Cookie policy
Version 2026-11-01-v3 · 1 November 2026
What we store in your browser or on your device, what for and for how long. It applies to Klusted, Pat, Melty Clocks Ads and the Melty Clocks website.
In short. Melty Clocks products (Klusted, Pat, Melty Clocks Ads and the Melty Clocks website) only use technical cookies and storage, needed so you can sign in, we can remember your theme and preferences, and the service works. We do not use analytics, advertising or tracking cookies, whether our own or third-party, on the websites, the console or the apps. The free plan's ads do not use cookies either: they are chosen from your question at that moment, on our servers. That is why we do not show a cookie banner: the rules exempt strictly necessary cookies from consent. If we ever added others, we would ask you first and update this page.
1. What they are
A cookie is a small file that a site stores in your browser. “Local storage” (localStorage and sessionStorage) works in a similar way: it keeps data on your device without sending it to our servers. This page covers both together.
2. Cookies we use
| Name | Where | What for | Duration |
|---|---|---|---|
better-auth.session_token (over https it may carry the __Secure- prefix) | app.klusted.com | Keeps you signed in. It is read-only for the server (HttpOnly) and is not sent to other sites (SameSite=Lax). | Up to 7 days, or until you sign out |
| Console session cookie (same format as the one above, specific to that site) | console.klusted.com | Keeps you signed in to the API console. It is created when you open the console from your account; it does not share scope with the app cookie. | Up to 7 days, or until you sign out |
klusted_cmp (over https, __Secure-klusted_cmp) | klusted.com and the app | Anonymous, signed identifier for the model comparison on the public website: it keeps your conversation with the comparison and applies its usage limits. It is created when you use the comparison and deleted when you claim the result in an account. | 30 days |
enterprise_sso_binding (with a security prefix) | app.klusted.com, only on the company sign-in path | Only if your organisation uses single sign-on (SSO): it ties the sign-in process to your browser to prevent impersonation. | 10 minutes |
| Advertiser portal session cookie (same format as Klusted's, specific to that site) | app.meltyclocks.com | Keeps the advertiser signed in. Only the server can read it (HttpOnly) and it is not sent to other sites. | Up to 7 days or until you sign out |
| Internal panel session cookie (same format, specific to that site) | admin.meltyclocks.com | Only for authorised Melty Clocks staff; no user or advertiser ever sees it. | Up to 7 days or until you sign out |
3. Local storage on the web app and the console
These keys store interface preferences in your browser. They contain no passwords and are not used to track you.
| Key | What for |
|---|---|
klusted.web.theme, klusted.web.contrast | Remember whether you prefer the light, dark or system theme, and the contrast. |
klusted:space:v1:…, klusted.console.space, klusted:ide:space:v1 | Remember the space (personal or team) you chose. |
klusted.payRoute.… | Remember how you prefer to pay for usage (for example, with your plan or your balance). |
klusted.chat-tools.… | Remember the tools you added to a chat. |
klusted.creation-panel.width, klusted:ide:agent-dock:v1 | Remember the width and position of panels. |
klusted.agent.selected, klusted.agent.accepted.… | Remember the selected agent and the changes you have already accepted. |
klusted.console.handoff.state (sessionStorage) | Check that you started the handover of your session to the console. It is deleted once used or when you close the tab. |
The public landing page (klusted.com) stores no cookies or storage of its own, except the comparison cookie if you use it. The Melty Clocks website (meltyclocks.com) stores no cookies or storage of its own: the contact form is sent to our servers without cookies and the news box stores nothing on your device. Any interface preferences the advertiser portal keeps (for example, the language) stay in your browser and are not used to track you. The “No ads” switch and your area are stored in your account, not on your device.
4. Mobile and desktop apps
The mobile app keeps the link to your account and your preferences (such as the theme) in the phone's secure storage. The desktop app uses the storage of the web engine it includes, for the same technical purposes described above. Neither includes analytics or advertising tools, and neither uses the device advertising identifier. The free plan's ads are chosen on our servers. If you turn notifications on, your device registers a notification identifier (see the Privacy policy).
5. Ads, tracking links and third-party services
- Click tracking link. When you click an ad, the link passes through one of our servers to count the click and takes you to the advertiser's site. In that step we store no cookie or data on your device: the click code travels only in the address.
- The advertiser's site may use its own cookies; they are governed by its own policy and we do not control them. The advertiser terms forbid using the link to place cookies before the person accepts them on their site.
- Stripe. When you pay (a Klusted plan or a balance top-up in Ads), we send you to Stripe's page, which has its own cookies needed for security and payment, governed by its own policy.
- We load no third-party advertising or analytics scripts on our pages.
6. How to control them
You can view, block or delete cookies and storage from your browser settings. If you block the technical ones, you will not be able to sign in or stay signed in, and some preferences will not be remembered. Signing out of Klusted removes the session cookie.
7. Changes and contact
We will update this page if the cookies or the rules change. Questions: support@klusted.com (Klusted and Pat) or support@meltyclocks.com (Melty Clocks and Melty Clocks Ads).
