Privacy Policy

1. Scope

This policy applies to information handled by the Oneul Rhythm mobile app and by the Google AdMob advertising services included in the app.

Oneul Rhythm does not provide sign-in, user accounts, an operator-run server, or cloud synchronization.

2. Information stored only on your device

The following information that you enter or create while using the app is stored locally on your device:

• Rhythm names, start and end times, repeat days, reminders, and notes
• Completion records by date and the state of an active focus session
• App preferences such as the default reminder

This information is used for Today, rhythm management, local notifications, iOS Live Activities, and Android progress notifications. It is not transmitted to the Oneul Rhythm operator.

3. Information the advertising service may process

We use the Google Mobile Ads SDK and User Messaging Platform SDK to provide limited banner advertising in the free version. Google may automatically collect or share the following information for advertising, analytics, and fraud prevention:

• IP address and approximate location inferred from it
• Product interactions such as app launches, taps, and ad views
• Diagnostics and performance information such as crash logs, launch time, hangs, and energy use
• Device or account-related identifiers, including advertising and app-scoped identifiers
• Advertising data such as ads that were shown

The exact processing may vary by device, operating system, region, consent choice, and Google advertising settings. See the Google Privacy Policy and How Google uses advertising technologies for details.

4. Advertising consent and choices

Where required by law or Google policy, Google presents consent choices for advertising data. When available, you can review or change those choices in Settings → Privacy → Ad privacy choices.

You can also reset or delete your advertising ID in your device settings. Depending on your choices, personalized, non-personalized, or limited ads may be served.

5. Retention and deletion

Information stored on your device may remain until you delete the related rhythm in the app, clear app data through the operating system, or uninstall the app. The Oneul Rhythm operator cannot access, restore, or remotely delete this local information.

Advertising information processed by Google is retained and deleted under Google policies and your Google and device privacy settings.

6. Third parties and security

The Oneul Rhythm operator does not sell or provide your rhythm names or notes to third parties. Information described above may be processed by Google when advertising features are used.

Local information is kept in the app storage area provided by the operating system. According to Google's published documentation, data collected by the Google Mobile Ads SDK is encrypted in transit.

7. Changes to this policy

We may update this policy when app features, included SDKs, or applicable requirements change. Material changes will be reflected on this page with an updated effective date.
