정통 사주 만세력 (Saju Calculator) — Last updated: June 15, 2026

1. Overview

정통 사주 만세력 ("the App") is a free Android four-pillars (saju) calculator developed by 강건한건강 ("we", "us"). This Privacy Policy explains how we handle information when you use the App.

2. Information We Collect

The App does not collect, store, or transmit any personal information to our servers. Birth date and time you enter are used only on your device to compute the saju chart and are never sent anywhere. The App is 100% offline with no user accounts and no server-side communication other than loading advertisements.

3. How It Works

All astronomical and saju calculations happen entirely on your device. No internet connection is needed to use the App, and nothing about you or your input is sent anywhere.

4. Third-Party Services

The App uses the following third-party service:

• Google AdMob — for displaying advertisements. AdMob may collect device identifiers (such as Advertising ID) and usage data to serve personalized or non-personalized ads. For more information, see the Google Privacy Policy.

5. Permissions

The App requests only internet access, which is used to load ads. The App does not use or request access to your location, microphone, contacts, camera, or files.

6. Data Storage

The App does not create user accounts and does not sync any data to the cloud. Uninstalling the App removes any cached AdMob data stored on the device.

7. Children's Privacy

The App is suitable for general audiences and is not directed at children under the age of 13. We do not knowingly collect personal information from children.

8. Changes to This Policy

We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated revision date.
