Welcome to Periodic Table Helper (“the App”).
Your privacy is important to us. This Privacy Policy explains how we handle information when you use the App.
1. 📱 About the App
Periodic Table Helper is an educational, offline chemistry reference tool designed to help users explore the periodic table, element data, and chemistry utilities.
The App is completely offline and does not require any login, account, or network connection to function.
2. 🧾 Information We Do Not Collect
We value your privacy — that’s why we designed this app to operate without collecting or sharing any personal or sensitive user data.
The App does not:
  • Collect, store, or share personal information
  • Collect or transmit device identifiers, IP addresses, or location data
  • Access or share contacts, photos, or files
  • Use cookies or analytics trackers
  • Include advertising SDKs, Firebase Analytics, or third-party tracking libraries
3. 💾 Data Stored on Your Device
Some features (like favorites, notes, and settings) are saved locally on your device only.
This means:
  • Data never leaves your phone or tablet.
  • You can delete all stored data anytime by uninstalling the app.
  • We have no access to any of your stored information.
Examples of local data:
  • Favorite elements
  • User notes and preferences
  • Theme and unit settings
All of these remain 100% private and offline.
4. 🌐 Internet & Permissions
The App does not require internet access or any sensitive permissions.
Permissions Used:
✅ None (No camera, microphone, location, storage, or network access)
This ensures your privacy is fully protected and simplifies your data safety declaration for Google Play.
5. 🧒 Children’s Privacy
This app is suitable for all ages, including educational use by children.
Since we do not collect or transmit any personal data, the App fully complies with:
  • The Children’s Online Privacy Protection Act (COPPA) (for U.S. users)
  • The EU GDPR for children’s data
  • Google Play Families Policy Requirements
No data collection or tracking of any kind occurs.
6. 🔐 Data Security
Because the App does not collect or share data, there are no transmitted data streams that could be intercepted.
All user data (favorites, notes, etc.) remain locally encrypted by Android’s internal storage mechanisms.
If you uninstall the App, all your local data will be permanently deleted.
7. ⚙️ Third-Party Services
Periodic Table Helper uses no third-party SDKs, no analytics services, no ads, and no external APIs.
All data displayed within the App (element properties, constants, etc.) comes from public scientific data sources bundled within the app itself (for example, NIST and Wikipedia datasets).
