채움작명 Privacy Policy

Effective date: August 26, 2026

1. Overview

채움작명 (the "App") is provided by Zero One Studio. This policy explains what information the App handles and how.

2. Information we collect

We do not collect any personal information — no name, email, contacts, location, photos, or advertising identifiers. In-app data is stored only on your device and never transmitted.
The App operates no server. The surname, birth date, birth time and gender you enter, along with the Saju, name candidates, favorites and settings computed from them, are kept only in on-device storage and are never transmitted. There is no account or sign-in, and no ads or analytics tools are included. Deleting the App also deletes this data, and the studio cannot restore it. To move to another device you export and import a backup file yourself in Settings; that file also stays on your device. In-app purchases are handled by Google Play and the App stores only your entitlement locally — the studio never receives payment details such as card numbers. The App is not directed at children under 14 and does not process their personal information. When used as a mini app inside the Toss app, the following also applies. Toss (Viva Republica) collects mini-app visit, session and screen-view records for platform operation under its own privacy policy; the App does not put the surname, birth date, names or other values you enter into those records. A copy of your inputs, favorites and settings is also kept in on-device storage provided by the Toss app and is deleted with the Toss app. Purchases made in the Toss app are processed by Toss and recorded in your Toss account; the studio never receives payment details.
