Privacy Policy
Showcast helps you discover musical acts from forwarded venue and ticketing emails. This policy describes what information we collect, how we use it, and who helps us process it.
What we collect
When you forward an email to Showcast, we receive and process:
- Your sender email address — stored with your Lineup so we can reply to you.
- The forwarded email content — read to extract artists, venues, and show dates. We do not keep the raw email body after processing; we store a SHA-256 hash of the inbound message for deduplication only.
- Derived artist and show data — names, venues, dates, and Spotify links assembled into your Lineup.
Why we use it
We use this information to:
- Send you a reply email with a link to your Lineup.
- Deduplicate repeat forwards of the same email so we do not process duplicates unnecessarily.
- Assemble and display your Lineup — artist cards, show dates, and listening links.
Third-party processors
Showcast relies on the following services to operate. Each may process data on our behalf under their own privacy terms:
- Postmark — inbound and outbound email delivery.
- Supabase — database hosting for Lineups and derived data.
- Anthropic — large-language-model processing (see below).
- Spotify — artist search, top-track links, and track-player embeds (third-party iframes on the Lineup).
- Vercel — application hosting.
- Sentry — error monitoring on our servers and in your browser when you view a Lineup.
- Axiom — operational logging.
- Langfuse — LLM observability.
- Impact — affiliate link wrapping for Ticketmaster ticket URLs (see below).
- Ticketmaster — ticket purchase destination.
- SeatGeek — ticket purchase destination.
Lineup visitors: ticket links and affiliate wrap
If you open a Lineup (whether or not you forwarded the email), the page may show ticket purchase links for upcoming shows. Ticketmaster URLs may be wrapped through Impact at render time so Showcast can earn a commission if you buy tickets through those links. SeatGeek links are pass-through today — we send you to SeatGeek directly.
When you click a wrapped Ticketmaster link, the affiliate network (Impact) may set an attribution cookie on its own domain and may see your IP address and browser details. Showcast does not set that cookie on Lineup load — it is only set when you click a wrapped link.
There is no cookie banner and no opt-out of wrap. If you prefer not to use wrapped links, you can navigate to Ticketmaster or SeatGeek directly.
Lineup visitors: Spotify embeds
The Lineup embeds Spotify track players as third-party iframes so you can preview songs without leaving the page. Spotify's own privacy terms apply to those players.
Automated processing with AI
To extract artists and venues from your forwarded email, we send the email content to Anthropic, a large-language-model provider. Anthropic processes the text to identify acts and show details; we do not use your email content to train models.
Retention
Lineups persist indefinitely and are not hard-deleted. If you would like a Lineup removed, contact us at info@showcast.events.
Public Lineup links
Each Lineup has a unique, unguessable URL. Anyone with the link can view the page — treat it like a shareable link. Do not forward your Lineup URL to people you do not want to see it.
