Prompt Beacon Privacy Policy
Language: English
Effective Date: April 17, 2026
1. Introduction
This Privacy Policy describes how "Prompt Beacon" (hereinafter "the App") handles user information.
Provider/Controller: 松本和也 (Contact: kensyumi.app@gmail.com)
2. Our Core Commitment — No Personal Data Collected
Prompt Beacon is a developer-focused desktop tool for logging AI prompts locally on your device.
Our fundamental policy:
- All data is stored only on your device (local SQLite database)
- No cloud sync. Data never leaves your computer via the network
- No account or login required
- Works 100% offline — no internet connection needed at any time
- No personally identifiable information is collected, processed, or transmitted
3. Information We Collect
3.1 User-Input Information
The following data is stored on your device only. Nothing is transmitted externally.
- Log entries (prompt content, hashtags, app tag, result notes, status, timestamp)
- App settings (theme, language, etc.)
3.2 Information Sent Externally
None. This App does not transmit any data to external services.
4. Third-Party Services
The frameworks used to build this App (Tauri, React, etc.) operate locally and do not communicate with external servers at runtime.
The "Buy Me a Coffee" link in the app is an optional external link to buymeacoffee.com. Clicking it takes you to an external site, where that site's own privacy policy applies.
5. Data Storage and Retention
- Storage location: Local storage on your PC (SQLite database file)
- Retention period: Until you delete it or uninstall the App
- CSV export: Available at your option; exported files remain entirely under your control
6. Your Rights
- You can delete all logs at any time using the "Delete all logs" feature in the app
- Uninstalling the App will remove all local data from your device
7. Children's Privacy
This App is intended for developers and creators. Users under the age of 13 require parental consent.
8. Changes to This Policy
We will notify users of important changes in the app or on our website.
