Privacy Policy for ChatShuttle Nexus

Effective Date: January 30, 2026

TL;DR — Your Data Stays Yours

  • Your chat data is downloaded from your Google Drive
  • Index and cache stay on your local computer
  • We do not have a server that stores your data

Introduction

ChatShuttle Nexus ("Nexus") is an open-source Desktop Skill designed to work as a companion to the ChatShuttle Chrome Extension. This policy specifically covers the privacy practices of the Nexus application.

1. Data Collection

This application (ChatShuttle Nexus) accesses Google User Data to provide its core functionality. Specifically, we access:

  • Google Drive Files: We access only the files and folders within the ChatShuttle_Memories folder (specifically index.voy and metadata.json). We do not index, read, or process any other personal files in your Google Drive.
  • Google User Identity: We access your email address solely to verify your account identity during the OAuth login process.

Disclosure on drive.readonly Scope

Unlike our browser extension which creates files, this Desktop application acts as a "Reader" for your existing archives. To read these specific files created by another client, Google requires the https://www.googleapis.com/auth/drive.readonly scope.

Important: Although this scope technically allows read access to your Drive, our codebase is strictly programmed to filter and access ONLY the ChatShuttle_Memories folder.

2. Data Usage

How we use, process, and handle the Google User Data we access:

To Sync Your Memory Index

We use the Google Drive API to download the search index (index.voy) and metadata files (metadata.json) from your cloud archive to your local machine. This allows you to perform fast, offline searches of your chat history.

Local Processing Only

All data processing (vector search, keyword matching, result ranking) happens locally on your computer's CPU/memory. We do not send your chat content or search queries to any external server.

3. Data Storage

Your data is stored in two locations:

  • Google Drive (Cloud): Your master archive remains in your own Google Drive.
  • Local Device (Cache): A temporary copy of the search index is stored in your local user directory (~/.chatshuttle/cache) for performance. This data never leaves your device.

We do NOT operate a database that stores your chat content or personal information.

4. Data Protection

We employ industry-standard security measures to protect your information:

  • Encryption in Transit: All data transferred between Google Drive servers and your local machine is encrypted using Transport Layer Security (HTTPS/TLS).
  • Local Security: Detailed chat history is stored only on your local file system, protected by your operating system's user permissions. We do not maintain any external databases of your sensitive information.

5. Data Retention and Deletion

You retain full control over your data lifecycle:

  • Retention: Local cache files exist on your device only as long as you use the application. The master copies in Google Drive are retained according to your own Google Drive settings.
  • Deletion: You can delete the local data at any time by manually removing the cache folder (~/.chatshuttle) on your computer. You can also delete the master archives in Google Drive by removing the ChatShuttle_Memories folder.

6. Data Sharing

We do not sell, trade, or share your Google User Data with third parties.

There are no third-party services involved in the core search loop of this application.

7. AI Training

We do NOT use your data to train AI models. Your conversations remain private and are only formatted for your own personal use with local AI agents.
