Privacy Policy

Last updated: February 28, 2026

FeatureDrop is an open-source library published by GLINR STUDIOS ("we", "us", "our"). This policy covers the FeatureDrop npm package, documentation site (featuredrop.dev), and Claude Code plugin.

The Short Version

FeatureDrop is a client-side library. We do not collect, store, or transmit any user data. Your data stays in your application. Period.

1. The FeatureDrop Library (npm package)

The featuredrop npm package runs entirely in your users' browsers or your server environment.

  • No telemetry. The library does not phone home, ping our servers, or send analytics.
  • No tracking pixels. No external scripts, images, or iframes are loaded.
  • No cookies. The library does not set cookies.
  • Local storage only. Feature dismiss states are stored in your users' localStorage or your chosen storage adapter (PostgreSQL, Redis, etc.) — all under your control.
  • Zero external network requests. Unless you explicitly configure a RemoteAdapter pointing to your own server.

Data the library stores locally

featuredrop:dismissedIDs of dismissed featuresYour chosen StorageAdapter
featuredrop:quiet-modeUser's Do Not Disturb preferencelocalStorage

This data is never sent to GLINR STUDIOS or any third party.

2. The Documentation Site (featuredrop.dev)

When you visit featuredrop.dev, we collect minimal analytics to understand how developers use our docs:

  • Plausible Analytics — privacy-focused, cookieless, GDPR-compliant page view tracking. No personal data is collected. Plausible privacy policy (opens in a new tab)
  • No cookies are set by our documentation site.
  • No personal information (name, email, IP address) is collected or stored.

What we track on the docs site

  • Page views (which pages are visited)
  • Referrer (where you came from)
  • Country (derived from IP, not stored)
  • Device type (desktop/mobile/tablet)
  • Outbound link clicks (to GitHub, npm, etc.)

What we do NOT track

  • Your identity
  • Your IP address (not stored)
  • Your browsing history
  • Cookies or local storage

3. The Claude Code Plugin

The FeatureDrop Claude Code plugin is a skill file that teaches AI assistants about the FeatureDrop API. It:

  • Runs locally in your Claude Code or Cursor IDE
  • Does not make network requests
  • Does not collect or transmit any data
  • Contains only documentation text (API reference, examples, best practices)

4. npm Package Downloads

When you install featuredrop via npm, the npm registry logs the download. This is standard npm behavior and is governed by npm's privacy policy (opens in a new tab), not ours.

5. GitHub

Our source code is hosted on GitHub. Interactions with our GitHub repository (starring, forking, issues, pull requests) are governed by GitHub's privacy policy (opens in a new tab).

6. Children's Privacy

FeatureDrop is a developer tool. We do not knowingly collect information from children under 13.

7. Changes to This Policy

We may update this policy as the project evolves. Changes will be committed to the repository and reflected on this page with an updated date.
