Your identity, your device
No required email, phone number, global username, or uploaded address book.
Endryn is a local-first messenger built around device-owned identity, invitation-only connections, and less data in the middle.
Private prototype · iOS and Android planned

Your identity starts
on your device.
No account.
Your identity begins here.
No contact upload.
Connect by invitation.
No security theatre.
Clear about every boundary.
Most messengers begin with a central profile. Endryn begins with a key created on your device.
Share a short-lived invitation with someone you trust. Accept the connection. Keep the relationship at the edges.
Join early for free and help shape a calmer messenger built around people—not profiles, feeds, or data collection.
No required email, phone number, global username, or uploaded address book.
Connect intentionally with single-use QR codes and links that expire after fifteen minutes.
Choose when new messages should leave your device—from one minute to seven days.
Get prototype access, share direct feedback, and help set the priorities before public launch.
No trial timer. No payment card. Join the private prototype while Endryn works toward its public launch bar.
For the first people on the line.
Prototype access is limited and may be released in waves.
Privacy is not a promise in a headline. It is a series of choices about what a product never asks for, never keeps, and never pretends.
Endryn is an active prototype, not yet a production-secure messenger. Current limitations are stated inside the product because trust should be inspectable.
The direction is clear: less central custody, shorter-lived infrastructure, and an auditable security core before public launch.
Endryn is a local-first messaging prototype built around device-owned identity, invitation-only connections, and less centrally stored information.
Yes. Early access costs $0 and does not require a payment card. If paid plans arrive later, they will be explained clearly before anything changes.
No phone number, email address, account, or contact upload is required by the current prototype. Your Endryn identity is derived from keys created on your device.
Not yet. Endryn is an active prototype and is not presented as a production-secure messenger. The team is explicit about current limits while working toward an audited security core.
Endryn is being designed for iOS and Android. Early access availability may vary while the mobile builds are tested.
