Overview

What does Keen-Slider do?

What Is Keen-Slider?

Keen-Slider is a lightweight, dependency-free JavaScript library for creating sliders, carousels, and touch-enabled interactive components. Weighing approximately 5.5kb gzipped, it delivers native-feeling touch and swipe interactions across all browsers and devices, including React Native. The library is framework-agnostic, working seamlessly with React, Vue, Angular, TypeScript, and vanilla JavaScript. Keen-Slider is open source under the MIT licence and maintained by rcbyr on GitHub.

Cookies and Data Collection

Keen-Slider does not set any cookies. It does not use localStorage, sessionStorage, or any other browser storage mechanism. The library operates entirely in memory during page rendering, handling touch events and CSS transforms without any persistent storage or data collection. No personal data is collected or processed by the library code.

GDPR and ePrivacy Implications

Since Keen-Slider does not set cookies or collect personal data, it falls outside the scope of the ePrivacy Directive consent requirement (Art. 5(3)). No lawful basis for data processing needs to be established for the library itself. When loaded from an external CDN such as jsdelivr, the browser sends the visitor's IP address to the CDN provider, which constitutes data processing under GDPR.

CDN Loading and International Data Transfers

When served from cdn.jsdelivr.net, the visitor's IP address is transmitted to Cloudflare or Fastly infrastructure operating globally including the United States. Cloudflare participates in the EU-US Data Privacy Framework. To eliminate any transfer concern entirely, install Keen-Slider via npm and bundle it locally in your build process.

Consent Requirements

No consent banner or cookie notice is required for Keen-Slider. The library qualifies as a strictly necessary technical component for website presentation. If loaded from a CDN, mention the CDN provider in your privacy policy but this does not trigger a consent requirement.

Practical Compliance Steps

For maximum GDPR compliance, self-host Keen-Slider by installing it via npm and bundling it with your application. This eliminates all third-party requests. If using a CDN, mention the CDN provider in your privacy policy. No cookie banner changes are needed and Keen-Slider should not appear in your cookie policy because it sets no cookies. The library is actively maintained, supporting modern frameworks and receiving regular updates.
