Privacy Policy: Hisaab
This policy explains what data the Android app Hisaab: Invoice & Khata(package com.brightbyte.hisaab), published by Bright Byte, collects and how it is used.
Your business records stay on your device
Hisaab is an invoicing and khata (customer credit) app. Everything you enter is stored only on your phone, in the app's private storage:
- your business details (name, owner name, phone, email, address, tax numbers, payment details, terms) and, if you add them, your logo and signature
- your customers' details that you type in (name, phone number, address, tax number)
- your items and prices, invoices, quotations, receipts, payments and khata entries
- your saved tax rates, discounts, terms, notes and invoice designs, and your settings
This data is not sent to us. The app works offline. Uninstalling the app or clearing its data removes it from the phone. If Android backup is turned on for your Google account, Android may include it in your device backup, which is handled by Google under its own policy.
You are responsible for having the right to keep your customers' details in the app, as you would be with a paper khata.
Sharing bills and reminders
When you tap WhatsApp, Share, Print or Remind, the app creates the PDF or message on your phone and opens the app you choose (for example WhatsApp) with it attached. Nothing is sent unless you send it yourself in that app, which handles it under its own policy. The app does not read your contacts or your messages.
Optional Google sign-in and cloud backup
Cloud backup is optional and off until you turn it on. If you choose Sign in with Google (in Backup & cloud, or when setting up the app on a new phone):
- Google sign-in shares your Google account's name, email address and account ID with the app through Firebase Authentication, so your backup belongs to your account only.
- When you back up (by hand, or automatically if you are a Pro user and keep auto-backup on), a copy of your Hisaab data, including your logo and signature images, is stored in Google Cloud Firestore under your account. Only you can read it; access rules allow each signed-in account to reach its own data only.
- The backup is used only to restore your data on this or another phone. We do not read, analyse, sell or share it.
- You can delete it at any time in the app: More > Backup & cloud > Delete cloud data. This deletes your cloud backup and your sign-in record. You can also sign out without deleting.
Backup files
You can also make a backup file and save or share it wherever you choose (for example Google Drive or WhatsApp). That file contains your Hisaab data and is handled by the place you save it to.
Data collected by third-party services
The app uses the following Google services. They may collect some data automatically:
| Service | Data | Purpose |
|---|---|---|
| Google AdMob (ads) | Advertising ID, IP address (used for approximate location), device and app information, ad interactions | Showing ads, measuring ad performance, preventing fraud |
| Google User Messaging Platform | Your ad consent choices | Asking for and storing consent where the law requires it |
| Firebase Authentication (only if you sign in) | Google account name, email address, account ID; device and app information used for security checks | Signing you in to your cloud backup |
| Google Cloud Firestore (only if you back up) | Your Hisaab backup (see above) | Storing and restoring your backup |
| Google Play Billing | Purchase history for Hisaab Pro | Processing purchases and restoring Pro |
| Google Play (asset delivery) | App version and device information | Downloading the extra invoice fonts when you choose a design that uses them |
This data is sent over encrypted (HTTPS) connections. Google processes it under its own privacy policy: policies.google.com/privacy
Your bills, customers and khata are never sent to the ads service.
Ads and your choices
- In the EEA, the UK and Switzerland, the app asks for your consent before personalised ads are shown (Google UMP). You can change your choice at any time in More > Settings > Privacy.
- You can reset or delete your advertising ID in your device settings: Settings > Google > Ads (or Settings > Privacy > Ads, depending on your device).
- Ads shown in the app are limited to content suitable for general audiences.
- Video ads play only when you choose to watch one (for example, to use a Pro design for one PDF).
- Hisaab Pro removes all ads.
Your country
To set the right currency, tax number names and phone code, the app reads your SIM or network country (for example "PK") on your phone when you first set it up. This stays on your phone; you can change the country in Settings.
Permissions
The app does not ask for any runtime permission. Your logo, signature photo and backup files are picked with Android's own photo and file pickers, so the app sees only the item you choose. It uses only normal permissions that Android grants at install:
- Internet and network state: to load ads, sign in, back up to the cloud, talk to Google Play for purchases and download the font pack
- Advertising ID (AD_ID) and Android ad services: used by the ads SDK
- Google Play Billing: for Hisaab Pro
- Foreground service (data sync): used by Google Play to finish downloading the font pack you asked for
Purchases
Hisaab Pro (monthly, yearly or lifetime) is handled entirely by Google Play. We never see your card or payment details. Subscriptions can be cancelled at any time in Google Play.
Children
The app is made for business use and is not directed at children under 13. We do not knowingly collect personal data from children.
Data deletion
- On your phone: uninstall the app or clear its data in Android settings.
- In the cloud: in the app, More > Backup & cloud > Delete cloud data deletes your backup and your sign-in record. If you no longer have the app, write to us from the email of your Google account and we will delete them within 30 days.
Changes
We may update this policy. The “Last updated” date above shows the latest version.
