Privacy Policy for Combine Google Drive

1. Introduction & Ownership

Welcome to the Privacy Policy for Combine Google Drive (also referred to as Unified Drive, or the "Application"), owned, engineered, and maintained by kbnai.co ("we", "us", or "our"). Our official web domain is https://kbnai.co.

We fundamentally believe that user data privacy, file confidentiality, and intellectual sovereignty are non-negotiable rights. This Privacy Policy details our operational architecture, data handling practices, and our strict adherence to Google's API Services User Data Policy.

2. Google API Services User Data Policy & Limited Use Disclosure

Combine Google Drive integrates with Google Drive APIs to enable you to access, browse, upload, download, and organize files stored across your Google Drive accounts.

Specifically, in compliance with Google Limited Use requirements:

• No Transfer to Third Parties: We do not transfer, sell, disclose, or relay information received from Google APIs to any external third party, commercial partner, or advertising network. All API communication is strictly between your Mac client and Google's official servers.
• No Advertising: We do not use or transfer user data from Google APIs for serving advertisements, personalized marketing, interest-based tracking, or retargeting campaigns.
• No Machine Learning / AI Model Training: Information received from Google APIs—including file names, folder structures, file content, documents, or metadata—is NEVER used to train, fine-tune, improve, or evaluate any artificial intelligence, machine learning, or large language models.
• No Human Inspection: No human at kbnai.co or any third party has access to or will inspect your Google Drive files or metadata. Reading of file data occurs only programmatically upon your direct client command (e.g., when you request to view or download a file on your device).

3. Information Handled & Local Storage Architecture

Combine Google Drive is designed as a client-side macOS application. Below is an exhaustive breakdown of all data elements handled:

4. Third-Party Data Sharing & Intermediate Servers

We do not operate intermediate servers for Combine Google Drive.

Unlike traditional cloud aggregators that require users to route their confidential drive contents through centralized cloud servers, Combine Google Drive functions like a terminal (such as cURL, rsync, or Git). All API requests are originated on your local hardware and resolved directly with Google's servers.

We do not share, sell, rent, monetize, or disclose any personal data or file contents to third parties, data brokers, or advertisers under any circumstances.

5. User Control, Data Retention & Revocation

You retain complete, sovereign control over your data, files, and account authorizations at all times:

• Revoking Google Access: You can disconnect and revoke Combine Google Drive's access to your Google account at any moment through Google's official security center:
  https://myaccount.google.com/permissions
• Local Data Deletion: To completely wipe all offline cached files and folders, delete the local working directory located at:
  ~/UnifiedDrive on your Mac.
• Credential Removal: Signing out of any account in Combine Google Drive permanently deletes stored OAuth tokens from your local macOS Keychain.

6. Security Architecture & Safeguards

We adhere to rigorous industry standards to safeguard user interactions:

• End-to-End Transport Security: 100% of network communication with Google APIs is enforced over TLS 1.3 / HTTPS encryption.
• Standard OAuth 2.0 PKCE: We use industry-standard Proof Key for Code Exchange (PKCE) OAuth 2.0 flows, preventing authorization code interception.
• Operating System Isolation: Credentials are protected using native macOS Keychain sandboxing to safeguard against unauthorized local process inspection.
• Reversible Trashing: The application does not perform permanent hard-deletions on Google Drive. All deletions move items to Google Drive's native Trash folder with an explicit user confirmation prompt.

7. Children's Privacy

Our software and website are not directed toward children under 13 years of age. We do not knowingly collect or solicit personal information from children.

8. Updates to this Policy

We may occasionally update this Privacy Policy to reflect technical improvements, new app capabilities, or evolving legal and Google API guidelines. Any revisions will be published immediately on this page (https://kbnai.co/privacy.html) with an updated "Last Updated" timestamp.
