Strength Log — Last updated: June 7, 2026

1. Overview

Strength Log ("the App") is a free Android strength-training set logger 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. It is a self-contained workout logger with no user accounts and no server-side communication.

Your workout entries (exercise names, weights, reps, dates) are stored only on your device using AsyncStorage. Uninstalling the App removes all of this data.

3. 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.

4. Permissions

The App requires only internet access (to load ads). It does not request access to your contacts, location, camera, microphone, or storage.

5. Data Storage

All workout data is stored locally on the device. There is no cloud sync, no backup, and no account system. Uninstalling the App removes all locally stored data and cached AdMob data.

6. Children's Privacy

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

7. Health Disclaimer

The App is a logging tool for self-directed strength training. It is not a medical device, does not diagnose any condition, and is not a substitute for professional medical advice. Consult a healthcare professional before starting any new exercise program.

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.
