DrillRig — Borewell Billing & Accounts · Last updated: 15 November 2026

In short: you sign in with Google to use DrillRig. Your bills and customer details are saved on your phone and in your business's cloud account, so they are backed up and your other phones can use them. The DrillRig team can see this data to run and support the service; every time we open it, it is recorded. We do not sell your data, show ads, or use tracking or analytics.

1. What DrillRig stores

Business data you type in: your company profile (name, phone numbers, address, logo, GSTIN, UPI ID), rates, customers (name, mobile number, village/site), bills, quotations, payments and notes.
Your Google account: your name, email address and profile picture, which Google shares with us when you choose "Continue with Google". Signing in is required to use the app.

We do not ask for, and do not store, your Google password, contacts, location, or any other Google data.

2. Where it is stored

On your phone: everything is saved in your browser's storage on your device, so the app works offline.
In the cloud: your business data is copied to a database run by Supabase, hosted in Mumbai, India. Only the people in your company account can read it in the app. It is sent over encrypted (HTTPS) connections.
What the DrillRig team can see: to run the service, give support, handle subscriptions and find problems, the DrillRig team can see everything stored in your business's cloud account: account details (name, email, business name, staff and their roles, rigs, subscription dates), totals (bills, feet drilled, amounts billed, received and due), and your bills and customers (names, mobile numbers, villages, amounts and payments). This access is limited to the DrillRig team, is read-only, and every time we open a business's report, bills or customers it is recorded in our admin log. We never share it with anyone else or contact your customers.

3. How it is used

Your data is used to run the app for you (calculate and save bills, show customer dues, share receipts, keep your phones in sync and backed up) and to support and improve the service (for example, checking a bill you ask us about, or seeing which features are used). We do not use it for advertising and do not sell or rent it to anyone.

4. Services the app uses

Google Sign-In — to sign you in (Google Privacy Policy).
Supabase — cloud database and sign-in.
GitHub Pages — hosts the app's web files.
Public code libraries (unpkg.com, cdnjs.cloudflare.com, Google Fonts) — load icons, fonts and the PDF/image export tools. Like any website, these servers can see your IP address when the files are downloaded.
WhatsApp — when you tap "Share on WhatsApp", the app opens WhatsApp with the message ready. DrillRig never sends messages by itself.

5. Your choices

Sign-in is required: DrillRig needs a Google sign-in so your data is backed up in your account. If you do not want your data in the cloud, please do not use DrillRig.
Download your data: Settings → Backup gives you a full copy as a file at any time.
Delete your data: delete bills or customers in the app, or clear the app's site data on your phone. To delete your cloud account and all its data, contact us (below) from your signed-in email address and we will delete it within 30 days.
Remove Google access: you can disconnect DrillRig at myaccount.google.com/permissions.

6. Customer details you enter

You are responsible for having your customers' permission to store their names and phone numbers and to message them. DrillRig only keeps these details for your business use as described above.

7. Children

DrillRig is a business tool and is not meant for children under 18.

8. Changes

If this policy changes, we will update the date at the top of this page.
