Keystone AI

Cookie Policy

Last updated:

This Cookie Policy explains how Cornerstone Global Partners Pte Ltd and its related corporations within the CGP Group, including Cornerstone Global Partners Columbus Inc in the United States (collectively, "we," "us," or "our"), use cookies and similar tracking technologies on the Keystone AI product platform at https://gokeystone.ai.

This Cookie Policy supplements our Privacy Policy and applies specifically to the Keystone AI product platform. For cookies used on the CGP Group corporate website, please refer to the CGP Group Cookie Policy at https://www.cgpgroup.com/cookie-policy. For cookies used on the Keystone EOR product, please refer to the Keystone EOR Cookie Policy at https://eor.gokeystone.ai/cookie-policy.

By signing into the Keystone AI platform and using the Service, you agree to the use of cookies in accordance with this Policy and the choices you make through our consent banner or in-product preferences.

1. What Are Cookies?

Cookies are small text files placed on your device by websites or web applications that you use. They are widely used to make products work efficiently, remember user preferences, enable secure authentication, and provide information about how the product is being used.

In a logged-in product context like Keystone AI, cookies play an essential role in maintaining your session, protecting your account from unauthorised access, and remembering your in-product preferences. We also use similar technologies including pixels, tags, local storage, and session storage. For convenience, all of these technologies are referred to as "cookies" in this Policy.

2. Categories of Cookies We Use

Our cookies are grouped into six categories, matching the categories shown in our cookie consent banner. Categories aside from "Necessary" can be toggled on or off in the banner. Under the hood, our consent infrastructure uses Google Consent Mode v2 — see Section 3.

Necessary

Required to enable basic product features, such as authentication, session management, load balancing, and remembering your consent preferences. These cookies cannot be disabled — without them, you cannot log in or use the product securely.

Functional

Help the product provide enhanced functionality such as remembering your in-product preferences (theme, sidebar layout), supporting content sharing, and collecting feedback. These are loaded only after you grant consent.

Analytics

Help us understand how users interact with the Keystone AI platform. Under Google Consent Mode v2, this category corresponds to analytics_storage. These cookies are loaded only after you grant consent.

Performance

Help us understand and improve key performance indicators — including page load times, error tracking, and real user monitoring via Datadog Browser RUM. These are loaded only after you grant consent.

Help provide more relevant advertising and measure campaign effectiveness. Under Google Consent Mode v2, this category corresponds to ad_storage, ad_user_data, and ad_personalization. We do not currently use advertisement cookies inside the product — this category exists so future infrastructure can be activated transparently.

Uncategorized

Cover cookies that are still being reviewed and have not yet been assigned to another category. These are loaded only after you grant consent.

3. Google Consent Mode v2

The Keystone AI product implements Google Consent Mode v2. By default, all consent parameters are set to denied until you grant consent through our cookie banner or in-product preferences. Google tags will not store cookies on your device or send identifiable data to Google until you accept.

If you do not grant consent for analytics or advertising cookies, our Google tags continue to run in a privacy-preserving mode — no identifiable cookies are written and no personal identifiers are sent. You can change your consent preferences at any time through Cookie settings in the footer or account menu.

4. Specific Cookies We Use

Necessary

  • __session (Clerk) — maintains your authenticated session. Duration: session, or extended when you select "Remember me" (per Clerk configuration).
  • __client, __client_uat (Clerk) — client identification and activity tracking for session security.
  • keystone_cookie_consent (Keystone AI) — stores your cookie consent preferences. Duration: 12 months.

Analytics — Google Analytics 4 via GTM-WSKZCRH4

  • _ga — distinguishes unique users. Duration: 2 years.
  • _ga_<container-id> — persists session state for GA4. Duration: 2 years.

Functional

  • sidebar_state (Keystone AI) — remembers sidebar expanded/collapsed state. Duration: 7 days.
  • theme (localStorage, Keystone AI) — remembers light/dark/system theme preference. Duration: until cleared.

Performance — Datadog Browser RUM

  • _dd_s (Datadog) — RUM session identifier. Duration: session.

We do not currently use advertisement cookies inside the product. As of the Last updated date of this Cookie Policy, analytics is limited to Google Analytics 4 via our GTM container.

5. Third-Party Cookies and Services

Some cookies are set by third-party services integrated into Keystone AI:

  • Clerk — authentication and session management. See: https://clerk.com/legal/privacy
  • Google Analytics (via Google Tag Manager GTM-WSKZCRH4) — operated by Google LLC. See: https://policies.google.com/privacy
  • Datadog Browser RUM — performance monitoring. See: https://www.datadoghq.com/legal/privacy/
  • Spott — used when you follow Book a Demo to schedule on spott.io. See: https://spott.io/cookie-policy

We do not control the cookies set by third-party services on their own domains. Please refer to their respective privacy policies for more information.

6. Managing Your Cookie Preferences

Through our cookie banner and footer

Use Cookie settings in the product footer or the consent banner to revisit your choices at any time. You can grant or deny consent by category (Functional, Analytics, Performance, Advertisement, Uncategorized). Strictly Necessary cookies cannot be disabled.

Through your account settings

Logged-in users can manage cookie preferences from the account menu (Cookie settings).

Through your browser settings

Most web browsers allow you to manage cookies through their settings. Note that if you block or delete strictly necessary cookies, you will not be able to log in or use the product.

7. Global Opt-In Default and US State Rights

Our cookie consent banner applies the same opt-in default for all visitors regardless of location: all cookies aside from Necessary are blocked until you grant consent. This is implemented using Google Consent Mode v2, with all consent parameters defaulting to denied until you interact with the banner.

Visitors who are residents of California, Virginia, Colorado, Connecticut, or Utah have additional rights under their respective state privacy laws. To exercise these rights, please refer to our Privacy Policy or contact our Data Protection Officer.

8. Special Considerations for Logged-in Users

  • Your consent choices are stored on your browser and device (keystone_cookie_consent cookie and localStorage) and apply across sessions on that device until you change them or clear site data.
  • Strictly necessary cookies (Clerk authentication, consent storage) cannot be disabled — disabling them would prevent you from logging in or using the product securely.
  • Optional cookies (Analytics, Functional, Performance) load only after you grant the relevant category through our cookie banner or account menu.
  • If you delete your Keystone AI account, personal data tied to your account is handled as described in our Privacy Policy. Browser-stored consent and preference data may remain until you clear site data in your browser.

9. Your Rights

You have certain rights regarding your personal data, including the right to access, correct, delete, and (where applicable) port your data. To learn more about your rights, please see our Privacy Policy or contact our Data Protection Officer at dpo@cornerstoneglobalpartners.com.

10. Updates to This Policy

We may update this Cookie Policy from time to time to reflect changes in our cookie practices, new product features, new third-party integrations, or legal requirements. The Last updated date at the top of this Policy indicates when it was last revised. Material changes will be communicated through an in-product notice or via email to logged-in users.
