Open4IDCookie Policy
Last updated: October 21, 2026
This Cookie Policy explains how Open4ID uses cookies and similar technologies on https://open4id.com (the "Site") and in the developer dashboard. It should be read together with our Privacy Policy.
Cookies are small text files that a website stores on your device. Similar technologies include browser local storage, which keeps data in your browser rather than sending it with every request.
Summary
- We do not use advertising or cross-site tracking cookies.
- We do not currently use third-party analytics on the Site.
- We use browser local storage to remember your language and to keep you signed in to the dashboard.
- Our hosting and security providers may set strictly necessary cookies.

Storage we use
The table below lists the cookies and local storage keys set by Open4ID.

Our hosting and security providers may set short-lived strictly necessary cookies to route requests, apply rate limits and block malicious traffic. They are not used to track you across other websites.
If we introduce analytics or other non-essential cookies, we will update this page and ask for consent where the law requires it before setting them.
Managing cookies
You can block, delete or restrict cookies in your browser settings, and clear local storage through your browser’s site data controls. Blocking strictly necessary storage may sign you out of the dashboard or reset your language choice.
Most browsers let you review and delete stored data for individual sites. See the help pages for Chrome, Safari, Firefox and Edge. Because we do not use advertising cookies, there is no advertising opt-out specific to this Site.
Do Not Track and similar signals
Some browsers send "Do Not Track" or Global Privacy Control signals. Because we do not use cross-site tracking or advertising cookies, these signals do not change how the Site behaves.
Changes to this policy
We may update this Cookie Policy when our use of cookies or storage changes. We will publish the new version on this page with an updated date. If a change requires consent, we will ask for it before applying the change.
