Focused inboxes, strong search, useful bulk actions, reliable attachments, and a reader that protects your privacy by default.
A better home for your communication
One app. Your server. No one in the middle.
Keryx brings mail, calendars, contacts, and tasks into one thoughtful Android app. It connects directly to the services you choose, without advertising, analytics, or an intermediary Keryx cloud.
Android pre-release
Contact Eight Point Labs
Built as one system
Four tools that know about each other.
Calendar
Events, attendees, reminders, attachments, and practical day-to-day planning without leaving the app.
Contacts
Server address books remain the source of truth, with an optional bridge to Android Contacts when you want it.
Tasks
JMAP and DAV tasks alongside the messages and events they belong with, rather than hidden in another silo.
JMAP first
A modern protocol, with standards-ready fallback.
Keryx is designed around JMAP, where mail, contacts, calendars, and tasks can live on one server. It also supports IMAP and SMTP for mail, plus CalDAV and CardDAV for existing providers and self-hosted systems.
Private by architecture
Your data does not need another cloud.
Keryx connects your phone directly to your configured server. Remote images are blocked by default, credentials are protected with Android Keystore-backed encryption, and there are no advertising or analytics SDKs.
