1. Introduction
BJJ Diary (the "App") is an application for managing Brazilian Jiu-Jitsu training records.
This Privacy Policy explains how user information is handled within the App.

2. Personal Information Collection
The App does not collect any personal information. There is no account registration,
login, or membership functionality.

3. Data Storage
All data created in the App (journal entries, notes, drill lists, competition records,
settings, etc.) is stored solely on your device.

Specifically, the following data is stored locally:
• Training journal entries
• Drill lists
• Notes
• Competition records
• User settings (category, belt color, stripes, weight class)

4. Data Transmission
The App does not transmit any user data to external servers or cloud services.
All data remains on your device, and the App functions fully without an internet connection.

5. Analytics & Advertising
The App does not use analytics tools such as Google Analytics or any advertising services.
We do not track user behavior or display advertisements.

6. Data Deletion
Since all data is stored on your device, uninstalling the App will completely delete all data.
Individual data items (journal entries, notes, etc.) can be deleted from within the App.

7. Security
The App relies on your device's built-in security features (iOS Data Protection,
Android encryption, etc.) to protect your data.

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

9. Changes to This Policy
This Privacy Policy may be updated without prior notice. If significant changes are made,
we will inform you through the app update notes.
