Cookies and analytics

Browsing this site sets no cookies and runs no cross-site tracking. Aggregate, anonymous traffic is measured with Cloudflare Web Analytics, which is cookieless and does not fingerprint visitors. Signing in to an Arpeggiator account sets one cookie to keep you signed in; it is never used for advertising or cross-site tracking.

Your account

If you sign in to an Arpeggiator account, we collect your email address; if you add a passkey, its public key only, never a fingerprint, face scan, or private key, which stay on your device; which products you've been granted access to; and a short sign-in and security log. Signing in by email sends a one-time link through Resend, covered by Resend's privacy policy, and account data is stored with Cloudflare, covered by Cloudflare's privacy policy. We access account information only to provide support you request, investigate suspected abuse, or maintain the security of the service; this access is logged. Your account does not store product data itself, such as saved progress or settings; each product keeps that separately.

To delete your account and its data, reach us through the contact page.

Contacting us

If you use the contact form, your message is processed by Cloudflare Pages and Cloudflare Turnstile, both covered by Cloudflare's privacy policy, and by Resend, covered by Resend's privacy policy. The selected product, message type, optional name, optional email, page URL, referrer, user agent, and message are included in the email we receive. We keep contact messages only as long as needed to reply. They are not stored in a database or used for anything else.

Individual products

Products linked from this site, such as ChordSine, are separate applications with their own privacy policies covering their own product data. This policy covers this site and any Arpeggiator account you create.
