News sources
headlines that link out.
The news tab shows headlines from RSS feeds you choose. The app links to the publisher; no article body is copied.
01How news works
- The backend reads the feeds (
firebase/functions/src/api/news.ts). It understands RSS 2.0, RSS 1.0 and Atom. - Only the headline, the link, the date, a plain-text summary of at most 280 characters and the feed's image URL are kept. Tapping a headline opens the publisher's page. No article bodies are copied.
- Headlines are tagged with coins: a top-250 coin is tagged when its name, or its symbol (as a whole word, 3 or more capital letters), appears in the title or summary. The coin screen shows the news tagged with that coin.
- The scheduled job
refreshNewsruns every 15 minutes. Headlines are kept for 7 days by default; older ones are deleted.

Publishers' terms apply
These feeds are public, but each publisher sets its own terms for using its feed, headlines and images, especially in a commercial app. Check them, and remove any feed you are not allowed to use. The publishers' names and content belong to them.
