Effective April 24, 2025

We respect your privacy and are committed to protecting your personal information. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our language learning application.

Information We Collect

To provide you with our language learning services, we collect and process the following types of information:

• Account Information: When you register for an account, we collect your name, email address, language preferences, and account credentials. If you sign up using a third-party service such as Google, we may collect the information that you agreed to share with us from that service.
• Learning Data: We track your learning progress, performance metrics, completed exercises, and content preferences to personalize your learning experience.
• User Content: We store any content you create, upload, or record within the app.
• AI-Generated Content: We use Large Language Models (LLMs) to generate language learning stories and exercises. The prompts you provide and your interactions with this content may be processed by these AI services.

• Usage Information: We gather data about how you use the app, including features accessed, time spent, and interaction patterns.

Cookies

Our application uses cookies and similar tracking technologies to enhance your experience and collect information about how you use our service:

• Essential Cookies: These are necessary for the app to function and cannot be turned off. They enable core functionality such as security, network management, and account access.
• Analytical Cookies: These help us understand how users interact with our app by collecting and reporting information anonymously.
• Third-Party Cookies: Our app includes YouTube embedded content, which may set their own cookies when you interact with these features. Please refer to YouTube's privacy policy for information about these cookies.

You can manage cookie preferences through your browser settings, though this may impact certain functionalities of our service.

Server Logs

Our application automatically records information in server logs, including:

• IP addresses
• Browser type and settings
• Date and time of requests
• App feature usage and interactions
• Error reports and performance data

These logs help us monitor system performance, troubleshoot technical issues, and protect the security of our infrastructure. Our server infrastructure is hosted on servers in the EU and US to ensure the best latency and performance for our users. We do not share server logs with third parties unless required by law or to protect our rights and property.

How we process your data

We use the information collected to operate our services. For example, we process you language learning progress (e.g. words looked up) to give you better insights into your progress.

Data Retention

We retain your personal information for as long as necessary to provide you with our services and for legitimate and essential business purposes, such as:

• Maintaining your learning progress and history

When we no longer need your personal information, we will securely delete or anonymize it. Learning content you've created may be retained in anonymized form to improve our educational algorithms and content quality.

Your information may be processed on servers located outside of your country of residence. We implement appropriate safeguards to protect your information when it is transferred internationally, including standard contractual clauses and data processing agreements with our service providers.

Children's Privacy

Our service is not directed to children under the age of 13 (or the applicable age in your jurisdiction). If we learn that we have collected personal information from a child without parental consent, we will take steps to delete that information promptly.
