Cookie Policy
Effective Date: August 18, 2026 · Last Updated: August 18, 2026
This Cookie Policy explains how the Quantrolix marketing website (apps.quantrolix.ai) stores information in your browser. It supplements our Privacy Policy.
localStorage and sessionStorage to keep
you signed in and remember a trial in progress, and no third-party analytics or
advertising script is loaded by default.
What We Store
We do not use HTTP cookies for tracking or advertising. Instead, this site stores a small amount of data directly in your browser using the Web Storage APIs:
| Storage Key | Type | Purpose |
|---|---|---|
quantrolix_access_token / quantrolix_refresh_token | localStorage | Keeps you signed in to the Auth Gateway between visits |
quantrolix_user | localStorage | Caches your account profile so the site can render your signed-in state |
quantrolix_trial | localStorage | Tracks a free trial or free-plan signup in progress |
quantrolix_analytics | localStorage | A local, on-device log of page views and clicks (see below) |
qx_session_id | sessionStorage | A random identifier used to group events from the current browser tab; cleared when the tab closes |
None of this data is a browser cookie, and none of it is shared with advertising networks. It exists only so the site can function — staying signed in, remembering an in-progress signup, and rendering the right screen.
First-Party Analytics
Page views and interactions (like clicking "Start Free Trial") are logged to
localStorage on your own device so we can debug and understand usage.
This site does not load Google Analytics, Meta Pixel, or any other third-party
analytics or advertising script. An optional server endpoint exists in the code to
forward these events, but it ships unconfigured — no events leave your browser
unless that endpoint has been explicitly turned on for your session.
Third-Party Content
This page loads web fonts from Google Fonts (fonts.googleapis.com, fonts.gstatic.com). Loading a font may cause your browser to make a network request to Google's servers; Google's own cookie and privacy practices govern that request. We do not embed any other third-party widgets, trackers, or advertising content on this site.
Managing Your Storage
You can clear localStorage and sessionStorage at any time from your browser's settings (usually under "Clear browsing data" or "Site settings"). Clearing this data will sign you out and reset any in-progress trial signup, but will not delete your Quantrolix account — request account deletion per our Privacy Policy.
Changes to This Policy
We may update this Cookie Policy as the site's storage usage changes. Material changes will be reflected in the "Last Updated" date above.
