The map and the TV apps
The live map at map.dzco.tech and the DZCO Live apps for LG, Apple TV, Google TV and Fire TV show public information about live shows. They don't ask you to sign in, don't show ads, and don't use third-party analytics, advertising identifiers or tracking cookies.
- We count visits to our websites ourselves, to know how many people use them. For each day we keep a scrambled form of your IP address (we can't turn it back into the address), the country Cloudflare estimates from it, the name of the website that linked you here (never the full link), and which steps you took, such as opening a show, following a ticket link or starting an order (never what you typed). These counts are deleted after 90 days and never shared or sold.
- To draw the map, your device downloads the current show data from our servers (hosted by Cloudflare). Like any web server, Cloudflare briefly processes your IP address to deliver it; we don't use it to identify you.
- To center the map on your part of the world, the page asks our server for Cloudflare's rough estimate of where your connection comes from, rounded to about 60 miles (or uses your device's time zone). It isn't stored or logged.
- If you press the map's location button, your browser asks whether to share your device's location. If you allow it, the page uses it on your device only, to move the map there; it is never sent to us. If you don't, the page uses the rough estimate above instead.
- The TV apps remember one setting on your device: whether sound is on or off. It never leaves the device.
- The website remembers, in your browser only, whether sound is on and the artists you've typed into "Map my shows", so their shows get a cheer. Neither is sent to us; clearing your browser's site data forgets them.
- When you tap a show on the website, it can show links to other sites: tickets, the setlist on setlist.fm, and the artist on Spotify and YouTube. To find a show's tickets, our server asks Ticketmaster for that show (artist, venue location and date only, nothing about you). Those sites have their own privacy policies once you follow a link.
Your favorite artists
- Artists you search for, star on a show card, or (if you connect Spotify or YouTube) your top artists there are your favorites: their shows get a gold ring and a label, a count under the title, and a note when they go on stage. Only the artists' names are kept, in your own browser. Nothing about it is sent to our servers.
- Names that came from Spotify or YouTube are refreshed each time you open your music, and removed when you disconnect that service or after 30 days without a refresh. Unstar a show card to drop an artist you added.
- If you allow notifications ("Tell me when I'm away"), your browser shows one when a favorite goes on stage while the page is in the background. You can turn that off in your browser's site settings.
Music (Spotify)
- During the disco you can connect your Spotify account. Spotify asks you to log in and approve; you then see a wall of album covers from your top tracks (all-time and lately) and saved albums, and from acts playing near the map's view tonight. With Spotify Premium, a cover plays in the page.
- Your Spotify access stays in your own browser (its local storage). We don't send it to our servers and we don't store your listening, library or account details anywhere. The page asks Spotify directly, only while it's open.
- "Disconnect Spotify" removes that access from your browser. You can also remove DZCO from your Spotify account's apps page at any time.
- Spotify has its own privacy policy for what it sees when you log in or play music.
Music (YouTube)
- You can also connect YouTube. Google asks you to sign in and allow DZCO to see your YouTube account (read only). The wall then shows your liked videos, and videos play in YouTube's own player on the page. DZCO uses YouTube API Services: by connecting YouTube you agree to the YouTube Terms of Service, and Google's Privacy Policy applies to what Google sees.
- The access Google gives us stays in your own browser for at most an hour (its session storage) and is only used, while the page is open, to show your liked videos and to search YouTube for you. We don't send it or anything from your YouTube account to our servers, and we don't share it with anyone.
- The only thing kept after the page closes: the names of channels you've liked two or more music videos from, in your own browser, as favorite artists (see above). They're refreshed each time you open YouTube on the wall and deleted when you disconnect, or after 30 days without a refresh.
- "Disconnect YouTube" removes it and tells Google to cancel it. You can also remove DZCO at any time on your Google account's third-party connections page.
- DZCO's use of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.
City flights (local.dzco.tech)
- local.dzco.tech plays a looping flight over today's shows. The video is made on your device or, for the cities at local.dzco.tech/sanfrancisco, /berlin and /losangeles, on our servers, and is kept on your device so it doesn't download again until the next day's flight. It never leaves your device.
- On those city pages, a small player shows live videos of the acts as the flight passes their venues. The
videos are official live performances from each act's own YouTube channel, played in YouTube's embedded player.
While a video plays, your device connects to YouTube (Google), which receives your IP address and browser details
and may set cookies under Google's Privacy Policy. YouTube's
Terms of Service apply to the videos. Add
?clips=0to the address to turn the videos off. - To choose the videos, our servers use the YouTube API Services: they read public information about each act's channel and videos (titles, length, whether a video may be embedded). Nothing about you is sent. We keep that information for at most 30 days.
"Add your venue"
If you use the Add your venue form, we receive what you type (your email address and details about your venue) and the country your connection comes from. We keep it in our mailing service, Mailchimp, to review your venue and reply to you. If you tick the news box, we also send occasional news; every email has an unsubscribe link. We don't sell or share this information.
Your own map (map.dzco.tech/me)
- When you paste notes about shows or travel plans, the text is sent to Anthropic's Claude model to pick out the artists, places and dates, and the result to our lookup service (on Amazon Web Services) to find each show in Chartmetric's listings. We don't keep the text you pasted. Anthropic processes it under its commercial API terms; by default it does not use API data to train its models.
- Shows we can't find in the listings are checked on the web by Claude (up to 10 per map). When the web confirms one, we add the show itself (artist, date, venue, the source page, nothing about you) to a list we share with our listings partner, Chartmetric, so their listings improve.
- If you save a map, we keep the shows on it (dates, artists, venues) under a private, unguessable link, plus a code in your browser that lets you edit it. Anyone with the link can see the map.
- If you ask us to email the link, your email address goes to Mailchimp (as for "Add your venue"); we keep only a scrambled (hashed) copy with the map. Tick the news box only if you also want news.
- To limit abuse we count requests per connection per day, using a scrambled form of your IP address that we can't turn back into the address.
- To delete a saved map, email info@dzco.tech with its link.
Orders
- Payments are handled by Stripe; we never see your card number. Stripe gives us your name, email, and the shipping address for tees and mugs.
- Tees and mugs are printed and shipped by Printful, postcards by Lob. Each receives the print image and the delivery address it needs, and nothing else. For a postcard you send to a friend, that's their name and address and your message.
- We keep order records (what was ordered, status, the print image) for our accounts and to help with problems.
