PassRun - Landscaping Technician Exam ("the app") is a study app for the Korean Landscaping Technician written exam. We value your privacy and comply with applicable laws including the Korean Personal Information Protection Act. This policy explains what the app collects and how it is used.
The app has no sign-up or login, and has no feature that asks for your name, email, phone number or any other personal information.
To improve question quality and operate the service, the app sends the following anonymous information to Google Firebase and PostHog. It contains nothing that identifies you personally.
| Item | Details |
|---|---|
| Collected | A randomly generated anonymous identifier (not linked to any account or name) Per-question right/wrong aggregates (which questions are missed often) App usage events (screen usage, ad impressions/clicks) |
| Purpose | Question error/difficulty analysis, feature improvement, service statistics |
| Retention | Until the statistical purpose is fulfilled (kept in non-identifiable form) |
This anonymous collection is always on and the app has no switch to turn it off. Because only non-identifying information is collected, this notice takes the place of a separate consent step. If you want the collection stopped, contact us at the address below; study features remain fully available either way.
The app shows Google AdMob ads (banner and interstitial). Google may automatically collect and process the following to serve ads and prevent fraud:
Personalized ads are served only with your consent. On first launch the app asks whether to personalize ads; on iOS, only if you choose Allow does the App Tracking Transparency (ATT) system prompt appear, and the IDFA is accessed only when you grant it. Every feature stays fully available either way — if you decline, ads are simply non-personalized. For users in the EEA and the UK, GDPR consent is collected separately through Google's User Messaging Platform (UMP).
You can turn off personalized ads at any time in the app (Settings → Ads → Personalised ads), or limit them in your device settings (Android: Settings → Google → Ads / iOS: Settings → Privacy & Security → Tracking).
The app can send one study reminder a day. This is a local notification scheduled entirely on your device — it is not a server push, and no information leaves your device for it. It works only if you grant the system notification permission, and you can turn it off at any time in the app (Settings → Notifications → Daily study reminder).

| Item | Details |
|---|---|

| Transferred data | Anonymous identifier, app usage events (screen usage, study progress, ad impressions) |

This transfer takes place at all times and the app has no switch to stop it individually. To request that it stop, contact us at the address below; study features remain fully available either way.
The transfer constitutes processing delegation necessary to provide and improve the service. Under Article 28-8(1)3 of the Personal Information Protection Act of Korea, it is carried out by disclosing the transferred items, country, timing, method, purpose and retention period in this policy — no separate consent is obtained for each transfer.
We do not sell or provide your personal information to third parties.
You may request access, correction, deletion, or suspension of processing at any time via the contact below. Locally stored study records can be deleted directly in the app settings.
The app is intended for national technical qualification study and does not knowingly collect personal information from children under 14.
Changes will be announced via app updates or this page.
