Privacy Policy

Effective 2026-07-17. This site is operated by Nullzeiger GmbH, Köchlistrasse 28, 8004 Zürich, Switzerland, in accordance with the Swiss Federal Act on Data Protection (FADP/revDSG) and, where applicable, the EU GDPR.

What we collect

Nothing personal, by default. This site sets no cookies and runs no third-party trackers or advertising. We do not collect names, emails, or profiles from visitors.

Technical data

The site is delivered via Cloudflare's content delivery network. Cloudflare processes technical connection data (such as IP addresses) transiently to serve and secure the site. See Cloudflare's privacy policy.

Analytics

If we introduce analytics, it will be self-hosted, cookieless, and aggregate-only (no cross-site tracking, no personal profiles), and this policy will be updated first.

MIDI access

The practice tool will request browser MIDI access to read notes from your instrument. What you play is processed in your browser; performances are not transmitted to us unless a future feature explicitly says so and you opt in.

Payments

When paid plans launch, checkout and billing will be handled by a payment provider acting as merchant of record; their privacy terms will be linked at checkout. We do not store card data.

Your rights

Under the FADP/GDPR you may request access, correction, or deletion of personal data concerning you. Contact: info@nullzeiger.com.
