Privacy Policy

What stays on your device

FeatureChain has no accounts. Your puzzle results, streak and stats are stored in your browser’s local storage on your device. Your streak and stats never leave your device — never sent to us, never synced — and clearing your browser data deletes them permanently.

Analytics

If you accepted analytics cookies, FeatureChain loads Google Analytics 4 to measure things like how far players get in a puzzle. GA4 sets cookies and processes data under Google’s own privacy terms. If you declined — or never saw a prompt — no analytics script is loaded at all. You can change your choice at any time by clearing this site’s data in your browser.

We do not collect names, email addresses, or any identifying information, and we do not sell or share personal data.

Third-party content

Artist names and recording credits are curated from MusicBrainz and ListenBrainz. Cover images come from the community-curated Cover Art Archive and are fetched through this site’s image cache. Gameplay search uses our local catalogue; it does not send the songs you type to any of those services.
