The WingDrive app has no telemetry and no account. Indexing, thumbnails and search run on your device. Data travels only between devices you pair, end-to-end encrypted, or to cloud services you connect yourself.
This website has no cookies, no analytics and no third-party trackers. The download page asks the public GitHub API for the latest release from your browser, which GitHub may log like any request.
