1Information stored on your device
The following is written to a private database on your phone and never leaves it:
- Your shop profile (business name, mobile number, TIN/BIN)
- Customers and suppliers (names, phone numbers)
- The credit ledger (বাকির খাতা) — amounts owed and paid
- Sales, purchases, returns, and receipts
- Cash book entries and day-open/day-close records
- Stock, products, prices, and product photos
- Loyalty points, reminders, and app settings
This data is protected by Android's app sandbox, which prevents other apps from reading it. You can add a PIN lock in Settings for extra protection.
Deleting the app removes this database from your phone. Because we never receive a copy, deletion is complete and immediate — there is nothing for you to request from us.
2Information we collect
None. Dokan has no user accounts, no sign-in, no cloud sync, and no backend server. The app makes no network requests in normal use.
We do not collect your name, email address, phone number, location, device identifiers, or usage statistics.
3Contacts
If you choose to add a customer from your phone contacts, Dokan asks for permission to read your contacts so it can show you a list to pick from.
- Your contacts are read on your device only, to display that list.
- Only the name and phone number of the contact you select are saved into Dokan's local database on your phone.
- Your contact list is never uploaded, transmitted, or shared with us or anyone else.
You can decline this permission and still use the app fully — you would simply type customer details in by hand.
5Advertising and analytics
Dokan contains no advertising, no analytics, no crash reporting, and no tracking libraries of any kind. We do not profile you, and we have no data to sell.
6Permissions and why they are used
| Permission | Why |
|---|---|
| Camera | Scan barcodes and take product photos |
| Contacts | Let you pick a customer from your phone contacts (see §3) |
| Bluetooth | Print receipts to a thermal receipt printer |
| Notifications | Remind you to open/close the day, chase dues, warn about low or expiring stock |
| Exact alarms | Fire those reminders at the time you set |
| Storage (Android 9 and older) | Save backup files to your Downloads folder |
All notifications are generated on your phone. Dokan does not use push notifications and has no server that could send you one.
Dokan also declares the standard Internet permission, which Android requires for app development tooling. The app makes no network requests during normal use.
7Children
Dokan is a business tool intended for shop owners and is not directed to children under 18. We do not knowingly collect information from anyone, including children.
8Changes to this policy
If we change this policy we will update the date at the top and publish the new version at this address. If a future version of Dokan ever adds a feature that sends data off your device, we will update this policy before that version is released and make the change clear in the app.
