Chronological

Private spaces for your people.

Chat, share photos and plan get-togethers in private circles. See what happened, newest first, with no ranking.

Invite-only. Available on web, Windows and Android (beta).

Open Chronological Download for Windows

The Windows app installs for you alone, with no administrator needed, and keeps itself up to date. It isn't signed yet, so Windows may show a warning the first time. The iPhone app is in development. Request Android beta access below.

How it works

  • Nothing public

    No public profiles or public directory, and no posts anyone outside a circle can see. Find people by their exact email address, contacts or an invite. In the app, only a circle's members can open what's in it. It isn't end-to-end encrypted.

  • Invite only

    You join Chronological through an invite link from someone who's already in. Nobody can sign up on their own.

  • Contact matching uses hashes

    Your contacts are hashed on the device and never uploaded. Chronological compares the hashes, shows you who already has an account, and throws the rest away. On the web, you connect by invite link or email.

  • Connections go both ways

    One person asks and the other accepts. Either of you can remove the connection or block the other at any time.

  • Newest first. No algorithm.

    The feed is what happened in your circles, in the order it happened. Nothing is ranked.

In a circle

  • Chat: text, photos, uploaded videos, videos recorded in the app and voice notes.
  • Gallery: every photo and video sent in the circle, by date and type.
  • Activity: media added, posts and people joining.
  • Events: choosing Going on a get-together creates a circle for everyone going, with its own chat, gallery and activity.

Chronological privacy

Circles, messages and media are stored with Google Firebase in Sydney, Australia. They are not end-to-end encrypted. You can delete your account in the app or on the web.
