Our website and product use five cookies in total: two are necessary (the sign-in session and the choice you make in the cookie notice) and three record your preferences (language, appearance, and the brand you last viewed). We do run web analytics, but on a method that sets no cookie; there are no advertising cookies and no third-party tracking cookies. Before we add any category, we update this page and ask for your choice again.

What a cookie is
A cookie is a small piece of text a website stores in your browser and receives back on your next visit, so it can recognize the same device. It can hold nothing more than a language preference, or it can be used to track you across sites. Today we only do the former.
How we use them
Our cookies fall into two categories:
- Necessary: the site does not work without them. The sign-in session, security, and the choice you make in the cookie notice. This category is always on.
- Preferences: remember the language and appearance you chose, and the brand you last viewed. They are written only when you switch; if you turn this category off, switching still works, it is just not remembered next time.
There are no advertising cookies and no third-party cross-site tracking cookies on the site. We do run web analytics, but on a method that sets no cookie, which is why it does not appear in the list below: daimonia.cn and Daimonia App use a service we host ourselves, daimonia.ai uses an analytics service located outside mainland China, and neither identifies visitors through a cookie. If we add analytics, advertising, or cross-site tracking cookies later, we first put the category and its rows on this page and under the switch in the cookie notice, then ask for your choice again. What the analytics collects and where it is stored is described in the Privacy Policy.
Cookie list
| Name | Category | Purpose | Duration | Scope |
|---|---|---|---|---|
dai-consent | Necessary | Records your choice in the cookie notice and the policy version | 1 year | daimonia.ai and its subdomains; daimonia.cn and its subdomains |
__Host-session | Necessary | Daimonia App sign-in session | Up to 90 days, expiring after 30 days of inactivity; revoked on sign-out | The Daimonia App host only |
dai-lang | Preferences | The language you chose (中文 / English) | 1 year | Same as dai-consent |
dai-theme | Preferences | The appearance you chose (light / dark) | 1 year | Same as dai-consent |
dai-brand | Preferences | The brand you last viewed in Daimonia App, so the next sign-in lands there | 1 year | The Daimonia App host only |
On scope: dai-consent, dai-lang, and dai-theme are set on the parent domain, so a choice you make on daimonia.cn also applies on app.daimonia.cn and vice versa. daimonia.ai and daimonia.cn are separate domains, and browsers do not let them share cookies, so each side asks once.
The captcha component on the Daimonia App sign-in page may keep a small amount of risk-control data in your browser’s local storage to tell a person from a bot. It contains no identity information.
Your choices
On your first visit a cookie notice appears at the bottom left of the page:
- Accept all: turns on preference cookies.
- Decline: keeps only the necessary cookies and clears any preference cookies already set.
- Settings: read each category before deciding.
Until you choose, preference cookies are written only when you switch language, appearance, or brand yourself; browsing on its own writes no preference cookie.
To change your mind, use “Cookie settings” in the footer at any time. Your choice is kept for one year, after which we ask again; a material change to this policy also triggers a new prompt.
Browser controls
You can also view, delete, or block cookies in your browser. Blocking necessary cookies makes it impossible to sign in to Daimonia App and stops language and appearance from being remembered. Settings for each browser: Chrome, Safari, Firefox, Edge.
Changes
When this policy changes, we update the version and date on this page. Before adding any new cookie category, we update this list first and ask for your choice again.
