Cookie Policy
Last updated October 6, 2026
CustomDomain™ uses cookies and similar technologies to run the service, keep it secure and, unless you turn them off, understand how it is used. You can change your choices at any time.
1. The short version
- We use essential cookies to run the service. Optional analytics and marketing cookies are on until you change them.
- Unless you turn it off, we record how you use CustomDomain™ (clicks, scrolling and page views, never what you type other than a domain name) to improve it. That is part of analytics, so the one Analytics switch in Cookie settings covers it.
- A bar at the bottom of our pages offers Confirm and Change. You can change your choice at any time.
- Your choice generally applies across the website (customdomain.ai), the docs (docs.customdomain.ai) and the console (app.customdomain.ai).
- When you are signed in, your choice may be saved to your account so it can follow you to other browsers.
- We may use a first-party visitor id to help us understand how our sites are used.
- If your browser sends Global Privacy Control or Do Not Track, optional cookies are off and we do not show the bar.
2. What cookies are
Cookies are small files a site stores on your device. Similar technologies include localStorage and sessionStorage. Privacy rules in many places, such as the ePrivacy rules in Europe, treat cookies that are strictly necessary differently from other cookies, which is why you can change the optional ones.
3. Your cookie choice
Optional analytics and marketing cookies are on until you change them. Until you do, we store nothing about your choice, and a bar at the bottom of our pages offers Confirm, which keeps them on and remembers it, and Change, which lets you turn either category off. Turning a category off takes effect at once.
We store your cookie choice in a first-party cookie, so that the website, the docs and the console can respect it without asking you again. It may record which categories you allowed, which version of this policy you answered and when.
When you are signed in, we may also save your choice to your account, along with a record of changes, so that it can be applied when you sign in on another browser or device.
If this policy changes in a way that affects your choice, we may ask you again. A choice to turn something off is kept when this policy changes.
4. Cookies we use
The cookies and storage we use can change over time. This table describes them in general terms.
| What | Type | Purpose | Duration |
|---|---|---|---|
| Sign-in and security cookies | Strictly necessary (first-party) | Help keep you signed in to the console and protect sign-in steps. | Usually your session, or a short time for sign-in steps |
| Preference cookies, such as the application you were last viewing | Strictly necessary (first-party) | Remember settings you choose, so the console works the way you left it. | Up to about a year |
| Your cookie choice | Strictly necessary (first-party) | Remembers your cookie choice (see section 3). | Up to about a year |
| First-party visitor id | First-party measurement | Helps us understand how our sites are used (see section 5). | Up to about a year |
| A copy of the visitor id for our product analytics tool | Optional analytics (first-party) | Used by our product analytics tool when it is enabled and analytics is on. | Up to about a year |
| Analytics tools, such as Google Analytics, PostHog and Microsoft Clarity | Optional analytics (third-party tools) | Help us understand which pages and features are used. They may receive technical information such as your IP address, and may estimate your approximate location. PostHog may also record how you use our pages and the console (a session recording): clicks, scrolling and page views, with typed text masked except a domain name you enter. The pages for signing in, resetting a password, verifying an email address, accepting an invitation, billing and agent access are left out of recordings. | Set by each tool. Session recordings are kept for about 30 days. |
| Local and session storage, such as your theme, the campaign link you arrived from, or that you dismissed a cookie notice | Local or session storage (first-party) | Remember preferences and, for a visit, how you arrived. | Until cleared, or until the tab closes |
The website at customdomain.ai may also set its own cookies, for example to run the site and remember your choice, and its cookie policy has more detail. The embedded widget on a customer's site is designed to avoid setting tracking cookies on their visitors.
5. The visitor id
The visitor id is a random identifier we create the first time you visit one of our sites. It is not designed to hold your name or email address. Our event log records basic details about page views, such as which site and page, the referring page and campaign tags. The optional analytics tools in section 4 may receive it while analytics is on.
Separately, and not through any cookie, we may keep the IP address of some requests for security, abuse prevention and support, such as sign ins, domain lookups and the connect widget. The Privacy Policy (section 3.3) says more.
We may use the id to count visits across the website, the docs and the console and, once you sign in, to connect earlier visits to your account so we can see which pages help people get started. It is set whether or not optional cookies are on, because it is first-party measurement, and we do not currently use it for advertising. While analytics is on, a copy may also be sent to PostHog, our product analytics provider, so that its analytics can be matched to ours (see Sub-processors). Deleting your cookies resets it.
6. Advertising and marketing
At present we do not use cookies to show you ads, and we do not sell or share personal information for advertising. Marketing cookies are on until you turn them off, and are used to measure our own campaigns.
7. Browser privacy signals
If your browser sends a privacy signal, Global Privacy Control (GPC) or Do-Not-Track, we treat it as a choice to turn optional cookies off: we do not load optional tools and we do not show the cookie bar. Cookie settings still opens from the footer and says so.
8. Changing your choice
You can change your choice at any time with Cookie settings, which you can find in the console and in the footers of our pages and website. A change generally applies across customdomain.ai and, when you are signed in, to your account. You can also manage or delete cookies and local storage in your browser, which may sign you out or reset your preferences.
9. Changes and contact
We may update this policy from time to time, for example if our use of cookies changes. Questions: [email protected]. See also our Privacy Policy.
