PassRun - Excavator Operator, hereinafter "the App", is a study app for the Korean excavator operator written examination. The developer takes your privacy seriously and complies with the Personal Information Protection Act of Korea and other applicable laws. This policy explains what information the App collects and uses.
The App requires no account or login and does not ask for personal data such as your name, email address or phone number in order to study.
Only when you choose to write and send an enquiry on the App's "Training" screen do we collect the information below. If you do not send an enquiry, no personal data is collected at all.
| Item | Details |
|---|---|
| Data collected | Name, phone number Email address, preferred region Enquiry type and message |
| How it is collected | Entered by you in the in-app form and submitted |
| Purpose | Replying to your enquiry, e.g. information about practical training centres |
| Retention period | Destroyed without delay once the consultation is complete |
| Consent | You tick the consent checkbox before submitting |
You may decline to give consent. In that case only the enquiry feature is unavailable; all study features continue to work normally.
The App serves Google AdMob ads (banner, interstitial, native, app open and rewarded). For ad delivery and fraud prevention, Google may automatically collect and process:
For details on Google's processing, see:
Personalised ads can be turned off inside the App — the "Allow personalized ads" switch on the Settings screen. On first launch the App shows this choice once; the default is on. You can change it in Settings at any time.
The developer entrusts processing to the following parties for enquiry handling and advertising.
| Processor | Entrusted work |
|---|---|
| Google LLC (Firebase / Cloud Firestore) | Storage and management of training-centre enquiries |
| Google LLC (AdMob) | Serving in-app advertising and measuring ad performance |
| PostHog, Inc. (PostHog Cloud US) | Storing and analysing the anonymous usage statistics in §4-1 |
Processors handle the data only within the scope of the entrusted purpose.
To improve question quality and run the service, the App collects the anonymous information below and sends it to Google Firebase and to PostHog. It contains nothing that identifies you personally, and the study data in §1 is never transmitted.
| Item | Details |
|---|---|
| Collected | Anonymous identifier (randomly issued, not linked to an account or name) Per-question correct/incorrect counts (which questions are missed most often) App usage events (screen views, ad impressions/clicks, etc.) App package name, operating system (Android/iOS), timestamp |
| Purpose | Analysing question errors and difficulty, feature improvement, service statistics |
| Retention | Until the statistical purpose is achieved (kept in a form that cannot identify individuals) |
Of the above, the product-analytics events are transferred and stored overseas as follows. The transferred information contains nothing that identifies you personally.
| Recipient | PostHog, Inc. (privacy@posthog.com) |
|---|---|
| Country | United States (PostHog Cloud US, us.i.posthog.com) |
| Items transferred | The items above — anonymous identifier, app usage events, app package name and platform |
| Purpose | Usage statistics and product analytics |
| Method | Sent from the App over encrypted communication (HTTPS) as each event occurs |
| Retention | Until the purpose is achieved (kept in a form that cannot identify individuals) |
This anonymous collection and the overseas transfer are always on, and the App has no switch to turn them off. Because only non-identifying information is collected, this notice takes the place of a separate consent step. If you want the collection or the transfer stopped, contact us at the address in §9; every study feature keeps working either way.
The developer does not sell or provide your personal data to third parties. Where you have requested an introduction to a training centre, the minimum information necessary for the consultation may be passed to that institution only after separately informing you and obtaining your consent.
You may at any time request access to, correction of, deletion of, or suspension of processing of your personal data. Contact us at the address below and we will act without delay. Study data stored on your device can be deleted by you directly from the App's settings.
The App is intended for national technical qualification study and does not knowingly collect personal data from children under the age of 14.
For any privacy-related enquiry, please contact us and we will respond without delay.
If this policy changes, we will give notice through an app update announcement or on this page.
