Effective Date: July 8, 2026
The "Periodic Elements (Interactive Chemistry)" mobile application (referred to below as "the App" or "this App") is designed as an educational index, visualization tool, and offline quiz platform. This Privacy Policy documents our strict policies regarding the collection, use, and disclosure of personal data and non-personal data when you use our mobile application.
The primary architecture of the App is built to run entirely offline without requiring an active internet connection.
We do NOT require user registration, account creation, or login credentials.
We do NOT collect, transmit, share, store, or use any user personal data, personal identifiers, or device-specific information.
There is no server-side backend associated with this App.
For absolute clarity, we do not access, process, or collect any of the following:
Personal Information: Names, email addresses, mailing addresses, phone numbers, or passwords.
Financial Information: Payment card numbers, billing information, or transaction histories.
Device and Network Information: IP addresses, MAC addresses, IMEI numbers, device logs, hardware models, or operating system versions.
Location Information: Precise or coarse GPS or network-based location data.
Device Permissions: Contacts, microphone, camera, calendar, photo gallery, or file system storage.
Any configurations, options, and states you customize within the App are stored locally and exclusively on your physical device:
Settings & Preferences: Your selected primary presentation modes (e.g., standard atomic weight vs. physical state temperatures), specialized dark elements themes, and haptic guides toggles.
Quiz Stats: Your local high scores, quiz accuracy ratios, and earned element reward milestones.
Storage Mechanism: This configuration data is saved strictly using local sandboxed system storage APIs (Android SharedPreferences / iOS UserDefaults). This data is completely isolated, remains entirely on your physical device, and is never transmitted to any external servers or third parties. It is deleted automatically if you uninstall the App.
To guarantee a completely private and unmonitored educational experience:
Zero Analytics: The App does not contain telemetry, diagnostic, or tracking SDKs (such as Firebase Analytics, Flurry, or Google Analytics).
Zero Ads: The App is completely ad-free. It does not integrate with any mobile advertising networks or tracking identifiers (such as Android Advertising ID or iOS IDFA).
Zero External Calls: The App does not link, integrate, or make API calls to third-party web domains, APIs, or data clouds.
This App is educational and designed to be safe for all demographics, including children.
Because we collect absolutely zero personal information or persistent device identifiers, the App is fully compliant with the Children’s Online Privacy Protection Act (COPPA), General Data Protection Regulation (GDPR) children's guidelines, and the Google Play Families Policy.
We do not knowingly or unknowingly collect or track any data from children of any age.
The App operates under standard sandboxed execution environments and does not request broad permissions (such as Read External Storage, Access Accounts, or precise location). Because there are no outbound network packets generated by the App, your local data is fundamentally secure from interception or leakage.
We may periodically update this Privacy Policy to maintain alignment with updated operating system specifications or regulatory updates. Any changes will be published directly within updated versions of the App, on our official store listing page, or at our linked policy webpage. We encourage users to check this policy page periodically.
