Periodic Table Explorer Terms & Conditions

1. Acceptance of Terms

By downloading, accessing, or using Periodic Table Explorer, you confirm that you have read, understood, and agreed to be bound by these Terms and Conditions and our Privacy Policy. If you do not agree, please discontinue using and uninstall the application.

2. Educational Purpose & Scientific Reference

Periodic Table Explorer is an interactive reference and study aid provided for educational, scientific, and informational purposes for students, teachers, and researchers. While element data, atomic weights, electron configurations, Bohr models, and properties have been meticulously compiled from IUPAC (International Union of Pure and Applied Chemistry) and standard scientific references, the software is provided on an 'as-is' and 'as-available' basis without warranty of any kind.

3. Account-Free Architecture & Local Storage

Periodic Table Explorer does not require or support user account registration. All element bookmarks, quiz statistics (scores, streaks, accuracy), and customization settings are stored locally on your device via SharedPreferences. Clearing your device application storage or uninstalling the app will permanently reset all locally saved bookmarks and quiz progress.

4. Third-Party Advertising & Rewarded Ad Features

To provide free access to all 118 elements and study features, Periodic Table Explorer displays third-party advertisements served via the Google Mobile Ads (AdMob) SDK (including App Open, Banner, Interstitial, and optional Rewarded Video ads). Rewarded ads provide optional in-game lifelines (such as 50:50 quiz hints). Ad content is subject to Google AdMob's terms and advertising policies.
