Munshi: Invoice/Bill Maker — Privacy Policy

Last updated: 10 November 2026

Munshi ("the app") helps small businesses in India make invoices, bills, quotations and receipts. It comes as an Android phone app and, for Munshi Pro, as a Windows app ("Munshi for Windows"). Munshi is an independent app. It is not a government app and is not affiliated with any government body. This policy explains what happens to your information.

What stays on your phone or PC

Everything you enter — business details, GSTIN, customers, items, invoices, payments, logo and signature — is stored on your phone, or on your PC if you use Munshi for Windows. We do not run any server that stores your business data, and we cannot see it. The only small service we run is the Windows key service described below.

Optional backup to your own Google Drive

If you sign in with Google in the Backup screen, Munshi saves an encrypted-in-transit copy of your data to the hidden "App data" folder of your own Google Drive. Only Munshi can open that folder, and we have no access to it. Munshi keeps one backup per day for the last 7 days and deletes older ones. The only permission requested is drive.appdata. Your Google account email is stored on your phone to remember which account is linked. You can stop backups and delete the backup files from your Google account at any time.

Munshi's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements. Munshi uses your Google Drive only to save and restore your own backup. It does not read any other file, does not share this data, and does not use it for advertising.

Using Munshi on a Windows PC (Munshi Pro)

Munshi for Windows is part of Munshi Pro. The phone and the PC share your data through the same hidden app folder in your own Google Drive, and only one of them uses the data at a time.

• Signing in to Google on the PC. The Windows app opens your web browser so you can sign in to Google. It asks for the same single permission, drive.appdata. The sign-in token is kept on your PC, scrambled with a key tied to that PC. It is removed when you hand the data back to your phone or sign out.
• The hand-over note. When you switch between the phone and the PC, Munshi saves a small note in the same hidden folder. It holds which kind of device owns the data, that device's name (for example your PC's name), a random install ID, the time, and the number of documents. It holds no invoice details.
• Local copy. The PC keeps your data in a file in your Windows user folder (%APPDATA%\Munshi) and a few recent copies there.
• The key service. To give you a Windows key, the Android app sends your Google Play purchase token to a small key service that we run on Google Apps Script. The service asks Google Play whether the purchase is real and then stores in a private Google Sheet: the key, the plan, the purchase token, the status, the times it was issued and checked, and, once you activate it, a random PC ID and your PC's name. It is used only to give you the key, to allow one PC per key, and to switch the key off after a refund or when a plan ends. The Windows app contacts the key service when you activate and about once a day. We do not store your invoices, customers, name, email or phone number in the key service.

Payments

Munshi Pro can be bought as a one-time lifetime purchase or as a monthly subscription. Both are handled entirely by Google Play. We do not receive or store your card or UPI details. Munshi only asks Google Play whether your account owns Pro or has an active subscription.

The UPI QR code shown while billing is created on your phone from the UPI ID you entered. Munshi never sees or confirms the payment; you mark it as received yourself.

Offers and messages to your customers

Munshi Pro lets you send festival wishes and offers to your own customers. You write or choose the message, you choose the customers, and you tap Send in WhatsApp for every message. Munshi never sends a message by itself, never sends from our servers, and never sends to anyone you have not confirmed as a WhatsApp contact. A customer can be marked "Do not send offers", and Munshi will then leave them out. Your customer list, messages and any poster you pick stay on your phone. A poster is copied only to your phone's temporary storage so WhatsApp can open it.

What we do not do

No ads. No analytics or tracking. No selling or sharing of data. No login or account with us.

Permissions

• Internet: only for Google Drive backup, Google Play purchase checks, and (Windows) the key service and Google sign-in.
• Camera is used only through Google's code scanner when you scan a barcode or an invoice QR; Munshi does not keep the images.

Sharing

Invoices, reports and offers leave your phone only when you tap Share, Print or Send and choose where to send them.

Children

Munshi is a business tool and is not directed to children.

Deleting your data

Uninstalling the app removes the data on your phone. On a PC, uninstall Munshi for Windows and delete the folder %APPDATA%\Munshi. To remove cloud backups, delete the app's data in Google Drive (Settings > Manage apps > Munshi > Delete hidden app data) or write to us. To have your Windows key record removed, write to us from the email you bought Pro with and tell us the key.
