Senior Cognitive Training Privacy Policy

Effective date: June 22, 2026

Senior Cognitive Training is a cognitive-activity tool that a caregiver (social worker, care worker, or family member) runs together with an older adult (coloring, spot-the-difference, learning Hangul). The app operates no server; all data, including elder profiles and activity records, is stored only in the device's local storage and is never transmitted externally. Hasegi Inc. manages information securely in compliance with applicable laws. This app is not a medical device, and activity records are not a medical diagnosis or assessment.

1. Purposes of Processing

Providing the cognitive-activity tool — managing elder profiles (name, etc.) so a caregiver can run 1:1 or across multiple devices; storing each elder's progress, difficulty level, and activity participation records (date, activity, time, result); storing settings (text size, voice speed, mode).
Advertising & operation (free Personal mode only) — ads via Google AdMob: banner, native, interstitial (on returning to the caregiver screen), and app-open (no ads on the elder's activity screens); managing iOS App Tracking Transparency (ATT) consent.
App sharing — when the caregiver taps Share, the OS share sheet sends an app description and store link to other apps. The sharing action is not stored or analyzed.

2. Information Collected & Methods

1) Entered by the caregiver and stored on the device

Senior Cognitive Training has no sign-up or login. To distinguish elders, the caregiver may enter the following, stored only in the device's local database (sqflite) and never sent to any server:

Elder's name (or nickname) — for on-screen identification
Birth year (optional)
Per-elder progress and per-domain difficulty level
Activity records — date, activity type, duration, result

The current version does not collect elder photos; the profile avatar is shown automatically using the first letter of the name and a color.

Caregiver (institution/family) responsibility: An elder's name is third-party information entered by the caregiver. The caregiver must obtain consent from the elder (or guardian) before entering it. The information is kept only on that device; in institutional use, manage devices appropriately (e.g., device lock) against loss or shared use.

2) App settings (stored on device)

Text size, voice-guidance speed, reduce-motion setting
Mode (Personal/Institution), institution subscription/license status and license key (SharedPreferences)

3) Automatically collected (third-party SDK, free Personal mode)

In free Personal mode, the included Google Mobile Ads SDK (AdMob) may automatically collect, to serve ads:

Advertising identifier (Android Advertising ID / iOS IDFA)
IP address
Device info (OS version, model, language, country, app version)
Ad interaction info (impressions, clicks)

This is processed under Google's privacy policy and may be sent to overseas servers (e.g., the US). See policies.google.com/privacy.

iOS users: On iOS 14+, Apple's ATT prompt appears once on first launch. The advertising identifier (IDFA) is used for personalized ads only if you allow tracking; if you decline, all features work normally and non-personalized ads are shown.

4) About ads

Personal (free): banner and native ads on the caregiver/home screen; an interstitial may appear when returning to the caregiver screen, and an app-open ad when reopening the app. No ads of any kind appear while the elder is doing an activity, and no full-screen (interstitial) ads during activities.
Institution (subscription or license) and subscribers: no ads at all.

5) In-app purchases (subscription)

Institution features are available via an in-app subscription through the Apple App Store or Google Play. Payment, renewal, and refunds are handled by the respective store; we do not collect or store your payment card details. Subscription status (active, expired, etc.) is stored on the device for purchase restoration and managed through your store account. The offline license key for institutions that need a tax invoice is verified on-device only and is not transmitted.

3. Retention

Item	Location	Retention
Elder name/birth year/progress/activity records	Device local storage	Until app or profile deletion
App settings (text/voice/mode/license)	Device local storage	Until app deletion
Advertising identifier & ad data	Google AdMob	Per Google's policy

Deleting an elder's card in the app removes that elder's info and records from the device. Uninstalling the app deletes all stored data, unrecoverably.

4. Provision to Third Parties

Senior Cognitive Training does not provide elder/caregiver information to third parties, except with prior consent or under a lawful request by authorities.

5. Outsourcing / Third-Party SDKs

Senior Cognitive Training runs no server and does not outsource processing. It includes:

Provider	Service	Policy
Google LLC	Google AdMob (Personal ads) / advertising ID · Google Play in-app billing	Google Privacy Policy
Apple Inc.	App Store distribution / ATT / in-app billing (StoreKit)	Apple Privacy Policy

Voice guidance is provided by the device's text-to-speech (TTS) and bundled audio; no personal data is transmitted in this process.

6. App Permissions

Internet (Personal, for ads; and for purchases): to load ads in Personal mode and to process in-app purchases. All activities work without internet; only ads are not shown.
App Tracking Transparency (iOS, optional): to check personalized-ad consent. All features work if declined.

Senior Cognitive Training requests no camera, microphone, location, contacts, photos, files, or notification permissions.

7. Your Rights

Delete an elder's card in the app to immediately remove that elder's info/records.
iOS: Settings → Privacy & Security → Tracking → turn off "Senior Cognitive Training".
Android: Settings → Google → Ads → "Reset advertising ID" or "Opt out of Ads Personalization".
Uninstall to remove all local data at once.

8. Destruction

Deleting an elder's card or uninstalling the app permanently removes the data from the device. As Senior Cognitive Training runs no server, no personal data is stored on any server.

9. Security Measures

Technical: all data is stored only in the device's local storage (app sandbox), blocking external access.
Minimization: only the minimum needed to identify elders and run activities.
Third-party SDK: only verified SDKs (Google AdMob) are used.

10. Protection of Elders/Children

Senior Cognitive Training is a tool a caregiver uses with an older adult. Elders do not enter identifiers themselves; names are entered by the caregiver with consent. Information of children under 14 is not collected; guardian supervision is recommended for home use.
