## Privacy Policy

Last updated: July 8, 2026

Hajime Nakamura ("I", "me", "my") built the Time Manage app as a free app. This SERVICE is provided at no cost and is intended for use as is. This page informs you of my policies regarding the collection, use, and disclosure of information for anyone who uses this app.

**Information You Create**

The times, tags, and records you create in the app are stored locally on your device. This content is not transmitted to me and is not stored on my servers.

**Third-Party Services**

The app uses third-party services provided by Google that may collect information to deliver advertising, analytics, and diagnostics. These services, and the kinds of data they may process, are:

*   **Google AdMob** (advertising): displays ads in the app. AdMob may collect and use device information and identifiers — including the advertising identifier (IDFA), IP address, and usage data — to deliver and measure ads, and, with your permission, to personalize ads.
*   **Google Analytics for Firebase** (analytics): collects app usage and event data so I can understand how the app is used and improve it.
*   **Firebase Crashlytics** (diagnostics): collects crash and error reports so I can find and fix problems.
*   **Firebase Performance Monitoring** (diagnostics): collects performance data, such as app start time and network request timing.

For details on how Google processes this data, see Google's Privacy Policy: https://policies.google.com/privacy . You can control Google ad personalization at https://adssettings.google.com .

**App Tracking Transparency (Advertising Identifier / IDFA)**

On first launch, the app asks for your permission to track you across apps and websites owned by other companies (Apple's App Tracking Transparency). If you do not allow tracking, the advertising identifier (IDFA) will not be used to track you; ads may still be shown, but they will be less personalized. You can change this choice at any time in iOS **Settings → Privacy & Security → Tracking**.

**Log Data**

When an error occurs, the third-party services above may collect log data on your device. This may include your device's IP address, device name, operating system version, the app's configuration, the date and time of use, and other statistics.

**Cookies / Identifiers**

The app itself does not use cookies. However, the third-party libraries used for advertising and analytics may use identifiers to collect information and improve their services.

**Security**

I value your trust in providing your information, and I strive to use commercially acceptable means to protect it. However, no method of transmission over the internet or method of electronic storage is 100% secure, and I cannot guarantee absolute security.

**Links to Other Sites**

This Service may contain links to other sites that I do not operate. I strongly advise you to review the privacy policy of any third-party site you visit. I have no control over, and assume no responsibility for, the content or privacy practices of any third-party sites or services.

**Children's Privacy**

This Service is not directed to children under 13, and I do not knowingly collect personal information from children under 13. If you believe a child has provided personal information, please contact me and I will delete it.

**Changes to This Privacy Policy**

I may update this Privacy Policy from time to time. Changes are effective when posted on this page. You are advised to review this page periodically.

**Contact**

If you have any questions or suggestions about this Privacy Policy, please contact me through the app's support page on the App Store.
