Manage Your Cookie Preferences

You can change your cookie consent at any time. Essential cookies cannot be disabled as they are required for the Platform to function.

1. What Are Cookies?

Cookies are small text files that are placed on your device (computer, tablet, or smartphone) when you visit a website. They are widely used to make websites work efficiently, remember your preferences, and provide information to site owners.

Cookies are not programs and cannot carry viruses or malware. They can only be read by the website that set them (first-party cookies) or, in some cases, by third-party services used by that website.

We also use similar technologies such as localStorage (for client-side preference storage) and session storage (cleared when you close your browser).

2. How We Use Cookies

Quantic Aether uses cookies to:

•Keep you logged in during your session and across return visits
•Protect your account against unauthorized access and CSRF attacks
•Remember your preferences such as language selection
•Process payments securely through our payment provider (Stripe)
•Understand how the Platform is used so we can improve features and content (analytics, with consent only)
•Attribute your visit to the correct marketing source, if applicable

We do not use cookies to build advertising profiles, track you across unrelated websites, or sell your browsing data.

4. Third-Party Cookies

Some cookies are set by third-party services we use:

Stripe (payment processing) Stripe sets cookies to prevent fraud during the payment process. These are considered essential for the payment flow. Stripe's privacy policy: https://stripe.com/privacy

369-Atlas Advanced System (AI features) The AI features are powered by the 369-Atlas Advanced System. No cookies are set in your browser for AI functionality; all AI processing is server-side only.

We do not embed third-party social media pixels, advertising networks, or tracking pixels from Google Ads, Meta, or similar platforms.

5. How to Manage Your Cookie Preferences

Cookie Preference Center When you first visit the Platform, you will see a cookie consent banner that allows you to accept or decline non-essential cookies. You can change your preferences at any time by clicking "Cookie Settings" in the page footer.

Browser Settings Most browsers allow you to: - View and delete cookies stored on your device - Block all cookies (note: this will prevent login and other essential functions) - Block third-party cookies specifically - Receive a warning before a cookie is stored

How to manage cookies in popular browsers: - Chrome: Settings → Privacy and Security → Cookies - Firefox: Settings → Privacy & Security → Cookies and Site Data - Safari: Preferences → Privacy → Manage Website Data - Edge: Settings → Privacy, search, and services → Cookies

Do Not Track (DNT) Some browsers send a "Do Not Track" signal. We honor this signal by not activating non-essential cookies when DNT is detected.

Note that blocking essential cookies will prevent you from logging in and using core Platform features.

6. Cookie Retention Periods

Cookies are either session cookies (deleted when you close your browser) or persistent cookies (stored for a defined period). Specific durations for each cookie are listed in the table above.

We periodically review cookies in use and remove any that are no longer necessary. Our longest-lasting persistent cookie expires after 24 months.

7. Legal Basis

Under the EU ePrivacy Directive (implemented in Spain via LSSI-CE) and GDPR:

•Essential/Technical cookies do not require consent as they are strictly necessary for a service explicitly requested by the user (Art. 5(3) ePrivacy Directive exemption).
•Analytical and Marketing cookies require your prior, informed, and freely given consent before being set. You can withdraw this consent at any time via the Cookie Preference Center.

Our cookie consent mechanism records your choice with a timestamp. This record is stored for audit purposes.
