Cookie Policy

Last updated 18 October 2026 · Version 2026-10-04

LucianAlgo uses one cookie, to keep you signed in, and stores a few of your display choices in your browser. There are no advertising, analytics or tracking cookies, which is why the site doesn't show a cookie banner.

1. The cookie we set

NameWhat it doesHow long
sessionKeeps you signed in and protects your account from requests made by other websites. It is only sent over HTTPS and can't be read by scripts on the page.Until you sign out, or 12 hours at most

This cookie is strictly necessary: without it you can't sign in, so it doesn't need your consent.

2. Choices saved in your browser

The dashboard remembers some of your choices in your browser's own storage. They stay on your device, are never sent to us, and you can clear them in your browser settings at any time.

NameWhat it remembers
lucianAlgoThemeLight or dark theme
dashboard_account_filter, dashboard_group_filterThe account and routing group you filtered the dashboard by
lucianDashboardTimezoneThe time zone used for times in the dashboard
sidebar-collapsedWhether the side menu is collapsed
lucian_google_accountsGoogle accounts you signed in with on this device, so the sign-in page can suggest them
activeTab, lucian_trial_toast_shownThe dashboard tab you were on, and whether a trial reminder was already shown. Cleared when you close the tab.

To make pages load faster, your browser also keeps a copy of our public images and styles. These contain nothing about you or your accounts.

4. Changes

If we ever add cookies that aren't strictly necessary, such as analytics, we will ask for your consent first and update this page. Questions: lucianalgorithm@gmail.com.
