version 1.3.0 — 2026-10-04

This Privacy Policy describes how Nagara (the "App") handles user information.

1. Information We Collect

The App automatically collects the following information:

Item	Sent to	Purpose
Feature interaction counts, anonymous device-side UUID, session ID, app version, macOS version, error category	Google Analytics 4	Product improvement and bug detection
Crash reports (stack trace, device model, macOS version, app version, anonymous installation ID)	Firebase Crashlytics	Diagnosing and fixing crashes

2. Information We Do Not Collect

The App never transmits any of the following:

Personal information such as Apple ID, name, or email address
Watch history, bookmarks, or favorites
AI analysis results or chat conversation content
API keys (Claude / OpenAI / Gemini / DeepSeek) — these are stored locally in the macOS Keychain and are never sent anywhere other than directly to the user's chosen LLM provider

3. Third-Party Providers

Privacy policies of the third-party services used by the App:

4. Opting Out

From version 2.2.0, you can turn off these anonymous statistics and crash reports in the app under “Settings > Privacy”; your choice is kept across launches. Earlier versions do not provide such a setting. Only feature usage and error categories are sent — your watch history, bookmarks, AI analysis results, chat content and API keys are never included. If you use an earlier version and would like collection stopped, or have any questions, please contact us at info@cavemen.jp.

5. Data Retention

Data retention periods follow the policies of each third-party service (Google Analytics: 14 months; Firebase Crashlytics: 90 days).
