Privacy Policy

Effective Date: January 5, 2026

Information We Collect

Vizcogs collects minimal information necessary to provide our vinyl collection visualization service:

Information from Discogs

When you connect your Discogs account via OAuth, we access:

Your Discogs username and user ID
Your public collection data (albums, release information)
Marketplace statistics for releases in your collection

We do not access your Discogs password, payment information, or private messages.

Automatically Collected Information

Session tokens: Temporary OAuth tokens stored in HTTP-only cookies to maintain your login session
Local storage: Your preferences (theme, sidebar state) and cached marketplace data stored in your browser
Analytics and advertising data: Information collected by Google Ads for analytics and advertising purposes, including cookies, device identifiers, and browsing behavior (see Advertising section below)

Community Leaderboard Data

When you connect via OAuth and load your collection, we automatically collect and store aggregated statistics for our Community leaderboard:

Your Discogs username and avatar URL
Collection size (vinyl count)
Top genres and genre diversity score
Year range of releases (e.g., "1972-2024")

By default, your profile appears anonymously on the leaderboard (username obscured as "j***n"). You can choose to make your profile public in Settings, which reveals your full username and links to your collection. You can also opt out entirely to remove your data from the leaderboard.

Information We Do NOT Collect

We do not store your full collection data (individual albums) on our servers—only aggregated statistics
We do not collect your Discogs password or payment information

How We Use Your Information

We use the information we access to:

Display visualizations of your vinyl collection
Fetch marketplace data (pricing, rarity) for releases in your collection
Remember your display preferences between sessions
Display your aggregated collection statistics on the Community leaderboard
Display relevant advertisements to support the Service
Analyze usage patterns to improve the Service

Collection data processing happens in your browser. We act as a pass-through to the Discogs API and do not retain your full collection data on our servers—only aggregated statistics for the Community leaderboard.

Advertising and Analytics

Vizcogs displays advertisements to support the free operation of the Service. We use Google Ads and related Google services for advertising and analytics.

Show ads that may be relevant to your interests
