What this policy covers
Quantellect Technologies Inc. uses this policy to explain cookies and similar technologies on quantellect.ai. These technologies can include browser storage, local storage, pixels, software identifiers, embedded content, and network requests that transmit information about your device or activity.
Some technologies are necessary to provide a service you request. Others are optional. A cookie's name, the fact that a technology is operated by Quantellect, or the absence of advertising does not by itself determine whether consent is required.
Categories
Strictly necessary. These support functions such as maintaining an authenticated session, preventing abuse, routing a request, and recovering from a failed page load. They are limited to what is needed for the relevant function.
Preferences. These remember choices you make, such as your selected geography, theme, chart layout, calendar filters, saved screener settings, and device-local watchlists. They are stored in your browser and are not sent to an advertising provider; watchlist changes are also captured server-side as described under Analytics.
Analytics. The website uses Cloudflare Web Analytics, a measurement script delivered by Cloudflare at the network edge that records page views and performance metrics. On our measured visits it set no analytics cookie and no browser storage. Quantellect also records watchlist activity server-side as described below.
External content and communications measurement. The public website does not embed external video, social widgets, or third-party chart iframes. Calendar reminder emails do not include open or click tracking pixels added by Quantellect.
Advertising technologies. The current website does not display advertising. Quantellect's first-party advertising system is switched off in production and records nothing. If advertising is introduced, this inventory will be updated before its use where required.
Current technology inventory
Everything listed is first-party unless noted. "Persistent" means the browser keeps the entry until you clear it.

Sentry (@sentry/nextjs on the website; @sentry/node on the backend) |

| Watchlist activity capture (server-side) | When you change a watchlist, the event and current membership are sent to Quantellect's ClickHouse environment with a pseudonymous owner identifier and, if signed in, your account identifier. Event history is kept for two years; current membership has no code-defined expiry. Disabled when your browser sends Do Not Track. | Analytics | Server-side, not browser storage |
No IndexedDB use was found in the website's code. No advertising-network cookie appeared on our measured visits.
Your controls
You can clear Quantellect cookies and local storage through your browser; this may sign you out and reset saved preferences or device-local watchlists. Browser Do Not Track disables Quantellect's server-side watchlist activity capture when recognized, but does not delete previously recorded events or membership. Cloudflare Web Analytics uses no cookies or local storage and is not controlled through a Quantellect cookie setting.
The website does not currently offer a cookie settings control or a consent banner, because no technology listed above is switched on or off by such a control. If we add an optional technology that requires consent, we will add the control before that technology runs. Closing a notice, scrolling, continued browsing, accepting the Terms, or signing up for an account does not count as consent to optional tracking.
Your browser may also allow you to inspect and delete stored data or block cookies. Blocking strictly necessary storage can affect functions such as signing in. Choices are specific to the browser or device.
The website does not currently implement Global Privacy Control handling. Where applicable law requires an opt-out preference signal to be honored, we will apply it to the covered processing.
