only as a scrambled hash, not as readable text. The current app has no sign-up or login.
Why we use it
- To keep a copy of your data and restore it if you change your phone
- To count how many people use the app and fix problems
- To help you when you contact us
- To send notifications about the app, if you allow them
The publisher of the app can see the uploaded information in a private admin panel, including your shop, products, customers and bills. We do not sell your information.
Your customers' details
You choose what you enter about your customers. Enter only what you need for billing, and make sure your customers are comfortable with you keeping those details.
Companies that help us run the app
| Company | What it does |
|---|---|
| Render | Runs our server |
| Neon | Stores our database |
| Google Firebase | Delivers notifications and confirms your Google account |
These companies may store information outside India. We share information only as needed to run the app, or if the law requires it.
What we do not collect
- We do not read your phone's contacts, photos or location.
- The app does not show ads today. If we add ads, we will update this policy first.
How we protect your information
Information travels between the app and our server over an encrypted connection, and access to the admin panel is restricted. No system is completely secure, so keep your phone locked.
How long we keep it
We keep uploaded information until you ask us to delete it. After your request, we delete it within 30 days. See how to delete your account and data.
Your choices
- You can decline the notice and use the app on your phone only.
- You can turn backup off or on in My shop, then My account. Turning it off stops new uploads, and the copy on our server stays until you delete your account.
- You can turn off notifications in your phone's settings.
- You can ask us for a copy of your data, or ask us to correct or delete it.
Children
The app is made for shop owners. It is not meant for children under 13, and we do not knowingly collect their information.
Changes to this policy
If this policy changes, we will update this page and the date at the top. If we start collecting something new, the app will tell you first.
