Cookies and local storage

1. Strictly necessary (always on)

Without these entries the service does not work or cannot protect itself against abuse. They do not require consent, but we tell you about them in the notice at the bottom of the page.

zelio_token · local storage

your sign-in key. Removed when you sign out.

zelio_locale, zelio_locale_explicit · local storage

the interface language and whether you picked it yourself.

zelio_calendar_view, zelio_cal_specialist_id · local storage

the calendar view and the selected specialist, so the calendar opens the way you left it.

zelio_cookie_notice · local storage

that you dismissed this notice, and your category choices.

zelio_device_id · local storage

a random browser identifier created at signup and used only to detect repeated trials (section 4 of the Privacy Policy). Kept until you clear the site data.

zelio_chunk_reload · session storage

a technical marker: after a service update the page reloads once to fetch the new version. Removed when the tab is closed.

2. Analytics and marketing (optional)

Not used at the moment: there are no visitor counters, advertising pixels or third-party cookies. If we add them, they will only be switched on after your explicit consent — in the cookie notice or its settings ("Customize").

3. How to manage them

You can delete cookies and site data in your browser settings. Note that after clearing them you will need to sign in again, and the language and calendar view return to their defaults.
