What Hearwise stores in your browser, and why. Hearwise uses no advertising cookies and no social-network trackers.

Technical cookie

NEXT_LOCALE remembers the site's language (French or English). It is a session cookie: it disappears when you close the browser. It is needed for the site to work and is used for nothing else.

Browser local storage

Your sign-in session, progress, profile, trial state and listening preferences are stored in your browser's local storage (localStorage), so the site works and your games are not lost. No third party reads them.

When you sign out, once everything has reached your account, the browser forgets your progress and profile. You can erase everything by deleting the site's data in your browser.

Audience measurement

Vercel Web Analytics and Speed Insights count page views and measure loading speed in aggregate, without cookies, on the page address alone (no parameters). They do not follow visitors across sites and link no visit to an account.

Your consent

The language cookie and local storage are strictly necessary for the service you ask for; audience measurement stores nothing in your browser and is limited to aggregate statistics. That is why no consent banner is shown. If a tracker requiring consent were ever added, it would only be set after your agreement.
