Introduction

HAN•GL ("we," "our," or "us") is committed to protecting your privacy. This Privacy Policy explains our data practices for the HAN•GL mobile application.

Personal Information

The HAN•GL app does not collect or store any personally identifiable information. Specifically:

We do not require account creation or login
We do not collect your name, email, or any contact information
We do not track your location
We do not display advertisements

Analytics and Usage Data

To improve the app experience and fix technical issues, we collect anonymized usage data and crash reports through Firebase Analytics and Firebase Crashlytics (services provided by Google). This data is not linked to your personal identity.

What we collect:

Device identifiers (anonymized and not linked to you personally)
App usage patterns (which chapters and lessons you view, quiz scores, time spent in the app)
Crash logs and error reports to help us identify and fix bugs
General device information (device model, operating system version)

What we DO NOT collect:

Your name, email, phone number, or any contact information
Your location or GPS coordinates
Photos, contacts, or other personal files
Advertising identifiers (we explicitly disable the AD_ID permission)

How we use this data:

Understand which features users find most helpful
Identify and fix crashes and technical errors
Improve the overall app experience
Make decisions about future content and features

Important: This analytics data is NOT used for advertising, NOT sold to third parties, and NOT linked to your personal identity. It is aggregated and anonymized data used solely to improve the app.

Local Storage

All app content (lessons, audio, images) is bundled with the app and stored locally on your device. Your learning progress is saved only on your device and is not transmitted to any servers.

Third-Party Services

HAN•GL uses Google Firebase for analytics and crash reporting. Firebase is a trusted service provider that helps us understand how users interact with the app and identify technical issues.

Firebase Services We Use:

Firebase Analytics - Tracks anonymous usage patterns and app interactions
Firebase Crashlytics - Monitors app crashes and errors to help us fix bugs

Data Security: All data collected by Firebase is transmitted securely and stored on Google's servers. Firebase is subject to Google's privacy policies and security standards. You can learn more about how Firebase handles data at https://firebase.google.com/support/privacy.

No Other Third Parties: We do not share your data with any other third-party services, advertising networks, or data brokers.

Children's Privacy

HAN•GL is designed for general audiences, including children. We comply with the Children's Online Privacy Protection Act (COPPA) and similar children's privacy laws.

While we collect anonymized analytics and crash data (as described above), we do not collect any personal information that could be used to identify a child, such as name, email address, phone number, photos, or location. The analytics data we collect is not linked to any individual user and is used solely to improve the app.

We do not require parental consent because we do not collect personal information from children. However, parents should review this Privacy Policy to understand what data is collected through normal app use.

Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page and updating the "Last updated" date.

Website Analytics

Our website (hangl.app) uses Google Analytics 4 (GA4) to understand how visitors interact with our landing page. This helps us improve the website experience and measure the effectiveness of our content.

What we collect on the website:

Page views and navigation patterns
Button clicks (e.g., app store download buttons)
General device and browser information
Approximate geographic region (country-level)

Important: This website analytics data is anonymized and does not include any personally identifiable information. No cookies are used for advertising purposes. You can opt out of Google Analytics by installing the Google Analytics Opt-out Browser Add-on.

Waitlist

If you joined our waitlist prior to app launch, we collected your email address, platform preferences, and primary language solely to notify you when HAN•GL became available. This data is stored in a private Google Sheet and is not shared with third parties. You may request deletion of this data at any time by contacting us.
