Privacy Policy

Last updated: March 18, 2026

The short version: Corkscrew is a local desktop application. It does not collect telemetry, analytics, or usage data. Your mods, your data, your machine.

What Corkscrew Does Not Do

Does not collect telemetry or analytics of any kind
Does not track usage patterns, crash reports, or feature usage
Does not send any data to Corkscrew servers (we don't have servers)
Does not display ads or use advertising trackers
Does not sell, share, or monetize user data

Third-Party Services

Corkscrew connects to the following external services only when you explicitly initiate the action (e.g., signing in, searching for mods, checking for updates):

NexusMods API — When you browse, search, or download mods. Requests include your API key or OAuth token and the Application-Name: Corkscrew header. NexusMods may log these requests per their own privacy policy.
NexusMods OAuth — If you sign in via OAuth, Corkscrew uses the standard PKCE flow with a local redirect (http://127.0.0.1). Tokens are stored locally on your machine and never transmitted elsewhere.
Google OAuth — If you use Gemini-powered features, Corkscrew authenticates via Google OAuth. Tokens are stored locally. Google may collect data per their privacy policy.
GitHub API — Used to check for Corkscrew updates, download SKSE builds, and fetch SSEEngineFixesForWine releases. No authentication required. GitHub may log requests per their privacy statement.
Wabbajack CDN & download sources — When installing Wabbajack modlists, Corkscrew downloads archives from various sources (Nexus, MEGA, Google Drive, MediaFire, HTTP mirrors) as specified by the modlist. Each service has its own privacy policy.

Data Stored Locally

All Corkscrew data is stored on your local filesystem:

Configuration — App settings, game paths, bottle locations (JSON files)
Mod database — SQLite database tracking installed mods, load order, profiles
Auth tokens — NexusMods API key/OAuth tokens and Google OAuth tokens, stored in your app data directory
Cached data — Downloaded mod archives, extracted staging files, Vortex extension cache

You can delete all Corkscrew data by removing the app and its data directory. On macOS: ~/Library/Application Support/com.corkscrew.app. On Linux: ~/.local/share/corkscrew.

Auto-Updates

Corkscrew checks for updates via the GitHub Releases API. This is a standard HTTPS request to a public API endpoint. No personally identifiable information is sent. You can disable auto-update checks in Settings.

Open Source

Corkscrew is open source under the GPL-3.0 license. You can audit the complete source code at github.com/cashcon57/corkscrew to verify these claims.

This Website

This website (corkscrewmodmanager.com) is a static site hosted on GitHub Pages. It does not use cookies, analytics, or tracking scripts. The only external request is to the GitHub Releases API to display the changelog and current version. GitHub Pages may collect standard web server logs (IP addresses, user agents) per GitHub's privacy statement.

Changes to This Policy

If this policy changes, the updated version will be posted here with a new "Last updated" date. Since Corkscrew is open source, any changes to data handling are visible in the commit history.
