Bandlio Privacy Policy

Effective date: 2026-11-13

Bandlio ("the app") is an academic vocabulary study app for IELTS preparation provided by DDJ B1 ("we", "us"). You learn words with flashcards, review them, take quizzes and follow a daily plan based on the exam date you enter. It has no account system, no login and no server operated by us.

Information stored on your device

Your study progress (which words you learned and when they are due for review, starred words, days you finished your daily goal) and your settings (exam date, meaning language, daily maximum, pronunciation accent, theme, notification preferences) are stored locally on your device. The app itself does not send this information to us, and we have no server to receive it. The word list, meanings and example sentences are bundled inside the app and work offline.

Uninstalling the app deletes the information stored in the app. Android's standard app backup may include app data in your own Google account backup if you have device backup enabled; that backup is controlled by you and Google, not by us.

Pronunciation

When you tap the speaker button, the app asks your phone's text-to-speech engine to read the word aloud. The app does not record audio and does not use the microphone.

Sharing

If you tap Share my progress, the app creates a short text (your streak and number of words learned) and passes it to the app you select through Android's share sheet. The app does not send it anywhere by itself.

Permissions

Bandlio does not request location, camera, microphone, contacts, SMS, phone or file-storage access.

Advertising and information collected automatically

The app displays advertisements provided by Google AdMob inside the app only (never in notifications or in the widget). To serve and measure ads and to prevent fraud, the AdMob SDK may collect and share with Google information such as your device's advertising identifier and other device identifiers, approximate location derived from your IP address, app interactions (for example ad views and taps), crash logs and diagnostics. This data is shared with Google as a third party for advertising, analytics and fraud prevention purposes. For more information see https://policies.google.com/technologies/partner-sites.

For users in the European Economic Area (EEA), the United Kingdom and other regions where required, the app presents a consent form via Google's User Messaging Platform (UMP) before personalized advertising data is used; if you decline, non-personalized ads are shown. You can change your choice from the app's Settings screen ("Ad privacy settings") and reset or limit ad personalization in your device settings.

Word list and trademarks

The word list is based on the New Academic Word List 1.2 by Browne, Culligan and Phillips, licensed under CC BY-SA 4.0. IELTS is a registered trademark of the British Council, IDP and Cambridge. Bandlio is an independent study app and is not affiliated with or endorsed by them.

Children

The app is not directed to children under 13, and we do not knowingly collect personal information from children.

Your rights

Your study progress and settings exist only on your device; uninstalling the app removes them. Depending on your region (e.g. GDPR, CCPA), you may have rights regarding data processed by the advertising SDK; you can exercise ad-related choices through the consent form and your device's ad settings.

Changes to this policy

We may update this policy from time to time. Changes will be posted on this page with an updated effective date.
