Privacy Policy

Effective October 11, 2026

Transfer Deck is a Mac app for browsing and transferring files in Amazon S3, S3-compatible storage, and SFTP, WebDAV, FTP and FTPS servers. It was built to collect nothing about you.

What we collect

Nothing. Transfer Deck has no user accounts, analytics, advertising, crash reporting or tracking of any kind, and its developer receives no data from the app.

Your keys and passwords

The credentials you enter (S3 Access Key IDs, Secret Access Keys and session tokens; server user names and passwords; SSH private keys and their passphrases) are stored only on your Mac, in the macOS Keychain. They are used only to connect to the server you configured and are never sent anywhere else. For S3, your secret key itself is never transmitted, only the signatures made with it. Removing an account in the app deletes its credentials.

For SFTP servers, the app remembers each server's public host key fingerprint on your Mac, to warn you if the server's identity ever changes.

Your files

Files move directly between your Mac and the storage service or server you connect to. They don't pass through any server of ours. Web links you create for S3 files are signed with your own keys and expire at the time you choose.

Purchases

The free trial and the unlock are in-app purchases handled entirely by Apple. We don't receive your name, email, or payment details. Apple's handling of purchases is described in Apple's Privacy Policy.

Third parties

When you connect to a storage service or server, your use of it is governed by that provider's own terms and privacy policy, for example AWS's Privacy Notice.

This website

This website uses no cookies, analytics or trackers. Like any website, the hosting provider may keep standard technical logs (such as IP addresses) for security and reliability.

Children

The app collects no personal information from anyone, including children.

Changes

If this policy changes, the new version will be posted on this page with a new effective date.
