Privacy
Sur is built to work without knowing who you are. There are no accounts, no advertising and no tracking cookies. This page explains the little that is stored and how to remove it.
What we store
When you first like a song, make a playlist or listen to a song for about thirty seconds, Sur creates an anonymous listener record and saves its random identifier in a cookie called sur_listener. The cookie is only readable by Sur’s server and lasts one year.
Your likes, playlists and listening history are stored in the site’s database next to that identifier. We never ask for your name, email address, phone number or password.
Files from your device
Songs you open from your own device are played inside your browser tab. They are never uploaded, and their titles and artwork are read on your device. The list is forgotten when you close or reload the tab, and these songs are never added to your history.
Settings kept in your browser
Your volume, shuffle and repeat choices, and the songs from the library that were in your queue, are kept in your browser’s local storage so the player can pick up where you left off. They never leave your device.
Where the music streams from
Library songs are streamed from Wikimedia Commons. Like any website your browser loads files from, its servers receive your IP address and basic browser details with each request, as described in the Wikimedia Foundation privacy policy.
Visit statistics
The published site counts visits with privacy friendly analytics that use no cookies and do not identify you. They show totals such as page views and countries, never individual listening habits.
Deleting your data
Open History and choose Delete all my data. Your listener record, likes, playlists and history are removed straight away and the cookie is cleared. Clearing your browser's cookies also disconnects you from that data.
Data is kept until you delete it.
