SmartEdu - English to Bangla · Package: com.osmanit.smartedu · Developer: Osman IT
Last updated: November 9, 2026

This Privacy Policy explains what information the SmartEdu - English to Bangla mobile application ("the app", "we", "us") processes, why, and which third-party services are involved.

1. Information we process

a. Text you translate

• Translations are performed on your device using Google ML Kit. The text you type is not sent to our servers or to any online translation service.
• The first time you translate between two languages, the app downloads the required language model (about 30 MB) from Google's servers. After that, translation works offline.

b. Dictionary lookups

• When you search a word in the Dictionary, that word only is sent over an encrypted HTTPS connection to the Free Dictionary API (api.dictionaryapi.dev) to fetch definitions, phonetics, examples and synonyms.
• While you type in the Dictionary search box, the typed letters are sent over HTTPS to the Datamuse API (api.datamuse.com) to show word suggestions. No account or device identifier is sent with these requests.

c. Learning Insights

• After a translation that involves English, the app looks up up to 3 English keywords of the sentence in the same Free Dictionary API to show meanings, pronunciation and a short quiz. Only those individual words are sent.

d. Grammar Checker

• When you tap "Check Grammar", the sentence you entered is sent over HTTPS to the LanguageTool API (api.languagetool.org) to find grammar, spelling and punctuation mistakes. No account or device identifier is sent with the request.
• When the device is offline, a basic check runs on your device instead and nothing is sent.

e. Voice input

• When you tap a microphone button, the app opens your device's speech recognition service (on most devices provided by Google). That service converts speech to text and may process audio on its own servers under its own privacy policy.
• SmartEdu - English to Bangla itself does not record, store or upload audio, and does not request the microphone permission. We only receive the recognized text.

f. Text-to-speech

• The speaker button uses your device's built-in Text-to-Speech engine.

g. History and favorites

• Your translation history and favorites are stored only on your device (local database). We never upload them.
• You can delete them at any time inside the app, or by clearing the app's data or uninstalling the app.

h. Advertising (Google AdMob)

• The app shows full-screen (interstitial) ads through Google AdMob.
• Google AdMob may collect and process the Android Advertising ID, IP address, general device information (model, OS version), approximate location derived from the IP address, and ad interaction data in order to serve and measure ads and to prevent fraud.
• Users in the European Economic Area, the United Kingdom, Switzerland and other regions where it is required are asked for consent through Google's User Messaging Platform before ads are personalized. You can change this choice at any time from the app menu: Ad privacy settings.
• You can reset your Advertising ID or opt out of personalized ads in your device settings (Settings > Google > Ads, or Settings > Privacy > Ads).

2. Third-party services

Google ML Kit and Google AdMob may send limited diagnostic and usage information (for example performance metrics and crash data) to Google to operate and improve their services.

3. Data sharing and selling

• We do not sell, rent or trade personal data.
• We do not operate our own servers and do not collect your name, email address, contacts, photos, files or precise location.
• Data is shared only with the third-party services listed above, for the purposes described.

4. Data security

All network communication (dictionary lookups, grammar checks, model downloads, ads) uses encrypted HTTPS/TLS connections.

5. Data retention and deletion

Data stored by the app stays on your device until you delete it in the app, clear the app's data, or uninstall the app. Data processed by Google services is retained according to Google's policies. For any request, contact us at the email below.

6. Children

SmartEdu - English to Bangla is intended for users aged 13 and older. It is not directed at children under 13, and we do not knowingly collect personal information from children. If you believe a child has provided personal information through the app, please contact us.

7. Permissions used by the app

• INTERNET – download language models, fetch dictionary data, check grammar and load ads.
• ACCESS_NETWORK_STATE – check whether the device is online.
• AD_ID – used by Google AdMob for advertising (added automatically by the AdMob SDK).

The app does not request microphone, camera, location, contacts or storage permissions.

8. Changes to this policy

We may update this Privacy Policy from time to time. Changes take effect when the updated policy is posted on this page, and the "Last updated" date will be revised.
