PRIVATE MESSAGING, WITHOUT A PERMANENT PROFILE

Different conversations.
Different identities.

SEYVE does not ask you to become a profile. You simply create independent Spaces for the people, groups and moments that matter.

WHY SEYVE

One conversation should not follow you everywhere.

Most messengers

You create one identity, then use it for every conversation.

With SEYVE

You create a conversation, then choose the identity and rules that belong to it.

Not one central account with relationships attached to it. Independent relationships, brought together only on your device.

SEYVE SPACES

Every Space lives its own life.

A Space is more than a chat. It is an independent communication space with its own identity, keys and rules.

01

Your identity, here only.

Adrien with family. V-284 at work. Ghost-19 for a one-off contact. No global username needs to connect those Spaces.

02

Your retention rules.

Keep messages, erase them after a delay, after reading or when a session ends. Every Space can have its own lifecycle.

03

Your privacy level.

An everyday Space can stay simple. A sensitive conversation can use stronger network protections, up to Tor routing.

SEYVE PASS

Invite. Then let the invitation die.

A QR code or link can be valid for one person, a fixed number of uses, a limited time — or several of those rules at once.

  • 1 use for a private invitation.
  • 5 uses for a small group.
  • 2 hours for an event.
  • Manual approval for sensitive Spaces.

Once expired or consumed, the Pass no longer grants access to the Space.

HOW IT WORKS

Three actions. Everything else should disappear.

  1. 1

    Create a Space.

    No signup, no number to publish. SEYVE creates the cryptographic identity for that relationship locally.

  2. 2

    Share a Pass.

    QR code or temporary link. Your contact joins the Space without searching for you in a directory.

  3. 3

    Talk. SEYVE keeps contexts apart.

    Messages are end-to-end encrypted. History stays local; relays keep only what is needed for delivery.

LOCAL FIRST

Your history does not need to live with us.

SEYVE is designed to keep conversations on your devices. Servers temporarily transport already encrypted packets instead of building an archive of your life.

Synchronized deletion can remove a message from cooperating SEYVE clients. It never claims to erase a screenshot or a copy made outside SEYVE.

WHO IT IS FOR

For conversations that deserve a boundary.

Personal life

Family, friends, dating, temporary groups. Keep every context in its place.

Independent work

Clients, teams, associations and projects that do not need to become a social contact network.

Sensitive exchanges

Journalists, researchers, sources and conversations where identity, lifespan and metadata matter as much as content.

PRIVATE BY STRUCTURE

Trust should come from architecture, not a slogan.

No home-made cryptography.Public protocols and audited libraries.
No global identity for convenience.Spaces stay compartmentalized by design.
No premium privacy tier.Core privacy protections are not sold as an upgrade.
No impossible promises.SEYVE separates what it can guarantee from what a recipient can still copy.

SEYVE

You don’t have a SEYVE account.
You have Spaces.

Private messaging designed to let you communicate without building a permanent identity on a platform.
