Keryx

One reader. Every device. Keryx is a local-first, cross-platform 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 phone and your desktop. FEATURES • Multi-device sync via your own cloud storage (Dropbox or OneDrive) — no account with Keryx itself, ever. (Google Drive sync, available in the Google Play and GitHub builds, is not part of the F-Droid build because it needs Google Play services.) • 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 • 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. The F-Droid build contains no Google Play services and never checks for updates itself — F-Droid does that. 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 or OneDrive for sync. Nothing else.
