Privacy

  • • No tracking of which articles you read.
  • • No personal data sent anywhere.
  • • One request to prismnews.io per unique article URL, cached for 6 hours.
  • • Source-available, MIT licensed. Inspect the code →
Does it work on Safari?
Not yet — Safari needs a separate WebKit-based build. Planned for v1.2.
What if my favorite site isn't supported?
Open an issue on GitHub with the domain — we add curated sources weekly.
Will Prism see what I read?
No. We only get the article URL when you actively open one on a supported site, and we don't log or associate it with you in any way.
Why does the widget sometimes not appear?
Because the story isn't in Prism's current cache yet, or its title doesn't fuzzy-match a clustered story. The cache refreshes every 25 min.
