This policy reflects the current Android internal-test build. The iOS app is not yet released; this policy must be reviewed again before an iOS launch or any material feature change.
1. Service overview
Safe Journey Korea (안심동행) provides station search, route guidance, real-time train information where available, nearby-station suggestions, and transfer or destination alerts. No account is required.
2. Information handled
The app may handle the stations you select, route choices, app preferences, language settings, and alert state. Preferences and recent choices are stored on your device. Requests for real-time subway data pass through a Cloudflare Worker relay; the relay is designed not to create user profiles or store route histories.
3. Location
If you grant location permission, the Android app uses precise or approximate location to suggest up to three nearby stations. The coordinate is used for that request and is not directly sent to AdMob. You may deny permission and choose a station manually. Location is not used to confirm that you boarded a train.
4. Advertising and third-party services
One Google AdMob banner may appear beneath guidance controls on the home screen. No ad is shown while waiting, riding, transferring, or receiving destination alerts. Google Mobile Ads may process IP address (which may indicate approximate location), product interactions, diagnostics, and device or advertising identifiers for advertising, analytics, and fraud prevention. Consent and privacy choices are provided where required. Guidance remains usable if an ad is unavailable or consent is declined.
5. Retention, deletion, and sharing
On-device preferences remain until you clear app data or uninstall the app. The operator does not sell personal information and does not intentionally retain GPS coordinates or route history on its server. Technical service providers may process request metadata needed to provide and secure their services under their own terms. Ad-related handling follows Google's services and your consent choices.
6. Your choices and rights
You can revoke location and notification permissions in device settings, change ad privacy choices in the app where available, clear app data, or uninstall the app. Because the service has no account, the operator ordinarily has no account record to retrieve or delete. You may contact us with a privacy question or request.
7. Contact and changes
Privacy operator: Dosisoft. Email: seungyong.kim23@gmail.com. We will post material policy changes here and update the effective date. Store disclosures must be reviewed whenever the app, SDKs, permissions, or data practices change.
