    Overview

    slideck is a browser-based markdown presentation viewer. We are committed to protecting your privacy. This policy explains what data is collected, how it is used, and what rights you have.

    No User Accounts or Personal Data

    slideck does not require you to create an account. We do not collect your name, email address, or any other personal information directly.

    Local Data Storage

    Your presentation data (uploaded markdown files and related assets) is stored locally in your browser using localStorage and IndexedDB. This data never leaves your device and is never transmitted to any server.

    Analytics & Performance Monitoring

    We use Vercel Analytics and Vercel Speed Insights to understand how the app is used and to monitor performance. These services collect:

    • Page views and routes visited
    • Referrer information
    • Device type, browser, and operating system
    • Approximate country
    • Web Vitals metrics (FCP, LCP, CLS, etc.)

    No cookies are used. Visitors are identified by a daily-rotating hash that is discarded after 24 hours. There is no cross-site tracking, and no IP addresses are stored.

    Third-Party Data Processor

    Analytics data is processed by Vercel Inc. as a third-party data processor. You can learn more about their practices in the Vercel Analytics Privacy Policy.

    You have the right to:

    • Opt out of analytics — you can at any time(currently: declined)
