1. Your music library stays on your machine

Your existing music library is read in place on your machine and is never moved, copied out, or uploaded. Key, BPM and energy analysis runs locally on your own computer; the audio never leaves your machine to be analysed.

Cratefox does not log into, automate, or store your Spotify, Apple Music, or YouTube account. A link you paste is read only for the list of track names.

2. What we receive when you install

Setup asks cratefox.app once whether your access code is valid, sending a one-way hashed hardware id so your code locks to that computer. The raw hardware id never leaves your machine; we store only the hash.

That one-time code check is the only call the app makes to our servers: there is no telemetry from the app, and your downloading runs over your own connection, not through us.

3. The email you send for a code

There is no Cratefox account and nothing to log into. If you request an invite or ask to buy, you leave an email address; it is used to send your access code or payment details, and nothing else happens to your inbox. The only things on our side are that email and the install your code locks to. If you want your email removed after your code is issued, write hey@cratefox.app and it will be deleted.

4. Peer-to-peer sharing, disclosed

Cratefox pulls the tracks you are missing over a peer-to-peer connection it sets up on your machine, under an identity you choose (or an auto-generated one), so the connection is yours, not ours.

Because that connection is a peer-to-peer network, the tracks you download land in a folder that is shared back to the network, and this is on by default. Only your downloads and shared folders are shared, never your wider music library. You can turn sharing off at any time with the Sharing switch at the bottom of the app (or by removing those folders from the shares list in ~/cratefox/slskd/slskd.yml).

You are responsible for what you pull and share. None of that traffic passes through Cratefox servers.

5. This website

No third-party analytics, no cookies, no session replay, no ad trackers. The site keeps first-party daily totals only: aggregate counts of how many, never who. No user ids and no stored IP addresses (a salted hash that expires within an hour is used only to rate-limit abuse), and the counters themselves expire after 90 days. Open your Network tab and check.

6. Removal

Removing Cratefox is one line in Terminal on a Mac or PowerShell on Windows, and it deletes everything the installer put on your machine; your music library is never touched. The exact lines are at cratefox.app/help. Removing the app does not delete the hashed install record your code is locked to; that record is what keeps one code to one computer. If you want that record cleared, write hey@cratefox.app; clearing it frees your code to claim a fresh install.

7. Changes and contact

This page changes as Cratefox grows; the current version always lives here, and material changes will be noted. Questions? hey@cratefox.app.
