Cookie policy
Valyzer sets three first-party cookies and none for advertising or from third parties for their own purposes. Two are necessary for sign-in to work and cannot be turned off without losing the ability to sign in; the third stores your analytics decision and only exists once you have seen the cookie notice. In addition, Cloudflare, our infrastructure provider, may set a security cookie (cf_clearance) when it verifies that a request is not automated; it is strictly necessary and exempt from consent. Aggregate visit counting with Cloudflare Web Analytics uses no cookies (see the privacy policy).
