The short version
GeoNum does not require an account, include advertising or analytics, or sell or share personal information. Practice data stays in local app storage on your device.
Operator and contact
GeoNum is operated by Yeonsun Shin, a sole proprietor doing business as Hedeonix (에데오닉스), Republic of Korea. The brand is presented as Hédéonix.

Data stored on the device
GeoNum stores practice attempts, category progress, app settings, reminder preferences, paused-session data, and content reports in local app storage. This information is used only to run the app, resume practice, show progress, and vary practice questions.
- Reset Learning Data removes practice history, progress, and paused sessions.
- Delete Practice & Report Data also removes saved content reports.
- App preferences and operating-system notification permissions remain unless changed separately.
- Uninstalling GeoNum removes app-local data according to the device operating system’s normal behavior.
Content reports and sharing
When you tap the report button, GeoNum saves the referenced exercise and selected reason locally. Nothing is uploaded automatically. If you choose Share Report, the system share sheet opens and you select the destination. Information shared that way is governed by that destination’s privacy practices.
Speech and notifications
Spoken practice uses the device operating system’s text-to-speech service. GeoNum does not operate a speech server. Voice availability and processing can depend on installed system voices and settings.
Practice reminders are optional local notifications. GeoNum requests notification permission only when you enable or test reminders.
Network access and third parties
The current GeoNum release includes its lesson content and reference data in the app and does not require a GeoNum backend or separate content download. It contains no advertising SDK and no analytics SDK. Apple or Google may process store-download, crash, and diagnostic information under their own terms and your device or store settings.
This public website
This Privacy Policy and the GeoNum support pages are hosted separately from the GeoNum app. The hosting and security providers for these pages may process ordinary network information such as an IP address, browser type, requested page, and request time to deliver the site, prevent abuse, and maintain security and reliability.
The website may use strictly necessary security cookies, including automated bot-management cookies provided by the hosting platform. The GeoNum operator does not use these pages for advertising, behavioral profiling, or cross-site tracking. This website processing does not change the app's local, account-free practice model.
Children
GeoNum is a general-audience language-practice app. It is not designed for infants, toddlers, or users who cannot independently understand and follow its practice instructions. Suitability is based on learning readiness rather than age alone. Some advanced lessons use adult-level contexts such as contracts, major purchases, finance, and business figures.
Children with the reading, listening, and speaking ability needed for the exercises may use GeoNum with guidance from a parent or legal guardian. GeoNum is not specifically directed to children under 13. A parent or guardian should supervise use of the device share sheet.
If you believe a child has sent personal information to the operator, email us so the request can be reviewed and information held by the operator can be deleted when appropriate.
Changes
If GeoNum later adds accounts, cloud sync, analytics, advertising, purchases, or remotely downloaded content, this policy and the store privacy disclosures will be updated before those features are released.
