Privacy Policy

1. Data Collection and Storage

GGMemo is committed to protecting your privacy. We offer two modes of operation with different data handling approaches:

Basic Mode (No Sign-in)

  • All data is stored locally in your browser
  • Text memos with titles (up to 100 characters)
  • Record creation timestamps
  • No data is transmitted to our servers
  • Data can be exported in Markdown format

Session Mode (With Google Sign-in)

  • Match results (Win/Lose)
  • Performance ratings (1-5 stars)
  • Session titles and detailed notes (up to 300 characters)
  • Data is stored in Firebase and synced across your devices
  • Google authentication information (email, display name, profile photo)
  • Data can be exported in Markdown format

When installed as a Progressive Web App (PWA), the app utilizes caching through Service Workers to enable offline functionality and enhance performance.

2. Data Control

You have full control over your data:

  • Basic Mode: Delete data by clearing your browser's local storage or individual memos
  • Session Mode: Delete data by removing sessions or deleting your account entirely
  • Export your data anytime in Markdown format for your records
  • Request account deletion at any time (Session Mode)

We strongly recommend regularly exporting your data as a backup, especially before clearing browser data or deleting your account.

3. Third-Party Services

Current Services

5. Data Security

We take the security of your data seriously, but there are important limitations to be aware of:

  • Basic Mode: Data security depends on your browser's security features

In the event of a security breach or data loss, our ability to respond may be limited. We strongly encourage you to:

  • Regularly export your important data
  • Avoid storing sensitive personal information in your memos

By using GGMemo, you acknowledge and accept these limitations. We cannot accept liability for any damages resulting from data breaches, service disruptions, or other security incidents beyond our reasonable control.
