This Cookie Policy explains how QuantKey Solutions LLC (“QuantKey”, “we”, “us”) uses cookies and similar technologies on quantkey.com, related subdomains, and certain product interfaces we operate. It also explains how you can control them.

Note for customers: If you host pages, funnels, forms, or media on our platform, you control those properties and must implement your own compliant banner and cookie disclosures for your end users. We provide tools and guidance, but you are the controller for those sites.

1) What Are Cookies & Similar Technologies?

Cookies are small text files placed on your device; local storage, SDKs, pixels (beacons), and JavaScript tags are similar technologies used for measurement and integrations.

2) How We Use Them (Categories)

Strictly Necessary – Required for core site functionality, security, and account login.

Functional – Preferences, chat widgets, or feature toggles.

Analytics – Aggregate usage statistics to improve performance (e.g., page views, events).

Advertising/Retargeting – To measure or tailor ads on other sites/apps.

Communications – Email performance pixels, in‑product notifications, or A/B testing.

We avoid setting non‑essential cookies unless and until consent is captured where required by law (see Section 4).

3) Managing Your Preferences

Use the “Consent Preferences” control in the lower left on our pages to Accept All, Reject All, or Customize categories at any time. Your choices are stored (and can be withdrawn) with immediate effect.

4) Legal Bases & Regional Rules

EU/UK (PECR + GDPR): Setting non‑essential cookies (e.g., analytics/ads) generally requires prior, informed, opt‑in consent. Consent must be freely given (no pre‑ticked boxes or “cookie walls” that block content unless strictly necessary), specific, informed, and unambiguous, and it must be as easy to withdraw as to give. We structure our banner and controls accordingly.

U.S. State Requirements: Where our use of ad/retargeting pixels could be deemed a “sale”/“share” or “targeted advertising,” we provide a “Your Privacy Choices / Do Not Sell or Share” link and honor opt‑out preference signals such as Global Privacy Control (GPC) as required by California and recognized in Colorado.

Global Privacy Control (GPC): If your browser or extension sends a GPC signal, we treat it as an opt‑out of sale/sharing and targeted advertising for that browser/session, and endeavor to extend it where technically feasible.

Colorado UOOM: As of July 1, 2024, controllers subject to the Colorado Privacy Act must honor a recognized Universal Opt‑Out Mechanism; the Attorney General recognizes GPC (currently the primary mechanism on the public list).

5) What We Place and For How Long

Cookie lifespans vary (session vs. persistent). Our Consent Preferences center lists current cookies, purposes, and durations. We periodically update that inventory when vendors or configurations change.

6) Third‑Party Sites & Embedded Services

Our sites may include third‑party content (e.g., videos, maps, chat) that set their own cookies. Those providers’ policies govern their use.

7) Changes

We may update this Cookie Policy to reflect product or legal changes. We will post updates with a new “Last updated” date.
