Moofx is a CSS3-enabled JavaScript animation library created by Valerio Proietti (kamicane). It provides smooth element animations using CSS3 transitions with a requestAnimationFrame fallback. The library is open source under the MIT licence and was archived in 2019. Moofx does not set any cookies, does not collect personal data, and does not perform any tracking or analytics. When loaded from a CDN, visitors' IP addresses may be transmitted to CDN providers. Self-hosting eliminates any privacy concern.
Moofx is a lightweight, CSS3-enabled JavaScript animation library created by Valerio Proietti. It leverages CSS3 transitions when available and falls back to requestAnimationFrame for smooth animations across all browsers. The library supports colour animations (rgb, rgba, hsl, hex), length unit conversions, and custom easing via cubic-bezier curves. Moofx is open source under the MIT licence, available via npm, and can also run in Node.js environments. The project was archived on GitHub in December 2019 but remains widely deployed on existing websites.
Moofx does not set any cookies. It does not use localStorage, sessionStorage, or any browser storage mechanism. The library operates entirely in memory during page rendering, animating CSS properties without any persistent storage or data collection. No personal data such as IP addresses, device identifiers, or behavioural information is collected or processed by Moofx code.
Since Moofx does not set cookies or collect personal data, it falls outside the scope of the ePrivacy Directive consent requirement (Art. 5(3)). Under GDPR, no lawful basis for data processing needs to be established for the library itself. However, when loaded from an external CDN such as jsdelivr, the browser sends a network request that includes the visitor''s IP address to the CDN provider, which may involve data processing under GDPR.

When served from cdn.jsdelivr.net, the visitor''s IP address is transmitted to Cloudflare or Fastly infrastructure operating globally, including in the United States. Under GDPR Chapter V, this constitutes an international data transfer. Cloudflare participates in the EU-US Data Privacy Framework, providing an adequacy basis. To eliminate any transfer concern, self-host Moofx by installing it via npm and bundling the file into your build process.
No consent banner or cookie notice is required for Moofx. The library qualifies as a strictly necessary technical component for website presentation. European data protection authorities have consistently held that front-end UI libraries without cookies or data collection do not require user consent. If you load Moofx from an external CDN, mention the CDN provider in your privacy policy but this does not trigger a consent requirement.
For maximum GDPR compliance, self-host Moofx by bundling it locally. This eliminates all third-party requests. If using a CDN, mention the CDN provider in your privacy policy. No cookie banner changes are needed. Since Moofx is archived and no longer maintained, consider migrating to actively maintained alternatives such as GSAP, Motion (Framer Motion), or anime.js for long-term security and compatibility.
Websites using Moofx must obtain user consent under GDPR regulations.
DPIA considerations
A DPIA is not required for Moofx. The library is a purely client-side animation component that does not process personal data, set cookies, or perform tracking.
Sample consent text

Third-party domains contacted
cdn.jsdelivr.netThis service may collect user data. Ensure GDPR compliance with FlowConsent.
No. Moofx does not set any cookies or use any browser storage. It is a purely client-side CSS3 animation library that operates entirely in memory.
No consent is required. Moofx does not set cookies or collect personal data. It qualifies as a strictly necessary UI component exempt from ePrivacy consent requirements.
Legitimate interest (Art. 6(1)(f) GDPR) applies for loading a front-end animation library. Since no personal data is processed by Moofx itself, no specific lawful basis is required.
Not directly. Moofx itself transmits no data. If loaded from a CDN like jsdelivr, the visitor's IP address is sent to CDN infrastructure which may include US servers. Self-hosting eliminates this transfer.
No. Moofx does not process personal data, perform profiling, or engage in systematic monitoring. No DPIA is needed.
Install Moofx via npm and bundle it locally to eliminate third-party CDN requests. If using a CDN, mention the provider in your privacy policy. No cookie banner changes are needed.
Yes. Since Moofx was archived in 2019, consider GSAP, Motion (formerly Framer Motion), anime.js, or the native Web Animations API. All offer similar CSS animation capabilities with active maintenance and security updates.
No. Since Moofx does not set any cookies, it should not be listed in your cookie policy. If loaded via CDN, mention the CDN provider in your general privacy policy.
