LittleDuo Privacy Policy

Last updated: 10th February 2026

        Summary for parents: LittleDuo is designed for children. We do not collect personal data, do not use analytics or advertising SDKs, and do not track your child's activity. The only data stored is app preferences (language, audio settings) saved locally on your device.
    

1. Introduction

LittleDuo (“the App”) is a children’s educational application designed to help young learners build early vocabulary and understanding of everyday topics such as the alphabet, numbers, colours, animals, and common objects. The App focuses on learning English with support from the child’s local language to make learning easier and more intuitive. Currently, LittleDuo supports Czech as the local language, and additional languages may be added in the future to support children from different regions. The App is designed for children and does not require account creation or the submission of personal information.

2. Information We Collect

We do not collect any personal information.

The App stores the following data locally on your device only:

App language preference (English or Czech)
Audio mode settings (single/dual language, tap-to-play/auto-play)
Background music preference (on/off)
Subscription/premium status

This data is stored using the device's local storage (SharedPreferences) and is never transmitted to any server.

3. In-App Purchases

The App offers optional premium subscriptions through Google Play. All purchase transactions are handled entirely by Google Play and are subject to Google's Privacy Policy. We do not process, store, or have access to any payment information.

4. Third-Party Services

The App uses the following third-party services:

Google Play Billing — for processing in-app purchases. See Google's Privacy Policy.

We do not use any analytics, advertising, crash reporting, or social media SDKs.

5. Children's Privacy (COPPA Compliance)

LittleDuo is designed for use by children under the supervision of a parent or guardian. We are committed to protecting children's privacy:

We do not collect personal information from children.
We do not include behavioral advertising.
We do not include social media integration.
We do not allow children to make purchases without parental involvement (purchases are gated through the device's app store).

6. Data Security

Since all data is stored locally on your device and no data is transmitted over the internet (except for Google Play purchase verification), there is minimal risk of data exposure. You can clear all App data at any time through your device's Settings > Apps > LittleDuo > Clear Data.

7. Changes to This Policy

We may update this Privacy Policy from time to time. Any changes will be reflected in the "Last updated" date at the top of this page. We encourage you to review this policy periodically.
