Optional analytics

With your permission, JazzValve uses Mixpanel to measure page visits, PDF link clicks and practice interactions, plus a general traffic-source category, such as search, social media or email. When you are signed in, activity is linked to your JazzValve account using an internal account ID so we can understand how activity relates to upgrades. These events do not include your email, URL queries or payment details. Audio playback is not proof of instrument practice.

Rejecting does not affect downloads, practice, sign-in or payments. You can change this choice here at any time. Your permission lasts 90 days in this browser; if storage is unavailable, analytics stays off. Browser privacy signals can keep analytics off even after acceptance. Withdrawing permission stops future optional analytics; it does not automatically delete previously collected events.

Mixpanel’s documented policy retains events for two years. Renewing permission every 90 days does not delete earlier events.
