StoneStory — Privacy Policy

Last Updated: 2026-04-15

1. Overview
#

StoneStory, developed by QQder339, is an immersive reading and character simulation app based on the classic novel “Dream of the Red Chamber.”

In short: We do NOT collect, store, or transmit any of your personal data to external servers.

2. Data We Do NOT Collect
#

This app does not collect:

  • Personally Identifiable Information (name, email, phone number)
  • Location data
  • Device identifiers
  • Usage analytics or tracking data

3. Locally Stored Data
#

The following data is stored strictly on your device and never transmitted externally:

  • Traveler Profile: The name, personality traits, speech style, background, and optional avatar image you configure in Traveler Mode
  • Interface Preferences: Your selected display language (Traditional Chinese / English / Japanese) and chosen offline AI model
  • Downloaded Content: Character portraits and scene images cached after you view them in the app
  • Offline AI Model: The Qwen 2.5 model file you’ve chosen to download (stored in an App Group container for in-app use only)

4. Third-Party Services
#

This app does NOT use any third-party analytics or advertising frameworks (No Google Analytics, No Facebook SDK, No Ads).

5. Network Access
#

Core reading and simulation features work fully offline and require no network connection. The following features initiate network requests only when you explicitly trigger them:

  • Downloading Character Portraits / Scene Images: The first time you view a character or scene, the app fetches the corresponding image from a public CDN and caches it locally
  • Downloading the Offline AI Model: When you choose to download the Qwen2.5 model in Settings, the app fetches the file from the model’s public release source
  • External Links: Opens the system browser when you tap relevant links

These network requests transmit only the URL of the file you’ve chosen. No personally identifiable information is attached, and no data is collected in return.
