What Quietport is

Quietport is free, open-source software (MIT licence) that keeps a shared folder in sync between the computers of people who were invited to it. The source is at github.com/ExecuteRelentless/quietport. Anyone can run their own hub; this page describes the hub run by the project at this address.

What the hub can and cannot see

• Files and file names are encrypted on your computer before they are uploaded. The hub stores ciphertext only and never holds the key that would open it. Nobody operating the hub can read your files or their names.
• The hub knows how much encrypted data each folder holds, so it can enforce the folder's size limit.

What the hub stores about you

• The name typed when you were invited or when you started a folder. No email address is required or collected by the software.
• For each computer: its name as reported by the operating system, operating system and version, the version of Quietport it runs, its private-network address, and a public key used to deliver folder keys to it.
• A check-in every 5 minutes with: last successful sync time per folder, amount of data waiting to sync, free disk space, connection type (direct or relayed), and error counts. Check-ins are kept for 7 days.
• An audit log of administrative actions (invites created, people added or removed, keys rotated), kept indefinitely.
• The network address that retrieved an invite or started a folder, used only for rate limiting and abuse prevention.

What it does not do

• No analytics, no advertising, no tracking pixels, no third-party scripts on this website other than fonts loaded from Google Fonts.
• No cookies are set by this website or by the software.
• Nothing is sold or shared with anyone.

Where data lives

The hub runs on a server in the United States. Encrypted backups of the hub's own database and of the encrypted folder contents are kept at a second location in the United States. Removing Quietport from a computer (Share a folder, then "Remove Quietport from this computer") deletes everything the software stored on that computer; the hub-side records for that computer are removed when its person is removed from their last folder.
