Privacy Policy

Last updated: May 22, 2026

This Privacy Policy explains how the LaoLingo mobile application ("LaoLingo", "the app", "we", "us") collects, uses, and shares information when you use it. By using LaoLingo, you agree to the practices described here.

1. Information we collect

Information you provide

• Translation content. Text you enter, speech you record, and images you upload or capture for translation are processed to produce a translation or text-recognition result.

Information collected automatically

• Usage and analytics data. We collect in-app events (for example, opening a course, studying vocabulary, or subscribing) and basic device information to understand how the app is used and to improve it.
• Device identifiers. An app-instance identifier and similar identifiers are used by our analytics provider.
• Approximate location. A coarse, country-level location may be derived from your IP address by our analytics provider. We do not collect precise GPS location.
• Diagnostic data. If an error occurs, limited technical information such as device model and app version may be recorded to help us fix problems.

Purchases

• Subscription information. If you purchase a subscription, the transaction is handled by Google Play. We receive purchase records (such as order identifiers and purchase status) to activate and verify your subscription. We do not receive or store your full payment card details.

LaoLingo does not require you to create an account, and we do not ask for your name, address, or phone number.

2. How we use information

• To provide translation, text recognition, and language-learning features.
• To operate, maintain, and improve the app and its content.
• To understand usage trends and measure feature performance.
• To process and verify subscriptions.
• To diagnose and fix technical problems.

3. Third-party services

To deliver its features, LaoLingo relies on the following third-party services. Your information may be processed by them in accordance with their own privacy policies:

• Translation and text-recognition providers. Text, speech, and images you submit for translation are sent to third-party translation and OCR services (which may include Google, Microsoft, and other providers) to generate results.
• Google Firebase / Google Analytics. Used for app analytics and diagnostics.
• Cloud backend services. Used to store app configuration, subscription order records, and diagnostic logs.
• Google Play Billing. Used to process subscription purchases.

We do not sell your personal information.

4. Data retention and storage

• Your translation history is stored locally on your device. You can delete individual records in the app, and clearing the app's data or uninstalling the app removes it.
• Analytics, diagnostic, and subscription records are retained only as long as needed for the purposes described above.
• Information is transmitted over encrypted (HTTPS) connections.

5. Your choices

• You can clear your translation history at any time from within the app.
• You can limit ad and analytics identifiers through your device's system settings.
• You can uninstall the app to stop all further data collection.
• You can manage or cancel a subscription in your Google Play account.

6. Children's privacy

LaoLingo is not directed to children under 13, and we do not knowingly collect personal information from children. If you believe a child has provided us with information, please contact us so we can remove it.

7. International users

LaoLingo is available globally. By using the app, you understand that your information may be processed in countries other than your own, where data protection laws may differ.

8. Changes to this policy

We may update this Privacy Policy from time to time. When we do, we will revise the "Last updated" date above. Continued use of the app after changes take effect constitutes acceptance of the updated policy.
