Cookie Notice

Last updated November 2026

This notice explains what Lumen stores in your browser. The short version: the public website sets no cookies, and the signed-in app stores only what it needs to work.

1. The public website

The pages at lumen.symphia.ai set no cookies and use no analytics or advertising tools. Fonts and other files are served from our own domain, so visiting the site doesn't call a third party.

2. The signed-in app

If you sign in to Lumen, the app uses your browser's local storage, a technology similar to cookies, to hold:

  • your session, so you stay signed in;
  • the property you selected; and
  • small display preferences, such as whether a menu is open.

These are needed for the app to work. Lumen does not use them to track you across other sites.

3. Managing this

You can clear this data at any time in your browser's settings, which will sign you out.

4. Changes and contact

We will update this notice if this changes. Questions can be sent to support@symphia.ai.
