Wobble Stack: 2 Player Duel (뒤뚱 쌓기) Privacy Policy

Effective: 2026-10-01 · Last updated: 2026-09-30

In one line

Wobble Stack collects nothing.

No sign-up, no internet connection, no ads, no analytics. It is an offline game two kids play together on one phone. Delete the app and everything is gone with it.

1. What information, and where

The app sends nothing to our servers. There is no way for it to — the app contains no networking code.

The app does not store any records on the device either. The result of a match disappears when the match ends. We do not ask for a name, age, birthday, photos, location, or any device identifier. There is not a single text-entry field anywhere in the app.

2. Permissions

The app asks for no permissions at all — not photos, camera, microphone, location, contacts or notifications. Sounds are made by the app itself.

3. What we do not do

• No ads (no third-party advertising SDK)
• No analytics or tracking (there is no code that measures usage)
• No camera, microphone, or location. Sounds are made by the app itself; nothing is recorded
• Nothing can be bought or paid for inside the app
• No connection to other people — no chat, no friends, no leaderboards
• No links that lead out of the app

4. Retention and deletion

We hold no information and the device keeps no records, so there is nothing to delete.

5. Children under 13 (US) · under 14 (Korea) · 15 and under (Japan)

This app is made for children. Because it collects no personal information, there is nothing that requires a parent's consent under COPPA (US) or the Korean and Japanese personal-information acts. In line with Apple's Kids Category rules, it contains no third-party advertising or analytics.

6. Parents' rights

We keep no information about your child, so there is nothing to access, correct, or delete. If you have a question, write to the address below and we will answer.

7. Contact

• Company: TwoStepsAhead Inc. (주식회사 투스텝스어헤드)

8. Changes

If this policy changes, we will update this page and the effective date. Any change that would start collecting information will be announced inside the app first and will not be switched on without a parent's consent.
