Cookie Policy
Last updated: March 2026
1. What Are Cookies
Cookies are small text files that are placed on your device (computer, tablet, or mobile phone) when you visit a website. They are widely used to make websites work more efficiently, to provide a better user experience, and to provide information to the website operators.
Cookies can be "persistent" (they remain on your device until they expire or you delete them) or "session" cookies (they are deleted when you close your browser). They can also be "first-party" cookies (set by the website you are visiting) or "third-party" cookies (set by a different domain than the one you are visiting).
2. How We Use Cookies
Grantverse uses cookies for several purposes, including authentication, payment processing, analytics, and remembering your preferences. Below is a detailed list of the cookies we use:
| Cookie Name | Provider | Purpose | Duration | Type |
|---|---|---|---|---|
| next-auth.session-token | Grantverse (NextAuth) | Authentication and session management. Keeps you signed in and verifies your identity across page requests. | Session / 30 days | Essential |
| __stripe_mid | Stripe | Payment processing and fraud prevention. Used by Stripe to identify your device for secure payment transactions. | 1 year | Essential |
| __stripe_sid | Stripe | Payment session management. Used by Stripe to manage your payment session and prevent fraud. | 30 minutes | Essential |
| _ph_* | PostHog | Product analytics. Tracks usage patterns such as pages visited, features used, and user interactions to help us improve the platform. Note: We currently configure PostHog with in-memory persistence, meaning these cookies may not be set in practice. | 1 year (if set) | Analytics |
| _clck, _clsk | Microsoft Clarity | Session replay and heatmap analytics. Records anonymised user interactions (clicks, scrolls, page navigation) to help us understand how users experience the platform and identify usability issues. | 1 year / Session | Analytics |
| cookie-consent | Grantverse | Stores your cookie consent preferences so we can respect your choices across sessions. | 1 year | Preferences |
3. Managing Cookies
You have control over the cookies stored on your device. You can manage your cookie preferences in several ways:
Cookie Consent Banner
When you first visit Grantverse, you will see a cookie consent banner that allows you to accept all cookies or limit cookies to essential ones only. You can change your preference at any time by clearing your browser's cookies and revisiting the site.
Browser Settings
Most web browsers allow you to control cookies through their settings. You can typically find these options in the "Privacy" or "Security" section of your browser's settings menu. Common options include:
- Viewing and deleting existing cookies.
- Blocking all or certain types of cookies.
- Setting your browser to notify you when a cookie is being set.
- Configuring your browser to automatically delete cookies when you close it.
Please note: Disabling essential cookies may cause parts of Grantverse to function incorrectly or become unavailable. For example, if you block the session authentication cookie, you will not be able to sign in to your account.
4. Third-Party Cookies
Some cookies on our platform are set by third-party services that we use to provide and improve our services:
PostHog
We use PostHog for product analytics to understand how users interact with our platform. PostHog cookies (prefixed with _ph_) collect anonymised usage data such as pages visited, features used, and user flows. This data helps us identify areas for improvement and prioritise new features. You can learn more about PostHog's data practices at posthog.com/privacy.
Microsoft Clarity
We use Microsoft Clarity for session replay and heatmap analytics. Clarity records anonymised user interactions such as clicks, scrolls, and page navigation to help us identify usability issues and improve the platform experience. Clarity does not collect passwords, payment details, or other sensitive form inputs. Clarity cookies are only set when you consent to analytics cookies. You can learn more about Clarity's data practices at clarity.microsoft.com/terms.
Stripe
We use Stripe for secure payment processing. Stripe sets cookies to detect and prevent fraud and to manage payment sessions. These cookies are essential for processing payments securely. You can learn more about Stripe's cookie usage at stripe.com/privacy.
5. Changes to This Cookie Policy
We may update this Cookie Policy from time to time to reflect changes in the cookies we use or for other operational, legal, or regulatory reasons. We will update the "Last updated" date at the top of this page and, where appropriate, notify you of significant changes.
We encourage you to review this Cookie Policy periodically to stay informed about our use of cookies.
