§ 01 1. Summary
The Atomurus app does not collect, transmit, sell or share any personal data. It has no sign-up or login, shows no ads, uses no analytics or tracking tools and never asks for your information. All content (periodic table, virtual lab, isomerism, calculators, 3D models and articles) ships inside the app and works offline.
§ 02 2. Who we are
Atomurus is an educational chemistry project behind the atomurus.com website and the Atomurus app for Android (package atomurus.com). This policy covers the app. The website has its own Privacy Policy, because it uses features the app does not (optional accounts, analytics and ads, always with consent).
§ 03 3. Data we collect
None. The app does not send us or any third party your name, email, phone number, location, contacts, photos, files, advertising ID, device identifiers, usage history or diagnostics. The app has no forms that send information.
§ 04 4. Data kept on your device
So the app can remember what you were doing, some information is stored only in the app's private storage on your device:
- preferences: light or dark theme, language and display options;
- your virtual lab bench (glassware, materials and notebook entries);
- study progress, calculation history and recent items.
This information never leaves the device and we have no access to it. It is deleted when you clear the app's data or uninstall the app. If Android automatic backup is enabled for your Google account, Android itself may include this data in your encrypted account backup; you control that in your device settings, under Google's policy.
§ 05 5. Permissions
The app requests only internet access, used when you tap a link to an external website (it opens in your browser). The app does not request camera, microphone, location, contacts, file storage or notifications.
§ 06 6. Third-party services
- Google Play: downloads, updates and aggregate install statistics are handled by Google Play under the Google Privacy Policy.
- Android System WebView: the Android component that renders the app's pages. It runs on your device; the app sends no data through it.
- External links: a link to another website opens in your browser, under that website's policy.
The app contains no advertising, analytics, social media or tracking SDKs.
§ 07 7. Children
Atomurus is an educational app and can be used by students of any age. Because the app collects no data from anyone, it collects no data from children or teenagers either.
§ 08 8. Your rights and data deletion
We hold no personal data from the app, so there is nothing of yours for us to access, correct, export or delete under Brazil's LGPD (Law 13,709/2018), the GDPR or similar laws. To erase everything the app stored on your device, open Settings → Apps → Atomurus → Storage → Clear data, or uninstall the app.
§ 09 9. Changes to this policy
If a future version of the app adds accounts, sync or any feature involving personal data, this policy will be updated before that version is published, with the new date at the top, and the app will ask for your consent where the law requires it.
