## What is Keryx?

One reader. Every device.

Keryx is a local-first RSS reader. By default, all of your data lives on your device; turn on cloud sync only if you want the same subscriptions, read/starred status, and articles to follow you between your devices.

FEATURES

• Sync through your own cloud storage (Dropbox, Microsoft OneDrive, or Google Drive) — no account with Keryx itself, ever
• Local-first: works fully offline, with no sync required
• Fast local full-text search across article titles and content
• Organize feeds with tags (cross-cutting labels) and folders (hierarchical grouping)
• RSS 2.0 and Atom 1.0 support (RSS 1.0/RDF is also loosely parsed)
• OPML import and export, for moving to or from other RSS readers and for backing up your subscriptions
• Background refresh and new-article notifications, entirely on your device
• Completely free — no freemium tiers, no trial period, no ads
• Open source — the full source code is public and can be inspected or modified by anyone

PRIVACY

Keryx has no user accounts and no server operated by its developer. There is nothing to sign up for, and nothing that its developer's own infrastructure ever receives. The app includes no analytics, telemetry, crash reporting, advertising, or tracking of any kind.

Keryx talks only to servers directly relevant to what you're doing: the feeds you subscribe to (and their favicons) and — only if you connect one — Dropbox, OneDrive, or Google Drive for sync. The one exception is an article's own content: the images, videos and embeds it references are loaded from their original hosts when you open it. Nothing else.

Dropbox, OneDrive, and Google Drive are trademarks of their respective owners; Keryx is not affiliated with or endorsed by them. Google Drive is a trademark of Google Inc. Use of this trademark is subject to Google Permissions.
