1. Overview
Drive Fusion ("we", "our", or "us") is a desktop application that allows you to manage multiple Google Drive accounts from a single interface. This Privacy Policy explains what information we collect, how we use it, and how we protect it.
Key principle: Drive Fusion is a local desktop app. Your files and credentials are never uploaded to our servers. All file operations happen directly between your device and Google's servers.
By installing and using Drive Fusion, you agree to the practices described in this Privacy Policy.
2. Information We Collect
Information stored locally on your device:
- Google Account email address — used to identify which account owns which files. Stored in a local SQLite database on your device.
- OAuth 2.0 refresh tokens — used to maintain access to your Google Drive without requiring you to log in repeatedly. Stored securely in your operating system's native keychain (macOS Keychain), never in plain text.
- File metadata cache — file names, sizes, MIME types, and modification dates are cached locally in a SQLite database to improve performance. This cache is periodically purged and can be cleared manually at any time.
- App preferences — settings such as language, view mode, and display preferences are stored locally using electron-store.
Information we do NOT collect:
- We do not collect your file contents
- We do not collect your Google Account password
- We do not transmit any data to our servers during normal app usage
- We do not use analytics, crash reporting, or telemetry services
- We do not track your usage behavior
3. Google API Data Usage
Drive Fusion uses the Google Drive API to provide its core functionality. Our use of Google user data is governed by the Google API Services User Data Policy, including the Limited Use requirements.
What Google data we access:
| Data | Purpose | Stored? |
|---|---|---|
| Google Account email | Display which account a file belongs to | Locally on your device only |
| Drive file metadata (name, size, type, dates) | Display files in the app interface | Locally cached, auto-purged |
| Drive file contents | Upload, download, preview operations initiated by you | Not stored; streamed on demand |
| Storage quota information | Display storage usage per account | Not stored; fetched on demand |
| File permissions | Share files when you explicitly request it | Not stored |
Limited Use Disclosure: Drive Fusion's use of information received from Google APIs will adhere to the Google API Services User Data Policy, including the Limited Use requirements. Specifically:
- We only use Google data to provide and improve the features visible to the user in Drive Fusion
- We do not transfer Google user data to third parties except as necessary to provide the app's features
- We do not use Google user data for advertising purposes
- We do not allow humans to read Google user data unless you have explicitly given permission, it is necessary for security purposes, or we are required to do so by law
OAuth scopes requested:
https://www.googleapis.com/auth/drive— required to list, upload, download, delete, move, and share files across your entire Drive, including files not created by this apphttps://www.googleapis.com/auth/userinfo.email— required to display your account email in the app
You can revoke Drive Fusion's access to your Google account at any time by visiting myaccount.google.com/permissions and removing Drive Fusion from the list of connected apps.
4. How We Use Your Information
Information collected is used exclusively to:
- Authenticate you with Google and maintain your session
- Display your Google Drive files within the app
- Perform file operations (upload, download, move, copy, delete, share) that you explicitly initiate
- Remember your app preferences between sessions
- Validate your Pro license (license key and device identifier only — see Section 6)
We do not use your information for marketing, advertising, profiling, or any purpose beyond operating the app.
5. Data Storage & Security
All data is stored locally on your device in the following locations:
- OAuth tokens — macOS Keychain (system-level encrypted storage). Never written to disk in plain text.
- File metadata cache — SQLite database in your app's local data directory (
~/Library/Application Support/Drive Fusion/). Automatically purged every 5 minutes in production; can be cleared manually in developer mode. - App settings — JSON file in app data directory, managed by electron-store.
Drive Fusion runs in Electron's sandbox mode with Content Security Policy enabled. The app cannot execute remote code or make unexpected network requests.
We do not operate servers that store your personal data. The only external network connections the app makes are directly to Google's APIs (googleapis.com) and to our license validation endpoint (for Pro users).
6. Third-Party Services
Google LLC — Drive Fusion communicates with Google Drive API and Google OAuth2. Your data is subject to Google's Privacy Policy.
LemonSqueezy (Pro license purchases only) — When you purchase a Pro license, your payment is processed by LemonSqueezy. We receive only a license key and your email address for license validation. Payment data (card numbers, billing address) is handled entirely by LemonSqueezy and subject to their Privacy Policy.
License validation — When the app validates your Pro license, it sends your license key and an anonymized device identifier to our license server. No Google data or file information is included in these requests.
We do not share your Google account data, file metadata, or any personal information with any third party beyond what is described above.
7. Your Rights & Choices
You have full control over your data:
- Revoke Google access — Visit myaccount.google.com/permissions to remove Drive Fusion's access to your Google account at any time.
- Remove an account — Use the "Log out" option in the app sidebar to disconnect any account. This deletes the stored token from your keychain and removes all cached data for that account.
- Clear all local data — Uninstalling Drive Fusion removes all app data from your device. Tokens stored in Keychain can be removed manually via the macOS Keychain Access app if needed.
- Request data deletion — Since we do not store your data on our servers, there is nothing to delete on our end. All data lives on your device and can be removed by uninstalling the app.
8. Children's Privacy
Drive Fusion is not directed at children under the age of 13. We do not knowingly collect personal information from children under 13. If you believe a child under 13 has provided us with personal information, please contact us and we will take steps to delete such information.
9. Changes to This Policy
We may update this Privacy Policy from time to time. When we do, we will update the "Last updated" date at the top of this page. For significant changes, we will notify users via an in-app notification or on our website.
Continued use of Drive Fusion after changes are posted constitutes your acceptance of the updated Privacy Policy.
