# Cookies and privacy choices > Understand essential, analytics, and advertising cookies on the Spacebrain website and change your preferences at any time. Canonical: https://help.spacebrain.ai/account/cookies-and-privacy/ Last modified: 2026-09-09T00:00:00.000Z Choose which optional cookies and tracking technologies the Spacebrain website may use. You can browse with essential cookies only, or allow analytics and advertising measurement separately. This guide covers **spacebrain.ai**, the public marketing website. The signed-in app has separate analytics preferences. This is a practical companion to our [Cookie Policy](https://spacebrain.ai/cookie-policy/) and [Privacy Policy](https://spacebrain.ai/privacy-policy/). ## At a glance [#at-a-glance] | Category | What it does | Your choice | | ------------------------------------- | ---------------------------------------------------------------- | ----------------------------------------------- | | [Essential](#necessary-cookies) | Remembers your privacy choices and supports requested functions. | Always active. | | [Analytics](#analytics-cookies) | Helps us understand visits, interactions, and website errors. | Optional. | | [Advertising](#advertisement-cookies) | Measures campaigns and signups associated with our ads. | Optional. Personalized advertising is disabled. | ## Necessary cookies [#necessary-cookies] The popup calls this category **Essential**. These records remember your decisions, including a refusal of optional tracking. You cannot turn them off using the category controls. Your browser can block or delete cookies, but then your saved choice may not persist. | Cookie | Purpose | Storage period | | -------------------------------------------- | ---------------------------------------------------------------------------------------------------------- | --------------------- | | `sb_privacy_v1` | Stores your analytics and advertising choices and when you saved them. | 180 days from saving. | | `sb_ads_consent` and `sb_signup_ads_consent` | Carry an advertising grant or refusal into signup. These are preference records, not ad click identifiers. | 180 days. | Spacebrain can share these preference cookies across its subdomains so the advertising choice is available during signup. This does not enable analytics in the signed-in app. Account sign-in and security storage are outside this marketing-website inventory. ## Analytics cookies [#analytics-cookies] Analytics is optional. When you allow it, Google Analytics and PostHog help us understand page visits, navigation, interactions, and errors. These tools may process browser identifiers, page paths, timestamps, and device information. Website session recording is disabled. Google Analytics uses cookie families such as `_ga` and `_ga_*`. PostHog uses identifiers and event state in cookies and local storage, including the `ph_*` family. Google Tag Manager delivers the Google tags. For storage periods and provider references, see the [Cookie Policy storage table](https://spacebrain.ai/cookie-policy/#cookie-storage). Cookie lifetimes can vary with provider configuration and browser limits; local storage does not have an automatic browser expiry. Turning Analytics off stops future optional website analytics under that choice. It does not automatically erase data a provider has already received. ## Advertisement cookies [#advertisement-cookies] The popup calls this category **Advertising**. It is optional and controls **advertising measurement**: understanding which campaigns and ad clicks lead to signup. Personalized advertising remains disabled. With your permission, Spacebrain can store campaign details, a landing-page path, a referrer origin, and ad click identifiers when present. Google may receive an ad click identifier and signup confirmation to measure our ads. This measurement does not include your email address or workspace content. | Cookie | Purpose | Storage period | | --------------- | ------------------------------------------------------------------ | ------------------------------------------------------ | | `sb_attr_first` | Remembers the first recorded campaign or ad attribution. | 180 days. | | `sb_attr_last` | Remembers the most recently recorded campaign or ad attribution. | 90 days. | | `_gcl_*` | Google advertising measurement when the corresponding tag is used. | Depends on the tag and browser; see the Cookie Policy. | Advertising and Analytics are separate choices. You can allow one and leave the other off. Turning Advertising off clears Spacebrain's first- and last-touch attribution cookies and stops future optional measurement under that choice. It does not automatically delete information previously received by Google. ## Change your cookie choices [#change-your-cookie-choices] No account or subscription is needed. 1. Visit [spacebrain.ai](https://spacebrain.ai/) and select **Privacy settings** in the footer. If the top notice is visible, you can select **Manage cookies** there instead. 2. Expand a category to read its explanation. Essential is always active; Analytics and Advertising have separate switches. 3. Select **Save choices**. Or select **Reject optional** to turn both optional categories off, or **Accept all** to allow both. Reopen **Privacy settings** to check the saved switches. Your choices apply to the browser where you made them and are remembered for up to 180 days. Another device or browser may need a separate choice. ## Why the notice may not appear [#why-the-notice-may-not-appear] The top notice stays hidden after you save a valid choice. You can still reopen the controls from the footer. Clearing preference cookies or reaching their expiry may cause the notice to appear again. If your browser sends **Global Privacy Control**, Spacebrain keeps optional website tracking off. The notice stays hidden and the optional switches are disabled while that signal is active. Closing the notice with **×** only dismisses it for the current page. It does not accept optional cookies or save a new choice. ## Common questions [#common-questions] ### Can I browse after rejecting optional cookies? [#can-i-browse-after-rejecting-optional-cookies] Yes. Rejecting optional tracking leaves essential website operation available. ### Does accepting the terms also accept cookies? [#does-accepting-the-terms-also-accept-cookies] No. Accepting the Terms of Service or acknowledging the Privacy Policy does not grant optional website tracking permission. ### Are these the same as my app preferences? [#are-these-the-same-as-my-app-preferences] No. The signed-in app's analytics preferences are separate. This popup controls the marketing website and the advertising permission carried into signup. ### My choice is not being remembered. What should I check? [#my-choice-is-not-being-remembered-what-should-i-check] Check whether your browser blocks cookies, clears them on exit, or is using a private session. Also check whether Global Privacy Control is active. You can continue with optional tracking off. For help, [contact support](/troubleshooting/contact-support/) with your browser name and the control that did not behave as expected.
