Cookie Policy

Last updated 17 October 2026

This policy explains the cookies and similar browser storage that Moso uses. Moso is run by [LEGAL ENTITY NAME] ("we"). For everything else about your data, see the Privacy Policy.

The short version

  • Moso only uses cookies it needs to work: keeping you signed in and remembering your last workspace.
  • There are no analytics, advertising or tracking cookies, and no third-party cookies.
  • Because every cookie is strictly necessary, we don't show a cookie banner.

What a cookie is

A cookie is a small text file a website stores in your browser. The site reads it back on your next visit. Similar technologies, such as your browser's local storage, work the same way, so we cover them here too.

Strictly necessary cookies

Moso can't sign you in or work properly without these.

sb-<project>-auth-token

Sometimes split into parts ending .0, .1 and so on.

Purpose
Keeps you signed in. It holds your sign-in session, which is refreshed while you use Moso.
How long
Up to 400 days, or until you log out.
Set by
Moso, through Supabase Auth

sb-<project>-auth-token-code-verifier

Purpose
A one-time security code that finishes a sign-in safely: signing in with Google, confirming your email or resetting your password.
How long
Removed once the sign-in completes.
Set by
Moso, through Supabase Auth

moso_workspace

Purpose
Remembers the workspace you last opened, so Moso opens there next time.
How long
1 year.
Set by
Moso

<project> stands for the ID of Moso's Supabase project. These cookies are first-party: they belong to the Moso website and are only sent to it.

Local storage and other browser storage

Moso also keeps a few settings in your browser's local storage. They stay on your device and are never sent to us:

  • Theme (moso-theme): light or dark mode.
  • Layout and display choices: for example which panels are open, which memory tabs you had open, which chat updates you've already seen and whether Claude's replies are shown.

If you install Moso to your Home Screen or turn on notifications, your browser also stores Moso's service worker. It lets Moso open like an app and receive push notifications. You can turn notifications off in Moso's settings or in your browser at any time.

Analytics and advertising

Moso doesn't use analytics, advertising or social media cookies, and doesn't load third-party tracking scripts. If we ever add any, we'll list them here first and, where the law requires it, ask for your consent before setting them.

One exception to know about: if you sign in with Google, your Google profile picture is loaded from Google's servers when Moso shows it. Moso sends Google no information about the page you're on, but Google's own privacy policy applies to that request.

How to clear or block cookies

You can delete Moso's cookies and local storage at any time in your browser's settings, usually under Privacy or Site data. Logging out removes the sign-in cookie. If you block these cookies, you won't be able to sign in to Moso.

Changes and contact
