No Turning Back (켠김에끝까지)

Last updated: September 30, 2026

GonggamStudio ("we", "our", or "us") operates "No Turning Back" ("App"), a game where you play through a chain of minigames to the end.
This privacy policy describes what information the App collects and how it is used.
The App has no sign-up or login screen.

1 Information We Collect

The App collects the following information.

Ranking data – the nickname you choose, the round you reached, your score, whether you cleared every round, and the time of the record
Anonymous account ID – a random value the App creates automatically to tell ranking records apart per device (Firebase Anonymous Authentication). It is not linked to your name, email or phone number.
Device identifiers such as the advertising ID (Android advertising ID; on iOS, the IDFA only if you allow tracking), approximate location (based on IP), app interactions, crash logs and diagnostics – collected through Google AdMob when serving ads

2 How We Use Information

We use the information only for the following purposes.

Show the global rankings (all-time, monthly and Daily Challenge) and calculate your rank
Serve rewarded ads, confirm rewards and measure ad performance (Google AdMob)

3 Publicly Visible Information

Your nickname, the round you reached, your score and whether you cleared every round appear in the rankings and are visible to other users.
Please do not use your real name, contact details or anything else that identifies you as your nickname.

4 Third-Party Services

The App uses the following services, and their privacy policies also apply.

Google Firebase (Anonymous Authentication, Cloud Firestore) – stores the anonymous account ID, nickname and ranking records
Google AdMob (ads and ad personalization) – device identifiers such as the advertising ID, approximate location, app interactions, crash logs and diagnostics

5 Information Stored on Your Device

Game records, Daily Challenge results and sound settings are also stored on your device.
If Google backup is turned on for your Android device, these records may be included in your device backup.

6 Motion Sensors

Some minigames are controlled by tilting your device. The App reads your device's motion sensor values only to control the game.
Sensor values are not stored or transmitted.

7 Sharing Results

Tapping the share button opens your device's share screen. The shared text contains the round you reached, a per-round result chart and a link to install the App. Your nickname is not included.
The text is sent only to the app you choose, and from then on that app's policy applies.

8 Retention and Deletion

Ranking records are kept while the service is operated.
To have your ranking records deleted, email us using the button below and include the nickname shown on the App's title screen. We will delete them without delay once confirmed.
You can reset your advertising ID or turn off personalized ads in your device settings (Android: Settings → Google → Ads; iOS: Settings → Privacy & Security → Tracking).
