# CloudBox > CloudBox is an iOS app that unifies the cloud storage accounts you already own — Google Drive, Microsoft OneDrive, Dropbox, and NAS/network drives — into a single library. Browse every file in one place, see how full each account is, find duplicates across accounts, free up space, and upload automatically to whichever cloud has the most room. CloudBox is built by MONI TECHNOLOGY CO., LTD. Status: **available now** on the App Store — https://apps.apple.com/us/app/cloudbox-free-storage/id6792605194 ## What it does - **Unified storage** — every connected cloud account in one library; browse photos, videos and documents without switching apps. - **Smart upload** — automatically picks the account with the most free space so uploads don't fail on a full drive. - **Clean & organize** — finds duplicate files and oversized videos across accounts, then reclaims the space. - **Storage analytics** — total used vs. available across all clouds, broken down by account and by file type. - **Duplicate cleaner** — groups duplicates, suggests the best copy to keep, always asks before deleting. - **Secure & private** — official OAuth sign-in for every provider; files move between your device and your own accounts. ## Privacy model (important) CloudBox is a **client app, not a storage service**: - File contents are **never stored on CloudBox servers**. Transfers happen directly between the device and the user's own cloud accounts. - Sign-in uses each provider's official OAuth 2.0 flow. CloudBox never sees or stores passwords. - OAuth tokens are stored in the iOS Keychain on the device. - Google user data handling adheres to the Google API Services User Data Policy, including Limited Use requirements. - No advertising profiles, no selling data, no using file content to train AI models. - Users can revoke access anytime in-app or from the provider's security settings. ## Supported providers Google Drive, Microsoft OneDrive, Dropbox, NAS / network drives (standard protocols). More planned based on demand. ## Pricing Free to download, with a free tier (connect accounts, browse unified library). Advanced features such as bulk duplicate cleaning and smart upload rules are a paid upgrade; prices are shown in the App Store. ## Key pages - [Home](https://mcloudbox.com/): product overview, features, FAQ, download link - [App Store](https://apps.apple.com/us/app/cloudbox-free-storage/id6792605194): download CloudBox for iPhone - [Privacy Policy](https://mcloudbox.com/privacy): data handling, Google API disclosure, deletion - [Terms of Service](https://mcloudbox.com/terms): licence, acceptable use, subscriptions ## Contact - Website: https://mcloudbox.com - Support: support@moniai.app - Company: MONI TECHNOLOGY CO., LTD.
