Crosync Drop & Crosync Hub · Updated 25 October 2026 / 更新于 2026 年 10 月 25 日 / 2026年10月25日更新

This policy covers Crosync Drop for iPhone and Crosync Hub for Mac and Windows. The apps transfer selected files directly between devices on a local network. Your photos, videos, and file contents are not sent to our servers as part of a transfer.

Files and local records

Crosync Hub accesses folders you choose to share. Crosync Drop accesses media you select or authorize and may save received media to your photo library. The apps keep settings, shared-folder access information, transfer history, and temporary transfer files on your devices so transfers can resume. These records can remain until you clear them in the app or remove the app. If iCloud Photos or another system sync service is enabled, your device provider may sync media according to your settings.

Analytics and purchases

The iPhone app uses Firebase Analytics to record feature-use and subscription-flow events, such as a connection, transfer start or completion, file count, or purchase result. These events do not include transferred file contents or filenames. Firebase may process app-instance and device information under Google's Firebase privacy information. The Mac companion app does not include Firebase Analytics. In-app purchases in the iPhone app are handled by Apple through StoreKit under Apple's privacy policy.

Network and external links

File transfers use the local network. Analytics, purchases, and opening an external link, such as the App Store or these legal pages, may use the internet. We do not use the transferred files for advertising.

Changes and contact

We may update this page when the apps or data practices change. For privacy questions, contact lucktuite@outlook.com.
