Welcome to Lingy ("we," "our," or "us"), developed by NexByte Tech.
We are committed to protecting your privacy and providing a transparent and secure language-learning experience.
This Privacy Policy explains how information is handled when you use the Lingy mobile application (the "App").
Lingy is built with an offline-first, privacy-focused architecture. The App does not require account registration, and your core learning progress is stored locally on your device.
Lingy operates primarily on your device. The following information is generated during your learning journey and stored locally using Android's local storage:
User Profile Data: Your chosen display name, avatar emoji, and native/target language preferences.
Learning Progress & Statistics: XP earned, level status, completed lessons, mastered vocabulary words, daily streak count, study hours, and achievements.
App Preferences: Daily practice goal, audio volume settings, sound effect preferences, and appearance theme selections (Dark / AMOLED).
This information is stored locally on your device and is not transmitted to NexByte Tech.
NexByte Tech does not have access to, view, sell, or share your locally stored learning data.
Important: If you manually back up or transfer your Android device data, your locally stored App data may be included in that backup or transfer according to your device's backup settings.
Lingy requests only the permissions necessary to provide its educational features.
Purpose:
Used for interactive pronunciation drills and speaking exercises.
How it is handled:
When you use speaking exercises, audio is processed for the pronunciation/speech-recognition functionality. Lingy does not intentionally record or permanently store your voice recordings or upload them to NexByte Tech's servers.
Your control:
You can grant or revoke microphone access at any time through Android Settings:
Settings → Apps → Lingy → Permissions
Purpose:
Used to send optional daily practice reminders to help you maintain your study routine.
Your control:
You can enable or disable notifications from the App's Settings or Android System Settings.
Purpose:
These permissions may be used to:
Display web-based resources such as this Privacy Policy.
Check network connectivity status.
Support standard Google Play and Android platform services.
Lingy does not use network access to upload your locally stored learning profile or progress to NexByte Tech.
We do not sell, rent, trade, or monetize your personal information.
Your learning data and App preferences remain stored locally on your device while the App is installed, unless you reset or delete the data.
You can reset your course progress through:
Settings → Reset Progress
You can permanently delete locally stored Lingy data by:
Uninstalling Lingy, or
Clearing the App's data through Android Settings:
Settings → Apps → Lingy → Storage → Clear Data
Clearing the App's data or uninstalling the App removes the locally stored user profile, learning progress, preferences, and statistics from the device.
Lingy is designed for general audiences and language learners of different ages.
We do not knowingly collect, solicit, or store personally identifiable information from children under the age of 13, or under the applicable minimum age in jurisdictions where a higher age requirement applies.
Because Lingy does not require an account, email address, phone number, or online identity, users can use the App without creating an online profile with NexByte Tech.
If a parent or guardian believes that a child has provided personal information directly to us, please contact us using the contact information below.
We take reasonable measures to protect information handled by the App.
Lingy's privacy-focused design keeps core learning information on your device rather than maintaining a centralized database of user learning profiles.
Because NexByte Tech does not receive your locally stored learning profile or progress, this information is not maintained in our servers.
We may update this Privacy Policy from time to time to reflect:
App updates or new features.
Changes to our privacy practices.
Legal or regulatory requirements.
When we make changes, we will update the "Last Updated" date at the top of this Privacy Policy.
We encourage you to periodically review this page for the latest information.
If you have questions, concerns, or feedback regarding this Privacy Policy or your privacy while using Lingy, please contact us.
