Privacy Policy
Last updated: May 9, 2026
English Bujhbo ("we," "us," or "the app") provides a daily English-learning service for Bangladeshi learners. This Privacy Policy explains what information we collect when you use our mobile app or website, how we use it, and the choices you have. By using English Bujhbo you agree to the practices described here.
1. Information we collect
1.1 Account information
When you sign up, we collect the email address and display name associated with your Google account (or the email address you provide). We use Firebase Authentication to manage sign-in. We do not see or store your Google password.
1.2 Learning data
We collect information about your activity inside the app, including:
- Lessons started, completed, and your scores
- Attempts on individual quiz questions, flashcards, and speaking prompts
- Daily streak, total points, and chapter progress
- Game scores, levels reached, and weak-item tracking
- Your selected goal, level, and language preference
1.3 Voice recordings (speaking practice)
When you tap the microphone button to practice speaking, we record up to 8 seconds of audio. That audio is sent to a third-party speech-recognition service (DeepInfra, running OpenAI's Whisper model) so we can transcribe what you said and score your pronunciation. We do not retain your voice recordings on our servers; the audio is discarded after transcription. The transcript and your accuracy score are saved with your learning data so you can review your progress.
1.4 Notifications
If you enable daily reminders, we use your device's local notification system. We do not collect or store push tokens for our own use at this time.
1.5 Payment information (web only)
If you choose to upgrade to the full course via our website, payment is processed by EPS (or another local payment provider). We never see or store your card number, mobile-banking PIN, or bank login. We store the transaction ID, package purchased, amount, and timestamp so we can grant you access and provide receipts.
1.6 Device and analytics information
Firebase Analytics and Firebase Crashlytics collect standard device information so we can understand how the app is used and diagnose crashes. This includes:
- Device model, operating system version, and language
- App version and build number
- Anonymous usage events (e.g. lesson started, lesson completed)
- Crash logs with stack traces
We do not collect your precise location, contacts, photos, or files. The microphone is accessed only while you are actively recording for a speaking exercise.
2. How we use information
We use your information to:
- Provide the lessons, scoring, and progress tracking you sign up for
- Save your progress so you can resume on the same or another device
- Send the daily reminder you opted in to
- Score your pronunciation and show you per-word feedback
- Process payments if you upgrade
- Diagnose crashes and improve app stability
- Understand which features are used so we can improve them
- Detect and prevent abuse, fraud, and security incidents
3. Sharing with third parties
We share information with the following service providers, each only for the purpose listed:
- Google (Firebase Authentication, Analytics, Crashlytics, Remote Config, Cloud Messaging): sign-in, anonymous usage analytics, crash reporting, and remote feature flags.
- DeepInfra / OpenAI Whisper: short-term speech-to-text transcription of your speaking-exercise audio.
- EPS (and other Bangladesh-licensed payment gateways): processing one-time course payments made through our website.
- Hosting and infrastructure providers: hosting our database and servers in line with industry-standard security practices.
We do not sell your personal information. We do not share your information with advertisers. We do not allow third parties to use your data for their own marketing purposes.
We may disclose information if required by law, court order, or other legal process, or if necessary to protect the rights, property, or safety of our users or the public.
4. Data retention
We retain your account and learning data for as long as your account is active. If you delete your account (see Section 6), we promptly remove your learning history, attempts, achievements, streak, and notification preferences. Payment records are retained for accounting and tax purposes for up to seven years, but are anonymised so they no longer identify you personally.
Voice recordings are not retained. Crash logs and anonymised analytics events are retained for up to fourteen months, in line with Firebase's default retention settings.
5. Security
We use industry-standard measures to protect your information, including HTTPS encryption for all network traffic, hashed credentials via Firebase Authentication, and access controls on our databases. No system is perfectly secure, however, and we cannot guarantee absolute security. If we become aware of a breach affecting your personal information we will notify you and the appropriate authorities as required by applicable law.
6. Your rights
6.1 Access and correction
You can review your profile information, learning progress, and preferences at any time inside the app under the Profile tab. You can edit your display name, goal, and level there.
6.2 Deleting your account
You can permanently delete your account at any time:
- From the mobile app: Profile tab → Settings → Delete account.
- By email: send a request from your account email to support@bujhbo.com and we will complete the deletion within 30 days.
Account deletion removes your profile, learning history, attempts, achievements, streak, notification preferences, and game data. As described above, payment records are anonymised but kept for accounting compliance.
6.3 Notifications and microphone
You can disable daily reminders inside the app under Settings → Daily reminder, or in your device's system settings. You can revoke microphone access at any time in your device's system settings; the speaking exercises will become unavailable until you re-grant access.
7. Children's privacy
English Bujhbo is intended for users aged 13 and older. We do not knowingly collect personal information from children under 13. If you believe a child under 13 has provided us with personal information, please contact us at support@bujhbo.com and we will delete it.
8. International data transfers
Some of our service providers (such as Google Firebase and DeepInfra) process data outside Bangladesh. By using English Bujhbo you consent to this transfer. We require all our processors to protect your information to a standard at least as strong as this policy.
9. Changes to this policy
We may update this Privacy Policy from time to time. When we do, we will update the "Last updated" date at the top of this page. If the changes are material we will notify you in the app or by email. Your continued use of English Bujhbo after a change indicates your acceptance of the revised policy.
