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 centre 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 100 km (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.
• 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.

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=0 to 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.
