Privacy policy

Clasmus GmbH (CHE-404.828.543), Strehlgasse 2, 8001 Zürich, Suiza, operator of the “CornerQuiz” brand. Contact: [pendiente: email de contacto del Quiz].

Anonymous play: you don't need to sign up or give your email to play.

Leaderboard: if you choose to appear on the leaderboard, we store your nickname (a pseudonym you choose), your score and your time, linked to an anonymous identifier for your device. It is not your real name unless you type it.

In your browser (localStorage): your streak, stats and progress. This lives only on your device, not on our servers.

Advertising: when we enable ads (Google AdSense), Google may use cookies to serve and measure ads. We manage this via the cookie consent (see below).

Premium payments: if you buy the premium pass, the payment is processed by Paddle (the legal seller), which handles your payment data; we never see your card.

Supabase (database, EU/Ireland servers), Cloudflare (site hosting), Google AdSense (advertising, when enabled) and Paddle (premium payments). We do not sell or rent your data to anyone.

We process data under the GDPR (EU) and the Swiss FADP (nLPD/revDSG), based on consent, legitimate interest (service security) and legal obligations.

We keep the leaderboard while relevant (we prune old leaderboards); purchase invoices for as long as tax law requires; technical logs for 30–90 days.

You can access, correct or delete your data, or object to its processing, by writing to [pendiente: email de contacto del Quiz]. As play is anonymous, to delete your leaderboard entry just tell us your nickname. We handle requests within a reasonable time.

EU residents may lodge a complaint with their data protection authority; in Switzerland, with the FDPIC (PFPDT).

We use HTTPS, row-level security (RLS) in the database, and data minimization: we collect only what's necessary.
