Privacy Policy

Last updated: July 14, 2026

This Privacy Policy explains how Nijer Bus ("the app", "we", "us") collects, uses, and protects information when you use the app on Android. Nijer Bus is developed and maintained independently for Dhaka commuters, and we've tried to keep this policy as plain and direct as the app itself.

1. Information we collect

We collect only what's needed to make bus and metro search, live tracking, and trip alarms work:

Account information — if you register, your email address is stored on our server, encrypted with AES-256-GCM before it's ever written to the database.
Location data — used to find nearby stops, show your position on the map while you travel, and power the follow-me / live-tracking view. Location is processed to deliver these features and is not sold to third parties.
Search & trip activity — the routes you search for and the trips you set alarms for, so the app can show your recent searches and trigger alarms at the right time.
Device & usage data — basic technical information (device type, app version, crash logs) used to keep the app stable and fix bugs.
Game data (optional) — if you play the built-in Tic Tac Toe mini-game, your scores may be stored to power leaderboards or stats.

2. How we use your information

To run core features: route search, live location tracking, nearby-stop suggestions, fare estimates, and trip alarms.
To keep your account and preferences (like dark mode or language) in sync across sessions.
To detect and prevent duplicate accounts or abuse of the registration system.
To show you in-app notifications about service updates, events, or announcements.
To display advertising through Google AdMob, which helps keep the app free (see Section 4).

3. How your data is protected

Communication between the app and our server is encrypted end-to-end using AES-256-GCM, and sensitive fields such as your email are encrypted before storage. Our backend runs on a dedicated server with hardened configuration, and we do not store payment information within the app itself.

4. Third-party services

Nijer Bus uses the following third-party services, each governed by its own privacy policy:

Google AdMob — displays ads within the app and may collect device identifiers and usage data for ad personalization, in line with Google's own advertising policies.
Google Play Services — used for app distribution, in-app updates, and standard platform functionality.

You can opt out of personalized advertising through your device's Google settings (Settings → Privacy → Ads).

5. Location permission

Location access is optional but required for live tracking, nearby-stop search, and follow-me mode. You can grant, deny, or revoke this permission at any time from your device's app settings. If denied, the app will still work for manual route search — you just won't see live positioning or nearby-stop suggestions.

6. Data retention & deletion

We keep your account and trip data for as long as your account is active. You can request permanent deletion of your account and associated data at any time from within the app's settings, or by emailing us directly — we'll process the request without requiring further justification.

7. Children's privacy

Nijer Bus is not directed at children under 13, and we do not knowingly collect personal information from children. If you believe a child has provided us with personal data, please contact us and we will remove it.

8. Changes to this policy

We may update this Privacy Policy as the app evolves. Material changes will be reflected by updating the "Last updated" date above, and significant changes may also be announced in-app.
