Privacy Policy

Last updated: August 18, 2025

Friendly Summary

We keep your data safe and use it only to make your learning experience better. Here’s the quick version:

  • Sign-in is handled securely through Firebase by Google.
  • We store your progress and settings in private storage on Amazon Web Services (AWS).
  • We never sell your data.
  • There’s an optional setting to learn profanity in the target language — it’s off by default.
  • Kids under 13 can use the app with parental guidance.

Information We Collect

  1. Authentication Information
    – We use Firebase Authentication (a Google service) to let you sign up and sign in securely.
    – Depending on your sign-in method, Firebase may collect information such as your email address or identity provider details (e.g., Google, Apple).
  2. Application Usage Data & Settings
    – We store per-user app usage data (e.g., lesson progress, learning streaks, feature toggles) and your chosen settings.
    – This data is stored in secure private storage hosted on Amazon Web Services (AWS), not shared publicly.
  3. Optional Content Settings
    – The App includes an optional feature to enable lessons on common profane expressions in the target language.
    – This feature is disabled by default. If enabled, it may display language that is not suitable for children under 13.

How We Use Information

  • To provide you with personalized learning experiences.
  • To save your progress and settings across devices.
  • To improve the App and develop new features.
  • To ensure secure communication between the App and our private API.

We do not sell or rent your personal information to third parties.

Data Security

  • All communication between the App, Firebase, and our private API is encrypted.
  • Your data is stored securely using Firebase (Google) and AWS (Amazon) services.
  • While we take reasonable measures to protect your information, no system is 100% secure.

Children’s Privacy

  • The App is designed to be suitable for curious learners, including children under 13.
  • However, the profane expression feature is intended for older users and is off by default.
  • Parents or guardians should supervise use of the App if children under 13 are involved.
  • We do not knowingly collect personal information from children under 13 without parental consent, in compliance with COPPA (Children’s Online Privacy Protection Act).

  • You can review or update your settings in the App at any time.
  • You may request deletion of your account and associated data by contacting us at info@lang.guru.
