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.

• Settings → Privacy & data → RESET PRACTICE HISTORY removes practice history, progress, and paused sessions.
• DELETE PRACTICE DATA & REPORTS 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.

Your operating system may include app-local data in its normal device backup, according to your backup settings.

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 Settings → Help & support → Saved content reports → EXPORT SAVED REPORTS, the system share sheet opens and you select the destination. Information shared that way is governed by that destination’s privacy practices.

Speech, microphone, and notifications

Spoken prompts use the device operating system’s text-to-speech service. GeoNum does not request microphone access or record the user's voice. It does not store, upload, transcribe, analyze, profile, or automatically score spoken responses, and it does not operate a speech server. Speaking prompts simply invite the user to repeat aloud and evaluate their own practice. The availability of spoken prompts depends on installed system voices and settings.

See → Say is self-assessed. Hear → Type compares typed answers with the reference on your device; this is not microphone recording or speech recognition. For offline playback, use a compatible installed English system voice and test it once in airplane mode.

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. GeoNum is a paid-upfront app with no in-app purchases or subscriptions. Apple handles App Store purchases and distribution and may process store-download, crash, and diagnostic information under its 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 using OpenAI Sites. OpenAI and the infrastructure and security providers used by the hosting service 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.

Email inquiries

If you contact customer support, Hedeonix receives the email address, message, and any attachments you choose to send. This information is used to answer the inquiry, investigate the reported issue, protect the service, and meet applicable legal obligations. It is kept only as long as reasonably necessary for those purposes. Do not send passwords, financial account numbers, government identifiers, or other sensitive information.

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, in-app purchases, or remotely downloaded content, this policy and the store privacy disclosures will be updated before those features are released.
