Elemora Privacy Policy

Effective date: 2026-10-22

Elemora — an offline periodic table app that lets you look up all 118 chemical elements and practice them with quizzes ("the app") — is provided by DDJ A1 ("we", "us"). This policy explains what data the app handles and how. Elemora has no account system and we do not operate a server for it.

Data stored on your device

Your favorite elements, quiz scores, mistake notes, mastery progress, daily goal and streak, reminder times and app settings are stored only on your device and are not transmitted to us. The element data itself is built into the app, so looking up elements does not require an internet connection. Uninstalling the app deletes this data from your device. Android's standard app backup may include this data in your own Google account backup if you have device backup enabled; that backup is controlled by you and Google, not by us.

Sharing

When you use Share (for example an element card or a quiz score card), the app hands the content to the app you choose in the Android share sheet. The app does not upload anything by itself.

Permissions the app asks for and why

• Notifications (optional). For the reminders you choose (for example a morning "element of the day" or an evening quiz reminder). You can decline; the table, element details and quizzes still work.
• Alarms & reminders and run at startup. So that reminders and the home screen widget work on time and are restored after your phone restarts or the time or time zone changes.
• Internet access and the advertising identifier (AD_ID). Used only by the advertising components described below. The periodic table and quizzes work offline.

The app does not use the camera, the microphone, your location permission or your contacts.

Information collected automatically

When you use the app, certain information may be collected automatically by third-party SDKs used for advertising. This may include:

• Your device's Internet Protocol (IP) address, which may be used to estimate your approximate (general) location
• Device or other identifiers, such as your device's advertising identifier (Advertising ID) and app set ID
• App interactions, such as session time, screens viewed, and ad views and taps
• Crash logs and diagnostic information, such as the mobile operating system and device model you use and ad performance data

This information is collected by the advertising SDK and shared with Google (AdMob) and its advertising partners for advertising, analytics, and fraud prevention, security and compliance purposes. It is encrypted in transit. The app itself does not send your quiz results, favorites or settings off your device, and we do not link the advertising data to them.

Advertising

The app displays advertisements provided by Google AdMob: a banner at the bottom of the main screens, an ad when the app starts, and full-screen ads only at natural pauses (for example when a quiz round's results open). No full-screen ads are shown while you are answering quiz questions. To serve ads, AdMob and its partners may access your device's Advertising ID and the information described above. For users in the European Economic Area (EEA), the United Kingdom, and other regions where required, the app presents a consent form via Google's User Messaging Platform (UMP) before personalized advertising data is used; if you decline, non-personalized ads are shown instead. You can reset or limit ad personalization at any time in your device settings (Settings → Google → Ads), and you can change your consent choice from the app's Settings screen.

For more information on how Google uses data when you use partners' apps, see https://policies.google.com/technologies/partner-sites.

Children

Elemora is a general-audience study tool and is not directed to children under 13. We do not knowingly collect personal information from children.

Your rights

Because your data exists only on your device, you are in direct control of it: you can clear your quiz history and favorites at any time, and uninstalling the app removes everything the app stored. Depending on your region (e.g. GDPR in the EEA/UK, CCPA in California), you may also have rights regarding data processed by advertising SDKs; you can exercise ad-related choices through the consent form and your device's ad settings described above.

Changes

We may update this policy. Material changes will be reflected on this page with a new effective date.
