Cookie & Local-Storage Policy
Last updated: 2026
We keep tracking to a minimum. This page explains what we store on your device and why.
Essential local storage
Necessary for the features you use: your invite/access state (so you don’t re-enter the code), and your academy and product state (display name, lesson progress, replay/behaviour activity, sound and view preferences). These store no marketing identifiers.
Analytics (privacy-light)
Vercel Web Analytics measures aggregate traffic — page views, general region, device type — without cookies that identify you and without selling data. We use it only to learn which content is useful.
What we do not do
No advertising or cross-site tracking cookies, no selling of browsing data, no marketing fingerprinting. If we ever add non-essential cookies, we will ask for your consent first.
Managing storage
You can clear local storage and cookies any time in your browser settings; this will reset your invite state and local progress.
