Bahon Boi

Privacy Policy

Bahon Boi app · Effective date: TODO publication date

Draft: this document is under review and not final. It will be finalized before the app is published.

This policy explains what information the Bahon Boi app (“the app”) works with, where it is kept and how you control it. The app is made and published by Md. Risul Islam Munna (“the developer”). It applies to the Bahon Boi app only.

1. Summary

  • The records you enter are stored on your phone, in the app’s own storage. They are not sent to the developer, and the developer cannot see them.
  • No account or sign-in is needed to use the app.
  • The current version includes no advertising, analytics or crash-reporting service.
  • You choose where backup files are saved.

2. Information you keep in the app

The app works with information that you enter or add yourself, such as:

  • Vehicles: number plate, type, manufacturer and model, purchase date, photos and notes.
  • Owners: name, phone number, address, contribution and share.
  • Drivers: name, phone number, NID and driving licence numbers and photos, emergency contact, and assignment history.
  • Accounts: income, money received, expenses, payments, adjustments, reductions and notes.
  • Documents: type, number, issue and expiry dates, and photos.
  • App settings such as language and theme.

If you store information about drivers, owners or other people, it is your responsibility to have their permission and to follow the law that applies to you.

3. Where information is stored

Records are stored in a database in the app’s private storage on your phone, and photos in the app’s own folder. There is no Bahon Boi server. Use a screen lock to protect your phone.

4. Camera and photos

When you choose to add a photo of a vehicle, driver, document or bill, the app opens the camera or the photo picker. A resized copy of the photo you pick is kept in the app’s storage.

5. Backups

  • App backups (Android): after you set up Backup & Restore and choose a folder, the app saves a data backup about once a day, photo backups on the schedule you choose, and a backup whenever you tap “Back up now”. Backups contain your records and photos.
  • Normal backups are not encrypted — anyone who has the files can read or restore them.
  • Protected backups (optional) are encrypted with a recovery key. If the recovery key is lost together with the app installation, protected backups cannot be opened; the developer cannot recover the key.
  • If you choose a folder that syncs with a cloud service, the files will go to that service and its terms apply.
  • Android system backup: if Android’s own backup is turned on in your phone settings, Android may back up app data to your Google account. The files that store the backup key are excluded from it. This is controlled by Android and Google, not by the developer.

6. Google Sheets / Drive connection

The app contains a Google Sheets and Drive sync component, but it is inactive in the current version and the app does not sign in to your Google account. If it is ever turned on, this policy will be updated first.

7. Update check, advertising and analytics

Update check (Android): to tell you when a new version is available, the app downloads one small public file, https://apps.munna.dev/app-config/config.json. This happens in the background at most once a day when the phone is online, and whenever you tap “Check for updates” (or “Rate app” before a store listing is known). The request contains no records, names, account or device identifiers — only what every web request carries, such as your IP address and a generic app user agent, which the website host (GitHub Pages) may log. Nothing is uploaded. If the phone is offline or the file cannot be read, the app works exactly as before.

“Rate app” and “Update” open the app’s own Google Play page; anything you do there is covered by Google’s terms.

The current version includes no advertising network, analytics or crash-reporting service, and does not send usage information to the developer.

8. Device permissions

  • Camera / photos — only when you choose to take or pick a photo.
  • Backup folder access — only to the folder you choose for backups.
  • Background work — used to run the scheduled backup. The app does not send document-reminder notifications.
  • Internet — used only to download the public update file described in section 7 (it is also declared by the inactive Google sign-in component). Your records are not uploaded by the current version.

TODO Confirm the final permission list from the release build’s merged Android manifest and update this section.

9. Deleting information

  • Entries you delete in the app are removed from lists and totals.
  • To remove all of the app’s data from your phone, clear the app’s data in phone settings or uninstall the app.
  • Backup files stay in the folder you chose until you delete them yourself.
  • The developer holds none of your records, so there is nothing to request deletion of. If you email for help, only what you send is received.

10. Children

The app is made for vehicle owners and transport businesses, not for children.

TODO Align with the Play Console “Target audience and content” answers.

11. Changes to this policy

This policy may be updated when the app changes. The updated policy will be published on this page with a new effective date.
