Cookie Policy
The cookies and browser storage kling4.io uses, and how to control them
2026/09/28
Kling4.io is an independent third-party platform. It is not affiliated with, endorsed by, or operated by Kuaishou or Kling AI.
This Cookie Policy explains which cookies and similar technologies kling4.io uses, what each one is for, and how you can control them. It complements our Privacy Policy.
1. What Cookies and Browser Storage Are
A cookie is a small text file that a website stores in your browser. We also use your browser's local storage and session storage, which work in a similar way but are never sent to our servers automatically. Below, "cookies" covers all of these unless the difference matters.
2. Cookies We Use
The tables below describe authentication, preferences, security and analytics storage used by the site. Third-party analytics are loaded when configured; their availability can differ between environments.
Strictly necessary
These keep you signed in and keep the Service secure. Blocking them will sign you out and may stop checkout from working.
| Cookie | Purpose | Duration |
|---|---|---|
kling4.session_token | Keeps you signed in | 7 days, renewed while you use the Service |
kling4.session_data | Caches your session so pages load faster | 1 hour |
cf_signup_token (when Turnstile is enabled) | Carries a Cloudflare Turnstile check that stops scripts from claiming sign-up bonus credits in bulk | 10 minutes |
Cloudflare security cookies (for example __cf_bm) | Set by our hosting provider to tell people from bots | As set by Cloudflare |
On HTTPS the session cookie names may carry a __Secure- prefix. A few short-lived cookies may also be set while you complete Google or GitHub sign-in.
Preferences
| Cookie or storage | Purpose | Duration |
|---|---|---|
NEXT_LOCALE | Remembers your language | 1 year |
active_theme | Remembers the display theme | 1 year |
sidebar_state | Remembers whether the dashboard sidebar is open | 7 days |
g_state | Set by Google's sign-in script to remember that you closed the Google One Tap prompt | As set by Google |
| Local and session storage | Keeps an unsent prompt draft, a generation waiting for you to sign in, notices and banners you have dismissed, and when a pop-up was last shown, so nothing is lost or repeated | Until you clear it; session storage ends when you close the tab |
Analytics
| Cookie | Purpose | Duration |
|---|---|---|
site_ref (and site_referral in local storage) | Records how you first reached us — the referring site, campaign tags, and landing page. It is saved to your account when you sign up, so we can see which channels bring users | 30 days |
_ga, _ga_* (when configured) | Google Analytics: measures visits and feature usage | Set by the analytics service and its configuration |
| Microsoft Clarity storage (when configured) | Usage analytics, including interaction and session analysis | Set by the analytics service and its configuration |
3. Cookies Set on Other Sites
You pay on Stripe's own checkout page, and you sign in with Google or GitHub on their pages. Those services set their own cookies under their own privacy and cookie policies.
4. How to Control Cookies
- Block or delete cookies and site data in your browser settings. Blocking strictly necessary cookies will sign you out and may stop checkout from working.
- To opt out of Google Analytics on every site, install Google's opt-out browser add-on.
- Local and session storage are removed when you clear the site data for kling4.io in your browser.
