Cookie Policy
Version 1.1 — Last Updated: 03 March 2026
1. Introduction
This Cookie Policy explains how QuantML ("QuantML", "we", "us", or "our") uses cookies and similar technologies when you access www.quantml.ai and the QuantML platform (the "Services").
This Policy should be read together with our Privacy Policy.
2. What Are Cookies?
Cookies are small text files stored on your device when you visit a website. They help websites function properly, improve user experience, and provide analytical insights.
Cookies may be:
- Session cookies — deleted when you close your browser
- Persistent cookies — stored for a defined period
3. Categories of Cookies We Use
3.1 Strictly Necessary Cookies
These cookies are essential for core platform functionality, including:
- User authentication
- Secure login sessions
- Fraud prevention
- Security controls
These cookies cannot be disabled as the Services cannot function properly without them.
Legal basis: Legitimate interests (Article 6(1)(f) GDPR)
3.2 Functional Cookies
These cookies enhance your experience by remembering your preferences, such as:
- User interface preferences
- Dashboard layout settings
- Language or display preferences
Legal basis: Consent
3.3 Analytics Cookies
These cookies help us understand how users interact with the platform. Data collected includes:
- Pages visited and time spent
- Features used
- Error events and performance metrics
Analytics data is aggregated and anonymised where possible.
We use PostHog as our analytics provider. PostHog is initialised and may set analytics cookies/local storage only after you have granted analytics consent through our cookie management tools. Before consent, PostHog does not load, capture, or store anything. On consent, we capture pageviews and selected product events (e.g. sign-up and signal-view actions) for the sole purpose of understanding and improving the platform. You can withdraw consent at any time, which opts you out of capture and clears PostHog's stored identifiers.
Legal basis: Consent
4. Third-Party Cookies
Some third-party services integrated into the platform may set their own cookies. These include:
- Stripe — for payment processing and fraud prevention
- PostHog — for consent-gated product analytics (pageviews and selected product events), loaded only after analytics consent
We do not control third-party cookies. Please refer to the relevant third-party privacy policies for more information.
5. Managing Cookies
You can control and manage cookies in the following ways:
- Through your browser settings — most browsers allow you to refuse or delete cookies
- Via our cookie consent banner (where applicable) — you can withdraw consent at any time
Please note: disabling strictly necessary cookies will impair the functionality of the Services and you may not be able to log in or access key features.
6. Changes to This Policy
We may update this Cookie Policy from time to time. Updates will be posted on this page with a revised "Last Updated" date. Continued use of the Services after changes constitutes acceptance.
