Dockundock Defense Privacy Policy

Applies to version 1.0
Operator: YANGSONG Inc. (주식회사 양송)

Dockundock Defense is an orbital defense game where you protect a planet with drones that dock and undock. This policy states plainly what the app does with your information.

A Korean version of this policy is available at yangsong.co.kr/2026/09/dockundock-defense.html

Summary

Your game progress is stored only on your device and is never sent to the developer. The developer cannot receive, store or see it. This app has no developer server and no accounts.

The app has no ads, no payments, and no usage-statistics or error-reporting tools. The app's own code sends nothing over the internet.

However, the game engine the app is built with (Unity) may send device specifications and engine diagnostics to Unity Technologies. See What the Unity engine sends below.

What the app stores on your device

  • Game progress — cleared stages, star ratings and best records per stage, stage results (your drone and parts setup for that run)
  • Growth and currencies — account level and experience, currencies, research levels, part levels, boxes and keys
  • Energy — remaining energy and the times used to calculate recharge (based on your device clock)
  • Daily goals — progress, whether rewards were claimed, number of days played
  • Settings — sound, particle and damage-number settings, whether you have seen the tutorial, and whether you accepted this policy

This data is kept in app-private storage that other apps cannot read, and it is not sent to the developer. The app never asks for or stores anything that identifies you, such as your name, email, phone number or location.

What leaves your device

1. What the app sends — nothing

The app's code has no feature that sends data over the internet. The only internet use is the link that opens this policy; tapping it opens this page in your device's web browser.

2. What the Unity engine sends

The app is built with the Unity engine. To improve the engine, Unity may send device specifications (device model, operating system version, CPU, GPU and memory, screen resolution, language and similar) when the app starts, and diagnostic information when the engine encounters an error, to Unity Technologies.

Your game progress and anything that identifies you are not included. Unity's practices: unity.com/legal/privacy-policy

When data leaves by your choice

  • Android automatic backup — if Google Backup is on, your game progress and settings may be backed up to your own Google account. This is an Android feature and the developer cannot access it.

What the app does not do

  • It does not send your game progress to the developer.
  • It does not create accounts or require sign-in.
  • It does not show ads or use the advertising ID.
  • It does not take payments.
  • It does not use usage-statistics or error-reporting tools (such as Firebase).
  • It does not access location, contacts, the camera, the microphone or photos.
  • It does not sell data.

Deleting your data

  • Everything on the device — uninstalling the app, or Android Settings → Apps → Dockundock Defense → Storage → Clear data, deletes it immediately.
  • The Android automatic backup copy — managed and deleted in your own Google account's backup settings.

The developer keeps no separate copy. There is no server behind this app, so there is nowhere for the data to be received and held.

Age

The app never asks for, verifies or collects your age.

Permissions

  • Internet — used by the Unity engine (item 2 above) and for the link to this policy. The app's code sends no data over the internet.

The app does not request location, camera, microphone, contacts, photos or storage permissions.

Changes

If what the app does with information changes (for example, if ads or usage statistics are added), this policy is updated before the change ships. Changes are recorded here with their dates.
