Privacy Policy

Daily Timeline Log — Last updated: July 4, 2026

1. Overview

Daily Timeline Log ("the App") is a free Android app developed by 강건한건강 ("we", "us"). It lets you record your day as a chronological timeline of time-stamped entries with categories, emoji, and search, and export your log as a CSV file. 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. It has no user accounts and no server-side communication other than loading advertisements (see below). All data you create (timeline entries, categories, and notes) is stored locally on your device only.

3. Notifications

With your permission, the App may schedule local reminders on your device. These are generated entirely on-device and are not sent through or stored on any server.

4. Biometric Lock

The App can optionally lock access using your device's biometric authentication (fingerprint or face). Biometric verification is performed entirely by your device's operating system; the App never receives, stores, or transmits your biometric data.

5. Third-Party Services

The App uses the following third-party service:

• Google AdMob — for displaying advertisements. The App shows a banner, a full-screen ad at natural breaks, and an app-open ad on launch. 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.

6. Data Storage

The App does not create user accounts and does not sync any data to the cloud. All data stays on your device. Uninstalling the App removes all stored data along with any cached AdMob data.

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.
