Cookies Policy.
What we set, and why.
LexVio.ai uses a small number of cookies to keep you logged in, remember your preferences, and measure how the product is used. We do not use third-party advertising cookies.

1. What is a cookie?
A cookie is a small text file stored on your device by your browser. Cookies allow a site to recognise your device on subsequent visits and remember settings. Similar technologies include local storage, session storage, and pixel tags — we treat them under the same policy.
2. Categories we use
Essential — required for the Service to function (login, security, fraud prevention). Cannot be disabled.
Preference — remember your settings (theme, language). You can disable these in your browser; the Service will still work but will reset your preferences each visit.
Analytics — help us understand which features are used and where the Service struggles. Set only with your consent, requested via banner on first visit. You can withdraw consent at any time from Settings → Privacy.
We do not set marketing or advertising cookies. We do not share data with ad networks.

4. How to control cookies
On your first visit, you'll see a consent banner asking whether you allow analytics cookies. Your choice — together with when you made it and which version of this policy it was made against — is stored in your browser's local storage (key lexvio:consent) until you change or clear it. You can change it any time from Settings → Privacy after signing in, or by clearing this site's stored data in your browser, which makes the banner ask again.
Most browsers also let you block or clear cookies entirely. See your browser's documentation: Chrome, Firefox, Safari, Edge. Blocking essential cookies will prevent you from logging in.
5. Do-Not-Track and Global Privacy Control
We honour the browser's Do-Not-Track (DNT) setting and the Global Privacy Control (GPC) signal — when either is set, analytics cookies are not loaded regardless of banner state, and the consent banner is not shown (there is nothing left to ask).
6. Changes
We may update this policy. Material changes will be notified by banner on next visit. Date of last update shown above.
