Browsing this site
The pages, songs and setlists are plain files. We don’t ask you to log in and we set no tracking cookies. Your setlists, song versions and settings are kept in your own browser (local storage) and never leave your device unless you switch on Connect devices, below.
Some pages embed videos or music from YouTube, Spotify or SoundCloud, and playing one sends your request to that service under its own privacy policy.
Connect devices (optional)
Connect devices keeps your personal setlists and your own song versions the same on your phone, tablet and computer. It is off until you press Connect this device, press Join with a code, or confirm a pairing link you opened. Shared spaces (the Shared tab) are a separate opt-in that works the same way: you start or join one with a name of your choice, and the song versions and setlists you put there are visible, under that name, to everyone who has the space’s code. If your devices are connected, the shared spaces you are in (each space’s code, the name you gave it and your display name there) are kept the same on them too, encrypted like everything else, so a device you connect joins them as well; leaving a space on one device leaves it on the others. Until you do one of these the site sends nothing to the sync server.
- What is stored. Your data is encrypted in your browser with a key made from your sync code. The server stores only the encrypted data, a version number and an identifier derived from the code. We can’t read your setlists, and the code never reaches the server.
- Where. On a server of Cloudflare, Inc., which processes the data on our behalf.
- IP addresses. To keep abuse in check, the server counts how many sync copies are created from one address. For this it stores only a hash of your IP address, mixed with a daily changing salt, and deletes it after a day. Cloudflare itself may also see your IP address while handling the request, as any web host does.
- Cookies and accounts. None. Anyone who has your sync code can read and change your synced data, so keep it private.
- How long. A sync copy that hasn’t been updated for 18 months is deleted automatically.
- Deleting it. Press Delete server copy in the Connect devices dialog (for a shared space, in its Shared tab). Your data on your devices stays; Disconnect stops syncing on a device.
Your preferences (instrument, tempo, panels) are not synced.
Your rights
You can ask us for access to, correction or deletion of your data, and you can complain to the Dutch data protection authority (Autoriteit Persoonsgegevens). Because the synced data is encrypted and the code never reaches us, we can’t find or read your copy. Please don’t send us your sync code: it opens your data to anyone who reads it. Use Delete server copy, or let the copy expire after 18 months.
