Privacy Policy

One Path (한붓그리기) · Effective 18 September 2026 · 한국어

One Path does not collect your personal information. There are no accounts, no sign-in, and no servers. All game progress is stored only on your device. The app does show ads, and the ad provider (Google) collects information separately in order to serve them. That scope is described below.

1. What the app stores on your device

The following is kept only on your device and is never transmitted anywhere. Deleting the app deletes it.

ItemDetail
ProgressHow far you got on each seed, and your best level
Puzzle cachePre-generated boards. Generation is deterministic, so this is purely a cache
Skill & tier pointsNumbers used for difficulty estimation and tier calculation
Challenge recordsSpeedrun completion times
SettingsCurrent seed, tutorial state, last hint time, ad pacing, ad-free purchase flag

None of this includes personally identifiable information — no name, email, phone number, location, contacts, or photos.

2. Advertising (Google AdMob)

The app serves interstitial and rewarded ads through Google AdMob. Google and its partners may collect and use the following to serve, measure, and protect against fraud in advertising:

This collection is governed by Google's policies, and the developer of this app does not have access to that data. The developer only sees aggregated revenue and impression statistics in the AdMob console, which contain no personally identifiable information.

See How Google uses information from sites or apps that use our services and the AdMob data disclosure for details.

Consent and your choices

3. Payments

In-app purchases such as ad removal are handled by the Apple App Store or Google Play. Payment details are handled by those stores; this app never receives or stores card numbers or any payment information. The app only asks the store whether a purchase exists and caches that answer on the device.

4. Children

This app is not directed at any particular age group and does not knowingly collect personal information from children. If a child uses the device, we recommend that a guardian turn off ad personalisation in the device settings.

5. Retention and deletion

Everything the app stores lives locally on the device. Deleting the app deletes it. The developer retains no user data, so there is no separate deletion request process. Access and deletion of advertising data follow Google's policies.

6. Changes

If this policy changes, this page is updated and the effective date at the top is revised. Significant changes are also announced inside the app.
