Cookie Policy

Last updated: 21 April 2026

This Cookie Policy explains how Quantarell uses cookies and similar technologies. We believe in transparency and want you to understand exactly what data is stored on your device.

What Are Cookies?

Cookies are small text files stored on your device when you visit a website. They help the website remember your preferences and improve your experience.

Cookies We Use

We use only essential cookies that are necessary for the platform to function. We do not use advertising, marketing, or third-party tracking cookies.

Essential Cookies

Session Cookie: Maintains your authenticated session so you don't have to sign in on every page. This cookie is deleted when you close your browser or sign out.

Security Cookie: Helps prevent cross-site request forgery (CSRF) attacks and protects your account.

These cookies are strictly necessary and cannot be disabled without breaking core platform functionality.

Third-Party Cookies

Google OAuth: during sign-in, Google may set cookies for authentication, governed by Google's privacy policy.

Stripe (Premium billing only): if you subscribe to Quantarell Premium, Stripe may set cookies on its own checkout page for fraud detection, governed by Stripe's cookie policy.

We do not use Google Analytics, Facebook Pixel, or any advertising/tracking services.

Managing Cookies

You can control cookies through your browser settings. Most browsers allow you to block or delete cookies. However, blocking essential cookies will prevent you from using authenticated features of Quantarell.

Since we only use essential cookies, there is no cookie consent banner - these cookies are required for the platform to work.

Changes to This Policy

We may update this cookie policy if we change how we use cookies. Any changes will be posted on this page with an updated date.
