Hisab is built to keep your business data private. This policy explains exactly what the app does and does not do with your information. In short: your invoices and customer records stay on your device, and the only thing sent to us is a short registration record identifying the business itself.
1. The short version
- Hisab works offline and has no sign-up, password or user account.
- Your invoices, customers, products and transactions are stored only in a database file on your own device. They are never uploaded.
- When you save your business profile, the app sends your business name and address to our registry so we know which businesses use the app. Nothing else is transmitted.
- Apart from that record, nothing leaves your device unless you personally choose to share it.
2. Information stored on your device
The app stores the information you enter so it can produce your invoices. This is held in a local database on your device and in your device's app preferences.
- Business profile: business name, address, GSTIN, PAN, bank details, logo and signature images.
- Customers and suppliers: names, addresses, GSTIN and contact details you enter.
- Products and services: descriptions, HSN/SAC codes, rates and tax rates.
- Transactions: invoices, quotations, payments and expenses.
- App preferences: your theme choice and invoice template settings.
3. Information we collect
The app has no analytics, no advertising, no tracking identifiers and no crash reporting. There is no sign-up, no password and no cloud backup of your records.
One record is sent to us. When you save your business profile, the app writes the following to our business registry so we have a record of the businesses using it:
- Your business name, legal name and address, as entered in the business profile.
- The app version and whether you are on Android or iOS.
- An anonymous identifier created by the app on this device. It is not your phone number, email or any account, and it is not linked to your identity.
3a. What is never sent
To save that record the app opens an anonymous session with Firebase, our hosting provider. This involves no email, password or personal detail.
Your invoices, quotations, customers, suppliers, products, payments, expenses, GSTIN, PAN, bank details, logo and signature images are never transmitted. They stay in the database file on your device.
The app also reads a small settings file from our servers to check whether an update is required. That is a download only and sends none of your information.
If this ever changes in a future version, this policy will be updated and the change will be described in the app's release notes before it takes effect.
4. Photos and files
The app asks for the camera only when you choose to photograph a business logo, a signature or a purchase bill, and for your photo library only when you pick one of those from it. You can decline either and still use every feature by choosing the other.
The image you pick is copied into the app's own storage and used solely to render your invoices and to show your saved bills. No other photo is read, and no image is uploaded anywhere.
File access is used only when you explicitly save a backup file or choose a backup file to restore.
5. Sharing — always your choice
Data leaves your device only when you deliberately act:
- Sharing or printing a PDF invoice hands the file to the app you pick (email, WhatsApp, a printer, cloud storage). What happens next is governed by that app's own privacy policy, not ours.
- Exporting a backup writes a JSON file to the location you choose. That file contains your full business data in readable form, so store it somewhere you trust.
6. Keeping your data safe
Your data is protected by your device's own security — its lock screen and its app sandboxing, which prevents other apps from reading Hisab's files.
Because there is no cloud copy, you are responsible for your own backups. If you lose or reset your device without an exported backup, the data cannot be recovered by us or by anyone else. We strongly recommend exporting a backup regularly.
7. Deleting your data
Settings contains a "Delete data" option that permanently erases every invoice, customer, product and setting from your device. Uninstalling the app also removes its entire database. Both are irreversible. As we hold no copy, there is nothing further to request from us.
Note that Indian GST law requires businesses to retain records for a statutory period. Deleting your data in the app does not relieve you of that obligation — keep your own records.
8. Children
Hisab is business software intended for use by adults operating a business. It is not directed at children, and we do not knowingly collect information from them.
9. Changes to this policy
If this policy changes, the "Last updated" date above will change and the revised policy will be published here and in the app. Continuing to use the app after an update means you accept it.
